Description

Many thanks to Yizhou (https://www.astrobin.com/users/yzhzhang/) for his knowledge of astrophotography and patience with mentoring me. I would not have seen this deep in space without his kind help.

First attempt while adjusting the 13035FF. Not much data and post-processing is a little over. Combined data from 130 f/6.3 and 100 f/5.5. Suprising to see a lot of detail from such small aperture.

L: 45 x 300s (bin 1x1, gain 0) = 3h45min
R: 22 x 300s (bin 1x1, gain 0) = 1h50min
G: 18 x 300s (bin 1x1, gain 0) = 1h30min
B: 21 x 300s (bin 1x1, gain 0) = 1h45min
Ha: 9 x 600s (bin 1x1, gain 100) = 1h30min
total: 10h20min
