Help needed with Azimuth Circles

Hi Guys

There is a WSAAG observing night coming up on Sat 28 June at Linden, and my wife has said she would like to come along a take a look

So I have started making up a list of things to try to find in an Excel file - going well so far, but then I realised that I do not know exactly how I am supposed to read my Azimuth circles (from the article by Denis) - haven't been out observing since I made them

lets say I have the following info:
Name: Lagoon Nebula
Mag: 5
RA/DE: 18h4h45s/-24°15'40"
Az/Alt: +92°40'44"/+43°18'07"
(been playing in Stellarium i have )

Any advice on how I am supposed to read them - I'm guessing I use the Az/Alt details above, and I am guessing I should have 0 (zero) on my circles pointing North, but is that magnetic, true or polar (why isn't north just north)

Also, any suggestion for other objest I can try to find would be nice, my Dob can apparently see thigns upo to about mag 14 or so, so I already have Pluto on my list (14.76)

I've attached a pic of my scope with it's circles and protractor - yes it is on my balcony, been viewing Saturn every night this week just before and after dinner time - brilliant considering the light polllution around here, actually saw shadows on the rings last night

thanks in advance

ps, anyone else going to WSAAG night at Linden on Saturday?
