AR12738 - CaH
This spot is becoming popular notwithstanding the recent predictions for a deep and long solar minimum I very much hope to see other spots like this one. Today I succeeded to take one image with my 100ED, again between clouds with some apertures lasting enough to allow some work. Thanks for looking.

Re: AR12738 - CaH
It's nice to see you getting sme good results with this scope, I know bob yoesle gets good images too in the blue end. It's one that's on my potential radar.

Re: AR12738 - CaH
Hello Raf,
The image is quite good. It seems to me that there is a shift in the center wave length ? Or maybe an artefact due to the passing clouds ?

Re: AR12738 - CaH
Thanks, Christian. Yes, I am experimenting with different tunings as this is a useful feature of the Quark, for this image I set the knob at 0 while the best position would be at -5.

Re: AR12738 - CaH
Thanks to all of you.
I imaged at 30 fps (33ms per frame), 150 frames stacked.
it's a good scope indeed, not only for solar. However I think that for calcium imaging a long focus achromat would be even better. I am trying a Tecnosky 102mm f/11, curious to see if can beat the ED.

Re: AR12738 - CaH
33ms, that is surprisingly long. I did not think it was possible to get sharp images with such a long exposure time. Have to try that myself.

Re: AR12738 - CaH
Yes, at max image size it's quite long, usually I try to keep it within 20ms. However the camera works so fine (low noise, no NR, insensitive to dust) that I reluctant to change it. May be next year I will consider to purchase a Basler.
