M56

Taken with a partly collimated ODK12 and my M25C, on 6.6.15. An exposure of 30 x 60sec without flats or guiding. More work needed on collimating and mirror distance too, but improving well. I'm hoping to get stars to be the size of those seen by my Tak 106 but keep forgetting that the ODK12 has a focal length 4 times that of the Tak. Stacked by sigma averaging in 10s then adding the three averaged sets. I also need to aim more carefully. All done during the collimating process.
