+Graham Posted July 29, 2013 Share Posted July 29, 2013 After taking on board Steve's advice I have stopped the GT 81 down to about 1 inch in diameter. I then spent the best part of today dodging the rain showers trying to gain a decent focus. After some more advice at lunch time from Steve on using the focusing help software available in Artemis Capture I think I have finally managed to get it pretty close. GT 81. Atik 314 L. Home made Baader filter. 189 subs at 0.001 seconds. Stacked in Maxim. Coloured in PS 6. Link to comment Share on other sites More sharing options...

philjay Posted July 29, 2013 Share Posted July 29, 2013 Much better Graham, faculae and granulation coming through well now. Focusing can be difficult on solar, you should see the fun I have focusing the f15 with the atik in it, the focus wheel is miles away I take it you stopped it down to dim the view with the min atik exposure? I stack an ir, contrast booster and a red filter on the cam nosepiece, this fims the image sufficiently so I can use full apeture and also brings out contrast and detail Link to comment Share on other sites More sharing options...

I stack an ir, contrast booster and a red filter on the cam nosepiece, this fims the image sufficiently so I can use full apeture and also brings out contrast and detail Phil at F15 I can only imagine . Yes stopped it down because I was running minimum exposure but still blowing the center out . I see I am going to have to get myself some filters to progress with this further.
