I recently picked up an early Unitron model 150 - likely built in the late 50's (block lettering) - and I have two questions regarding it. I would include photos but I'm unable to do so
at this time.....
A. The 10x42 viewfinder has what appears to be flat latex "china-white" wall paint spattered
onto sections of its (now after 60+ years, Ivory colored) tube. How might that wall paint
be safely removed without damaging the underlying original paint?
B. Its rack and pinion focuser is truly massive - with machined knobs - but I'm not sure it
is a true Super Focuser. For starters, it has no focusing scale. Its current adapters and
extension tubes only accommodate .965" and 1-1/4" accessories. That alone would
seem to imply a Deluxe Focuser. However, my 6" Fecker is equipped with an early (non-
focusing scale) unbranded Super Focuser. It has an extension tube and adapter that can
thread directly to the 150's R&P main tube, that will in turn directly hold 2" accessories.
So my question(s) are simply this:
Can a Unitron garden-variety Deluxe Focuser be made to do that? Or do I have an older
version of a Super Focuser that may be adaptable but was never specifically designed to
accommodate 2" components?
Folks, I know very little about Unitrons other than salivating about the larger ones for the past
half-century. Any enlightenment you could provide me here would be MUCH appreciated!
