My stack vs seestar's stack, where can I improve?
Same data, same integration time
Taken with my s30pro
The first image is my stack and process, the second was done on the seestar
For my process I stacked in Deep sky stacker, then Proc in Siril
I did the basics, color calibration, background neutralization, remove green noise , then stretch, deconvolution (actually I forgot if I did this before or after stretching) then some contrast and color curve edits in snapseed

Gso coma corrector and canon rebel t7, will it work? Back focus question
So context
I have a printed telescope with a 114 f3.9 optics
I'm preparing to rebuild it to accept a 2" focuser, giving me the ability to finally get a coma Corrector
The gso one seems good, and within my budget
But I'm concerned about back focus
Since my telescope is homemade, Its beyond trivial to adjust the distance between the primary and secondary mirror
However Im concerned about the distance between my camera and the corrector
I'm not sure if my gear would be compatible, or if I need some additional equipment to make it work
My camera is a canon rebel t7, and i have a 1.25" t mount
I'll need to configure that to fit 2" obviously, but I'm not sure how to best do that for the Corrector
Any advice?

M101, 264 minutes over 3 nights
I think I'm pretty close to getting the most out of this particular target
4 hours 20 minutes is also right up there with my longest integration time
My last Orion picture with my other telescope was around 4 hours over 2 nights

Gso coma corrector
I'm needing a coma corrector for my 114 F/3.9 reflector, and since I'm already planning on upgrading to a larger telescope in like 3 years, I'm needing a cheap one in the interim
Back focus is absolutely not a problem since my telescope is completely diy, I can adjust as needed
Anyway I found one on ali express for $120, its sparse on details, so I need to ask, does gso make multiple types of coma correctors for different focal lengths, or is it a one size fits most?
Are there better cheap coma correctors?
Should I check the used Market for better deals?

M101
This is just a first pass, I didn't have more than an hour to gather data, I'm hoping to get another clear night soon so I can get more images, then I'll try processing the RAWs in Siril
No lp filter
Bortle 5
30s subs
EQ mode

I'm not a novice at astrophotography, I have another telescope, so the seestar is for the nights I can't be bothered to lug my gear out of my apartment, and also to act as a second source of data to get 2 targets at the same time
I've already figured out eq mode, and doing a few hours of Leo triplet
Eventually I'll start working with the raw data In Siril like my regular ap
