Hi Tony To change the safety limits for your setup, you want to be at the scope. you slew your telescope to one side of the pier with your camera pointing towards the earth, and get it to within 1-2"

HI Warren welcome! my answers are inline below *I've never heard of TTL connection? The GM811G Gemini supports ST4 no problem, but also (and preferably) pulse guiding, where the guide camera

Moly greases are great in their place -- very high load bearings and sliding contacts. But neither the GM-8 or 11 have any surfaces that are that heavily loaded. In addition, the matrix that Moly

Hi all, New member here.? I have settled on the GM811G with HD tripod and have a few questions.? In no particular order, they are: 1. I plan to autoguide with my ASI120mm camera to the mount's ST4

I need to change my safety limits as the telescope does not slew to a given point in Carte du Ciel given the "Invalid DEC coordinate" error which I understand is a gemini ascot error message. There is

Marc True. They're expensive but you get sun reflective coatings outside and dew suppression rubberized coatings on the inside. Plastic inside alone would provide nucleation sites for dew.? Chuck

I use the MP50 on the spur gear. I find it keeps the worm wet and has a nice consistency. But nowhere else.

I found motorbike covers from ebay come in different sizes and shapes and work a treat. Telegizmo is niche and overpriced BBQ covers IMHO. These days every accessory that has the word "astro" or

It came from ebay, basically a battery box with a wire and flashing led, I didn't see a non flashing version but sure there would be.

I could only see the video when i .logged in to the forums that looks like it would work. is there a non-flashing version? i feel like i might get seizures looking at that for too long!

Hi all, this is the flashing led I spoke about a week or so ago for the Polar scope, have not had the chance to try it due to rain etc but hope it will work ok. hope the video plays ok

Bought a large reflective tarp (silver one side, blue the other), folded it in half with the silver side out and asked wifey to sew up the ends making a sufficiently large and inexpensive cover. Use

+1 for telegizmos covers I leave my scopes out 24/7 365, including rain and lately temperatures up to 118F (you read that right) and my scopes and equipment have weathered it just fine (pun intended

I'm trying to find a suitable cover that will work for the above setup, which measures roughly 40" wide and 46" tall (to upper tripod clamps) for visual and possibly 48" wide for the imaging train

Nice work Jeff As I recall, you did a major upgrade into some really long focal lengths, so getting even this far is a pretty big step forward Brian

After some feedback from Brian, I rounded up the proper cables for PHD2 and plugged them into the correct ports. I also readjusted the worm gear compression on the RA unit. Last night was the first

I want to use Carte du Ciel to control my Gemini. I first do a Gemini startup and confirm all coordinates using the GPS satellite attachment. So times & coordinates are correct pointing to Polaris. I

I've just used SuperLube (PTFE) on my G11. Too early to say but I am expecting it to be fine.

Thanks. I have some of those screws at hand so will try to find a suitable washer.

Thanks all, it might help if I spelt the name correctly!
