M33 Esprit 120 with ASI294MC

[rodrigol]

This is first light of an Esprit 120 with flattener and my ASI294MC Pro. It's a quick processing job in PI only of 20 x 120s with 20 x 120s Darks only. I've tested autofocusing with a Sesto Senso 2, which worked well, but my steps are too small and it took more than 20 minutes to get to the lowest HFR this night. I'm overall very pleased with the result. My trusty CGEM-DX is doing nicely after I readjusted the backslash setting. My only grudge is that CPWI insists in parking on the opposite side of where I want and at one point it started the park routine after I had closed the observatory, sending everything crashing with the roof. I manged to get to the clutches just in time. This was taken the day after that episode... 

 

Comments are much appreciated (I know about the gradients and the big black dust speck at the bottom 6:30 position, which has been found and removed now) 🤔

Well that's come out nice, I have just done 16 hours on this and apart from richer colours all round, mine don't show a great deal more, must be doing something wrong, my scope is 115mm so similar to your.

Wow - 16 hours?!? How long are your exposures? If there is a single frame with some cloud it will ruin the whole stack even if registration and integration are successful.

I just do 4 minutes, could easily do more with the decent dark sky I have here. This is collected this year and last year. I put 14 hours of data on the site for people to have a play if they want. I don't claim to be expert or anything but some that don't have cooled camera and dark sky may get some benefit and indeed see if there is an improvement over their DSLR's. As I collect them in batches it give me chance to look at the frames on a night by night basis, all told there will be about 10 nights and most the time I'm at the scope anyway, our weather is generally better than the UK.
