WoW Valery. That is really good for the seeing to not be that good. What type of telescope is the 12"?
Re-read my post. You can see that this is a Meade 12" F/10 ACF.

AR12770 in H-a August 10 2020 with 305mm telescope and QUARK.

Hi all, Here is the image of the AR12770 in H-a I managed to take yesterday morning. A light bridge is seen in it's glory. Seeing was really horrible all the morning session and only one barely acceptable image in the result of 1 hour session. Right Click on the image to open it in a separate window...

Re: CAK and HA images with ARIES D-ERF + C11

a 1A Alluxa Calcium filter Do you have a test graph of the transmission curve for your filter? The graph of the very same filter I have saw showed about 2A FWHM. And in this case this single cavity filter (and it is indeed a single cavity - as seen from the graph) is not as good as, for example, a ...

Re: CAK and HA images with ARIES D-ERF + C11

The sky is usually clear from 8 to 9 am when the Sun is clearing this tree. After 9am, after the Sun has cleared the tree, clouds will usually cover the sky. The Sun will rise slightly to the right of the tree in a months' time for me :) Alfred, it seems your observing conditions are not that hopel...

Re: August 3, 2020: Calcium Trio

Hi Peter, Very impressive results. Yes, I still hope that with a narrower slit you will be able to detect some filamentary-like structures which makes 8542.1A images as a mixture of Ca and Ha images.

Nice to see the sun with higher activity.

Any chance you will image the sun at Ca II I 8542,1A with your spectroheliograph?

Re: Finally Some Sun - 30th July

Hi Mark,

Great session after a long wait. What is a strange aperture 118mm ? Is it your 127mm refractor?

Hi Stu,

Nice images, especially in CaK at a high res.

BTW Why don't you use a big 10" cannon?

Thanks for the info, Rainer.

I hope to be in time with a new 300mm solar telescope. Only a few steps in DERF cell finishing remains.

Re: Sunny Sunday morning 19th July '20

Very nice session, Stu!

But the CaK with 5x barlow is something special. Just need to be catched through your 10" instrument for a total perfection.

Re: 2020.06.09 H-a Full Disk and AR12765 closeup with C11

The resolution is really high, Vlad. However it seems the Quark was not tuned exactly at the H-a core - photosphereic granulation is easy seen.

Am I correct guessing the F/D was F/42 at the Quark etalon?
