ZWO ASI094MC Pro CMOS Camera User Review
Posted 23 November 2017 - 01:24 PM
Nice review! Seems to go hand-in-hand for how I found the QHY367C (same chip). Ain't the new CMOS cameras wonderful?

thanks Paul, at least someone finds it useful :-) yes they are, especially the download time is something that is fascinating (along with the 36mpix resolution)...
ppl always say they want big chip and when there is then they say it's expensive :-) this hobby is not cheap at all!

Thanks for the review!
I just took delivery of one. Haven't had a chance to use it yet. Can't wait.

Pavel, thanks a lot for the great review!
I can't decide what to choose - IMX094 vs IMX128. What was your motivation?

Thank you Pavel for the informative review.
I noticed on the ZWO page that there is a sample image of the Sadr region that shows a pretty pronounced halo around Sadr.
Have you run into the same issue on bright stars?
I'm trying to understand if that might be caused by the optical window of the camera before I drop a chunk of cash on it.

David, 094 is newer and my motivation was that I have the same image scale (because I myself say that color camera with bayer matrix is essentially a mono camera of double size of the pixel) as with my mono full frame that has 9um pixels... therefore I do not loose any detail (I gain a bit) from what I have and it is right in color... and even a 50% downsize (to make stars look better, smaller, sharper) results in nice pixel width and height...
Andy, I did shoot 4 different objects, but none had any seriously bright star in the FOV, but in spite of that I did not had any issues with any halo nor reflections - I'd expect to have these problems with a AR-only window so that was my motivation to directly put the filter I know that works best the uv ir cut from baader that cuts 420 to 680 and it paid off - my data looks great to me :-)

Thank you Pavel.
I suspect that the halo was caused by the Optlong L-Pro filter. I did a bit more research and I saw similar halos in images taken with different cameras but same filter.

So this ASI camera over the QHY367?
(if both were the same price) which is better? I'm leaning toward one or the other and can't figure out which to get.

Ron: I had many QHY ccd and cmos cameras in the past 9 years. And I always had some kind of problems or issues. Most recently I prefered QHY over ZWO in case of the monochromatic panasonic chip because ZWO was new in the DSO cameras and did not meet my requirements (I told them what they do wrong). Then ZWO had all kind of problems that I anticipated. In the meantime I had issues with my QHY. Then ZWO became more mature and nowadays I can fully recommend them. They try to improve always... it takes time, but they do listen to customers and their needs and do their best to improve their product line...
as with every camera maker - there are lovers and haters of everyone :-)
My reason for prefering QHY in the past was also that I hoped that after qhy's 20+ years of experience they will not make silly mistakes again, but again my recent most camera was faulty...
BTW so far I made lot more images then I presented on my gallery link, but I only have 2-3 nights of data of few hours only - not enough to post process them... so it takes me a while to produce something (but by the end of the week I shall process the 21P commet).

I've had excellent support with ZWO. I had a OSC and it would frost up - they took it back and exchanged it for a 1600mmc. I over powered that camera by mistake and blew out the cooler, I sent it to the dealer who sent it to china under warranty and I had it back in 10 days! BLEW ME AWAY.
I see the ZWO has (I believe 2 year warranty). I was looking at a slightly used QHY367 that is around same price... Dealer said 90 day warrantly. That's kinda scary on a 4K camera.
I was totally sold on 367, but the warranty made my pause. I also asked why it was used (so soon) and they said the camera was bad. They took it back and ordered him another but but he decided to go with the ZWO.
(I think he tried both) and sent this one back. After looking at examples today for the first time, I'm leaning toward the ZWO. They might be newer but are going ALL OUT TO BE KNOWN AS THE BEST... support has been outstanding. ONLY ZWO problem I knew of was the one I had (others had it too) the 071? or what ever model OSC would freeze up and a grid pattern would shot up in the images. I know others had that too, but that's the only issue I've heard about from ZWO. same price USED vs NEW - 2 year warranty vs QHY's (weird one different time for sensor, and other parts?) seemed to petty to me like their do worried about problems.
Leaning toward the ASI.
