Description

This is the third and probably the last summer "All-Backyard" project for 2019 - all data, Ha, S-II, O-III and R/G/B are imaged from my bortle class 9 backyard over 12 nights. The amount of data is about the same as my previous project. But the seeing over these nights were not good at all. I can see the mean values from light sub-frames vary from 20%-30%.

This time, PixInsight was not used for the color blending. Instead, the color combination is done in Photoshop. I am pretty thrilled about how easy this way is - the result changes in real-time when the scroll-bars is moving! Very efficient and instinctive.

Overall, pretty happy about the result. The resolving power of the 85mm refractor really shines. There are actually more details that I believe my processing skills didn't pull out. I decided to post the "full" version and two cropped versions in separate uploads - they all have enough details to be standalone.
