Hi Bill, My bad! The topic read GM8 and my brain left off the '11' in the body text. Yes, the GM811 will not have the same mechanical interference issues as a standard servomotor GM8 and the

I noticed today that the product page for the GM8 now shows 30 to 40 pounds ( http://www.losmandy.com/gm8.html http://www.losmandy.com/gm8.html ) based on the OTA configuration. Is there some

Still looking if someone can measure the depth of the threaded blind holes used to attached a saddle to the DEC head on any GM8 or GM811. Stephen Pizzo (good guy to deal with) had sold a number of his

This is a brilliant solution to reducing carrying weight, providing more clearance, and at the same time making it simple to remove/replace the DEC axis. David

Good comments Chip, My unit is the GM811, so its "GM8" DEC axis already has the tucked in motors (which I agree are very nice) and the new OPWs. Also I purchased the GM811 and had Scott put on the RA

See the nice photos of the standard parts, and possible rearrangement of the parts order, at Mark Crossley's valuable website: www.WilmslowAstro.com It's on one of his many pages, but the first page

There s/b a washer (race) touching each side of the thrust bearing. Are you certain it is not just stuck to the aluminum bearing housing? -Jeff

David, Yes, with PhD, PhD2, or any other program that supports the ST4 interface directly from the guider (your STi has the ST4 itself - it is the modular phono jack right next to the USB cable). Or

The old G11 Celestron model I recently got may be missing some parts. Both clutch assemblies have the following: knob - spring washer - thin washer - thrust bearing...and that's all. Isn't there

Yes. I have used the sti on my CG11 using ccdops and ccdsoft software. Works great ??. Joe Sent from my iDork

Will the SBIG ST-i interface with the Losmandy G-11 492 system of Celestron era? I recently picked up such a G-11 and I happen to have a ST-i. Thanks for any advice. David

Hi Bill, Consider this upgrade carefully. The GM8's saddle may have been kept as short as possible for at least two reasons I can see. First, mechanical clearance of the saddle. The standard Losmandy

I wonder if that upgrade has primarily been purchased by G11 owners? Thanks Brian Brian Valente Brianvalentephotography.com Sent: Thursday, November 9, 2017 10:30 AM To: Losmandy_users@...

Folks, Replacing the stock "short" Losmandy saddle on my GM811 with one of Stephen Pizzo's RAYOX saddles. The stock Losmandy saddle is mounted with two 1/4-20 socket head screws that extend 7/32"

Thank you. g

Gemini Calculates Refraction setting has to do with goto precision and not with tracking. That setting simply tells Gemini to adjust the goto coordinates for the effects of refraction. It does not

Yep, pointless. There have been 1,243 posts made on this forum over the years about this subject (I counted them...) and I believe the consensus agrees with my personal findings - tracking error log

Hi Ray, Your guess might be right that with "Gemini calculates refraction" turned off, there could be a difference between zenith, say, and East or West directions. Comparing E and W at the same angle

Hi Michael, I am not sure it has been solved. However, without tracking rate correction a mount will always appear to be tracking slightly fast when it is tracking at perfect sidereal rate and
