Celestron Black Tube c90
Celestron Black Tube c90 with internal helical focuser, older model perhaps 80's or 90's. I've seen some reports that the optics are very good on these.
Has a 0.965" visual back and a 0.965'-to-1.25" diagonal, as well as original finder scope. Original caps also included.
Mirrors look excellent, and the overall condition of the body is excellent too with just a couple of very very minor spots on the anodising.
I bought it second hand some years back with a project in mind that never eventuated. I've never even had it outside yet and need to clear some room.
Asking $150 ONO
Pickup preferred (Padstow, Sydney), but can post at buyers expense.
Thanks for looking
