some good news
- To quick again with infos ? No.
Just as an info. Today the shipment for TMB have been packed and
getting picked up tomorrow with the new real TMB 160F/5.5 MN
Today arrived 15 pc TMB Triplet Fluorite Lens in cell D= 80 mm f=600
mm, but no tube yet ready, if somebody wants to build his own tube,
he is welcome to order only the lens in cell.
- I made one. It turns out that the lens will mount directly onto the
mounting flange of an 80mm Meade model 310. The 310 has a push-pull
cell, holes and thread pitch etc, all compatible with that nice APO
objective! Here's one on Astromart showing the front end of one:
It's surely too much of a coincidence that the two are exactly the
same; maybe they are all patterned off of "vixen" push-pull cells.
The tube diameter is also compatible with the ST80 and ST90; I mention
that because Burgess Optical claims to make a 2" focuser for them ...
as he does for every other scope ever made...
Anyway, I cut my tube down to size; a machine shop made a adapter for
an old 2" AP focuser:
The (serial# 1 !!!) triplet sticks out a bit farther than the old
Meade achro did, but the dew shield and cap still fit on and work.
Apologies for the ugly lettering on the side of the tube; I consider
that my anti-theft device ...

if the same would be true for the 102 achromat I ordered ! Were there
some 4' refractors on the market (hopefully cheap by now) which had a
flange with push/pull screws ?
