Re: Modeling mount

 

Thanks Michael,

1.????? How does I save the model to my PC? I usually Warm Restart with the hand controller deluxe and synchronized some stars and not realized the aligment of these stars because I did it in a previous session and the mount put the star almost in the center of the camera ST-402 (FOV of 8.9 x 13.4 arcmin). After, I connect TheSkyX Prof to find the stellar objects that are not in the Gemini catalogs (asteroids, small stars,¡­) and works with the camera, focus, etc.


2.????? My small observatory is in the mountain wihout internet. For the correct time I tried to connect the PC with a GPS through Geminitelescope.net and gave the correct position, time and altitude. I don¡¯t? know if these data collected by Geminitelescope.net is transmitted to the mount that are a little difference of the data that appears when I warm ?with the hand controller (position, time), and cause or not a disturbing to the mount . For this reason, I¡¯m afraid to control the mount with the Geminitelescope.net.

Luis,

In theory, once you build your model, you should save it to your PC and not need to ever cold boot again.? Only do warm boot to load in the last model saved inside the Gemini1 SRAM chip.

I say save it to your PC because if your backup battery dies, the Gemini 1 will lose the settings.
You can then upload the saved file after changing the battery.

Be sure to turn off settings in the Gemini.net applet that can affect the model.
That is on the advanced panel, upper right checkbox for "Synch performs additional Align".? You don't want that!

Then, just Synch on a known star every time you do the wam boot. ?

And always park your system to a known position like CWD. ?



That's the theory. ?

In practice:

Some programs like Plate Solver programs do not know about the Gemini model and using both is reported to mess up pointing.? So if you are using plate solving, after the first Synch, ?try leaving the Gemini model at all zeros.? See if that fixes the issue. ?

Sometimes my model parameters are messed up. Perhaps I added a bad alignment point.? Or some other thing has happened.? In that case, I build a new model.

There is a chip in the Gemini1 made by Epson. It is called an RTC real time clock chip.? Some people have said that can lose or gain time and so you must reSynch your time.? There is a simple way to do that in ,... I think it's on the Telescope panel. ?

?

Making a good model:

The manual says: add 3 align points on one side of the meridian, then add 3 on the other side of the meridian.? That is, do 3 align points either East (or West) followed by 3 on the other side West (or East).

Have fun, and hope your system stays Aligned!

Best,?
Michael

I suppose that is not a true new topic about the Losmandy mount: how often is advisable to realize the modeling of the mount? Every time when I open in warm restart, only warm or could start? My mount is a Losmandy G11 Gemini1 level4 in a permanent pier.
