Hello,
Tonight was clear despite the bad forecast so I gave my setup a try.
Was using a quite recent nightly build of Windows client. Two CCD cameras.
Let me start with the problem first.
-- Live View doesn't work for ZWO ASI1600MC when in 16bit mode. Getting white frames with some noise.
Preview (16bit) works fine. Live View in 8bit works fine.

Secondly, a couple of issues I had before got resolved (or almost resolved)
-- FITS histogram/image look much better now
-- Polar Alignment now works (it wouldn't refresh images before). Now it refreshes but stopps refreshing after about 3 min saying that it was done with the procedure (I didn't double check this one).

(Oh, great! KStars just crashed! I was shooting the Owl Nebula at the moment. It was running for about 4 hours. I did many different things with it. Just crashed while I was writing this post (same PC)).

Thanks!

White frames mean that the pixel values are all zero. What gain were you using with the Live View? I usually set the gain to 800 or so when using the Live View. When I start imaging I set it back to 139 and offset to 21 (unity gain).

I didn't go as high as 800 but tried 560. Again, it works at 8bit.
I'll play some more tonight...
Thanks!

Any news on this topic?
I don't have an electronic focuser yet and do my focusing in live view. But in the middle of the night, I often forget to set the mode back to 16 bit and wake up with a whole night's worth of 8bit images.
If only entering live view would temporarily set 8bit mode and revert back to 16bit on exit...

No need to switch mode to 8bit. Streaming works in 16bit. INDI downconverts when it streams.

Had that been changed? I also had lots of problems with 16bit stream, and stopped using it, but just last week found out that it nicely works now, which is really great! :D
