Add to Cart Add to Lightbox Download
The large star-forming region of IC 1396 in Cepheus, taken September 4, 2018 from home in southern Alberta. The wide field includes the bright orange star Mu Cephei, or Herschel’s Garnet Star, at upper left. The Elephant Trunk Nebula is just right of centre. North is at top.

This is a stack of 9 exposures: 5 x 4 minutes at ISO 1600 and 4 x 8 minutes at ISO 800, all with the 77mm f/4 Borg Astrograph and filter-modified Canon 5D MkII, an old but very excellent camera! With the 300mm focal length and full frame camera the field is about 7° by 4°.

Star diffraction spikes added with AstronomyTools actions. StarShrink filter also applied.

Focused with Bahtinov mask. Autoguided with SG4.
