Have for sale a primary and secondary mirror in good condition. Unsure of the focal length but I think its around f5-f6, but cant guarantee it.
I bought from an enthusiast but he was going into a retirement village so had no further use for it.
The larger mirror measures 4.5 inches across and is about 9/16 thick and includes the mirror cell and ring for the other end of the tube.
Have a look at the pictures attached.
I am asking $30 plus post.

I gave the mirrors to the local school to experiment with.
FYI, these appear to be Tasco optics. My 11T main holder/cell is
exactly the same, as is the secondary and spider. The top ring is
slightly different, so it's probably not an 11T (f8), but another Tasco
model from the Japanese era.
