NGC/IC Objects { 555 images } Created 19 Feb 2011

This Gallery contains objects (nebulas, star clusters and galaxies) in the New General and Index Catalogues of J.L.E. Dreyer in the late 1800s. The catalogues serve as a list of most of the sky's deep-sky objects accessible to the backyard astronomer. Most of these images will also appear in the other Deep-Sky Galleries under Nebulas, Star Clusters, etc. This Gallery does NOT contain any of the Messier objects.

To search for specific objects, simply the catalog number, or type NGC&1499, for example, to search for NGC 1499.

$This is the faint but large planetary nebula known as the Medusa Nebula, but officially Abell 21 or PK 205+14.1 in Gemini. It was discovered in 1955 and was once classified as a supernova remnant. The very sparse open cluster NGC 2395 is at upper right from the nebula. The nebula is thought to be 4 light-years across and 1500 light-years away. This is a blend of filtered and unfiltered exposures: a stack of 4 unfiltered at ISO 1600 for 8 minutes each, and a stack of 8 filtered shots at 10 minutes each and ISO 3200, through the Optolong L-Enhance filter. All with the red-sensitive Canon EOS Ra camera through the SharpStar 100QII astrographic refractor at f/5.8, a quadruplet lens apo refractor. All stacked, aligned and blended in Photoshop.$

$A framing of the field around the bright white star Altair (lower left), and the orange giant star Tarazed above, with the dark nebula complex B142 (lower dark lane) and B143 (the top pair of dark lanes), together known as Barnard's E. These are all in Aquila. This is a stack of 12 x 4-minute exposures at ISO 800 with the Canon Ra camera, on the Starfield Optics Géar90 EDT f/6 refractor with its 0.8x Reducer/Flattener for f/4.8 effective. Taken from home October 23, 2022. On the AP Mach1 mount and autoguided and dithered with the Lacerta MGEN3 autoguider.$

$This is a 140° panorama of the northernmost section of the Milky Way, from Auriga at left to Aquila at right. Perseus, Cassiopeia, Cepheus and Cygnus are across the centre. I added in labels on the mosaic for the constellations, and major nebulas and star clusters. Surrounding the panorama is a collage of close-up images of the major emission nebulas (and one dark nebula) pointing to the area in the wide-field mosaic. The close-ups were shot with various astrographic telescopes such as the William Optics RedCat 51mm and Sharpstar 61, 76 and 94mm refractors, usually employing filters such as the Optolong L-eNhance and IDAS NBX. The background panorama was shot on October 30, 2021, but the close-ups were shot on various nights over two years from 2019 to 2021. The panorama is a stitch of 4 segments, each a stack of 8 x 4-minute expsures at ISO 800 with the Canon Ra and with the RF 28-70mm lens at 28mm and f/2.8. It was on the Star Adventurer Mini tracker. Another panorama of 4 segments taken through a Kase StarGlow filter and layered in added the glows on the bright stars.$

$Horsehead Nebula region with NGC2024 and 2023, and B33 dark nebula. Stack of two 15-minute exposures with Canon 20Da, at f/6 with 5-inch AP apo refractor, ISO400, and Long Exposure Nosie Reduction ON in camera. Ambient temp was about -3° C. Taken Dec. 29, 2005. Noise reduction applied at RAW conversion stage, and Noise Ninja applied to both layers at start before processing and to single flattened layer at end after processing and stretching. Image showed dithered dark areas initially after Levels adjustment but this smoothed out after flattening of original image and adjustment layers.$

Belt and Sword of Orion (135mm 6D).jpg
$The Belt and Sword region of Orion, with the Orion Nebula, Messiesr 42 and 43, at bottom. Below the left star of the Belt, Alnitak, is the famous Horsehead Nebula, while above it is NGC 2024, aka the Flame Nebula. At very top left is Messier 78, while part of Barnard’s Loop arc across the field at left. The field is filled with other faint red emission and blue reflection nebulas. The large loose open cluster Collinder 70 surrounds the middle star of the Belt, Alnilam. The field is similar to that of binoculars. This is a stack of 16 x 2- to 3-minute exposures with the filter-modified Canon 5D MkII at ISO 800 to 1250 and 200mm Canon L-Series lens at f/2.8. Taken with the Fornax Lightrack tracker as part of testing. Taken from home on January 8, 2019 in a clear couple of hours between haze patches, and while battling dying batteries for the drive and camera. Diffraction spikes added with Astronomy Tools. Main images stacked with Median stack mode to eliminate satellite trails from geosats that populate this area of sky.$

