April, 20 Ca K images with Barr + Alluxa stack and TOA 150
Hello,
Yesterday, I was blessed by spells of good seeing thank to windy conditions. The Barr + Alluxa stack is definitely a killer in Ca K.
The ASI 1600 is another killer for Ca K FD images:

The view of AR2816 was great:

Unfortunatly, seeing got worse when I went to AR2817. Sill the view of the flare and some fibrils was great :

Clear skies !

Wonderful!
Call me Geoff.
I do what I do because I want to, and because I can....
Doesn't mean I know what I'm doing, though!

Spectacular images, Christian!
The high resolution results are amazing.
Are you doing your imaging at Pic du Midi?
Cheers.

Re: April, 20 Ca K images with Barr + Alluxa stack and TOA 150
Yup! That works
Is that 0.8ms exposure time running on minimum gain with the ASI?
*edit - ignore me - can see the gain values on the image footer*

Re: April, 20 Ca K images with Barr + Alluxa stack and TOA 150
Thanks to all !
Peter, the images are taken from my garden. This summer, I'll go to St Véran.
Leo, I use Baader FFC at about 3.2x. Maybe Baader TZ-3 could be a good idea too. I'll see if I can get one for a test.

You should give Freds 2.79x telecentric a try at CaK, I find it a brilliant piece of glass down in the blue. I'd be interested to see how you got on with it, and how it compares to the FFC.
