2019-05-12 - Sol in Ha & Time Lapse

[PhotoGav]

I had a bit of a session on Sunday with the active regions (AR 2741 and the fading AR 2740)... A quick disk, that might have been a bit too quick as the illumination seems uneven - I think due to incorrect tuning of the etalon? I then zoomed in a bit to try and get a timelapse of AR 2741. If you look closely you can see a bit of 'squibbling' going on in the area around AR 2741. The majority of the movement is from the seeing - it was very hazy, but that didn't deter me from experimenting a bit! I then had a play with making an animated gif file in PhotoShop rather than my normal approach of making a video - thanks to @Davey-T for the tutorial on how to do it!

Kit: Lunt LS50THa, Chameleon3, 2.5x Powermate for the close ups. Roughly 1000 frames per grab with 15% stacked in AS!3, sharpened and aligned in ImPPG.

Full Disk

 

Time Lapse 1 - 40 minutes elapsed time @ 1 frame every 30 seconds (look around the AR)

Time Lapse 2 - 1 hour and 8 minutes elapsed time @ 1 frame every 30 seconds (look especially to the left of the AR and at the large filament like structure to the right of the AR)

Good job Gav, just got back from a couple of days at dark site, spent most of it fighting with the 10Micron
