This would be a wonderful set up for someone who would want to do a tandem application with perhaps an H-alpha scope for the upcoming Venus transit. Less than a Month old, I am selling to fund another project otherwise I wouldn't part with it. This is a ALL metal and no plastic "PROFESSIONALLY MODIFIED SUPER MAK". This is 1900mm Focal Length at f/15. A small number of Custom ETX-125 White OTA's were originally designed and built by Meade for a special laser communication application. These OTA's were designed to have the same optical performance as the standard (Blue) version, but with substantially improved opto-mechanical properties compared to the standard off the shelf ETX 125.
Meade Design Improvements:
4 times finer focus resolution than standard ETX-125 telescopes and greater image stability.
Increased baffle size for rejection of off-axis stray light
ADDITIONAL design improvements built into this design by Optical and Mechanical Engineers at Wegat Optical:
Black Anodized Aluminum Adapter that allows for the use of the included 1.25"/2" super smooth rotatable Crayford fine focuser with zero image shift, or other Meade/Celestron Schmidt-Cassegrain telescope accessories.
Larger diameter main telescope focus knob for a more comfortable grip than with a standard ETX-125. This OTA can be used as a direct replacement for the standard ETX-125 by simply removing the adapter and inserting it into the fork mounted black plastic housing if one so desired. Personally with the fine design of the ring support/mounting system by Ken Dauzat, I wouldn't bother! The visual back can be removed for collimation, although I have never needed to do this.
This OTA was aligned by Meade Instruments using the Star Test Method. This OTA is in perfect condition and has been only used a couple of times by me and once by Ken Dauzat (from Ken's Rings and Things- a sponsor of A-Mart)showing off his final modified design a few weeks ago at the Kisatchis Star Party. Ken told me that it out-performed many larger scopes (10" & 12" SCT's) on Jupiter for fine planet detail. He also stated that this unit will rival almost any 4 to 4.5" APO in Lunar, Planetary and Double Star performance. I can attest that from personal use that the images are very sharp! Ken's design incorporates a very heavy duty GP/CG5/Atlas type dovetail bar integrated to a rotating center ring with two finders. One is an matching white 8x50 finder that incorporates a finer crosshair system than Meade provides. The other was a red dot finder which I easily switched out for a Televue Sol-Searcher Finder. The large knob on the Center Ring locks the ring in place. The two outside rings are felt insulated from the central ring and are attached to the dovetail mounting bar. The rotation is very smooth and precise. The Finder bracket and rings are nicely machined out of aluminum and finished in gloss black lacquer. There is also a black anodized aluminum lens cap/cover for the front of the tube that screws in place to protect the optics. The Front lens was not coated. I was informed by Jim Wegat and Ken Dauzat that this amounts to only about a approx 4% light loss. From personal use I didn't see a noticable difference. I will also include a Scopetronix type A Glass solar filter with NO pinholes that provides a nice white image of the Sun...this is set in a black anodized cell which screws in front of the corrector plate for safe solar viewing.
This has none of the junk on the back of the OTA like a flip mirror, No fork tines. Also included in the package is a brand new condition Konus EM-10 Equitorial mount. This comes with factory installed dual=axis drives with hand controller and a polar alignment scope. Two 9.5 lb. counterweights are also included. The mount is rated to carry around 30#. It accepts (of course) the Vixen type doevetail bar already incorporated into the scopes system. Thanks for looking!
