Re: The Sun - 20th April

Thanks all
Stu - Yes, white light shots done with the Lacerta wedge. Close ups done with the ASI and the full disk with the DSLR. I have both the Lacerta and Lunt 1.25" wedges but cannot see much difference in the results.

The Sun - 21st April

With all the AR activity moving off the disk I thought today's session might be quite short, turned out quite the opposite! Lots of prominence activity to grab instead. Not a whole lot going on in white light but found some nice detail close up. 20190421-10.jpg 20190421-11.jpg 20190421-13.jpg 201904...

The Sun - 20th April

Tougher conditions today, seeing not bad but some high-haze / cirrus which has left my Ca-K FD a little uneven. Still lots to see today with some decent proms to go with the AR and some nice granulation showing in WL. 200419-6.jpg 200419-5.jpg 200419-7.jpg 200419-0.jpg 200419-1.jpg 200419-2.jpg 2004...

The Sun - 19th April

Clear skies today but rough seeing. These are the best of what I got. Some nice proms showing visually in the PST but not a lot showing in Ca-K today.

The Sun - 12th April

Grabbed some data early Friday but had to leave for weekend camping trip before I had chance to process. Some nice seeing early Friday gave me a chance to get some good data. 20190412-9.jpg 20190412-8.jpg 20190412-7.jpg 20190412-0.jpg 20190412-1.jpg 20190412-2.jpg 20190412-3.jpg 20190412-4.jpg 20190...

Great set Mark. Didn't get chance for much more than a quick glance at white light today unfortunately.

Slim pickings today. solr-0.jpg solr-1.jpg solr-2.jpg solr-3.jpg solr-4.jpg Not sure if these qualify as "Polar Faculae". They were in the right place and look roughly the right size. Thoughts? solr-5.jpg Having a bit of a nightmare getting my orientations right at the minute so bare with me!

Re: Finding Scopes That Are Well Corrected For Ca-K Imaging

Thanks Guys @Mark - Had crossed my mind. I was actually considering the upgrade to try and up the quality of my white light images (removing some of the losses caused by chromatic aberration) but do not want to adversely impact my Calcium imaging. @Bart - great thread with some interesting links, th...

The Sun - 23rd Feb 2019

Foggy and cloudy this morning but then the cloudy parted and left us with a sunny afternoon. There were no spots in white light but some faculae on the limb. I also did some polar shots, looking for polar faculae but there was almost no activity at all. There was a nice plage area in Ca-K as well as...

Finding Scopes That Are Well Corrected For Ca-K Imaging

Simple question, when looking at potential new scopes is there a way to tell if it will be sufficiently well corrected for Ca-K imaging? My assumption is the only reliable way to tell is to try it, which is kind of limiting. Thinking of moving from my achro Skywatcher Evostar to something like an F/...
