Another M31...

Postby Rkonrad » Thu Nov 30, 2017 10:20 pm

This is just a repeat of an image - and the only image I've taken under relatively dark skies:(
I'm better at processing now so this would be an update.

Taken with a unmodified Canon 600D and Tamron 70-300 lens at 300mm. F/8, 400 iso. 15x225 sec lights (56 min total) including all calibration frames. My lens doesn't behave very well with the stars wide open at f/5.6 so I had to stop down. I've spent quite a lot of time processing this to get around a lot of issues including streaking, walking noise and just general low exposure. So I feel I've learned a lot about startools though it would be nice some day to just get good data ;) Stars are a little so so, so don't look too closely.

I'd use the option in Color to change green to yellow as there is a green cast to the image.
