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

Hi Ray, Thanks for that ...I did understand that but.... I somehow missed the statement that the first step: get AZ correct by the drift method, while pointed at Meridian and Equator, must already be

Yes, but as Greg said, this technique is different in that it uses RA drift at the zenith to adjust Altitude polar alignment instead of standard Dec drift in the East or West. There are advantages and

My mount is the G11-G.?? I beleive I can manage my power needs with a 10a supply.? Just to have a little extra.? ? Les, thanks for the link for the Canon switching regulator.?? 30V 10A

Pointless? I would disagree if you wanted the best tracking you could achieve. Three factors play into the alignment: 1: Has the polar-scope been calibrated to the mount? If not the mount is

Thanks to all for your comments on this issue. I believe it is clear that having a precisely level mount does not preclude an accurate polar alignment or accurate GOTO performance. Certainly, as Chip

Magnus IMHO "interrupted" can only come from one of four things: A): A handset Ra/Dec button was activated during slew (either by touch or electronic failure, aka a momentary short cct); or
