It was sunny here for most of the day (will wonders never cease?) , but the seeing was none too good. In fact, after I shot a few videos with the SolarMax, I decided to put the Baader Digital Solar Filter (OD 3.8) on the Celestron 1100 Edge HD and check things out. It was a disaster and a half. I've never seen anything like it! The histogram was doing a horizontal dance ... in both SharpCap and Firecapture ... and on my computer screen, the image from the ASI 183 was jumping back and forth between a dark, barely recognizable granulation and a white overexposed image ... with a few vertically scrolling horizontal bars thrown in for good measure! Guess I won't be trying that again soon.

 

Anyway, the SolarMax gave me a nice prom and a couple of solar disk images ... plain though they might be. I was wondering at the time if Warren were shooting the prom because it was changing rapidly. At first when I saw it, there was only one arch, but I could faintly see a pillar dropping down to split it in two. By the time I got this there were three distinct divisions.

Nice catch!  It was sunny here but with gusts to 40mph I didn’t bother to setup!

Nice catch James, I was watching that prom today and the faint large field of proms opposite it on the other limb.

 

Very best,
