Sorry I don't have the original 25mm eyepiece, given that to a newbie a while back, but I will include a Bintel 12mm Plossl in excellent condition.

Also will include a Focus Mask
And the 12volt cigarette lighter cord and plug.

Cost $899 from Andrews on 20/2/2010. (not including the mask, cord, and eyepiece) - receipt available if required.

Look, its had very little use, but its 9 years old.
I planned to use this for astrophotography in the future.
Never got around to it. Been exclusively visual with my Dobs since then.

I will sell for $400 PICK UP (NSW Central Coast) or PLUS Postage
or offer more if you like.
