So, I was doing some testing between 8 bit and 16 bit mono, as well as bewteen avi and ser in bit (surprise, 16bit ser is the best by a wide margin), but unfortunately my last test capture before going for the time lapse was the 8 bit ser video, so this time lapse is also unfortunately only in 8 bit, which caused a sizeable loss in detail as well as some crazy gradients in the background.  Lesson learned, always double check your settings before starting a project, lol.  Seeing had degraded by the time I was done with test and single image captures, so the finer details were kind of doomed anyways.

 

The small active region was the only semi-bright spot I could see on the main disc of the sun, with a small possible spot forming maybe?

Fantastic animation.   Are you using the ZWO 294 in bin1 mode?  What frame rate do you achieve with smaller ROI?

Thanks everyone!

 

Fantastic animation.   Are you using the ZWO 294 in bin1 mode?  What frame rate do you achieve with smaller ROI?

I do use the 294 in bin1 when doing full disk images, but for the time lapse I had it in bin2 + 4x telecentric .  The 294 had its best bit depth in bin2, and would also be oversampling if in bin1 with the 4x.  In bin1, even with a mild ROI, frame rate is pretty abysmal, usually between 8-13 fps.  With incredibly small ROI, or in bin2, I can get either its max framerate of 25 or very close to it.

 

When it comes to framerate the 294 isn't really ideal for solar, but the massive real estate of its sensor is something I really, really like, and it doesn't have any of the fixed sensor noise my 178mm suffers from, which makes processing less of a crapshoot.  I'm in the process though of setting up a longer focal length solar imaging system, and that huge sensor of the 294 will help me keep a wider FOV even at longer magnification as we head towards solar maximum and structures/interesting areas get larger and larger.

Gorgeous animation, excellent processing on that and wonderful motion inside the proms!  I don’t think recording in 8 bit hurt this one at all!

Absolutely top shelf animation! My eyes are still dazzled, so much happening in there. Bravo!

That animation is killer, excellent job on it for sure.  

 

And that spot is quite good.
