Re: RA axis tight section
May not be relevant to this issue, but I seem to remember in the earlier G11 models the shaft is secured to the plate assembly with an allen screw. I had to re-tighten it once when I found as bit of

I'm in the process of cleaning/regreasing again, and this time noticed when reassembling that there is a definite stiff section when rotating the RA main spur gear by hand with the clutch moderately

Re: Losmandy GM8 periodic error
Hi,
Yes, I know the paper Michael made and that was the main reason I started modifying the mount. And I have to admit I love this part J Also because I have I friend with the same mount and we are

Re: Losmandy GM8 periodic error
Hi Catalin,
Have you read Michael Herman's document in the files about how to optimize your G11 mount? It is the definitive piece for the G11 and GM8 mounts! Shoot me you mailing address and I'll

Re: remote operation
Yes it can. I run my entire system remotely from my house. I use the G11 Ethernet port with a local router. My cameras are ethernet enabled as well as my focuser.
Works great. I can make all night

Re: remote operation
Anon,
Yes, it can be run remotely, however, this is a lot more challenging.

remote operation
I've got a G11 with NGC Max digital setting circles. I'm considering the Gemini system. I see GPS is available. Can it be run remotely? When it's cold I'd like to be able to keep warm and operate

Re: Losmandy GM8 periodic error
Catalin,
My experience was with a used (made around 2006 I recall - it has the 25
year sticker on it) G-11. I was the second or third owner. I think the first
owners bought it and did not know how

Re: Losmandy GM8 periodic error
Hi Catalin,
If you are capable of doing the mechanical work without damaging the mount and the mount ihows no obvious damage your GM8 should be capable of pretty good tracking. With any project

Re: 32s RA oscillation?
Hi Magnus,
What I am suggesting you might try is to loosen the two fasteners that attach the servomotor to the gearbox. Then slightly moving the servomotor around during a long slew and find the

Re: Losmandy GM8 periodic error
Your first big win will be very likely from the worm gear mesh adjustment, that's definitely worth doing. I got a large improvement on my mount just be doing that.

Re: 32s RA oscillation?
Hi!
What is the "sever motor pinion"? English is not my first language... and technical terms are a bit tricky at times.

Re: 32s RA oscillation?
Hi All,
I think the 32 second period is how long it takes for the standard Losmandy gearbox intermediate gear to make one revolution. You could try adjusting the servo motor pinion by loosening the

Re: 32s RA oscillation?
Actually, I found that it may be possible to open the gearbox. I replaced one recently, and the new one shows that there are 3 small hex screws, two about across from the shaft, and one at the bottom

Windows Update KB4056892 causes disconnect errors for Astronomy Programs
Windows 10 update KB4056892 (and we now know that KB4056898 for Windows 8.1) causes DCOM errors. This can keep Astronomical programs and drivers that depend on
