Commodore PET 2001 - Restoration

I picked up this old PET-2001 from a clear-out of old electronic waste a colleague was doing at work. It had been stored in the back of a workshop along with old toner cartridges, ancient CRT monitors, 10base network switches, 286 laptops and more, that were all destined for waste disposal.

Although it looked pretty beat up, it seems to be mainly dirt/sticker residue - the case is in pretty good condition apart from a few minor scuffs on the corners.

Night Sky Images - 18/11/2021

Night Sky Images - 25/10/2021

Clear for most of the night. After successfully using the tracker a week or two earlier I managed to get hold of a remote shutter release cable to allow the tracker to automatically trigger the camera - my previous testing was several manual shutter release image (I don't have an external intervalometer at this point).

I took two different images of the night sky - roughly pointing in the same direct, just at a different elevation; one at tree-top level, the other almost vertically up.

Gear:

  • Canon EOS 200D
  • Tokina AT-X Pro SD 11-16mm f/2.8 (IF) DX
  • Tripod
  • Star Adventurer 2i tracking mount (with shutter release cable)

Weather:

  • Clear (zero cloud for most of the night)

Location:

  • Garden

Software

  • Rawtherapee - RAW file importing, optical correction & image processing
  • ASTAP - Image stacking / general astrophotography toolset
  • GIMP - RAW/TIF to JPEG, cropping