$The Belt of Orion with the Horsehead Nebula at botton, the dark nebula set in the bright emission nebula IC 434. The nebula at left of the Zeta Orionis (aka Alnitak) is the Flame Nebula, NGC 2024. The reflection nebula at upper left is the M78 complex with NGC 2071. The other Belt stars are Alnilan (centre) and Mintaka (upper right). The field contains a wealth of other blue reflection and red emission nebulas. Taken from Australia, March 2014 with the Borg 77mm astrographic apo refractor (330mm focal length) at f/4.3 for a stack of 5 x 10 minute exposures with the filter-modified Canon 5D Mark II at ISO 800.$

$This is a wide-field portrait of a set of nebulas with colourful names but rendered here in monochrome: The Bubble Nebula at upper left; the Lobster Claw Nebula below it (somewhat obvious for its shape); the Cave Nebula at upper right; and the Wizard Nebula at bottom. The small round nebula above the Wizard is Sharpless 2-152. Just below it and very small is Sh2-148. The star cluster right of centre is NGC 7419. The Bubble Nebula's spherical bubble is a little lost at this scale. It lies below the star cluster Messier 52. The Bubble is also NGC 7635. The Lobster Claw is Sharpless 2-157 and is sometimes called the Californietto. The Cave Nebula is Sharpless 2-155, while the Wizard is Sharpless 2-142 but also known as NGC 7380 though that designation applies to the star cluster associated with it. All are located on the Cassiopeia-Cepheus border. North is more or less up in this portrait orientation. This is a stack of 12 x 16-minute exposures with the SharpStar 61mm EDPH refractor with its reducer at f/4.4, and with the Canon EOS Ra camera at ISO 3200, with a clip-in Astronomik 12nm H-alpha filter to block all but red H-a light for a monochrome portrait. Luminosity masks with Lumenzia helped bring out the faint nebulosity. The initial exposures were taken in moonlight. I added a slight blue colour grade for artistic effect.$

$A mosaic of the region in Cassiopeia and Cepheus containing the main nebulas: the Bubble Nebula (NGC 7635) at lower left, and the Cave Nebula (Sh 2-155) at upper right. At left is also the bright Messier open cluster M52. The small yellowish cluster at right is NGC 7419. The small cluster at lower centre is NGC 7510. The small nebula just left of centre is NGC 7538. This is a mosaic of 4 panels, each segment being a stack of 10 x 6-minute exposures taken over two nights with the TMB 92mm apo refractor at f/4.4 with the Borg 0.85x field flattener/reducer and the filter-modified Canon 5D MkII at ISO 800.

$The Coal Sack and Jewel Box Cluster area on the east side of Crux, the Southern Cross. The Coal Sack, which to the eye looks like a large dark patch, under photography breaks up into small patches, the darkest just south of the Jewel Box Cluster, here just below and left of Becrux, or Beta Crucis. Other star clusters in the scene are NGC 4852 at top left, Trumpler 20 at right. and NGC 4609 at lower right. The small intensely red area is the nebula Gum 46. This is a stack of 5 x 8 minute exposures with the Borg 77mm astrographic apo refractor (330mm focal length) at f/4.3 and with the filter-modified Canon 5D Mark II at ISO 800. Taken from Coonabarabran, Australia, March 2014.$

