Here's my version of the azimuth setting circle. It's not as professional looking as the other versions posted here but a much more simple setup and just as functional. It allows easy adjustment of the dial once aligned on an object. I had Staples print out/laminate the dial then attached it to foamboard (the hobby store had foamboard with its own adhesive which made the process very easy). Staples cost $6.00 and the foamboard was $6.00.
I borrowed this version from the man I bought my 8" dob from back in 1992. He had installed the same design on that scope.
I'm posting several pictures to show how it goes together. For the altitude reading I'm using the Craftsman digital level (inclinometer - $30.00).
Thanks again to all on this forum for their help with special gratitude to Rod (rnabholz) and Carol (csa/montana) for their extended help.

Tom,
You are welcome - glad to help.
Nice install on your scope, looks like an easy job, and one that is easily reversible without damage to the original finish. Well done.

I went thru the whole thread, I thought someone had posted it for the 10", but alas, I didn't find anything.

10" Dob w/ a 22" base - 19" pdf file scaled to 115% gives you a 22" printout. It's somewhere around pages 5 or 6.

Tom-
Looks good, and easy!
So I take it the dial stays fixed in the center, and the base rotates around it? Is it easy to read from the eyepiece, or do you have to contort around to see where you are at?

19" pdf scaled to 115% - What is the method for this? Printer settings, set to free scale, and up the percentage?

Brad,
The dial stays fixed to the ground board bolt and the box spins around it (as you said).
It is not readable from the eyepiece - that is a definite drawback to this design. Looking at the picture, the focuser is on the left side so I set my "0" alignment at the left back corner. So it's just a step or two back and forth. I'm still playing with options, I may try using the front left corner. Carol and Rod's setup is definitely more user-friendly. I'm real okay with mine because at this time I'm using a laptop computer which is set up a few steps away from the scope. I have to walk to it to get coordinates so as I walk back to the scope I stop at the back to set the azimuth first then the altitude. I'm in the market for a PDA and will Velcro it to the scope next to the inclinometer. At that point I may wish I had a different set up but I'll deal with that if/when it happens.

MM,
In my case, I just took the pdf file to Staples on a flash drive. They had a chart to figure out exactly the percentage based on the size you want. I needed 17.25" and it came out exactly that. The equation that Sader used is the same used at Staples only they have it printed out on a chart. That was my experience.

I just did mine at Kinko's tonight - $14. You take the size you need and divide it by the 19" drawing/pdf file that is listed in this thread, that gives you your factor scale.
Example:
22" base (10" dob) needed
19" pdf file drawing
22/19 = 1.158 or 115.8% scaled up
17-1/4" base
19" pdf drawing
17.25/19 = 0.908 or a scaled down facor of 90.8%
You can go into setup in the printer screen and usually tell it to scale up or down a drawing. I wanted the clean look and had mine plotted out at Kinko's, I then cut it out there and had them laminate it. Hopefully I'll have it together in a few weeks.

Another satisfied Wixey Angle Gauge customer  , seen here on my Z10.
I originally ordered from Wixey, but they sent out an email saying it was out of stock until early May  . I couldn't wait that long, so I ordered it from Woodcraft (had to pay shipping  ) and got it today.
I ran a couple tests this evening before the clouds rolled in. Used some easy to find targets to check - Moon, Venus, Saturn and the beehive cluster. Every one of them was right where Stellarium and the Wixey said they would be. Now for the next challenge - the dreaded azimuth scale!

Hey Dave what did you use to mount your gauge to the Z10? Let us know when you do your azimuth scale, it looks a little tricky with the Z10 base.

That's the beauty of the Wixey gauge - it's got 3 magnets on the bottom of it so it just sticks to the Z10 tube. My only wish for this gauge would be some form of backlight.
I've been pondering the azimuth scale too. I keep going back and forth between the way Carol did it (top side of the bottom base board) or the way some others have done with attaching it to the ground board and notching the bottom base board.
Does anyone think either approach is better than the other?

Dave: I think it looks better to notch the top board; I had no way of doing that, so I took the easy way.
Either way gets the same result; Satisfaction! I like the link that the poster added a tiny red light to view at the notch.
Thanks for posting! Let us know how it goes.
