Hi everyone, thought I'd start a second thread on something that may be of interest.
On ebay, there are some large refractors lenses(some with short F ratios, some with medium - longer ratios)for sale by''Telescope Diy''
They don't specify much on optical parameters/specifications, but I was wondering if anyone has heard, good or bad, if these lenses are any good?
They're cheap compared to the big optical companies/brands, but hey, could be a bargain in the making???
