~100mm long focal length lens

[ZeroID]

I have the makings of a refractor sitting around at home, focusser, OTA etc and would like to play with a long focal length lens refractor, f12-f20 somewhere. It is just an experimental idea on a minimal budget. I was wondering if anyone has an old 100mm lens in the bottom of the collection of bits they would let go at a reasonable cost. I could get something from Surplus Shed maybe but it's not a major project justifying that kind of spend.
If you have anything old, missing coatings, chipped edge or whatever let me know and we'll see if we can come up with a deal.

Cheers :thumbsup:
