    Please note: This set replaces the former set #2458402 for visual and photographic application of the MPCC Mark III. The old set consisted of a multitude of rings – but was not adjustable in optical length such as this V-1 set.

    The idea for this new and much more versatile set was born after we received this detailed question regarding eyepiece adaptation on MPCC, where we recommended our VariLock and focusing eyepiece clamp as best accessories.
