ITEM FOR SALE

Vixen SXW Computerized, Equatorial Mount with Starbook Controller

I purchased this mount with a Vixen 8" Astrograph on top of it from the estate of the past president of the Riverside Astronomical Society, the astronomical portion of that estate being sold off by RAS at a past RTMC gathering. I sold the astrograph some time ago but the mount has been my primary solar observatory mount for several years now here in Flagstaff. It comes with the manual, deluxe tripod, Starbook controller, two factory counterweights, and any features which were standard equipment on the original unit. Weight capacity is stated to be 35 pounds. It has a Vixen dovetail rail mounting. This mount is easily light enough to be transported and I occasionally drag it down to Camp Verde in the winter months to continue the solar work while staying in our trailer.

This is a very sophisticated mount with an exquisite controller system, the Starbook. It has been very happy with a coaxially mounted Lunt 80mm double stacked solar scope and a Stellarvue 80mm triplet with a Thousand Oaks white light filter on it. I also run a Celestron 9.25" cassegrain on it for planetary.

This is a very good deal at $1000, exactly what I paid for it. If it makes it easier, I might be open to a part trade. I'm open to driving down to Cordes Junction or so to meet.

The SAC ATM (Amateur Telescope Making) / Astro-Imaging meeting was held on January 2, 2018 at Paul's home shop. Attended by Paul Lind, Al, Chet, Lynn, Michael and me.

Oops, Vendor Sent Wrong Adapter for Focuser A Pier Plate Fabrication Search

Michael Poppre brought in his Explore Nikul Suthar came in asking about where he could Scientific ED102 Refractor telescope to install his get a steel pier plate fabricated for his observatory brand new MoonLite focuser on it. First thing he pier. Paul suggested that he talk to Mike Collins, as he did was remove the focuser from the tube to see has had a lot of experience in doing that. Paul also said how it was mounted. He wanted to validate his that he should make a drawing of it so that it could be known how much material that would be needed for suspicion that he had received the wrong the job. mounting adapter for his scope. Sure enough, he was right. Lynn took one look and noticed the focuser had threads on the outside. It should have had the mounting threads on the inside. (The telescope tube has mounting threads on the outside of the tube.) So that was that, and he put the old focuser back on the telescope tube and will contact the vendor to have them send the right adapter.

Epilogue

A look at Michaels' telescope with the original focuser That’s all for this month, see you next time. Remember, if you have a “need” for your telescope, bring it over to Paul Lind’s shop at the Testing a Guider CCD Camera next SAC ATM/Astro-Imaging meeting on the Tuesday evening before the SAC general meeting Lynn Blackburn brought in his guiding ccd and join in on all the fun. Paul will post the date camera that was not working. He sat down at on the SAC-Forum list. Hope to see you there. It’s Paul's laptop computer and tried to run it but still a fun time for all. no worky. Then he swapped out the cable and it still would not work. Then he decided to look for the driver for the unit but was unable to find it on line. Not sure what the outcome of this problem is. I guess we will find out at the next ATM meeting.
