AR 2832 in CaK.
Trying to get caught up on processing. This was taken 6/11
102 F11 achromat (canadian telescope version) masked to 80 + Lunt 1800 CaK Double stack
Celestron Luminos 2.5x and Basler 155
Processed in AS3, Pixinsight, IMPPG
I really like this scope for Calcium.

Re: AR 2832 in CaK.
Very nice resolution! That's one thing I love about narrowband solar imaging. A quality achromat can hold it's own against an apochromat! Achromats are so much more affordable and underrated these days.

I agree. I really like this cheap achromat for Ha and CaK.DeepSolar64 wrote: ↑Sat Jun 19, 2021 4:45 am Very nice resolution! That's one thing I love about narrowband solar imaging.

Very impressive indeed. Achromats are the way to go with solar.

Re: AR 2832 in CaK.
It would be interesting to see the difference between the 80mm f14 and the 102 f11 performance in CaK.
I’ve just moved from a 60 f10 setup to a Vixen Custom 80M (made in Japan) 80 f11.4 and find the results well worth while. I think any system >f10 is good news for the CaK filter.

I will test it the next time conditions allow (60,80,102)Merlin66 wrote: ↑Sun Jun 20, 2021 11:05 pm It would be interesting to see the difference between the 80mm f14 and the 102 f11 performance in CaK.

I looked pretty hard at the Vixen 80/F11.4 achromat

Re: AR 2832 in CaK.
I had to change the focuser to a 2” to accommodate the CaK filter.
I also added a SW focuser motor
