This week I updated to L6, and tonight was my first night out. Immediately I encounter an odd error that I previously had when I first got my mount. This was best emphasized in N.I.N.A. when I attempted to slew to M81 through the framing tool. First I start getting this error "DEC coordinate is invalid or inaccessible". To be honest I was messing around so much I do not know what I changed that got rid of this error. But what came next has me perplexed, and this is what I was experiencing when I first got my mount: So M81 is RA 09 & DEC +69 (per Cartes du Ciel). In Framing tool NINA reports the same. But what NINA slews to is this: 05/18/2024 23:28:31 09:58:45 49° 24' 17" 19° 47' 52" -00:03:46 19° 47' 33" -2390.23 50267.75 179.38612877930223 Cartes is showing the cursor right over M81, yet plate solving is way off. Better yet it does slew to correct and I get this: 05/18/2024 23:28:05 09:25:10 89° 21' 45" 20° 10' 27" 00:03:42 -20° 10' 27" 2347.97 -51221.63 171.84309889679707 And it goes right back to where it started and 05/18/2024 23:27:39 09:49:14 48° 36' 51" 20° 35' 31" 00:05:44 20° 34' 48" 3640.97 52263.55 179.40811750502564 I restarted Gemini multiple times, even did "Reset SRAM to Factory Defaults". I went to Gemini site and double checked my address to get the coordinates Latitude & Longitude: 45:03:52 -94:02:40 From the mount: Longitude -94°02'40 Latitude +45°03'52 I even tried messing with the time zone offset changing from -5 to -6. This was the problem I had when I first got the mount. I would slew to a target and I would be off as if my time was off my 3-4 hours. Stranger still when I slewed to M101 up around Meridian at this time, my telescope was pointing south when, as if my location was off. Another strange sign was when I slewed to Alp Lyr which was about 35 degrees yet the telescope started to slew as if it was something odd like 5 degrees altitude. I do have a NTP server, and it does appear to sync. The mount currently reports accurately the time from the web UI. One thing to note that I do not believe would have been a factor. I did get the side by side but I don't see how that would have affected anything except if some weird bug in new L6 firmware when rotating DEC.

I recently upgraded to Level 6 (6.02) and decided to run new PE measurements and generate a PEC curve. I've run into a toothy/jagged PE measurement. I had this issue before with L5 and the solution for this was to adjust ADU values for the star used for the measurement. It is not working in this case. I am using the latest version available of PEMPro (v3.10.07). Things I attempted: Adjust exposure above and below 2 minutes (images below are from 0.5 seconds and show the same pattern as they do at 2 seconds) Choose Losmandy G11 rather than Gemini 4/5/6 as the mount type Choose worm cycles at 2x and 1x within Gemini. Adjusted ADU minimum ADU values as low as 3,000 and maximums as high as 20,000 (5000 for low and 15,000 for high had been original settings) I ran calibration wizard though settings and angles are unchanged from my previous successful measurements. Considering the work that went into getting PEMPro v3 functional for L6, I suspect something related to user error (v2.0) is going on here. An interesting side note, I loaded my old PEMPro-generated PEC curve into Level 6 and have run it for two sessions since updating from L5 to L6. These have been my two best guided sessions ever with this mount. Admittedly, two sessions do not equal evidence of better real-world guiding performance with L6 since there are so many variables that can influence guiding. They are still well within the realm of coincidence, but it is a coincidence that I am liking. George

Hi all. Haven't posted here in a long while, mostly because my G11 and Gemini have been working like a dream mount. I've had the mount for 10 years, and made a few upgrades that have improved it substantially. My question is with regard to the Garmin GPS that Losmandy sold with the level 1.04. I tried to use it last night, and it connected with the Gemini just fine, but once the time/date, and location were updated, I noticed that the time and date were wrong. I tried it a second time, with the same results. The lat/long coordinates were correct. I know that there has been a recent glitch with GPS units all over, so I was wondering if this might be the cause. And if so, what remedy is available to me. Thanks in advance for any help I can get from the group. Ron Yates

