I had not seen this thread before.
Carol, really nice job on that AZ circle.
I know this is an old thread, but it is worth bringing back so others can see what you did.
I am interested to know if you still use this method to find things or have you moved to a different approach.
Ed, things have changed a LOT since the beginning of this thread, and for the BETTER as far as using these circles and inclinometers are concerned.
Current phone apps make getting alt-az coordinates of objects a breeze.
New inclinometers include the un-illuminated tiltable displays of the Wixey Model WR365. This one also has one scale that can be zeroed, and one that is fixed, and is easily accurate within 0.1 degrees.
I recommend you read just the last four or five pages to get up to date. Several of us have drawn circles optimized for this use and have shared the files on these pages.
All my future scopes will have these.
