3-23 Seagull HaO3Combo NoL-3Ha-4OIII STCr1HubJ4Shr
This is an enhanced version of the Seagull nebula (IC2177) image that we captured on 23 March 2020. This version minimizes the stars and shows enhanced nebulosity. The nebula is a large star forming region which is 100 light years wide. The nebula is 3800 light years away, located on the border between Monoceros and Canis Major constellations.
The nebula is full of hot young stars that power the atomic hydrogen in the surronding area to give off its characteristic deep red hydrogen Alpha emissions. The large, roughly half circular shape seen in our image is classified as Sh2-296 while the head of the Seagull is listed as Sh2-292. It also includes contains a couple of open star star clusters within it.
We captured this image with our Stellarvue Access 80mm scope and an H-Alpha modded Nikon D5300 camera. We used a 0.8x focal reducer and a dual narrowband filter to bring out the deep red and blue/green emissions. The effective focal length was 448mm.Capture details - ISO 1600, f5.6 and a total of 140 minutes of integration (70x2min). We used the bicolor technique in APP to combine H-Alpha and OIII channels to result in enhanced colors seen our image. Enjoy!
