 I you would be interested in buying the tracker as a printed kit, head over to [this site](https://openastrotech.com/products/)
 
-## What parts to print:
-**For latitude specific parts:**
-All parts needed once, except:
- - part 05, needed 4 times
- - 20degree has its own version of part 01a, dont use the one from all lat.
+##
 
-**For all latitudes:**
-All parts needed once, except:
- -  part 12, twice
- - part 15, twice
+For instructions, please see [this](https://www.instructables.com/id/OpenAstroTracker-a-DSLR-Tracking-GoTo-Mount-for-As/) Instructable

-The different versions for latitudes work in a +/- 5° degree range. For the southern hemisphere check the first tab of the arduino code and flip the wiring for the RA stepper. Polar alignment will be much harder. 
-Also check out the first add-on, the [OpenAstroGuider](https://github.com/OpenAstroTech/OpenAstroGuider)
-
-I strongly suggest starting with part 14, the lens ring. If you cant make it fit, you will not be able to use the mount at this point.

-**How to use the SCAD lens ring generator:**
-
-You will need [OpenSCAD](https://www.openscad.org/downloads.html)
-
-Take a look at an [example for my lens](https://imgur.com/Ql9mAmH).
- 1. Start by roughly estimating the center of gravity of your lens with the camera attached.
- 2. The coupler is going to be 30mm long, so you need measurements of 15mm in either direction from the center of gravity.
- 3. Measure the first diameter. This is 67mm for me, so i put that into Diam1.
- 4. The next diameter for my lens is the edge of the focus ring, so i put 65mm into Diam2.
- 5. The distance between these points is High1; 9,5mm for me. First section done.
- 6. The rest of my lens is flat, so i measure a diameter of 62mm and put it in Diam3 and Diam4.
- 7. Because there are no more diameter change, I put High2 as the rest of the length of the coupler, which is 30mm - 9,5mm = 20,5. I leave the other values at 0.
-
-All High values have to add up to 30mm.
-If your lens is flat, put its diameter into Diam1 & Diam2 and put High1 to 30. Leave the rest at 0.
-I recommend adding 0,5mm or more to the diameters as tolerance and definitely put some isolation tape (or similar) into the coupler to not scratch your lens. Also, **dont screw this too tight!** It will hold fine with loosely tightened screws.
