So conceptually I am enjoying my new Quark chromosphere and new ZWO ASI174mm. At f27 native there are hints of terrific detail when the seeing permits. Using a focal reducer gives satisfying views of the disk at medium resolution.
Here are links to three videos testing what I perceive as uneven illumination.
The first video is a general tour around the sun. Nice surface and a large flare: https://youtu.be/q6BQptmLMEI
The second video is when I twirl the quark and keep the camera still. Notice the illumination patterns in the background moving: https://youtu.be/vGp-2QrEfVA
The third video is when I twirl the camera and keep the Quark still: https://youtu.be/tTalXaun36E
My question is, should I be happy and try and remove the inconsistencies with flat field or should I exchange for a third quark?

Re: Videos of Quark number two
Let me know if the videos came out ok if you look. In some test equipment the videos are clear, on others poor.

Re: Videos of Quark number two
Looks like that is a much better Quark Jack, difficult to comment on detail as maximum resolution I can get in youtube is 480p.

Re: Videos of Quark number two
Thanks, Mark. I will produce a higher res YouTube video.
Your wisdom is appreciated. Gotta say again, I’m enjoying the new approach for me.

Re: Videos of Quark number two
Hi Jack...
Too bad these was so little detail to see the Quark in action, but I would think that a flat would even the FOV up very nicely.

Re: Videos of Quark number two
Thank you all for your comments. I feel optothen that the quark is ok.

Re: Videos of Quark number two
I've created 1080p videos if you care to look.
https://youtu.be/m4xEocoJW6k Tour the Sun 1080p
https://youtu.be/9O3tt94v7Vo Spin the Camera 1080p
https://youtu.be/wcws4cSwonI Spin the Quark 1080p
The optics train is:
D-ERF
152 mm f6.5
2" diagonal
UVIR CUT filter
Quark Chromosphere
2" Mallincam Focal Reducer (close to camera...no nosepiece so not a full 2x reduction)
ASI174mm
Best,
Jack

Re: Videos of Quark number two
Looks good. You should be able to flat out any banding etc no problem.
