Peter, J2000/JNow setting affects gotos to coordinates only, not tracking, guiding or meridian flips. J2000 is generally not needed for use with NINA and most other automation software, but yes, this

Paul, My poor addled brain finally figured that out. Currently, I use JNOW as there was an issue with there being an offset using J2000. Does this version of the driver fix that problem? Will this

You are selling an item that can be shipped rather inexpensively. So the best way to reach a willing buyer is with the mass market. Another is to watch the want ads on the astro sites. The 492 systems

Version 1.0.82 is not yet officially released, but available for testing here: /g/Gemini_ASCOM_Driver/files/Test Regards, -Paul

Where do I down load the 1.0.82.0 version of the Ascom driver? I can only fine Gemini.Telescope.Net (1.0.75.0).

There's no way for the ASCOM driver to tell PHD2 to stop guiding, but I can certainly add some checks not to accept guiding command during a slew. While I'm not sure that's what caused the wild slew

I becoming increasingly frustrated trying to execute a successful? meridian flip. Up until this point I thought I had a settings problem, for example setting the western goto limit value correctly.

Maybe the "stop guiding when slewing" under PHD2 doesn't work because it is "too late" and gemini already got some kind of simultaneous mixed-up command.? I wonder if via ASCOM there is a way for it

I've bought and sold on CN , Craigslist Ebay and Facebook Marketplace.. (Not just astro gear)? Ebay seller fees are expensive (10 to 12.5%).? Although you can do a local pickup only sale on Ebay,

Hi all, I've finally gotten around to testing the performance of my G11G and everything wenty great except for some pretty erratic behavior in the RA axis diring guiding. I used all default settings,

Hi Alan, Peter is going to list his better replacement parts. (He also has found an 80:1 gearbox that is not marketed by McLennan..it comes from vendor RS Components. ) To get to the ring gear: On a

How does one get to the thrust bearings? What's the source and part number for the encoders? What's the maximum slew rate with the 1024 encoders?

Nice work, all! I had a long deep discussion with Peter this afternoon...(he bought a used G11 mount that had belonged to a buddy of mine in San Jose). Conclusions: 1. His DEC was a problem but now

Here's a pic gearbox side.

I experimented with some success with rigid aluminium couplers on an original OPW design. I bored both ends and precision fitted for my DEC paying particular attention to concentricity and tolerances.

I think if you can get to the bottom of your puzzle it will help others know what issue to look for. *** Seriously?? Even an idiot like me knows the answer to this.. And even your text based drawing

Thanks for the feedback and advice. I'm in no hurry - perk of being an astronomy professor is that I just get to have three setups for class instead of two until it sells. Shipping for both (this is

Seems good to me.. Either be patient (and edit the ad to keep it near the top), or drop the price to a "priced to move now" price, would be my suggestion.. .ie it depends on how fast you "need" to

Peter, Glad you were able to make a solid connection between motor and worm. McMaster is a super supplier and you can find a whole lot of specialty bearings connectors, gears, etc. I have used them
