Tracker Tester

Ages ago I wrote a simple BBC Basic for Windows program that slowly moves a single, white pixel across a blank computer screen. It uses the resolution, width and distance away of the screen to move the pixel more or less at sidereal rate, allowing it to be used to test tracking in daylight, even indoors!

I did post a link on SGL a couple of times then forgot about it, but I’ve just been asked if it’s OK to share it on a Facebook astronomy page.

The reminder made me think I ought to post the link here:

I’ll try and remember to bring it along to a mid-month meeting to do a demo!
