I have an Alter D6 German equatorial mount with AWR Go-To precision drives which is less than a year old.
It's in perfect condition and ready for serious observing/imaging.
Very low periodic error - around +/- 6" - and also has PEC to reduce this further.
Very stable and well built - massive stainless steel tripod - gears lapped at factory for maximum smoothness. I have managed to go unguided for as long as 4min at around 1.75px/" with my CCD.
Mount has polar scope with reticule for easy alignment also comes with 2 counterweights and two counterweight bars to mount up to 35kgs (photographic) on it (40kgs visual). I also have two homemade aluminium dovetails to mount on the DEC head that I could sell separately or include if price is right.
The AWR drives turn the mount into a Go-To electronic mount. They are silent when tracking and produce extremely accurate Go-Tos (<3 arcminutes) when properly polar aligned. Totally PC compatible - I use with MaxIm DL/CCD and AstroArt w/o problems.
More pictures available on request and link to my equipment page for specs of mount therein.
Reason for sale is upgrade to a bigger monster!
Price new would be in excess of £3,600 - selling for £3,000 or make a reasonable offer.
Thanks for looking and clear skies for 2005!
