Feb 10, 2013: Sun in white light; first try with DSLR and APT

[michael.h.f.wilkinson]

Had my first go with APT and my EOS 450D behind my APM 80mm F/6, using Herschel wedge, ND3 filter, Baader Solar Continuum filter, TeleVue 2.5x PowerMate. Exposures at 400 ISO, 1/160s, Raw images cropped, centred, and converted to 16bit TIFF in PIPP, stacked 27 exposures out of 61 with Registax 5. Downscaled by a factor of 2. Not bad for a first try but I need to get rid of the Baader filter and shorten exposure time that way.

Lovely, nice and crisp, well done

Nice detail on the big sun spot group Michael. Glad you had some clear skies.

Thanks, guys. The sun was quite low in the sky by the time I managed to get it. The view through the Herschel wedge using an XW10 was nice and sharp. I do indeed think it is sharper than the image with the C8 and Thousand Oaks filter. I might do a side by side comparison.

Good image with fine detail and focus. If you get the exposure down and stack a few more frames the granulation should come out in the processing.

Excellent detail, well done

Nice image Michael. At least someone is getting to see the Sun!
