Orion Illuminated 20mm Cross-hair Eyepiece
As new with box and caps.
Wide 70 degree apparent field and long focal length makes
this great for two/three star goto alignment type scopes.
Has fine focusable cross-hairs.
Typically the red illumination is too bright but you can reduce this way down by putting a loose ball of tissue paper in the illuminator socket.
On the downside edge performance is pretty poor so it's not
going to double as an eyepiece for any serious observing.
Bintel price is $189.
Asking $100 including express registered post in Australia.
PM me.
Thanks,
