Tiny 52mm Filter Adapter for Svbony SV535 (M52x0.75)

This tiny adapter slides onto the smooth moving front section of the Svbony SV535 lens and adds a standard 52 mm filter thread (M52x0.75), allowing the use of common photographic filters. The design is intentionally low-profile and lightweight, adding minimal length to the optical path — which is especially useful for astrophotography setups. The outer ring diameter was sized so a Bahtinov focusing mask can be easily installed and removed without interference. It was designed to fit the Bahtinov mask model that I already use ( https://www.thingiverse.com/thing:7317337 ) A simple and practical accessory for anyone using the SV535 for astrophotography.
