Hi,
I'm selling a William Optics acrylic Bahtinov mask for scopes from 75mm-110mm. I used it on my Esprit 100 and it fits perfectly.
The reason I'm selling is I know have an auto-focuser.
These masks are better than the normal black plastic ones as the light transmission is higher (92%) and the diffraction spikes are bigger and much clearer allowing better focusing.

Sells for USD43 (approx. AUD55). I'm selling it for
$30 + $5pp
Please PM if interested.
