I'll save you my missteps on Quark Testing Rounds 3 and 4...suffice it to say that I processed my tests but I could not make heads nor tails on interpretation with such poor captures...and the light patterns did not seem to change much.
Then I discovered how to let SharpCap trigger capture once seeing reached a threshold...that helped get better videos. Next time I will also tell SharpCap to, "only capture any particular frame when the seeing reaches a certain level".
For this round of tests I also mis-applied a friend's advice and and I took my 152mm and extended my .5 focal reducer to get a very wide FOV, but then I also applied a 95mm mask to increase the focal length. I should have applied the mask only when I was starting without the focal reducer.
Funny enough...I really liked the view!
So I captured 200 frames when the seeing reached a mediocre level and then processed in batch in AS3 identically and then I processed in IMPPG with an identical curve.
I still can't interpret which Quark setting I like best. There is an active region in the center of the FOV.

Re: Quark Testing Round 5
My advice: return this Quark and try to get better one.
I am impressed how the DayStar can sell these crap devices in such a large number.

Re: Quark Testing Round 5
To my eyes negative 1 or zero seem the best, however I agree with Valery, send it back, no good.

Re: Quark Testing Round 5
Tell me what is poor about this. I need to be able to speak intelligently to Daystar/OPT. I certainly don’t get what others seem able to get on both proms And surface at the same time. And others have suggested that the banding will be corrected when I do flat fields (which I am not doing during my tests).
Best,
Jack
Thanks,

Re: Quark Testing Round 5
Jack,
It seems this Quark sample has too much unevenness in bandwidth and transmission. In brighter areas, contrast is significantly worse than in darker areas. Yes, to some extent you can correct changes in brightness, but you cannot correct contrast and detail. In addition, such a Quark will not be pleasant to use visually.

Re: Quark Testing Round 5
You nailed it visually. Visually I have almost no contrast. Nothing but a red field.

Re: Quark Testing Round 5
Yeah, zero / neg 1 looks good to me.
Just bear in mind visually you won't see much, there's nothing to see. Proms and surface at the same time will just come with experience in both capture and processing.
