Non branded short tube wide field achromatic refractor OTA (looks like a Skywatcher or Saxon). All parts are metal, except the focuser knobs.
- Lens diameter 120mm
- Focal length 600mm / f5
- 2” single speed focuser
- 2” to 1.25” adapter with T2 thread.
- Weight is about 3.5 kg
Unfortunately no front lens cap (an empty two litre Greek yoghurt container did the job for me).
Bought this OTA second hand. Previous owner stored it without a dust cap, so the front lens was quite dirty. After careful cleaning I noticed that the top coating layer came off in irregular patterns, see lens pictures. It looks worse than it is and only really visible on bright direct reflections. It didn’t cause any issues while observing stars or planets. Otherwise the lens is in good condition.
Tube has some minor cosmetic signs of wear.
Start test did show slight off axis alignment. As the lens isn’t adjustable I moved the focuser in line with the lens with the help of a laser collimator.
OTA as described above: $179 (plus posting)