$The colourful region in and around the Coathanger asterism in Vulpecula the Fox. The grouping is not a star cluster per se, though it is catalogued as one, Collinder 399. It is also known as Brocchi's Cluster. A true star cluster, NGC 6802, is located at the east (left) end of the Coathanger, as the small clump of stars. The area is also rich in faint nebulosity, notably: the Sharpless 2-83 reflection nebula complex above the Coathanger, and the small, round Sharpless 2-82 emission and reflection nebula below the Coathanger. The large area of red emission nebula at bottom right is not catalogued or labelled in any of the star atlases I have, including the Millenium Star Atlas and Uranometria. However, the small round red "nebula" on the bottom edge of the large nebula is actually a highly reddened globular cluster, Palomar 10. This area of the Milky Way is rich in dark nebulas and absorbing dust, yellowing the fields. This is a stack of 10 x 5-minute exposures through the SharpStar 61EDPH II refractor with its flattener/reducer at f/4.5 and the red-sensitive Canon Ra, though with no filter employed here. The mount was the little Star Adventurer GTi portable GoTo mount undergoing testing, and autoguided with the ZWO ASIAir and its little 30mm guidescope, with the Air also controlling the Ra and performing dithering moves between each exposure. The guiding worked very well. No darks or LENR were applied here, but the stacking averaged out the thermal noise hot pixels on this fairly warm autumn night, September 27, 2022. All stacking and alignment with Photoshop. A mild Orton Glow effect added with Luminar AI, plus an application of PK Actions Dark Detail Hard action (a form of high-pass sharpening), two somewhat opposing effects -- i.e. fine sharpening plus overall softening. But the result does punch up the nebulosity, as does some luminosity masked curves adjustment layers from TK Actions and Lumenzia. Noise reduction was with RC Astro's Noise XTerminator.$

Coathanger Cluster Cr399 (SS61 Ra).jpg
$Taken with 4-inch apo refractor at f/4.5 with Canon 20Da camera at IS0800 for 5 minutes. Stack of two exposures. One layer median filtered and gaussian blurred to enhance glows around stars.$

Coathanger CR399 (4in f4.5).jpg
$The asterism known as the Coathanger, aka Cr 399, in Vulpecula, at upper right here. The faint blue reflection nebula above it is Sharpless 2-83; the small reflection nebula at bottom is Sh-2-82. The small open cluster off the left tip of the Coathanger is NGC 6802. The Coathanger asterism is a fine one for binoculars. The 7.5 x 5° field is close to a binocular field of view. This is a stack of 12 x 6-minute exposures with the SharpStar 61mm apo refractor at f/4.5 and with the Canon R6 at ISO 1250. Taken from home Sept. 30, 2021. Diffraction spikes added with Astronomy Tools actions.$

Coathanger with NGC 6802 (SS61 R6).jpg
$Several types of deep-sky objects are represented here: an emission nebula, dark nebulas, and star clusters, in this rich field in Cygnus. The field frames the bright and magenta Cocoon Nebula (at lower left), aka IC 5146, at the end of the dark nebula B168, aka The Dark Cigar, which itself is southeast of the bright but sparse star cluster Messier 39 at upper right. The field is also wrapped in faint red emission nebulosity. A dimmer smaller star cluster, Platais 1, sits above M39. This is a rich field about 6° by 4°, embedded in the main band of the Milky Way in northern Cygnus. This is a blend of: a stack of 8 x 6-minute exposures at ISO 1600 through a clear Astronomik UV-IR cut filter, layered with a stack of 11 x 12-minute shots at ISO 2000 through an IDAS NB1 narrowband filter for the red H-alpha nebulosity. All were with the 76mm SharpStar apo refractor with its matching flattener/reducer for f/4.4, and with the red-sensitive Canon EOS Ra camera. Autoguiding and inter-frame dithering was with the MGEN3. No darks or LENR were applied here on this cooler autumn night. All stacking, alignment and blending with Photoshop. I brought out the faint nebulosity with the use of luminosity and color range masks created with Lumenzia and Zone System Express 7. Diffraction spikes added for artistic effect with Astronomy Tools Actions. A mild Orton glow added with Luminar AI for fun.$

$The large star cluster in Coma Berenices catalogued as Mel111, at right, and two prominent galaxies at left: the Needle Galaxy, NGC 4565, at lower left, and NGC 4559 at upper left. NGC 4494 is between NGC 4565 and the star cluster at bottom. This is a stack of 19 x 4-minute exposures with the Sky-Watcher Evolux 82ED refractor and its 0.9x Corrector/Reducer for a focal length of 477mm at f/5.8. The Canon EOS Ra was at ISO 800. Images taken as part of testing this telescope in April 2022.$

