Spectacularly crisp images. Beautiful work! wrote:

Thank Brian. Yeah I don't do moon or planetary shots often unless something specific happens like an eclipse or occultation but the conditions on that night were too good to pass. I started at sunset

geeze Marc that is some incredibly sharp imagery. I imagine it was an exciting night! well done Brian wrote:

We had a one in ten years night in Sydney last week-end when the jetstream dropped to 1 knot on the whole easter coast. Got out quickly and captured frames on Jupiter, Saturn and kept shooting panels

Hey everyone, hope you all are doing well. Last night I had a scope crash and it seems to have confused my Dec encoder. I was looking for a way to reset the encoders, but did not find anything. After

Correct - angular momentum is I*Omega where I is the moment of inertia. For the simple case of a counterweight on the shaft, angular momentum is M*L^2*Omega where M is the Mass, L is how far it is

Hi Les, as I pressed the send button it dawned on me how to do it, you must have replied as I deleted my original post, thank you

Thanks Brenden, yes mine is 5v

Hi Bryn. Yes fault is in main PCB. ?It’s either a H bridge or failed motor encoder IC. ?The motor encoder IC Has embedded firmware. ?These are subject to common fails usually someone miss-keying

Heavier weights closer in every time – it’s the moment of inertia that gets you. David Sent: 02 September 2020 13:00 To: [email protected] Subject: Re: [Losmandy_users_io] Maximum weight

Thanks for the graph. To balance the scope would you use heavier weights closer to the RA axis to minimise moment of inertia or lighter weights further from the RA axis to reduce overall weight on the

Hi Bryn, So when the cable in the DEC socket on Gemini was connected to the RA motor, the RA motor ran uncontrollably? That does sound like a problem with the Gemini unit itself. Could be something

Thanks Brendan and Paul, So I swapped the dec cable to the RA motor and the fault transferred, so immediately thought that the cable was at fault. However, during various other tests, the fault stayed

Paul is spot on swap Ra motor to DEC and visa versa. Keep track of which part started from. You can remove the motors and run them on a bench to test. They don’t need yo be fitted yo test. if the

Hi Bryn, Continuous uncontrollable slew indicates that Gemini isn’t reading the encoder from the DEC axis servo motor. Things to try: - make sure the motor cables are not broken by swapping them. If

Dave the standard hand controller socket is here ( https://gemini-2.com/front_panel_pinouts.html ) for all versions of Gemini. I think the only difference for G1 is it’s 5V not 3.3v. This is the

Hi all, I hope somebody can help? I picked up a used GM-8 with Gemini 1 about 6 weeks ago. After finally sorting everything out with serial cables, weights etc and having tested it all indoors,

The counterweight should be adjusted to balance around the RA axis, not around the latitude adjustment. Leave the latitude adjustment alone. Loosen the RA clutch and rotate so the counterweight bar
