Auriga Clusters and Nebulas (Askar230 Ra).jpg
This is a framing of the rich array of star clusters and nebulas in central Auriga. The large star cluster Messier 38 is at top left, with the small cluster NGC 1907 just below it. The smaller star cluster Messier 36 is at left. M38 is often called the Starfish Cluster, while M36 is the Pinwheel Cluster.
The complex of star cluster Stock 8 and IC 417 is left of centre, with the small emission nebula NGC 1931 between it and M36. The large nebula at lower centre is IC 410 with the star cluster NGC 1893 embedded in it. The large nebula at right is IC 405, aka the Flaming Star Nebula, with a mix of red emission and blue reflection nebulosity. The faint streak of nebulosity right of M38 at top is Sharpless 2-230. The tiny intense patch of red nebulosity at upper left is Sharpless 2-235.
The colourful asterism of stars between IC 410 and IC 405 is variously known as the Little Fish or the Flying Minnow., made of the stars 16, 17, 18 and 19 Aurigae.
The field of view is just under 9° by 6°.
This is a stack of just 7 x 4-minute exposures with an Askar FMA230 astrograph (230mm focal length at f/4.5), and filter-modified Canon Ra camera at ISO 800. However, no filters were employed here. Nebulosity was brought out using successive curves with luminosity masks generated by Lumenzia. All alignment and layering in Photoshop. Taken from home on January 27, 2022. Autoguided with the MGEN3 guider and dithered. No LENR or dark frame subtraction was employed on this mild winter night. Some light haze in some frames added the star glows. This was a stack of the best 7 frames out of 30 taken this night!
