This Dob has the 2 inch thick premium mirror, a 2 inch focuser,
flocking in the focusing end, long secondary adjustment screws,
holes drilled through the sonotube near the primary for ventilation,
a fan mounted below the mirror, DSC hardware included (the azmuth
bolt is mounted )and two-4000 step S2 encoders included, the
mirror collimation bolts are stainless (smooth, but holds collimation
well) , telrad with mount, one dust cap.
The optics present a nice image . I observe DSO's and I do not know
Max power or Min resolution.
Everything is in used and not abused condition .Check out the Discovery
website for an image if you wish . They haven't changed.
Thank you for looking! John
