Re: Power Up

I power cycled and I did not get the Start menu this time either. I watched the screen during power up and it never showed the Start menu. Why is this?
Power Up

I have noticed that my screen after a power up where I did not immediately set which Start mode I wanted, seemed to have skipped that menu. Does it time out and sets itself?
Re: Resetting CWD

 

I think Michael was on to something re: some context needed

other mounts like ioptron have to be moved into cwd position and then you say "cwd is here"

with the Losmandy you do the opposite: set it at cwd and then cold start. The Gemini assumes the position at cold start is CWD

I agree about clarity, exactly does what does this part mean.? I've one ruler, or in this case spirit level.? How do I "slew" or even when do I "slew" to a "more accurate position".? After all, we know I must define CWD before the first star alignment.? After that alignment, this best measured and stored CWD value only affects the mount Limit operations and Parking, not further slewing operations.? So, I wonder when or how, without returning to the conditions before the first star alignment, does this "more accurate" part come about?

I don't think what you're asking for makes sense. In setting CWD you're physically putting the mount in a reference position (manual slew or loosen clutches and move) then by doing a cold start, it captures the motor/encoder position as the reference. You're defining CWD.? So by issuing a slew a position you've called CWD and cold starting won't do anything.? You're already there as far as it knows.

Thanks for all the replies. What I am specifically looking for is a way to slew to an accurate CWD position, then hit a button to simple reset it, that's it. That would be great.
Re: Resetting CWD

 

To request Gemini-2 to reinitialize the mount using the HC to control Gemeni-2 that would be MENU->MOUNT->Startup panel.? From the Menu the "Mount Startup" panel allows changing the defaulted startup mode and also contains a "Restart Mount" button which returns Gemini-2 operation to the mount initialization point.?

Placing the mount in the required physical position and then initialize to that position, remain separate issues.? But one can certainly power up, use the motors to slew/move to CWD and then initialize the mount (HC or remote).

Hand Controller Issue

 

Greetings,?

I've owned my G11G for about a year now, and it's been flawless for me.?

The other night I power on a usual and the HC goes through its startup and lands on the menu for warm start, cold start etc. Seems normal.?

Where do I go from here? Thoughts??

Hello Peter,

I like your curiosity and as I grew up with cheap and manual telescope mounts I have asked some of the same questions. Unfortunately I now have 2 remote control telescopes in my back yard. They do anything I want, but I rarely just sit alongside the telescope with a Star Chart and look at the skies.

To answer your question "is there a way to do this without a power cycle?"

Yes, but no-one does it, even your printer does a calibration power cycle. Commercial CNC machines have travel limits optical counters, encoders etc. They are smothered in high tech and need specialists to set them up.

I would see if you can get a tour of an observatory and see how they do it. Then, look at a local enthusiast setup and see how they do it.

My friend who does not have a Gemini 2 has to enter Date, Time and Location etc into his controller even before it will do its first GoTo as part of it's nightly calibration so he has to buy a GPS unit, I just take the Location off my phone if I am away from home, Time and Gate are always set on the Gemini 2

Have you tried to do a Polar Alignment Yet?

What plans have you made to find Venus and Jupiter in the daytime?

Happy to pickup the phone and chat techniques, or maybe we need a Tips and Techniques Forum.

For a closing question... Who has used the Setting Circles on their mount in the past 10 years?

Re: Resetting CWD

 

Yes - technically not a power cycle, but it does effectively restart the Gemini - it's much the same effect. It does work - you don't even need to loosen the clutches - just get it in the right place and reboot the Gemini. (I've done this remotely as well- there is a "Cold Reboot" function via the web interface).?

Without restarting/rebooting the Gemini as above I do not believe it is possible though.?

Yes on HC stop tracking ¡°sleep¡±, then release clutches fully, move mount axes to Preferred CWD maybe one at a time, ?retighten clutches. ? PRESS MENU/system/¡°cold start¡±

It reboots the ARM etc without losing HC coms and resets CWD.?


But never done it so do at own risk ?


Is this reasonable ? ? Probably not!

But the fact of the matter is, if using an ASIAIR you will probably never use MOVE on the HC anyway so setting it at a higher speed once for automating PA is a good solution for ASIAIR users. With the change in Gemini 2 L6 that adds rapid changes to the MOVE speed value it's not an issue just something that ASIAR users need to be aware of.??
