Quote:Quote:What should be the proper orientation of a degree circle markings should I use, CCW or CW on top of the box board? Carol, in your attached photo, it appears that you have it both ways. Thanks. shien If you mount the degree circles on the bottom fixed base, then the numbers should increase clockwise. If you mount them on the top board, then the numbers are counter-clockwise, and the pointer would be attached to the bottom base.

Quote:I took Gordon's 24" original (for 12" scopes), and scaled it to 22" for 10" scopes. While I was at it, I went ahead and added intermediate numbers, every 5 degrees.Please note this one is clockwise-only, so wouldn't work attached to the TOP of the base--it should be attached to the BOTTOM part.I printed it today, and it looks perfect for the Zhumell 10" scope. The PDF file itself is actually 23" x 23" (because of a slim margin around the circle). When they print, just make sure they print it at 100% size, and don't do a "shrink to page size" (took two printings for my local OfficeMAX to get it right).I'll post pics when I get it installed. Thanks for the fabulous ideas, everyone!

You will find that being close to level improves the accuracy of the Azimuth. Perfect is not required but close is good. If you want to, try setting it up several degrees out of level and using for a night.
I found out the hard way by forgetting my level one night, so I just set by eye and pointing was poor all night. I keep a spare small level in the vehicle now. Altitude will still be good with the Wixey
ahhhh, the azimuth! i see, said the blind man.
i've got a circle printed out and i'm going to replace the bottom board and put the circle on that. i bought the digital torpedo level at sears. i think i read somewhere in here that placement of the level is key. i would like to put it on the mirror box. i don't think putting it on the struts is going to work as they taper inwards, and it would be a bit tricky, but do-able, to attach it to the secondary cage rings.
i have two extra printouts-- one is a 13.5" diameter, and the other is 19". i love that the guys at work with the giant sized macintosh and illustrator and a hp plotter took three tries to get it right. they are available for free.
