My Gemini II Hand Control always shows Jupiter and Saturn as "pre-selected" and won't let me select them.? Who wants to view them anyway?? LOL The other planets appear fine.? ?Anyone know a fix?

Hi David, I’m not sure I can help much but, are you sure they are up at the time you want to observe them? Saturn is very close to the sun and rises close to sunrise. Jupiter is better placed but sets fairly early at night. Gemini grays out options that are not visible at the time so you can’t select them, I’m assuming this is what you are experiencing?

In any case, it’d be nice to know what you mean by “pre-selected”, as well as HC and Gemini software versions, just in case it actually is a bug in the software.

?

Let us know?

What is pre-selected?? Only solar system bodies that are up will be enabled.??

Verify your time (do you have Daylight Savings Time locally?) and / or if using NTP that your NTP server IP is valid and that your Gemini 2 has access to Internet service.? Also confirm your GPS coordinates are correct as well as signed correctly.??

?

If these things are correct and your battery is fresh you should be GTG.??

I realized that if you are trying this at night the problem is not the Gemini but the fact that Jupiter and Saturn are up in the day not at night right now.? So if as I posted.ylu have everything set correctly this is what the Gemini 2 is supposed to be doing.? Try it now in the daytime.? Jupiter and Saturn will be available to GOTO and the Moon and planets will not.?

I'm embarrassed, but I thought they were up!? ?I think that's the issue--can't select them for that reason.

Also on the hand control topic, I'm in Michigan and it doesn't seem to like the cold climate at all.? I've never had it fail altogether, but I have to press the buttons several times to get them to operate.? ?Is that just the nature of the beast?? Does using a stylus help?? ?Sometimes when I tap repeatedly, it starts talking to me in German.? Alles gut.? Ich kann ein bisschen Deutsch.?

Touch screens are not very fond of cold climates :). Using your finger nails instead of fingertips is a good option. Also a pen or an old style stylus (the plastic, pointy tipped ones) work in a pinch. Modern capacitance stylus aren’t very helpful but still better than gloved fingers lol

I'm fairly certain Jupiter is in the night sky currently, at least early, mid evening :-)

I'm fairly certain this is true if you live in the right place.? ?Not sure where the OP is located but in Saginaw by the time it gets to be almost dark Jupiter is an hour away from being out of view.? Most folks are just getting setup about that time.??

The HC is temperature sensitive for sure.? Have you tried to use an app on your phone like Sky Safari to control the GOTO of the mount?? ?Works great for this.?
