Wanted: Sky-Watcher 3.6mm Eyepiece

Does anyone have a [u][b]Sky-Watcher 3.6mm[/b][/u] Super MA eyepiece they no longer want?
(yes, I know it's a [i]really unusual[/i] request!)

It's the eyepiece that looks like this:

The problem with these is that there is so little eye relief that you can't actually get your eye to the correct place. And the design doesn't work properly with scopes shorter than about f/12.

If you want to remove the lenses & use the rest as a "collimating cap" on old 35mm film canister with a hole drilled in the base will do just as well. (Nearly as effective as an eyepiece, too!)

I don't like to make disparaging remarks about cheap & nasty kit but that eyepiece really is the pits. The only reason it exists is so that the marketeers could put "x500" on the box. If you really want a usable, cheap, short focus eyepiece look for the Skywatcher 5mm LER.

You mean the Sky-Watcher Skymax 90 Tabletop Telescope can't really do 347x magnification after all?? [b];-)[/b]

Seriously though - it is pretty appalling that an otherwise respectable company like Sky-Watcher advertise a 90mm Mak as being capable of 347x magnification isn't it?

Anyway, regarding that 3.6mm eyepiece, I was just interested in punting £9 or so just to see what it's like, just out of casual interest (after all, sometimes you strike lucky with such experiments).

However, you've satisfied my curiousity, and I won't bother now.


Thanks for your reply.
