I keep being impressed by the ASI533MC Pro - unlike the 294MC Pro I used to have, it is not fussy, it takes nice darks and nice flats, and it just works well overall, even here in Tokyo.

 

I aimed it, along with my Vixen R200SS @ F3.8 Newt and EQ6-R, at the Needle Galaxy over three nights, getting around 1,550 x 30s frames and pruning down to around 1,130 frames with the PixInsight Subframe Selector.

 

Incidentally I have recorded my preprocessing workflow in PI here, and my processing here if anyone is interested in the nitty gritty (plus then if anyone has suggestions regarding what I do for processing).

 

C&C welcome!

 

Cheers,

 

Yannick

After reading about the problems you were having with the other camera, I'm glad you now have a camera that works well for you. Very well, judging by the results. Beautiful image!

Fantastic work Yannick. Again, I still don’t know how you do it producing such great work from Bortle 9 skies and with 4 digit number of subs! I think I’d kill my PC!!

Thank you guys!!@Kevin: yes it's such a huge difference at least in a white zone. I had so much trouble with the 294, although it gave some amazing results from Death Valley and Yosemite.
@AnakChan: yeah thousands of subs are hard on the PC... I've been thinking about building a Threadripper setup with Linux and Optane drives on it for faster PixInsight processing, but that would be quite an investment!

Cheers,

Yannick

Wow, from Tokyo??  I was thinking of getting a nice Newtonian for some fast imaging.   This gives me some inspiration!   Thanks Yannic!   You sliced right through that light pollution!  Any LP filter used?  

Excellent!

So are you suggesting for anyone that has the 294, to consider the 533?

@skycamper: I was very afraid of getting of Newt because of the collimation - the only reason I went for one is because that R200SS is advertized as not needing user-side collimation. At this stage, this has proven to be true. No LP filter used, just a simple Lum filter from Optolong! You can indeed cut through light pollution... but the shot noise that has been injected by the LP will always remain...

 

@Ballyhoo: not exactly - but I would suggest anyone who lives in Bortle 7+ and has had trouble with the 294 think about the 533. I have a full review of the 533 (and I spend some time comparing it to the 294) here, if you are interested: https://www.youtube....h?v=lfQ_tPoPaLk . It is in general far better behaved than my 294 ever was.

Did your camera require a lot of back focus to work at prime?

Fleep

The 533 with most scopes is the typical 55mm back focus and its super forgiving/easy to get working compared to anything else i've ever used.
