A Big Sun

Hi all -

This sun portrait was stitched together from 16 single webcam frames taken in very turbulent air yesterday. I used my 5" refractor and 90mm coronado filter at 1 meter focal length.

If you are attending NEAF next weekend, please come by the solar star party and say hello!

happy sunday -
Alan

THEN IT'S TRUE WHAT THEY SAY: BIG IS BEAUTIFUL Nice detailed full disk Alan. When the seeing doesn't cooperate that's about the only thing one can go for

It must have taken forever to stitch 16 webcam images Alan.
However, even we had a little truce from rain yesterday, but the seeing was so bad that the image in H-alpha looked liked a white light image, i.e. there were no details whatsoever and you could just see the dark spots of the active areas. I recorded some sequences, but they are definitely trash can material even the F8 ones at only 820mm focal length were so bad to be a waste of time to process >

Tomorrow the weather should clear up, but I truly hope that the seeing won't be as bad asit was yesterday otherwise the frustration will be double. Tuesday and wednesday are foreacsted as good days, but, needless to say, I gotta work :C !!!!

Ciao Alan

Thanks Luca and Dennis.

Luca - it didn't take too long to do because I just scanned the video and selected one sharp frame to paste into Photoshop. The signal is pretty good in a single frame, but the brightness varies quite a bit - adjusting the image to hide the seams is the hardest part (and it could have used a little more work!)

cheers-
Alan

Nice shot Alan - just the way it looked in the eyepiece - WOW!
