As soon as the sun has cleared the rooftops I will be imaging JAmes, and, are actually nipping up to the boat later on this afternoon for an hour to take some bits and pieces up. Definitely ...

CaK 10th August

Hi All. We have our 'heatwave' here in the UK at the moment (read it's summer!), and while we have temperatures in the low 30s and cloudless skies all day and night it does mean that there are only really a couple of hours after sunrise for solar before the seeing collapses.

Montana wrote: Wed Aug 10, 2022 6:29 am Very interesting!! the third link shows that h-beta is very similar to the wings of h-alpha (the offband image in h-alpha that they show). So I reckon it's height is between halpha and photosphere.

Re: Solar surface focusing

Hi Dave, welcome to the forum, that;s a great opening image. Regards focusing, depending on when you are observing (first thing in the morning is by far the best) and given you are observing at 180mm aperture you're issue may well be poor seeing conditions. Best advice from me would be to use either...
