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.
