Well it's worked already! I looked at the list and was pleased to see objects I know I am likely to be able to see with my 6" Reflector. I've just printed the list, keen to meet the observational challenges.
I think a list of challenges for different 'scopes is a good idea also.
But thanks again for including the 'baby' scopes

It's surprising how much you can see with them, especially in dark skies.
