[NOT REQUIRED] SW 120/ 1000 achromat

[Merlin66 (Ken)]

I hope someone can help me….
I’m looking for a 120mm aperture long focus achromat (not ED).
Needed for a spectroheliograph project.
Let me know if you have something.
Thanks.

Hi
nearest I have is an SV48 (svbony) 90mm achromat.

Is there anyone with a clean SW 120/1000 achromat excess to their requirements???
Shipping to St Leonards, Vic 3223 - I pay all costs.

Hi Ken,
There's a 150mm f8 achromat in the classifieds that may suit.

Yeah, saw that, I had one previously - too big, too heavy for the SHG application.
I think a 120mm would be close to the sweet spot.

Still looking for a 120mm refractor. Non ED is OK
(I thought I had found one but it fell through…..)
