350D(modded) with ED80; Guided ST80/DBK21
4 x 300secs ISO800
Flats, Darks, Bias.
Stacked DSS, tweaked in PS CS3.'
I'm a little worried that I may have taken bad Bias frames? or used wrong master combine routine? For some reason there seems to be a vertical granulation after processing, also the corner brightness Im not sure if its light pollution, nearby laptop light or error in the stacking process.
Still alot more to learn(though I learnt alot from tonights 6hr session of to do's and not to-do's
).
All comments welcome.
P.S I'm already wanting more aperture
