I could not resist this B&L 4000 when I saw it on an auction site. The forums suggest it may not be a classic... Bausch & Lomb didn't make astro scopes for long after this model and it's big brother had retailed in the mid 1980s. Is mine a hidden gem, as good as an old Celestron C5 or is it a poor performer as pronounced online?
In this review I see what was supplied in the box labelled "Bausch and Lomb Criterion 4000 Telescope System", and try out the scope for some birding in Cornwall and over a few nights for astro.
Any owners who can clarify if the "No.2" reducer is 0.5x or some less reduction, please let me know in the comments. It definitely reduces, but I'm not certain how much.
