Description

Tasting like summer

One of the summer clasics, the trifid nebula captured with the altair astro 8" f/4 imaging newtonian, equiped with a Baader MPCC, Canon 350D TEC cooled, EQ 6 mount, stack of 11x 5 min. @ 400 ISO. I didn´t use any dark frames, I'm finding that with the cooled DSLR they are not necessary, I used 40 bias and 40 offsets to calibrate and that's it.

I had to crop heavilly this one, a mix of imperfect polar alignment and some focuser flexure trashed the corners...:/ But still a good result I think
