Description

Part 2 - Color
I finally finished IC2162 a few days ago after several cloudy days. I was able to capture a total of 110 x 90 second frames over three nights. The RGB image had much less noise than did the Ha most likely due to more RGB frames. Since the DSLR does star color really well and this field has many colorful stars, I focused on keeping them intact after getting the nebula looking respectable. I did a 50% luminosity blend with Ha in PI and then another blend in PS followed by blending in the RGB star field.

From my Ha post about IC2162, Stellarium only has IC 2162 listed it is actually a star forming region approximately 8000 light years away at the top edge of the Orion constellation, above Betelgeuse towards Gemini. It is composed of 5 Sharpless HII emission objects; from left to right, Sh2-254 (large and diffuse), Sh2-257 (bright middle object), Sh2-256 (small and just above), Sh2-255 (brightest nebula a.k.a. IC 2162), and finally Sh2-258 (not visible in the Ha version).

I pleased how this image turned out and as an added surprise, Sh2-258 is visible in the color image. It is small but there. The star field contains several colorful blue and yellow stars of all sizes. The bright blue magnitude 6.65 star (HIP 29616 A) to the right of the nebula is listed as a double star while a bright yellow magnitude 6.35 star (HIP 29326) is on the left.

Anyway, hope you enjoy my DSLR image, it certainly was interesting doing this again. Fortunately my ASI1600 is back so I will be switching out the cameras now all that is needed is clear skies!
