Hi Jeff, Wow...your experience with that longitude - sign triggers a few other things to watch for: Yes....the East/West longitude entry is confusing. The unit boots up and describes E or W longitude.

Unless of course there’s an external power supply for the camera that supplies all the voltages and only needs a 12V supply. D. Sent: 27 August 2020 06:25 To: [email protected] Subject: Re:

When it got dark I tried some modeling. I don’t know the names of hundreds of stars but I know Dubhe is not hanging around the northeast at ten pm. I went back and double checked all the data I had

No it won’t fit, and it would NOT work even with an adapter. The camera requires +12V, ground, -12V and +5V – see appendix A2 of the user manual for the camera The power output of the G1 only

Hi Tom, If the worms don’t turn freely, you may need to clean and regrease the mount. Not just the worm and the worm wheel, but possibly also the needle bearings inside the axis. Are the worms

Thanks, Michael. I have already experienced the collapsing leg thing. So far, the one thing I prefer about my CGX-L mount is the tripod legs can be locked with minimal effort. Last week when I mounted

Thanks, Brian. I think I have the worm gears set at a nice compromise, not too loose, not too noisy. My goal was to get a mount that was sturdier than my Celestron mount so I could do some autoguiding

Wow. Great setup. I'm not used to seeing a Titan RA axis. A few things to consider: Be sure your knobs holding the tripod sections in place are quite tight. My C14's weight was slowly collapsing one

Good luck Jeff! that is a monster scope, hope it goes well -- Brian Brian Valente portfolio brianvalentephotography.com <http://brianvalentephotography.com>

I am all set up and ready to go. For the last week, fires in California and Utah have made seeing anything an exercise in futility. Today, the skies have been blue, instead of brown, and the clouds

I recently took my G11 out of storage after a few years of moving around. I found that the connector at the RA stepping motor was broken and decided to upgrade to a Gemini 2 goto servo system. After

Thanks Paul. Clarified the question. Luis

Hi Luis, You can't use Gemini power for your ST-8XE. The camera requires a number of voltages that are not available at the Gemini power connector, such as +12v and -12v, as well as +5v and a ground.

No. My question is not about autoguider connections, is about the electrical power supply. The box has two power connections. One "in", for electrical power supply of 12 V to the box. Next to it there

I have certainly had mounts with far more play than what I have now on my C11T. I have only recently gotten into autoguiding. Since I have been using my SCT’s with long focal length, even with a

The guider port has six pins, Pin 1 isn’t connected, Pin 2 is common. I assume you want to connect the camera as a guide camera? In which case the guider port is the one you want to use. Be aware of

Is it possible to connect SBIG ST-8XE? directly to outside port of the box? Gemini 1 throuht a cable din 4 pin or 5 pin? The inside power of the camera has 5 pins, the outside port of the Gemini has

JoAnn, Hi. There is a nice video on using Arduino to control a dc motor+encoder. Since you don't need acceleration and position control all you need is to control speed that makes it pretty simple to

update: I have found an original stepper motor from a group member. Thanks!

Hi Ron. I think you have the concepts. Another useful thing is: you can work on testing this in the daytime. Keep your scope and finder scopes optics fronts covered up so the sunlight won't overheat
