Been doing a bit of horse-trading with another IIS member, and have a bit of filter stuff to sell. I'll have some N/B and LRGB filters, plus a manual CFW up soon.
Borg filter drawer and slides. Handy, lightweight, and unobtrusive.
Borg Drawer unit #7519. This is the "holder" and is complete with one filter slide that accepts a 2" filter (48mm) or a 52mm filter. The unit as it comes has an M57 male and female thread front and rear, so will attach directly to the Borg scopes. Boxed.
Borg adaptor #7528. This screws directly to the drawer unit, and then provides a female T thread. This makes it female M57 on one side, and female M42 on the other. Boxed.
Borg filter holder #7518. Additional filter holder/slide, to fit the filter drawer. Boxed.
Borg adaptor, I think #7523. This has a male t thread on one side, and M57 female on the other. It is without box, and has been "spun" very gently to reduce the M57 side "depth", and also the knurling slightly, hence the writing not being visible.
AU$130 posted, the lot. Try the prices at Hutech, you'll find this quite cheap compared to new.
Via PM please.
