I wanted to make it a little easier to hit the angles for framing targets so I'd make a little ruler in Inkscape, print it out and tape it to my focuser. This took a little too long for my taste, so I spent even more time creating a tool to make them in a fraction of the time. I guess you can call this a poor man's manual rotator.
If you would like to add a touch of convenience to your focuser I've uploaded the python script to
Github and there is also a windows executable in the releases. It creates an svg file that if you desire you can further edit in Inkscape. I've had mixed results printing it In anything other than photoshop or Inkscape itself so if your having trouble with a blurry image give that a go. I'll see If I can play around a bit more improve the vector image support.
