Guest xanthic Posted July 19, 2013 Share Posted July 19, 2013 (edited) Taken with my Canon 7D at prime on SW150 newt with Baader Solar filter, 5 subs stacked. Starting to get the hang of stacking in Linux. Command line tool not pretty... Tweaked in DarkTable.

Guest dawson Posted July 19, 2013 Share Posted July 19, 2013 Nice. You are determined to use that mount till the legs drops off See if you can get a series of solar images and watch the sun spots rotating. Excellent work. JD Link to comment Share on other sites More sharing options...

Guest xanthic Posted July 20, 2013 Share Posted July 20, 2013 Cheers I should have pointed out that the linked image is better. Any idea what the brighter areas on the limbs are? Link to comment Share on other sites More sharing options...
Guest dawson Posted July 20, 2013 Share Posted July 20, 2013 My attempts at solar with Baader film showed those paler patches too. Looking at images of the sun with a hydrogen alpha filter, it seems there are paler patches there too, presumabely hotter areas. I've assumed the ones we see are these, and they are just more noticeable in the limbs where the image is overall a bit darker so there is more contrast: http://m.flickr.com/#/photos/74075989@N00/7406968902/ Link to comment Share on other sites More sharing options...