I own a Losmandy G11-Gemini 1. As AAVSO member I’m working in variable stars. My last session was two nights ago. The work was fine in the first night: connect to TheSkyXPro via “ATEN USB –Serial Bridge”, using ASCOM v6.6 as mount, find the star, slew to it, taking images, and so on. But during the second night it was impossible to connect the mount to the planetarium of PC (Windows 10, ic7) through the “ATEN USB –Serial Bridge”. The PC showed that the bridge was connected. I restarted the computer without results. I used NINA and Stellarium, nothing. After I chose GM-11-G Equatorial Mount instead of ASCOM, nothing. I changed the ATEN, with the same result. Finally, I used other PC, the same. If the problem is not the planetarium, the PC, the cable, the conclusion is that the problem is in the RS-232 port. Are you agree? All the other devices connect without problem. I would greatly appreciate your advices. If the RS-232 port is damaged are there solutions? Thanks. Luis Barneo Oviedo, Spain

Hi everyone. I'm back from the eclipse trip, happily imaging with my GM811G at L6. For the most part everything is going great. Seeing has been really good lately and I've seen total RMS dip into the 0.2's which is the best that I've ever seen. The issue is that RA is usually higher than DEC, something like 1.5 x to 2 x, and I can see really good data, but the stars are elongated. I don't see the elongation very much when the seeing is not quite so good. When RMS tends to be around 0.5 to 0.4, the random jitters from the atmosphere seem to average out better and I get round stars. Data is not nearly so beautiful, but the elongation is not apparent. Any idea how I can tame the RA when seeing is exceptional? I have successfully trained PEC with PEMPro and it seems to work, but it does not make much difference to the guiding performance. First world problems, I know, but does anyone have an idea about how I can tame RA when seeing is exceptional? -- jamie.amendolagine@... https://astropifi.blogspot.com/ https://telescopius.com/profile/james_amendolagine

I 3D printed a bracket that clamps on to the DEC axis and has a vixen shaped column on the western side onto which I clamp a 5lb ADM accessory dovetail counterweight. Purpose of this is to have the western side of the mount slightly weighted. When I had the mount perfectly balanced I would notice a bit of backlash while guiding so this is an attempt to correct. I’ll post an update of the guiding here once I get a clear night (yeah good luck with that) from this SoCal marine layer. Rainy winter -> May grey -> June gloom.

I was wondering whether anyone had any ideas what is going on with my guiding graphs or even if anything at all is going on with them. With PEC on or off, my guiding graphs look toothy/jagged. There are some areas that are smooth, but otherwise, it is a jagged appearance rather than the curved lines I see in images of other people's graphs. Obviously, if I change the scale these look much flatter. Would an overly tight RA worm gear cause this or could it be the result of poor seeing? I recently adjusted my worm gear and I have little idea of what is too tight. My unguided graphs look the same, so this isn't issue an issue with the PEC itself. Guided: Unguided: George

I didn't get anything last night, but here is a shot of the massive sunspot that is causing all the spectacular light shows.

My G11G seems to 'wobble' at the scope level and mount level and I am curious to know if this is the reason my PA is always off by 5+ arc minutes everytime I check it. My mount is permanently installed in my observatory and I noticed that if I do an extreme tightening of the ALT 4 bolts, it does help but the wobble is still there. I've been ignoring this for a while but having a hard time trying to understand why my PA is always off. My mount is on a 20" wide, concrete filled sonotube that is buried 5' feet in the ground with another 5 inches above the ground in my observatory. My pier is a PT2 and I literally was trying to rock that yesterday and using a digital level, there is no movement in it (it is an adjustable pier but I have not moved it in over a year and it is at its lowest position and has remained there). I have a SW120ED scope installed and an Losmandy RA extension tube and I have verified all bolts throughout the system is very tight. Any advice would be apprecicated. Hopefully the video I attached here (along with ALT picture) goes through.

I am going to disassemble my G11G off my permanent pier tonight and check and see if the bolt between the pier and G11G base is a little loose. I don't like the fact the whole assembly seems to wobble and my PA is always off by 5 arc minutes everytimeI check it. I believe the base of the G11G has a single hole in it for as mounting hole for a bolt from a pier. Is this correct? Drawing or picture would be appreciated.
