Re: G-11 Meridian Flip with ASIAir Pro
Jim- Did you figure this out? I just a G11G (used). Everything is fine with my ASIAir Plus, except it does not meridian flip. I have to go to pause the Plan in ASIAir, go to Home (CWD position), then

Re: GM811, PHD2 and Non-Periodic RA Spikes
I'm sure doing this is fine but I'm not sure what you think is going to happen. If there is debris somewhere in the drivetrain or there are sticky bearings due to contamination or using the wrong

Re: GM811, PHD2 and Non-Periodic RA Spikes
Would there be any harm done in simply running the mount back and forth a bunch of times to its East and West limits on both sides of the Meridian? This might smooth-out whatever is causing the spikes

Re: GM811, PHD2 and Non-Periodic RA Spikes
Chip, I keep worm end play controlled by manually pushing the outside worm block toward the motor as hard as I can while tightening the block with my other hand. Michael Herman's paper is this one, I

Re: GM811, PHD2 and Non-Periodic RA Spikes
Observing the guiding, one might contend that it resembles the primary mirror support. An Off-Axis Guider (OAG) would detect when starting friction permits a minor deviation in the optical path.?

Re: GM811, PHD2 and Non-Periodic RA Spikes
Hi Paul, The caliper greases work but start to get very tacky over time as they lose their solvent content. Please send me a PM and I can send you a sampler of MP-50 at cost (the smallest can online

Re: GM811, PHD2 and Non-Periodic RA Spikes
Chip, interesting comment. I habitually readjust worm block spacing outdoors every October and March (or thereabouts) because of the seasonal changes here in WNY. I may have had this RA spiking issue

Re: GM811, PHD2 and Non-Periodic RA Spikes
Wait, before you bother to strip the mount think about what the mount is doing as it gets cold acclimated.? Your classic Losmandy 2-piece worm drive system mount will never have as low backlash as

Re: GM811, PHD2 and Non-Periodic RA Spikes
UPDATE on my RA spike issue: I swapped RA and DEC motors but the spikes stayed with RA, so I've ruled out the motors. There are no more clear nights for the time being, but my next experiment will

Re: G11 guiding perfect until last night
Sorry for the late response. Cloudy until tonight. Guiding is not as bad as before, but not better. Ranges from .8-1.2. Going to replace clutch pads and wavy washer. Maybe I should clean the worm

Re: G11G and ASIAIR
I actually disassembled the tripod and machined the top to provide a relatively precise hole for the 1/2" bolt and a smooth flat surface for the Losmandy base plate to rest on. The anodization on the

Re: G11G and ASIAIR
Yes, just some best practice thoughts. Aligning the four G11 mount spirit levels sets the mount into a mechanical position that corresponds with the initial Gemini-2 encoder position. The starting

Re: New G11 + ASIair guiding issues
Sorry that I missed your reply. I appreciate your thinking of me. At this point I am able to guide this mount at 0.40" or better reliably. Using PHD2 or an ASIair. I am not completely sure what made

Re: GM811, PHD2 and Non-Periodic RA Spikes
All, After an additional night of observation and a slight tightening of the RA clutch, the random spikes are still there, not frequent but consistent. I'll check the lubricant that I used (actually

I appreciate your help. So by spirit level, I would guess you mean the "CWD" position the mount knows after a cold start. I've gotten to doing things this way: set up the mount and ota, balance then
Re: G11G and ASIAIR
Asi Air sets only a minutes BEFORE meridian to pause imaging.? Minimum value is 0.? You can't make it go past the meridian before pausing. You then need to set your Minutes After delay to make sure
