Hi,
My improvements on M104 (i include the first one I did...poorly)
registaxed 2x 151 sec exposures, ISO 1600, EOS 20Da, unguided. That's the one without label on the pic, I also processed another single exposure included here too.
I'd spent a bit of time trial and error style working on drift alignment for the first time...
Despite the Moon at about 80%, there wasnt a hint of a breeze so i couldnt resist a trial.
not perfect but as StrongmanMike would say, it's an improvement on the previous one.
Now I'm off to work on 3.5 hours of sleep
(and running late already...)
