Canon 58mm to 2 inch astro filter adaptor

thingiverse

To attach a 58mm canon lens to a 2-inch astro-imaging filter such as my Baader UHC-S filter, you'll need an adapter that converts the 48mm thread of the filter to fit onto the lens. This particular adapter has no threads itself, but it snugly accommodates the filter perfectly. To complete this setup, you'll also require the ring.stl file available from adibadro's creation on Thingiverse.
