M13 and NGC 6207

[Dan_Paris]

  Hi everyone,

on the other side of the channel also nights are becoming very short so for once I chose a bright target...  The globular cluster M13 does not need introduction, I put if off-center in order to get the small galaxy NGC 6207 in the frame.

For those that think that I should have rotated the focuser: I agree but with an f/4 Newtonian it is dangerous to do so...

 

Thanks for looking,

 

Dan
