If you don't fancy parting with 60 quid for one of these:

get one of these:

It's wrong M42 thread pitch, but without forcing it still screws on most of the way onto an M42 extender tube.

For my ASI1600 for example, I need one 5mm extender and the 11mm it comes with. That plus the adapter screwed on gets me infinity focus no bother with my DLSR lenses.

Saves you 50 quid, and maybe lets to play with your DSLR lenses without having to justify it's worth it ?