$The large star cluster in Coma Berenices known officially as Melotte 111, at right, with two of the most prominent galaxies in Coma at left: NGC 4559 at top and the Needle Galaxy, NGC 4565, at bottom. Several other fainter galaxies are in the field. I shot this April 2, 2021 on a less-then-ideal hazy night as a test of the new SharpStar 94mm EDPH refractor telescope and its matching field flattener/reducer. The high haze added the star glows and accentuated the star colours, so did make for a nice image in the end. And despite the haze, galaxies as faint as 14th magnitude are recorded, such as tiny NGC 4562 below the Needle Galaxy. This is a stack of 10 x 6-minute exposures at ISO 800 with the Canon EOS Ra, autoguided on the Astro-Physics Mach 1 mount with the Lacerta MGEN3 stand-alone autoguided set to dither 5 pixels between each exposure. The field of view is about 3.3° x 5°.$

$The large star cluster in Coma Berenices known officially as Melotte 111, at right, with two of the most prominent galaxies in Coma at left: NGC 4559 at top and the Needle Galaxy, NGC 4565, at bottom. Several other fainter galaxies are in the field, including NGC 4494 between the Needle Galaxy and the star cluster, but looking very star-like at this image scale. I shot this April 11, 2021 on a fairly clear night as a test of the new SharpStar 94mm EDPH refractor telescope and its matching field flattener/reducer. A bit of passing haze added a touch of star glows. There is a version of this same field shot a week earlier in hazy skies with much fuzzier stars. This is a stack of 20 x 6-minute exposures at ISO 800 with the Canon EOS Ra, autoguided on the Astro-Physics Mach 1 mount with the Lacerta MGEN3 stand-alone autoguided set to dither 5 pixels between each exposure. No dark frames or LENR were applied. The field of view is about 3.3° x 5°.$

Coma Berenices Galaxies (SS94mm EOS ...jpg
$The immensely rich galaxy cluster Abell 1656 in Coma Berenices with two giant elliptical galaxies NGC 4889 and NGC 4874 at its heart. Both are about 11th magnitude. The face-on spiral galaxy NGC 4921 is at lower left at 12th magnitude; the tilted spiral NGC 4839 is at lower right, also 12th magnitude. The field is peppered with dozens of fainter galaxies from the NGC and PGC catalogues, all around 13th to 15th magnitude. The two bright blue stars are 7th magnitude. I shot this on a less than ideal night, with haze moving in, so this is a stack of only 6 x 8-minute exposures at ISO 1600 with the Canon EOS Ra through the Astro-Physics 130mm EDT refractor at f/6 with the 6x7 field flattener. Shot May 5, 2021. Haze prevented more images to smooth the noise more. Autoguided with the MGEN3 stand-alone autoguider.$

Coma Berenices Galaxy Cluster (130mm...jpg
$The Coma Berenices star cluster, aka Mel 111, with a smattering of galaxies, taken under dark skies on a spring evening. The edge-on galaxy NGC 4565 is at left. I shot this as a test of the William Optics RedCat 51mm f/5 astrographic refractor (which provides a focal lengthof 250mm). This was on the iOptron SkyGuider Pro tracker, a popular portable mount to use with the RedCat. I used it unguided for a set of 2-minute exposures. Of the 20 exposures, 12 were relatively untrailed and so were selected for stacking for this image. This is a stack of 12 x 2-minutes at ISO 1250 with the Canon EOS Ra. Stacked and blended in Photoshop CC. The little RedCat astrograph is very sharp to the corners. The field is about 8° by 5.5°.$

Coma Berenices in Dark Sky (WO51 EOS...jpg
$The Coma Berenices star cluster, aka Melotte 111, at right, with two prominent galaxies at left: NGC 4559 at top left and edge-on NGC 4565 at bottom left. This is a stack of 6 x 8 minute exposures with the SharpStar 76mm apo refractor with the EDPH field flattener for f/4.5 and with the Canon EOS Ra at ISO 800. Diffraction spikes added for effect using Astronomy Tools actions.$

