Hello All

M27, the Dumbbell Nebula, as I continue to test for tilt and optimal backfocus for my new CMOS camera.  With the reducer I am testing the field of view is huge so M27 needs to be cropped to be appreciated...

It never ceases to amaze me what you manage to do from Petts Wood.

M27 is excellent, have you got a crop?
Also your Jupiter images are getting better and better.

The world's laziest astroimager.

Roberto

Thank you both.  Carole, Jupiter is getting better because it's much higher  :lol:   I don't have a crop of M27 - do you want me to send you the original file?  It can be downloaded from Astrobin if not.

That's OK Roberto, I already got it from the full file on Astrobin and cropped it. but wasn;t sure whether you would prefer to do that yourself.  I shall be showing the full frame as well.

Great images Roberto love the Jupiter one and I know Dumbbell is a challenging one.
