I will be taking delivery of an AP1200Gto within a month and am putting my AP1200 QMD “push to” mount up for sale for $5900. I prefer to sell to someone who can pick it up. I live 40 miles west of Chicago. I will not sell the QMD until the new mount arrives.
There are two types of setting circles on my mount: Mechanical and digital. The mechanical get you to within about 30 arc minutes of your target. The digital setting circles work in concert with the installed 4000 tic encoders, MicroGuider 5 computer interface (a/k/a “B-box”) and Earth Centered Universe (ECU) software, all of which come with the mount. The Sky and other planetarium software can also be used. The digital setting circles get you to within about 8 arc minutes of your target.
In use, you align on one or two stars, then choose your target and (gently) push the scope in RA and Dec until the target is centered according to the ECU display. ECU displays both analog moving target circles and digital RA/Dec error signals that guide you to your target. The control paddle can be used to slew the scope the last few arc minutes to the target at 16x sidereal rate.
The scope was overhauled by AstroPhysics on 6/20/03 against work order No. 19279 to fix damage incurred in shipping. It was tested under the stars by Roland and pronounced fit.
Tracking with PEM trained and running is good. I seldom autoguide, as I usually expose for 4 to 6 minutes unguided at 530 mm. See the unguided image below. The autoguide functions do work well should you choose to autoguide.
Comes with 24-inch long AP scope mounting plate, mount base plate, 18 pound AP counter weight, control paddle, ECU CD and manual, MG5 and associated cables.
Please contact me regarding inspecting and test driving the mount if you are interested in an on-site pre-purchase inspection.
Thank you for looking and clear skies,
