2nd May Sun-Just

It took two attempts this morning . The skies were blue with a few clouds that looked to be well out of the way when I set up this morning at around 8:30am. How wrong I was. Literally I just got everything ready, setup and focused when a large cloud rolled in front of the Sun, blocking it completely...

Nice images, Rusted. I’ve gone the other way with image capture (Valery’s advice) taking many more frames and stacking a lower percentage. So, typically 6000 frames and 1% stacking for high res work. It really depends on the conditions though and it is a judgement call just exactly how many are capt...

Hi Stephane,

The second one appears to be the best. Proms are visible and there’s a little more detail in the general background chromosphere. Maybe the conditions also changed, which makes objective direct comparisons difficult.
