Laboratorium Solaris: Hello from the other side
AR2297 has gone to the other side but it misses the Earth and send its "Hello!" :)
Coronado PST, 1/2 of Meade 2x Barlow lens, TIS DMK23U274
25% of 1200 frames for "surface";
25% of 600 frames for the loops.
Blend of two images from 2015.03.20, 09:00 and 09:02 GMT+4 taken during test-run preparing for the eclipse shooting.
The sky was hazy but yet better than it had become closer to noon.
To compensate the lack of dark frame I have substracted the modal grey value corresponded to the empty space part of the image. It had reduced grainess somehow, but I did it on stacked images which doesn't feel right. It didn't make a 100% substitute for a dark. Perhaps both approches would work together in concert by removing both camera's dark currents and the contribution of the light scattering in the air(?).
