Antique Scopes

Here are a few pictures of antique telescopes I have come across:

3″ Clarkson refractor, pre-Broadhurst! It’s a terrestrial scope  with no finder and one of those 20cm long rectifying eyepieces to turn the image right way up. Almost mint and an auction bargain at £60. The name  ages it to the 1890s, give or take. ‘Tis a lovely thing! I just need a suitable mount.

Clarkson refractor baffle and slot for focuser rack. Not the tidiest job.

76mm objective lens
The objective lens cell is held in the tube by friction – no threads

3″ Broadhurst Clarkson library telescope on a pillar and claw stand. Around 1920. Black crackle paint finish.

RAS eyepiece. A Huygenian design. Screw thread. Eye relief almost nil!
