Hi, I posted an issue over in CN Software, but I don't seem to be getting someone who may know the answer. I decided to map out and see about improving the basic PE in my mount using PEMPro. I have solved an earlier issue with connecting the mount and camera, but now, on the data gathering runs I have made o far, I can't get the log files to consistently suck in all the complete mount/camera scale information and tracking data for that run that allows proper analysis and follow-on PEC curving when reviewing the data. There has been a few occurrences when it did get all the right info, but I can't figure out why on some runs and not on others, usually the ones that worked are after I repositioned the scope, but I don't think it has anything to do with the repositioning, but rather with the integration between the information coming from ASCOM on the mount and camera, versus what is loaded into PEMPro directly or as default. Or maybe the way I connect the devices, but I have tried different things and there is no consistency to when this happens and when it doesn't. I have run the mount wizard and the calibration wizard, I get thru those ok, but it seems to have no affect. On the log files with the missing info, PEMPro wants to use its default values (such as worm period of 10) to create the PE chart and PEMPro Log Viewer will not properly run on those files at all because of the missing info (it doesn't have default values) , if I cut and paste in the info from the runs that did work I can get Log Viewer to work on those files. On the collected data side, on those data runs that have the missing mount/scope info, there is also a missing data element that is seemingly important, it is the value in the column with the Controller Step for each exposure, that seems to be important for curve loading, it puts 1's in there instead of the step location....below are examples. I am sure this is something simple, like what I am connecting first, or how I set up for the runs, but can't figure it out. BTW I do have to Bin 2 just to get it to work thru calibration due to the file size on Bin 1 on that camera. Any ideas are appreciated.

Forgive me if this is posted somewhere, but I did a search and I couldn’t find exactly this. I am at a fork in the road on building my observatory. Either a very small outhouse type covering just my G11G on a pier or a bigger observatory where I can put my scope on the G11G that on the heavy duty tripod. The first is super cheap. The second is super convenient. If I go the first route, I will take my scope off after every imaging session and then put it on to start the next one. I only get two image sessions at most a week for a couple hours a night, and as usual for most of us, there are long sessions of weather, full moon, etc. where I cannot image for weeks at a time. The scope will be kept fully assembled and wired up in a warm room about 10’ from the pier when not used. My scope is a Stellarvue SVX 140 and loaded up it pushes 35 pounds. If I very accurately PA the G11G on a pier and then set my scope on it for the next session will the PA stay accurate for doing this many times? Avoiding PA most of the time is the main point. This is the last question on which route to go. A permanent pier with a removable scope and a very small outhouse type of rolloff building (or even lift off) or the much bigger affair where I just turn the power on after rolling off the roof. Many thanks

I just received a new Titan axis upgrade for the Losmandy G11. It is a beautiful piece of kit. After balancing the axes and selecting the G11T in the hand controller, I moved the mount on both axes to make sure everything was working smoothly. In the new RA axis, I'd hear a ticking sound. The mount has some weight on it (about 45 lbs) but everything is well balanced. When I removed the RA motor and ran it from the hand controller, there was no ticking sound. Adjusting the tightness of the motor against he gear housing did produce much of a change, though I thought I noticed a much smaller tick slewing eastward versus slewing towards the west. The ticking is at very regular intervals at maximum slew using the hand controller (perhaps every 0.5 sec). It does not seem to affect slewing at all and there is no binding to the point that movement stops in any orientation I've checked. When the RA motor was attached to the G11G, it did not make this sound. The Axis upgrade calls for using the RA axis motor from the G11G for the G11T. Settings in the hand controller are those necessary for the G11T in terms of gearing. My first thought was a possible gearbox issue, though this seems a little less likely coming straight from the factory. Another thought, coming from my G11G days of two days ago, was perhaps the RA worm gear needs some adjusting? There is probably a good 30 degrees F in temperature difference between my location and where the worm gear was originally adjusted; however, I've read that these are properly adjusted at the factory. I'm not a natural tinkerer. I was recently befuddled by a focuser screw. So while I adjusted the worm gear on my G11G, I was absolutely certain I needed to. Now, I'm not so sure and would rather get some further information before taking things apart and coming to the usually problematic realization that there are extra parts. First, is this clicking sound actually normal for a new mount? If this sound isn't entirely normal but everything is working as it should, should I just use the mount under the rules of engagement regarding things that aren't broken? If tinkering is required, what are the areas I should look to tinker in? Gearbox and...? Thanks in advance for all replies! Regards, George

Hello All. I have an issue with Astroart 8 and my G11 Gemini 1, specifically AA8 calibrating commands not getting to the mount, or that’s what it seems like anyway. I have a QHY5Lii guide camera output plugged into the autoguider port of the Gemini 1, and tried all available Guide dropdown menu options available under the AA8 Telescope Control panel. I got the “mount didn’t move” error, meaning the mount didn’t receive any commands, no matter what selections used. Im using the ASCOM Diver from the Astroart website that pulls up the Gemini software and connects to the mount successfully. Lastly, using PHD2 with the same cabling/connections the mount calibrates and guides well, so I know the hardware and cabling are fine. Just to note I did put the Gemini hand controller in all speed mode and tried all combinations of the Async Pulse Guide and Precision Guide Pulse software settings but to no avail. Any help is greatly appreciated. Joe

Hello, This weekend, I considering purchasing a Losmandy G11 with the latest Gemini with the last version of the Gemini-1 controller with untucked motors. The drive is about three hours. This would be my first German equatorial mount and my knowledge is limited. The present owner does not know anything about the mount, it is an estate sale. What should I look for - technical details and operation of the mount? A broad question, any pointers and ideas would be greatly appreciated. Included is an Explore Scientific ED127 with large Orion guide scope with an Orion StarShoot Autoguider. Utimately, my goals are astrophotography. Are there software limitations with this older version? Thank you, Tom

I know the stated capacity of the g11t (75lbs imaging 90lbs visual) but having this mount for a few months I think that's overrated. I think a 16" SCT (67lbs) for planet imaging is definitely pushing it. I'm looking for some feedback from anyone who has their g11t loaded, over 70lbs.

Want to sell my Gemini II controller GM811 with Pier extension and larger saddle. I find getting it out, down the stairs and setup each night a bit to much for my 70 year old body. I am thinking $2,200 plus shipping.

The ASCOM platform team published a quick fix to the compatibility issue reported earlier that affected Gemini.NET driver and ASCOM Chooser. Platform 7 update 1 is available for download from https://ascom-standards.org website and is safe to use. Regards, -Paul

Greetings, Been running my G11G for a couple of years now. My backlash was needing adjustment, and now after trying to follow online tutorials, it's really needing adjustment =D. Can anyone post their personal tips, tricks or advice on how to get my mount back to spec? Thanks in advance, -Jonathan
