Not sure if Im doing this right via email so aplogies. Posted over on Cloudy that Im resurrecting a G11 Gemini thats been mothballed for a few years from my old observatory. Have it all cleaned up and

Much appreciated Mr. Duke! I'm retiring my Kendrick power supply and will need that 4 pin Amphenol to craft a cable. 90 degree = perfect application! For the record: I see nor hear any difference

Just a follow up in case anyone else in the future is looking for a power supply. I've had about 4 nights with the NEC ADP57 and it's working great. I bought a "Genuine New NEC Versa AC Adapter ADP57

Hello Chip, I appreciate your interest in this subject, thank you for your input. This mount overhaul process is new for me so experienced input is welcome. A couple of things, I bought this G11 used

Let's do the math, what did you change? If an assembly slips apart freely at room temperature it will be just as easy to reassemble at room temperature. If you had to resort to using a dead blow

Unfortunately, that was not my experience. The cleaned surfaces coated with a thin layer of assembly lube did not slip together easily. Even a couple of taps with a dead blow mallet did not make me

There is no need to heat the the worm wheel for assembly. As you experienced during disassembly they are machined to fine tolerances so if there is a bit of lubricant, the surfaces are clean and

Thank you for your advice. I also got some assistance from Michael Herman, he mentioned the same things all of you did. This is what I had to do. I cleaned the ring gear and heated it in the oven at

These part are machined to tight tolerances and even the slightest misalignment of the bearing ID with the tube will cause the bearing to jam on the tube. You will have the same issue with the worm

I would suggest moving this question to the Losmandy_Users group. They're also discussions there regarding lubrication, in particular with regard to ring/worm lubrication, that may be of interest.

Did you try to apply some grease to the post and the bearing? Just a tiny amount to reduce surface friction between the two.

Hello all, I know this is not a Gemini question, but I believe if anyone has seen this problem, they would be here. I have torn my G11 down to lubricate it and check the bearings. After giving a

I've got an older Gemini 1 with flat RJ45 RA and Dec cables that I'd like to update to curly RJ45 cables. I don't want to invest in a crimping tool, bulk cable and connectors for this one time job but

I asked Tanya about it and she said mine are the early high torque motors before the cooling fins were added. The previous owner used a 13.8V/5A Pyramid power supply and said it worked well, but I

I never tested or timed it but AFAIK Gemini slew speed is set by the Gemini under the "speed" settings and the encoders which look at motor speed and counts for position just let the Gemini know to

What kind widget are you using to go from the Gemini 1's RS232 serial port to BT? Why BT? I was using a Sky Safari SkyFi III Wi-Fi device to connect to just about everything over Wi-Fi. Basically if

BT makes virtual com ports that maybe out of the range skysafari can see. ? Or possibly it’s a skysafari setting -- Brendan

My Dob connects and the tablet okay. It detects and connects to GeminiBT, however Sky Safari does not see it. Perhaps a sign saying don't be lazy. Thanks for your time Brandan!

It’s possible that the tablet needs to be configured with Serial PortProtocol (SPP) mode. Since tablets normally connect to phones, music devices etc it may not have this mode ? ?I made a BT to
