I use Sky Atlas 2000.0 at the scope. I removed the spiral binding and only take the ones I need for that session.

I do occasionally use Uranometria 2000 depending on how deep I am going.

I have a Skywatcher 130m on an az gti mount and have a relatively restricted view of the sky.  If I want to look at a certain part of the sky be it North or South  I have to reposition the scope as I have trees and houses around me.

I'd like to push the scope and look for stuff I would not normally go for iike hard to separate doubles and the like.

Some suggestions please.

I am not sure if this is what  Fraunhoffer was referring too.

Stephan.

Looks like you had a good night of observing. Read with interest the report  on IC 4593 and NGC 6210. I am a fan of PNe.

I use the Farpoint 650nm laser collimator. Easy to use and accurate
