Re: Sun 27-4-2021
Thanks Ivan. I used a Lunt 60 tilt tuned, a IDS UI-3370CP and a 1.85X barlow. I used also a Baader Halpha 7nm before the blocking filter. Since I am doing this, the pictures are more even.

I have in Madrid a Stelarvue sv 90, triplet fluorite in good state. They were tested one by one by Vic Maris. Are you interested and we swap?

Beautiful shot Eric. Impressive prominences.
Which model of Stellarvue do you have? I have a Stellarvue SV90 triplet fluorite which I don't know if would be ok for a Quark.

Re: Sun 17-12-2020
Thanks to all. Yes, Jochen, it is the tilt-tuned version. The sweet spot covers usually only the half of the sun. I am thinking about getting a pressure tuned one or a back filter.

How is the view through your Solarscope but single, not double stack? Do you think better than my Lunt 60 tilt?
