Re: New Guy
Louis Mamakos
Hi, I'm yet another new guy.
I'm getting close to ordering a 900GTO mount (or at least getting the waiting list to order, sigh). I had a question after I looked at the price list (gasp!) on the A-P web site. Given the Go-To capability of the mount, is there any point in adding DSC encoders on the mount? I would think that they would only be useful if you decided you wanted to move the mount by hand, rather than using the drive motors to do so. I also get the impression that using the GOTO capability is likely more precise than the resolution of the DSC encoders that you'd install. louie

From: "Rich N." <rnapo@znet.com>I agree. As far as me and my 600GTO are concerned its an academic question. That is my understanding as well. However being an engineer I'm interested in what design features Losmandy optimized (bearings, high torque motors,...). So far all I've heard leads me to the conclusion that there really isn't a significant difference between the CAPABILITIES of the mounts; just their specs. It is also relatively inexpensive.

Re: 600 GTO payload capacity

So does anyone believe there is cause for concern about the longA C14 on a G11 mount is quite stable for visual use. Why push a very nice, not inexpensive, mount like the AP600GTO by loading it down with a C14? Once when I wanted to compare my old AP 152mm f/9 StarFire to my new AP 155mm f/9 EDT StarFire, I mounted the older StarFire on Celestron SP mount. With extra weights and careful balancing the SP motors drove the big OTA very nicely. Apparently the G11 is designed to take a heavy load. It is also relatively inexpensive. If I couldn't afford one of the larger AP mounts I would feel much better taking a chance with the less expensive G11. Rich

Re: 600 GTO payload capacity

Hi Charles,
I like the 900GTO too, I bought one. But the G11 is amazingly stable even with a C14. Maybe it has more to do with the Losmandy semi-pier and tripod. Rich No way, the 900 GTO is much much larger then the G11. I have owned bothand in every way more then the G11....though the 600E and the G11 (while Iwould lean on the 600E greater) is a much more reasonable comparison.

mounts and I would put the G11 at the 600E size, Definatly not in the same league as the 900 gto. I have owner both mounts and have used the same size scope on them and the 900 is significantly more stable and load capacity and in every way more then the G11....though the 600E and the G11 (while I would lean on the 600E greater) is a much more reasonable comparison. charles

While waiting for our Biblical sequence of rain
storms to pass here in the San Francisco Bay area I've taken to idle speculations... Anyone care to speculate why the 600 series mount is is rated to carry a SCT size of 10 inches max where as the Losmandy G11, which is not that much different in size, routinely carries C14's ?

Low Resistance Electrical Connectors
Tim Khan
For those that are interested in the connectors.....
Fwd Attachment: They are called Anderson Powerpoles in the 30A size (they also make huge ones for 1000Amps), its a standard industrial connector and available from hobby shops that cater to Electric Planes RC or Cars..they usually are renamed to be sold to the RC people as Sermos, or Cermo or LigthSpeed connectors. They are all the same. This company sells them as Anderson P.P. http://www.newcreations-rc.com/batteries/conectors.htm this is where I usually buy, $13 for 10 pairs.. this company sells them as "Cermo" for $1.50 a pair http://rc-aero.com/biz/bandt/ Herm __________________________________________________ Do You Yahoo!?

Since it is the middle of winter it seens unlikely that the keypad would be able to overheat. I still would double check your power connection (wiggle it) to see if you get an intermittent power loss. -Ray Gralak

are you saying your keypad completly shutdown. Ie: goes back to the opening menu, where the version number is displayed?? or do you see it blink, and then you are back to the point where you left off?? if it goes all the back to the begging then this is a power issue, or something in my code is blinking the unit into a reset. I do not see how ...but it is something we have to look at. please report everyone what version numbers of the code you are running on the hand controller?? - Charles Sinsofsky Astro-Physics Inc.
