All depends whether the spot was emerging or decaying when the picture was taken. Laszlo, can you elaborate on the time and date of recording please.

Re: Calcium prom attempts!
that the proms were stronger with 40mm although perhaps at the expense of the disc being less sharp with the increased exposure. Does that happen or did it just seem to happen and it was coincidence with a change in seeing. With reduced aperture (and longer focal ratio) the bandpass of the filter w...

Nice results Warren. I must be honest over the years I have completely unfavoufred and no longer use etalons in these cells that friction fit on dew shields, exactly for what you found, they sag and cause uneven illumination and tuning. My front mounted etalons only screw directly onto otas, and, th...

Nice shots Lazslo. You are lucky to have such seeing conditions.
To answer your question, what do solar field strength charts show for the day of capture?

Re: 393.3nm K-Line imaging session w/stop down mask.
Now only if I can find a large plastic jar lid that will fit the dew shade on the C102. 66mm would be an improvement over 40mm. Cutting out a cardboard ring will be easier. True. It won’t look as good or last as long but it will work. Just pop it in the dew shield, no need for tape or anything. Tak...

Calcium Sunday 21st April
Sunday was forecast to be cloudy, but by some miracle by 11am it cleared up partially. A decent wind from the northeast with scudding clouds meant the seeing was never going to be great, but transparency was very good and so I decided to dip into the blue end again. Still tweaking the CaK setup, and...

Yes, the C102 will do well, even better if you stop it down to 66mmDeepSolar64 wrote: ↑Mon Apr 22, 2024 1:22 am My C102 is an F10 so it may actually do quite well for K-Line imaging. I also have a 60mm F12 but it has an 0.965 focuser. The Antlia wedge will not fit it. That would be even better if it would.
