Hi, I am requesting links to sources for the cable for connecting the Gemini2 serial port to USB with FTDI. I don't mind connecting 2 cables together to make one, but it is difficult to know which cable (like on Amazon) that is correct pinout that works. I saw the nice pinout diagram on Losmandy website, but still need help. Many thanks! Roger

Hi Folks, An official new version of Gemini firmware Level 6.1 and Hand Controller firmware v1.63 are now available for your Gemini. A few ways to update to this version: 1. Use GFU app. When you launch GFU, it will automatically suggest an update to L6.1. Use the default settings to update all the appropriate files, including some web pages and firmware. Double-check that the correct IP address is set, Gemini is turned on, and press Start: 2. Download and copy all the files directly to the Gemini SD card, from zip archive here. Make sure you copy the folders as well as the .bin file. Don't forget to flash NewGem.bin file from the Gemini web pages after copy. 3. Individual firmware files are also available, if you need to update just the firmware (this will not update any of the additional files, such as web pages): Gemini L6.1 firmware .bin Gemini HC v1.63 firmware .bin Here are the changes in this version from the previous release: HC: Show time to limit on the main screen, when time remaining is less than 1 hour HC: Checkbox to invert the direction of gearboxes in Mount->Gearing (for McLennan gearboxes, for example) HC: New page added under Mount->Flip to enable/disable and to configure meridian flip points HC: Fixes screen brightness reset to 100% after restart on home page HC: Fixes the Allow Speeding Up option not selectable MU: Provides for better brightness synchronization with the HC MU: Adds flip point configuration to Gemini web pages MU: Adds serial commands :HCx to change HC settings MU: Enhancements for PEC precision, drift removal Regards, -Paul

Hi ASIair users.... This is a reposte in hopes of getting responses related to USB connection. I am helping a friend set up his recently purchased ASIAir Plus and G11G w Gemini2 (which I sold him). He says the ASIair will not recognize the mount via USB. I don't know which cable he is using, and will see him this week. So I ask: Is there a proper sequence to startup and get connected and ready to do a Go To. Assume the mount has been levelled and is polar aligned. I always liked Cold Start w CWD: --- Everything powered off: --- ASIair physically connected via printer cable to Gemini2 control box. --- Mount is in CWD position. --- ASIair App (on Galaxy S9 turned off) If the ASIair will not recognize the USB connection to the mount, then what should I try? Change the power up order? When I had the mount, I used Serial to USB with FTDI, and it connected to my laptop nicely. I think there was a FTDI driver. Is this a back up option to try, and still using ASIair (not a PC)? Any other option, ie LAN? Many thanks for your advice! Roger This is the control box:

I’m looking to buy a Celestron 9.25 edge for my multi purpose scope. Just getting back into the hobby, and my interest are visual observation of lunar, planetary and DSO. I am interested in possibly getting into imaging further down the road and want to make a wise investment in my mount choice. I don’t want to go any bigger scope wise, maybe a refractor or two. Looking at the second hand market right now and there’s some nice g811s out there that are within my price range. I know the g8 was designed for the C8 and the g11 for C11, which leaves the 9.25 in the middle. If a g11 came up in the price I was looking for, the choice would be easy, but will the g811 be enough for the 9.25 when it comes to both visual and imaging? I keep getting conflicting opinions about whether this will be a good combo or not, and of course I could alway put the g11 dec on later down the road. thanks for any advice

So, I've been doing more testing. I have N.I.N.A set to use telescope side of pier. I have Gemini set to Report the pier side I am imaging an object in the east (so the scope is Pier side west). However, In my N.I.N.A logs, I see "True Telescope SOP=pierEast" when the scope is clearly pier side West. Given I'm in the southern hemisphere, are there some settings I need to update in Gemini? I use a GPS receiver to get the coordinates (which Gemini connects to) so it definitely knows where in the world it is. -- Thanks and Best Regards Neil

I have been mostly using my month old G11G with NINA, but started trying the ASIAIR this week. Overall, going well and getting good subs. But there are quirks that I would fix if there is a way. 1. moving the mount. I find that I need to power cycle the mount with the app running before the app thinks it can move the mount. not a big deal, just have to remember the order. Starting the app with the mount already up and running hasn't worked for me so far. 2. GOTOs generally happen, but the behavior in the ASIAIR app's sky atlas isn't reliable. Sometimes it seems to wait for moves that the mount seems to have completed. I stop the slew and tap the goto button again and it figures it out. 3. guiding is pretty good, last night running well below 0.4" but occasionally when I first start up guiding DEC will run a bit wide back and forth. About 10 minutes or so. Recalibrating and starting over tends to clear that up. I am not manipulating any settings. I also fuss over the DEC worm. I am using machine tools to measure how much back off the worm gets and try to reliably tension the spring holding it down. Anyway, things like that. If anyone has any tips on using this mount with the AIR I would love to hear them. I do prefer to use NINA, PHD2 etc. most of the time but sometimes a simple setup is nice.

A quick test shot of C/2023 A3 Atlas Comet I did with the telescope. 360 1 second shots tracking on the comet with Small and Solar System Objects.

Folks, Comet C/2023 A3 is set to make a spectacular appearance in the Northern Hemisphere in the next few weeks: https://skyandtelescope.org/astronomy-news/get-ready-for-comet-tsuchinshan-atlas-the-best-is-yet-to-come/ It'll pass near M5 globular cluster on October 15 if you want to try to capture both in a wide-angle view. If you use the ASCOM driver with your Gemini L6, you can locate and track the comet using Func->Small and Solar System Objects by entering C/2023 A3: Or use a planetarium software to find it. Detailed orbit elements are also available from JPL: https://ssd.jpl.nasa.gov/tools/sbdb_lookup.html#/?sstr=C%2F2023%20A3&view=VOP

Just with in the last 3 weeks, I have issues with the G11 RA and Dec motors (I think). Even if the hand control is set to slew, both motors move the telescope very slow. The mount was powered with 110 v I use an Asiair to control the scope so initial I thought that might be where the problem was (Don't know why but I though I would check). Disconnecting the AIR did not solve the problem. The G11 was purchased 9 years ago and has worked perfectly up until now. I don't know where to start. Any suggestions ? Thanks

I picked up a G11G on Cloudy Nights from 2015 with HT motors (non-tucked-in), HD folding tripod, Gemini-2 level 5 and polar scope, no SLW, for $2100. The mount looks like new, it was well taken care of by the previous owner. I upgraded the Gemini-2 to level 6, got a PicKit3, flashed the motor controllers with v3.0 and checked the 4x checkboxes. I just tried it with Ekos, everything works beautifully. I'll try to get a first light tonight. The previous owner loved the mount, but he had moved to a place where he had no good space to set up a telescope, so it didn't get used. I picked it up from Arizona with a detour to visit an old friend, almost 23 hours of driving without air conditioning but well worth the drive. My current mount is a G11S from 2018 with OnStep. One reason for getting the new one is to compare a standard Losmandy with servo motors with OnStep that uses steppers. Comparing the price of Gemini II with motors with the $2100 that I paid, I think this is an excellent deal. I can always sell it easily should I want to. Another reason for getting it is to have a more "mobile" mount. I have an observatory that is a converted lean-to shed against a wall next to the kitchen area from where I can only see the Southern skies. I noticed that I could see most of the sky including Polaris from the patio in front of my kitchen window. Since I don't like to move the mount in my observatory to that spot and back all the time, it is nice to have another one. It is also handy for star parties. I got a Telegizmo cover to keep it set up outside for New-Moon weeks.
