Robert, There are two things I don’t understand about what you say. 1) Do you align the main and finder scope before doing this? Is so, then once an object is centred in the finder it should be

Geoff, So many things to suggest here for AP: -Go to the https://gemini-2.com/ website and read as much as possible to get acquainted with the mount controller -Go to the Losmandy channel on YouTube

Nice testing work, Nick. If you turn your mount head upside down, you will find it's serial number stamped there. The Losmandy company can tell you when it was produced. As you have the original steel

Thanks for the input! Luckily I had clear skies last night and tonight so I will give an update on where I at. Last night: I had 3 separate unguided runs using PHD2's guiding assistant which I was

Hi Nick, One of the better qualities of SuperLube is the low viscosity even when extremely cold, additionally it won't run all over when hot and get on your clutch discs. This helps with smaller

With my new GM811G, I have been working through setup details. When the scope came, we had three clear nights and I was able to be out, getting familiar with the new mount.?I love it!! My experience

Robert, Nice tip. I'll bookmark the site for use at home - I can't use it in the field but it is nice to have the option at home. The way I have gotten around this problem is to use a flip mirror on

Eric - Many thanks for this. A nice addition to my small, but growing trove of useful Gemini documents! Ed

Hello - I do astrophotography on a Digital Drive G11 - one problem I have had in the past is that if I use the finderscope of my telescope to find a bright star, then centre it in my main telescope,

Thanks for the response! Weather permitting tonight I hope to get a good hour+ worth of unguided data (8min periods for GM8) for PE Analysis, I was mostly concerned with all the sharp spikes but agree

Hello Nick - have you measured the periodic error of the mount - you can do this by running the Guiding Assistant for 5 or 6 turns of the worm (I have a G11, whose worm turns in 4 mins, so if you run

Ed, The comet tracking reference Brian provided above is for Gemini 1. Gemini 2 uses a different clock so the calculations will be different. I do not do comet tracking, but have a look at the

Hello everyone! I'm a relatively new owner of a used GM-8 Gemini 1 with the LW tripod, steel worm (not brass), and original worm block (not OPW). Also I have the old motors, not maxxon or tucked etc.

Thanks for digging a bit on this Brian. The reference you sent refers to the serial line protocol, which I investigated and it definitely suggests the command set for Gemini supports this if you know

Hi Geoff, I have never extended my HD tripods legs. And the stability is still awesome. About the only place the 12EX might not be a good idea is if you were using a Newtonian Telescope for

Bit of fun adding RGB color to a duo band mono luminance shot with a QHY9/FSQ106N. Technically the duo band is 34nm Oiii and 12nm Ha emission lines. I don't have any Ha/Oiii channels but had some RGB

Hi Ed, this page may be interesting to you, particularly the section on Coordinate Controlled Tracking. Looking at the Gemini interface, it's changed a bit so now you enter the delta RA and Delta DEC

Sonny, Have a Q about those 12" pier extensions... do you - or do some others - ever leave your tripod legs retracted as you use a 12" extension? I have thought of that as I have moved my observing

The Gemini ASCOM driver (and the ASCOM standard) supports setting variable tracking rates. It's entirely possible for software using ASCOM to set the Gemini divisor programmatically, so it's really

I’ve finally settled on the standard one leg to the north and the Gemini unit to the south (under the polar scope). Having the Gemini off to one side just bugged me aesthetically. It looked