$The Coma Berenices star cluster, aka Mel 111, with star glows added from haze in the sky to accentuate the star colours. The edge-on galaxy NGC 4565 (the Needle Galaxy) is at lower left; the spiral galaxy NGC 4559 is at upper left. Several other smaller NGC galaxies are in the field, which is similar to the field of view of binoculars. This is a stack of 7 x 4-minute exposures in a clear sky blended with 2 x 4-minutes with the haze moved in, all with the Sharpstar 61mm EDPHII refractor at f/4.5 and Canon EOS Ra camera at ISO 1600 (with no filters used). Taken April 1, 2022 from home.$

$The large star cluster in Coma Berenices called Mel111, accompanied by several galaxies, notably the edge-on NGC 4565 at lower left and the spiral NGC 4559 at upper left. The field of view is 7.5° by 5°, so similar to binoculars. This is a stack of 12 x 6-minute exposures with the Sharpstar 61mm EDPH II telescope at f/4.6 with its reducer (for a focal length of 280mm), and Canon EOS Ra at ISO 800. Sub-frames dithered with the MGEN3 auto-guider. No darks applied. Diffraction spikes added in post for artistic effect.$

$This is a wide-field framing of the heart of the Coma-Virgo cluster of galaxies in the northern spring sky, with galaxies galore in the frame, including a dozen Messier objects. The field is 7.5° by 5°, so similar to binoculars. The faintest galaxies here are about 12th magnitude. Just below the centre is the Marakarian's Chain of galaxies including the Messier galaxies M84 and M86. The giant elliptical M87 (famous for having its central black hole imaged) is below and to the left of the Chain. There are many other Messier objects in the field — At top right around the blue star 6 Comae is the trio of M98 (at the far edge), M99 (below and right of 6 Comae) and M100 (at top). At left are M88, M91, M90 amd M89. At bottom left is M58 and M59. M60 just squeaks onto the frame. This is a stack of 10 x 6 minute exposures with the SharpStar 61 EDPH II refractor at f/4.5 and the Canon EOS Ra at ISO 100. This is a single framing, not a mosaic. Taken from home April 24, 2022. Haze moving in spoiled exposures taken after this set. Dithered with MGEN3 autoguider; no darks applied.$

$A wide-field image of the Coma-Virgo Galaxy Cluster including the Messier galaxies around the star 6 Comae at top right, down to the galaxies of Markarian’s Chain at bottom left, including several other Messiers. The field is about 4 degrees high and 6 degrees wide. This is a stack of 5 x 8-minute exposures through the SharpStar 76mm EDPH refractor and with the SharpStar flattener/reducer for f/4.5, and with the Canon EOS Ra at ISO 800. An additional exposure taken through light cloud layered in added the star glows. Clouds prevented more exposures.$

$The well-known Double Cluster (aka NGC 884 and NGC 869) framed at upper right to include two of its companion star clusters, NGC 957 at upper left and Trumpler 2 at lower left. Dotted through the field of young blue stars are numerous aging yellow giant stars. And the gradation in sky colour from the clearer, bluer sky with more stars at right to the dustier, yellower sky and fewer stars at left is subtle but obvious here, from interstellar dust in this part of the Milky Way. This is a stack of 8 x 6-minute exposures at ISO 800 with the Canon Ra and on the StarField Optics Géar80 apo refractor with its matching reducer/flattener for f/4.8. Taken from home through breaks in passing clouds as part of testing of this new scope. No darks or LENR used, just dithering between each frame using the MGEN autoguider.

$The famous Double Cluster (NGC 869, right and NGC 884, left) in Perseus, in a wide-field shot that includes the nearby stars clusters NGC 957 to the left, and Trumpler 2 at bottom left. The large and sparse cluster Stock 2, aka the Muscle Man Cluster, is at upper right. The field is filled with yellow supergiant stars. The field of view is similar to that of binoculars. This is a stack of 20 (!) x 3-minute exposures with the SharpStar 61EDPH II refractor with its reducer/flattener at f/4.5, and the Canon Ra at ISO 800. Autoguided with the MGENIII, on the Star Adventurer GTi mount taken as part of testing the mount. A slight camera tilt from the reducer's rotator mechanism being a bit loose produces slightly soft stars on the left side of the frame. Taken from home September 25, 2022.$

