“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy.

Quote:Which brings me to my conundrum. Should I upgrade to the CGEM DX or the Losmandy G11/G2? I'd save 1200 bucks going with the CGEM, but I'd gain 10 more pounds of weight capacity if I went with the G11. This is a Buridan's @ss dilemma for me.

You would also gain more precision with the G11. How do you plan to use it? That would determine whether it is worth it to spend more.Gale

Quote:I had a chance to play with a CGEM at the last club star party. I fielded an Atlas. It was nice to see both mounts in action at the same time.The CGEM is better finished, and much more ergonomic than the Atlas. It goes without saying that the Nexstar firmware is light years ahead of Synscan on the feature front. The CGEM also slews to targets MUCH faster than the Atlas (I'd estimate >2x the slew rate).On the other hand, the CGEM is much noisier in operation than the CGEM, and the particular unit we were using suddenly bound up in its declination axis during the session. It had been "hypertuned" professionally, and I suspect something had been either meshed too tightly or left too loose. By the cold light of day the owner discovered that the declination worm adjustment screws were loose, and tightening them fixed the glitch. Whew!My Atlas hasn't missed a day of school since I bought it many years ago.I really liked the CGEM and if I was going to refresh my aging Atlas, I'd definitely consider it. My only misgiving is the less than stellar reliability reports and my own observed failure of the unit I had the opportunity to use.Regards,Jim

Quote:IMO, shipping mounts and telescope long distances is a fact of life. If manufaturers are making gear that cannot be shipped and still perform to a certain level, then that is a problem. Upon arrival, ANY of the gear from ANY maker, should perform to the documented spec. And it's NOT the carriers fault. We too often want to blame UPS and FEDEX. Poor design and packaging are the main reason things arrive out of spec. Can you ship Eggs via UPS.....? Sure you can, but not in the catron you buy at the supermarket. But as we learned in school, you can make a carton or package to support dropping the egg from the 2nd floor window without it breaking. Telescope and mount makers need to make gear and packaging the can live within the current delivery systems because we aren't going to pick everything up at the shop 3,4 maybe 5 cents Joe

Quote:Just to add to that - Celestrons packaging is as BAD as it gets. They ship a $4500 C-14 in less than 100lb burst strength cardboard. They only support and protect the tube at the ends with foam. You can push the box with your hands until you hit the tube at the center. If you are to use the same box again to send to someone else it will fail. Then everyone is mad at UPS/FedEx when they won't pay a claim. Joe
Quote:Just a quick set up question: how much should you tighten the RA and DEC knobs after balancing? With my Sphinx, I make them good and tight but every mount is different.
Quote:Quote:Just a quick set up question: how much should you tighten the RA and DEC knobs after balancing? With my Sphinx, I make them good and tight but every mount is different. The clutches on the Sphinx work much differently from the CGEM. If you clamp down on the CGEM clutches you will slightly deform the ring gears and the mount will run very poorly due to the gears no longer being round. You need to use as little pressure as possible on the CGEM clutches.
Quote:That's good information to have! I just acquired a used CGEM and the last thing I'd want to do is damage it, ham-fist style.

None of my kit is part of a two year pay to be part of beta test, that still isn't close to ending.
Quote:On the other hand, I've never had to touch the Atlas in this regard. Mine is many, many years old, is well traveled (including many off pavement dark sky trips) and has not been treated gently in any way. I find it strange that a much younger and less traveled CGEM would manifest this issue unless caused by human intervention, when a much older, untouched, more abused Atlas would not. Would it be legit to use Locktite blue on these screws to avoid having to deal with the loosening screw issue in the future?- Jim
