Wow! It's about 2.5x the field of view of my Ultrastar-C. High Point Scientific has it for $1280 US (wait listed). There's a guy on Astrobin who has three beta test shots with it (120s exposures, many stacks) www.astrobin.com/gear/59635/zwo-asi071mc-cool/

Looks really nice. But if the AP guys are complaining about for size and processing time - we might be in trouble.
Just have to go for long subs? Like the infinity.

You could bin it to reduce the file size. Even 2x2 binned though, it's much bigger than my field of view. I was seeing that DonBoy on CN regularly bins the 1600 and it's still in color (must be software binning). My guess is it would be similar with the ASI071C
But for the price an Infinity or Ultrastar would probably get you most of what you want. There's only few objects that are big enough to take up the whole view but you could always use a smaller scope for those objects.
I like the Ultrastar for my newtonian because of it's 1.25" form factor means it will slip deep into the focuser. I didn't buy it though. I won it in a raffle at OPT. If I didn't win it, I don't know if I would have eventually purchased one. My next purchase will probably be a Lodestar X2M. The big pixels mean it will work well for my newtonian and my Skywatcher 12" Dob.

Seems like just another Imaging camera.

Kinda thinking,that it's reading image cameras,,why can't we get a really sensitive camera with variable film rate that can go from a fast exposure to slow for dso,, yeah and can we get it with a fan and peltier..

And internal stacking,, so it's plug and play,, straight in to usb port, switch on an few adjustments and live in minutes,,

Yep. 'REALTIME' live would be nice! We aren't asking for much

Thing is,,,why can't we,,, we can modify a mere Samsung CCTV camera to give us great video by removing bog standard or filter,, bang on a fan and cool it,,it's twice as good,,you have stuck a tec on your sammy and it great,,, it may be old hat these days but it was simplicity at it's best,,not running through two or three software packages to get an image,, I'm not dissing latest kit,, but it can be a royal pain in the neck to get correct . Please give us a dedicated camera. How hard can it be.. Awe no, I can see me building a camera next just to see if it can be done.

Total inspiration to all, with his analogue cameras.

robj and chris ... yes, great realisation in that statement rob "about twice the FOV of Ultrastar" .... perfect combo approaching! Imagine a Hyperstar'ed 8" SCT on GEM mount with both cams in a special flip mirror style attachment (so you can have both cams on the one scope). Hyperstar'ed very widefield / bright objects (071C), or a bit less but still quite widefield / dimmer stuff (Infinity or Ultrastar). And stick the flip device and two cams onto the back of the SCT for high mag / bright stuff (071C), or really high mag / dim stuff (Ulstrastar / Infinity).
Be interested in how the 071C goes.

Hey brilliant ! I'm selling the kids for medical research. I'm thinking the asi1600 cooled. But that'll have to wait till i get a new mount and an imaging newt and ... Then one of these ... www.photometrics.com/products/scmos/prime95B95% QE. 1.3e read noise. And 11um pixels. 16 bits. Pity is only 1.4MB.

First light with the ASI071MM-cooled. Done in sharpcap, didn't subtract darks or do flats (as it kept crashing on me - which I think was my mistake). Some amp glow down along the bottom which should be sorted with some darks. M42 2x60sec. NGC3392 1x 60sec. Running Chicken 8x 60sec. Had cooling on at 0C. Getting there with it, but still haven't figured it all out yet.

Hey Chris , I was just on CN , and looked at your new set up and images, thought I would just post here to say hi and like your work. Good to see your getting the new mount out and giving it a run, and also some clear weather.
Nice regards David.

Thanks Dave. Got the new bits a few weeks ago and this is the first night I've been able to try it out. Take a while to get used to it

Yeah those are really nice, Chris. Curious about 60s exposure - seems like a lot for a bright object like M42.
