15 volts at 3 watts??? That is 15 volts at 3/15 amperes = 0.2 ampere, not enough amps to power the mount when it's slewing.? Or have I misunderstood?

Idea for next model of Gemini:? Volt and amp meters on the front panel.? That would make it much easier to troubleshoot a lot of problems people have.?

I tried using a usb-c to barrel jack 15v adapter, and it seems to work with my gm811g.?
I have a small power bank that supports 15v at 3w. It seems pretty convenient for my visual use, but I haven't heard anyone mention these before.
Any thoughts?

Hi Jeff,

Most likely some Gemini setting is entered incorrectly. What version of Gemini are you using, and what level of firmware? Do you connect your PC to the mount before doing that first Goto? And is the star within a 5 degree field of a finder, or even further off??

The most common errors are with:

1. mount type set in Gemini
2. date and/or time
3. timezone
4. geo location
5. large polar misalignment

Jeff,

I know daylight savings time can be a pain, been there done that too.? Anyway, check this video out, at least the first half about 8 minutes of it.? It goes through set up info.? There's a website that gives you accurate time zone offset info.



I hope this solves your problem.

Joe

The crucial question:? How far is it off, and in what direction?

I am not sure whether it’s a daylight savings time issue or what. When I put in all the data including gps location, local time, and time zone, my mount doesn’t go anywhere near the calibration stars it’s supposed to go
to. I have tried changing to a fresh battery in the little back box, but that didn’t seem to change anything. If I do big slews to where the stars are supposed to be I can eventually get things working, but it takes a lot of time to get there. The setup at my dark site is complicated enough without having to trouble shoot my mount every time. My Celestron mounts will ask for standard time or daylight savings time specifically but my Losmandy doesn’t. I?rarely have those issues with my Celestron mounts so I have been using them instead, but it would sure be nice if I could figure out why my Losmandy has become difficult to set up. Sometimes I just need my big G11T
for my bigger SCT’s when I am imaging.

Hi John,

Long time no see! This heen reported a few times and often the card reseating resolved the issue. If you can still get into the Gemini 2 using an Ethernet connection and the Gemini says the battery voltage is over 2.9V the battery should not be the issue. But if you open the Gemini 2 face plate up I suggest installing a new battery just because the battery is at least half way gone and batteries are inexpensive.

Be sure to replace the battery correctly or the battery will likely die sooner than later. This is also import to follow because? in some cases the Gemini 2 controllers can be damaged. This issue is due to a design flaw discovered in the NXP ARM processor chips used to power the Gemini 2 controllers..

A word of caution on opening the hand controller, be careful with it. By many accounts they are easy to damage when being opened.?

John,

You may also want to try to reseat the SD cards in the Gemini 2 and the hand controller as well. They can get jarred loose and won't do their thing. In the HC, the SD card is a bit harder to get at and you will need to carefully unplug the long multi-pin connector of the touch screen to get to it, after taking out the 4 screws that hold the outer plastic case together. Hold the connector at the far ends and slowly wiggle side to side to remove. In case you have not removed these before, the SD card is held down with a metal clip which must be slid down and flipped open before the card can be removed.

Good luck,

John

Sounds good!

No guarantee,? but I start with the cheap and easy first.? Also, it is easy to over look.

Hope it works.

Joe

Thanks Joe, I'll change the battery tomorrow.

What about the battery??? It is in the metal black box of the Gemini 2. ? My handset, came up in the German language before I changed the battery.? It was a little over a year old too.

Joe

Greetings,

Thanks!

It is my pleasure, thank you.? I discovered this stuff during covid, and out of China, this stuff is relatively CHEAP!? It's all about looks and versatility.? There are still a few items I need to add, and I might do some closeups of the parts on my scope for clarity.

Bob

Bob I also wanted to say kudos. I believe your wiki is the first on this forum. It made me realize what an underutilized tool that is. The wikis are editable by all in the group and your post is one example of an information share. I know Paul and Rene and others put a lot of effort into Gemini-2.com and we should not be all sitting around waiting for them to update it for Level 6. Your wiki should be an inspiration to all who have useful information to take the time to sit down and write it out for all of posterity.?

thank you.?

Brendan,
Thanks for the thumbs up.? It's hard to make custom brackets and make it look good without some serious tools.? Hopefully these gadgets will help keeps those scopes out here looking professional.

Bob

Sone really good ideas there Bob. I’ve made so many alloy one off bits and I can see how camera support is so much easier less flex. ?Really is multi use hold everything.?

well one attaboy from downunder?

cheers

Based on the interest in mounting systems for mounting various accessories, including counter weights, as discussed in the topic "Balancing Scope", I have created a WIKI to describe some of the various mounting systems I have used to add and mount various gadgets and capabilities to my scope.

The WIKI is titled?NATO Rails & Clamps and other Telescope Accessories Mounting Systems.

Feel free to provide feedback.

Bob

With the below mod I'm able to balance my Dec axis. The 3rd axis counter weight balances the electronic focuser, 50mm finder scope and the Star Surfer on the opposite side of the scope.



I replaced the 5 lb counter weight knob with a Losmandy Tripod Knob. It has a 3/8" TPI 16 through hole. The shaft is a 3/8" aluminum rod with one end threaded (3/8" TPI 16). The black counter weight is from my Star Adventurer.??

I got some PMs regarding these accessories.? So, continuing this thread, I put together a WORD doc (in PDF) with more information and some pictures of the individual components.? I might turn this into a WIKI page.? In the mean time, attached is the document.? Feedback is welcomed.

Bob
