I am resetting my guiding after some upgrades and a couple of months of inactivity. I am running an ES 127 with a 180mm guide scope and a ZWO 2600C mounted on my GM811G. I have the latest PHD2 and have upgraded my Gemini 2 to V6.2. My first runs were marked by a strong DEC drift that did not respond to guiding pulses. I've had this problem before. Since it had been a couple years since my last maintenance, and I just got the cleaning and lube kit from Losmandy, I decided to take both the Dec and RA axis apart and clean and lube. I also opened my DEC SLW gear box and cleaned, lubed and retightened. Had to watch Scott's video on this several times to get it set, but it seemed to slew well last night, though the DEC drift was still present in guiding. Tonight I am I am working through my notes from my conversations on guiding and recurrent DEC spikes/drift that I had with Brian and you all a couple years ago. As I do a careful rebalance, and a careful PA and in prep for another a calibration (bumping north first), I want to be sure I have my PHD2 set right. Attached are screenshots from my calibration last night (PA was not careful and seeing was poor), and the Guiding and Algorithms pages in PHD2's Advanced settings currently in place. In particular, what about the "Use Dec Compensation" and "Reverse Dec Output after Meridian flip" options on the Guiding page and the "Declination" and "Backlash Compensation" options on the Alogrithms page? I'd be glad for any suggestions.

Hi Everyone, I would like to ask for your suggestions, as I bought a second hand G11 with Gemini I and I would like to do astrophotography with it. This particular unit has spring loaded covers for AR and DEC, but they were not made by Losmandy. Apparently, it was a "European version" of a spring loaded system, from somebody called HAS, but can't really get more info about it. I find it very similar to the Losmandy solution and I can adjust them in the same way that Scott's youtube videos show. Pics attached. When testing the Guiding Assistant in PHD2, I found an RA peak-to peak of 17.7 arcsecs, and a suggested maximum exposure time (due to drift) of 0,6 seconds due to very high gradients in the curve. Pic attached. From my understanding, this would be a good example of an old style worm (silver looking). But to my surprise, when I opened the worm cover, I found the goldish looking High Precision Worm! I would expect a smoother RA tracking behaviour for a brass worm... Any comments here? Prior to this test, I dissasembled and regreased the DEC and RA shafts, but not the worms and dented wheels. Would it be a good idea ot clean and regrease them? Would this step be your first suggestion? I don't mind to dissasemble components and get some replacements purchased for this mount. Regarding backlash, I managed to reduce it a bit, but not able to remove it below 6 seconds drift when changing directions (on a terrestrial object, with no sideral movement and a guiding speed of 0,5x) I found the DEC gearbox to have a loose cover (the plastic box), so I'll order a replacement, as I guess that DEC backlash is due to this. Thanks in advance for your suggestions! best regards from Spain! Juanma Rivero

Folks, Gemini L6.02 firmware and Hand Controller v1.61 firmware are now out of beta test, and available to everyone. This version enables full use of PEC with L6 and with PEMPro. In addition, it addresses some issues reported by the Southern hemisphere users, and adds a few new serial commands that make Gemini controller even more powerful. Steps to update 1. Update Gemini firmware using the latest GFU utility, v1.0.31 https://gemini-2.com/GFU-download.html. Update HC version also if yours is older than v1.61, by checking the HC checkbox near the top of GFU window. 2. If you use PEMPro, install v3.10.07 or later that's compatible with Gemini L6.02 from here: https://www.siriusimaging.com/PEMProV3/PEMProV3_Release_v3.10.07.exe. Follow instructions by Brian Valente for using PEMPro with L6: /g/Gemini-II/files/Gemini%20L6.02%20beta%20files/Losmandy_PEC_Primer_for_L6.pdf 3. If you use ASCOM, you may want to update your version to the latest driver (v1.1.25): https://gemini-2.com/ASCOM.html 4. Latest serial command documentation is available: https://gemini-2.com/web/L6V02serial.html NOTE 1: If you can't use GFU, you can still update the firmware to L6.02 by using the combined firmware file from here: https://gemini-2.com/firmware1/combined602.zip and update Gemini using Gemini web pages or by copying the appropriate files directly to the microSD card through FTP or by removing the SD card. NOTE 2: Remember to also update PIC controllers to v3 firmware to get the 4x encoder resolution if you are upgrading from L5. You should see this in the Gemini web pages after the update: Regards, -Paul

