Sol - First Light with SM40, ED80, B1200 and DMK41

[sheeny (Al)]

Finally!

Clear skies this arvo, but it was very late in the day, so not ideal conditions seeing-wise. This is a mosaic of 2 avis, I can't get a whole disc on the DMK41 with the ED80. I think there's some artifacts from the wavelets in Registax 5 that have shown up in the photomerge, so I'll probably do a reprocess, maybe with avistack.

Technical gremlins are playing with me as well... I got a blue screen of death from the DMK41 driver or something similar... more problems to solve. I think I'm the original bug magnet.

Great image scale, Al. There are vertical lines throughout it though..

Nice work, i'm hoping to try the PST tomorrow!

Jeez Al dont be so hard on yourself look at what yuve got
Many filaments
Those new Active regions - '54 and '55
a nice even field with good limb darkening

Some other obs
-I get those lines too sometimes, Im leaning twrds bad seeing artefacts but sometimes its due to the optimize phase of Regi - try going straight to stack
-Try to get your orientation right. Check the sun icon here for sunspots or somewhere like spaceweather. Rotate yur cam til the dec is vertical and the RA is horizontal
-Dont be afraid to crank the wavelets up - i use gaussian numbers 234. If its too noisey go to PS duplicate the background layer use filter-noise-despeckle and adjust layer opacity till u get the right balance.

Well done, these types of images are perfect for keeping a "Solar Diary" of how the Sun progresses thro its cycle.

Yep. That's the artifacts I was talking about.

Thanks for the tips Dave!
