Hi Alexandra, Thank you for the explanation and the link to your blog post: now I better understand what to look for! :idea: I'll re-process them without the flat field correction, maybe also lowering to 10% the of stacked frames... monday started with a lot of work :roll: .

Hello, There's a lot of activity today :hamster: : beyond the current ARs, a new sunspot is emerging at the SSW limb and nice proms at the NE and SW limbs. Pleasant imaging session: good transparency and average/decent seeing, stable throughout the morning. Currently processing pictures, will add th...

Rainer, thank you for your help.
I'll set up a shared folder in Dropbox and PM you the link.
In the folder I'll include also the relevant acquisition settings.

Daystar Quark - Help in determining "on band" operation

Hello, As suggested by a number of members of the forum, today I invested 3.5 hours to test almost all the settings of the adjustment knob of my Daystar quark. All the images were obtained by stacking 25% of the best shots in a 1k frame .ser file; exposure 10 ms, focus unchanged, took a flat field f...

Re: 18 Nov 2020 AR2783 and prominence

Hi Alexandra, Thank you for your suggestions. I noticed that below a certain amount of gain I was losing details (or dynamic resolution), even if by increasing the exposure the hystogram was similar. Time for more experiments :) Actually I never touched the gamma slider during acquisition: I was und...

Re: 19 Nov 2020 AR2783 in Ha and Continuum

Hi Stu, Since the quark etalon was installed in a "cheap" Solar Scout scope it may have a broader bandwidth than the ones sold as standalone units. I still haven't figured out whether my quark unit is broadband or off-band: I find the most detail when setting the adjustment 2-3 clicks CCW and that w...

Re: Solar Scout SS60 Etalon on 80ED scope: first light

Hi Rod, I bought my unit 2nd hand so I have no experience with Daystar's customer support. Agreed, not much QC at all: straight out of the box my unit would come on band almost at the blue end of the tuning region... upon disassembly, I found two major dings on the mating surfaces (the black anodizi...