Hello support group I can’t seem to find the link to download the latest gemHC download in order to drop it into the hand controller box on the GFU as my version is 1.160 not the latest v 1.61 what’s the latest HC version and where is it in the file section? Thanks Ron

Hi, Today I reveived my new G11T from Losmandy. There is a 1/2" allen wrench bolt on both sides of the mount in the middle of the altitude adjustment screws. They were loose when I unboxed that I presumed was for shipping purposes. So my first thought was that the bolts locked the altitude adjustmant in place after polar alignment. But after adjusting the elevation with the large knob in the rear and then tightening the bolts, the elevation still turned without added effort. Any idea what the bolts are for and how tight they should be. I added a photo below. I checked the User Manual

Good afternoon, I'm trying to narrow down an upgrade for my atrophotography. Right now my imaging train consists of an 80mm APO. I'm looking to purchase a larger telescope to add to my imaging (120mm APO) and will need to get a larger mount. My existing mount is just enough to handle what I currently image with. I'm very interested in the G11G. My only problem is that I cannot find any recent reviews from the last few years, from 2021 to present. I would really like to know how the new G11G's are performing, problems, etc. First question - my existing imaging train is only 14 pounds. Will I still get good guiding with being that much underloaded from what the G11 can actually carry? I have been told that large capacity mounts do not perform well with small loads. I would have to think this is false. Do the spring loaded worms on the new mounts need to be adjusted or do you just use the mount right out of the box? How tight do you make the clutches? Should you still be able to move the RA axis and DEC axis with decent pressure from your hand? I'm used to locking down the clutches and the RA and DEC don't really move unless by force. Is there is excessive dec backlash that seems to pop in reviews or is that just something that may happen? I understand that not everything made can always be 100% perfect. Things happen. People talk about fiddling with the mount. Reading things from Losmandy and other reviews, everything points to just use it, don't make any adjustments with the new mounts, don't fiddle, etc. I know these questions have been answered in the past, but that's the problem. I would like to know about the newer mounts, not 10 year old, 15 year old mounts. I also know that problems, bad reviews, etc. get posted more than the good. You really do not get a good picture of how things really are unfortunatley. I know I have viewed all of the Losmandy tutorials on their youtube channel at least twice. A new reliable mount is a lot of money. I just want to make sure. Any information is greatly appreciative. Thank you.

I have a G11G, and just got a 130mm Stellarvue refractor to image with. I've got an 11lb and 20lb counterweight currently, trying to figure out if I should use more. The scope weighs I think 21lbs with rings, and adding the camera, flattner etc I expect to be about 25-28lbs. Seems to weigh less than my fully loaded C11, but the 30ish lbs of counterweight didn't seem quite enough for that scope. The weight is much closer in with this refractor. I can get it to balance, but won't be able to test under the stars for tracking for quite a while based on forecast and travel plans. I had posted here before an a number of folks were using refractors in this class/weight range. What did you find was the 'right' amount of counterweight? Brian

Always wanted to get my mount to have partial through the mount cabling. Rebuilt my power box and got the cables down to 1 silicone power cable and a thin flexible Ethernet cable. After some thought, I found a way to avoid cables affecting the RA axis. After running slewing tests in the house, I had 2 clear nights this weekend to try it out. Cable did not catch on or touch anything. Guiding was great! Just had to make one small 1/4-inch channel in the RA extension.

I have a new G11G carrying a ~50lb payload. I wasnt able to balance the payload very well (even setting the Altitude to horizontal). So I opt’d for the wavy washer upgrade. I just installed it tonight and am concerned the clutch will no longer tighten enough. Before the wavy washer install with the RA on the bench if I fully tighten the clutch knob no matter how hard I try I cannot rotate the RA by hand. With the wavy washer installed and the clutch knob fully tightened I am able to palm the RA extension and rotate the RA by hand. I don’t see how this could hold a 50lb payload without slipping. Am I missing something?

I was thinking of using a CGE Pro tripod to support my G11. How would I connect the G11 to the CGE Pro tripod? Chris
