Description

This is an image of Crescent nebula and Soap Bubble nebula in True color (firstimage) and HOO with rgb stars (B rev). The third image is a close up of Soap Bubble.

Well i have a wee problem, and thats my color deficiency. I can recognize some colors, and some look exactly the same to me. This makes calibrating colors a bit difficult for me. Combining narrowband data into rgb is a hellish inferno to me. So I need to sit somebody (usually my poor sister) beside me to be my eyes as I calibrate the colors.

That's why my colors look a bit funky sometimes.

First Image is Narrowband mixed with RGB

Second Image is HOO with RGB stars
