It's been a cloudy few weeks where I am.. so I decided to dig up my first light ever and reprocess the data I had. At the time (in 2021) I had an uncooled ASI294MC, Rainbow-Astro RST-135 mount, and a pretty shoddy Celestron AstroMaster 130 Newt that I didn't know how to collimate.

 

I still have many issues in the reprocessed data (including a huge reflection I don't know how to remove), but I'm pretty happy with how much the tools (and perhaps my processing skills) have improved!

If you're bored like me, let's see your reprocesses of your first light :-)

well, this is my first light with my first and only (real) telescope https://www.astrobin...ction&nce=32422

 

the "Original revision" was the first time it was processed (like a couple months ago)

 

the "Final", is my latest. (processed like 1-2 weeks ago)

That "reflection" is the diffraction spike from Alnitak, just off the left of your screen. It is the rightmost star of Orion's belt, and the bane of astrophotographers worldwide. Aside from clone-stamping, I'm not sure how you'd be able to get rid of it.

I tried to mask that area and selectively dim it in various ways, but I couldn't get a good result. I eventually gave up. Maybe there will be AI based tools in the future that will make this easier :-)

Or maybe we'll get lucky and Alnitak will go supernova
