DÖRR

A reflector and a photo adapter

Two unrelated products

The DELTA 1000 reflector and a universal photo adapter share a badge and nothing else. The site treats them separately, because they are compared against entirely different shelves.

The word “universal”

On an adapter shelf, universal is a claim and not a specification. What decides whether the part works is the range of eyepiece diameters it clamps and the phone or camera dimensions it accepts, and the page reports which of those the maker publishes.

The reflector

Aperture and focal length published; the mount, as always at this end, is the part that decides the first night.

Reading a DÖRR page here

Look for a measured range wherever the word universal appears.
