Here's my first light with this camera.  I was floored by the results.  I started this project with my QHY16200A, and later compared the same optics/exposure w/ the ASI6200MM, and it was a night and day difference.  I also did a quick comparison shot of the Veil nebula with gain=0 vs. gain=100, and saw a really big improvement.

I am thinking of getting an ASI6200mm Pro.

But the earlier thread complaining of banding concerns me.

 

Was this resolved or is it something you have to contend with in processing the images?

I have no banding problems.

I have no banding problems.

I still see the banding, but only in extreme short exposures. Also the banding signal is only 2-3 ADU over the background signal. Hence it vanishes during stacking or longer exposure and only visible when stretching a an image with very low variance in signal. Do not get tempted to create bias or very short flats.

There has a been a lot of tall about the opening size. Is the M68 mounting plate now standard with the latest shipments or is it an extra?

Looking at the ZWO page, it seems M54 is still the standard. It wouldn't only be just the M54 that they'd have to swap out. They'd have to change the M54-M48 extender that comes with it.

 

On a separate topic, anyone has any thoughts of using a Chuwi Larkbox (Celeron J4115) as an acquisition miniPC for the ASI6200MM? It has 6GB RAM and takes M.2 SSD's. Does one need beefier i5-core processors for the ASI6200MM just acquisition & guiding, or would the J4115 do?

This one looks really good to me, and would probably be the one I purchase. Already has a WIFI extender, and is pretty small.

Considering you can get away with a 4GB Raspberry Pi for the ASI6200, I don't think you need something super powerful...just something with lots of storage.

That's my thinking that if a RPi4 can manage the ASI6200, I don't think I'd need beefy PCs. I won't be doing post processing but I'm just not certain if the likes of autofocusing routines would be CPU heavy.

 

Considering these miniPCs are pretty cheap, I guess it's no harm in giving one of these a shot.
