A-Ps imported guidscope has a full 80mm f11 (3.1" aperture). The guidescope includes an achromatic doublet lens coupled with a smooth 1.25" helical rack and pinion focuser having a full 5.5" of travel and locking screw. Dewshield, lenscap and 1.25" diagonal(Celestron or equivalent) are included. Two half-inch wide aluminum bands are attached to the optical tube to protect the finish from marring. Their position is adjustable on the tube. Included are the 4.4" I.D. guidescope rings which mount onto these aluminum bands. The three alignment thumbscrews are adjusted to position the scope. The guide rings (Losmandy) attach to any standard dovetail plate designed for that purpose.
List for this combination is $610 shiped from A-P. My original sale fell through, and I am reducing my asking price to $450 shipped to your CONUS (HI and AK extra) location.
If you are into astrophotography, and looking for a good guide scope with accessories, this is for you.
