[Atmos (Colin)]

I am going to start off by saying that it is damaged. I think it happened within days of getting it over a year ago, I was playing with the helical focuser, unscrewed the end part wondering whether it had the same thread size as my ASI120-MM (which it doesn't btw) and the whole focuser tube fell into the scope and bashed the front lens.

Although there are no marks or scratches I am pretty sure it knocked it out of collimation. For the last year or so I have been curious as to whether the stars in the camera have been caused by mis collimation or from the CCD not being orthogonal. Last night for the first time I put an eye piece into it and it appears to be the collimation.

It has worked very well for me as a guide scope for over a year, only selling as I no longer need it (new mount which has a permanent cloud over it). PHD has never had an issue guiding with it so it does work as advertised (guide scope, not for visual).

I don't really know how to price it, so, make me an offer.