$The famous Double Cluster (NGC 869, right and NGC 884, left) in Perseus, in a wide-field shot that incl;udes the large and sparse cluster Stock 2, aka the Muscle Man Cluster, is at top, looking here as if it outlined by a square border of stars. The field is filled with yellow supergiant stars. This is a stack of 12 x 5-minute exposures with the SharpStar 76EDPH refractor with its reducer/flattener at f/4.5, and the Canon R5 at ISO 800. Autoguided with the MGENIII, on the Star Adventurer GTi mount taken as part of testing the mount. Taken from home October 1, 2022.$

$The nebulosity around the central star of Cygnus, Gamma Cygni (aka Sadr), with the nebulosity generally taking the catalog name IC 1318, The bright open star cluster above Sadr is NGC 6910; the cluster at right, above centre, is IC 1311. The prominent patch of dark nebulosity at right, below centre, is B 343. Messier 29, M29, is at the bottom edge, left of centre. This is a panoramic stitch of 2 segments, each a stack of 4 x 7-minute exposures at ISO 1600 with the filter-modified Canon 5D MkII, shooting through the TMB 92mm apo refractor at f/4.5 with the Borg 0.85 flattener/reducer. Stitched with Photoshop. Taken on a night with some high clouds, so some frames have haze, which adds the natural sky glows. Diffraction spikes added in post with Astronomy Tools Actions.$

$A portrait of the complex of emission nebulas in central Cygnus near the bright star Gamma Cygni (at left). The field includes the IC 1318 complex around Gamma Cygni itself and the Wolf-Rayet arc of nebulosity, NGC 6888, aka the Crescent Nebula, at right. The sparse star cluster Messier 29 is at bottom. This was through the SharpStar 94mm apo refractor at f/4.4 and with the Canon EOS Ra. It is a blend of 6 x 6-minute exposures at ISO 1600 through an Astronomik UV-IR-Cut filter for the base image, and a stack of 4 x 12-minutes at ISO 3200 through IDAS NB1 and Optolong L-eNhance filters for the enhanced red nebulosity, plus 6 x 12-minutes at ISO 3200 through Optolong L-eXtreme and IDAS NBZ filters which contribute only the enhanced cyan OIII emission, all taken as part of testing the filters. Normally, using four filters would not be required! Autoguided and dithered on this warm summer night with the Lacerta MGEN3 autoguider. No darks or LENR applied as the dithering effectively eliminated the thermal noise speckling which was prominent on the individual sub-frames. Taken from home August 13, 2021. All stacked, aligned, and blended in Photoshop.$

$This is the region of central Cassiopeia containing a rich assortment of deep-sky objects: The so-called Ghosts of Cassiopeia nebulas at top, the Owl Cluster, aka the ET Cluster, at bottom, and the Pacman Nebula at right. The Ghosts of Cassiopeia are the magenta/cyan reflection and emission nebulas officially called IC 59 and IC 63. Both are reflecting the light of bluish Gamma Cassiopeiae, aka Navi. The "Ghost" name for these objects is a recent appellation. See https://apod.nasa.gov/apod/ap191025.html The star cluster at bottom is NGC 457, with smaller NGC 436 above it. It is variously called the Owl Cluster or the E.T. Cluster. The emission nebula at right is the Pacman Nebula, NGC 281, below the stars Eta (Achird) and Alpha (Schedar) Cassiopeiae. The blue star at far left is Delta Cassiopeiae, aka Ruchbah. It along with Gamma and Alpha form the middle three stars of the W of Cassiopeia. The field here is 7.5° x 5°, similar to binoculars. This is stack of 8 x 16-minute exposures through an IDAS NB1 nebula filter to bring out the faint nebulosity, blended with a stack of 15 x 8-minute exposures with an Astronomik UV/IR Cut filter for a white light normal colour image. All with the Canon Ra (at ISO 1600 for the NB1 filter shots and at ISO 1000 for the normal shots) through the SharpStar EDPH 61mm refractor at f/4.5. All stacking, alignment and blending with Photoshop. No LENR or darks applied, just inter-frame dithering to eliminate thermal noise specks which were prominent in the long high-ISO filtered shots. Autoguiding and dithering was with the MGEN3 stand-alone autoguider. Faint nebulosity was brought out with luminosity mask adjustments with Lumenzia.$
