SA404 is specially designed for the SV41 Mak spotting scope with the M48 Male thread.

With a 1.25inch interface, this adapter supports a 1.25'' telescope eyepiece, so you can make more fun with SV41 in a free manner.

SA404 converts the M48 male thread to M42 male threads, providing an opportunity for associating Canon/Nikon/Sony cameras with the SV41.

SA404 can also work with any other scope as long as with M48 Male Threads.
