Yes, I googled it and the G42 has some good recommendations. With Pulsar controller and counterweight it lands a little above 6000 Euro. Do you have one yourself Jeroen?

I just read that Gemini is also introducing a new mount, the G53 with encoders on both axis and some kind of friction wheel instead of worm wheel. According to the advertisment the PE is about 10" in 40 minutes. No price yet though.

And there is also the Fornax 51 mount with a PE about 14", but they claim about 1" after PEC. Not sure about the capacity though, but I saw a picture of it with a 300 mm Newton in the saddle.

And an excuse to the OP for hijacking the thread

Gemini making mounts ?
Thought they making just the electronics.
Any info on this G53 ?
And strange to advertise PE in XX minutes.

The Pulsar software and its usability are definitely things that you'd want to research before you commit to anything..,

Of the three people that I know that bought G41 and G42 mounts, none of them ended up keeping them.

skybsd, one can also buy it with the FS2 controller if one has doubts about the Pulsar controller.

Lars, yes.

Tapio, there is some information in German in this link:
http://www.teleskop-austria.at/prod.php?tid=13&lng=de#goto-g53f-ge

The 40 minutes mentioned is the period for a full turn of the friction wheel. The PE of 10" is without PEC or feedback from the encoders. With feedback from controllers, they state a PE of about 1" or less.

As far as I can see, the text doesn't mention any weight capacity, but since it replaces the G42, I guess one can assume they have similar capacity.

Skybsd, not that I am in the market for this mount (at least for the time being) but out of curiosity, what are the drawbacks of the Pulsar controller?

From what I recall, the common theme from each of the three fmr G41|42 owners expressed disappointment that the software was not stable and was often inconsistent in operation..,

In the end, I think they each underestimated the baggage that came with a new system that was (at the time) under pretty frequent changes and updates.,

Regards,

skybsd

Hi Tapio,

A completely different company, Gemini Telescope Design, makes the G41/42 mounts. Thanks for the information on the G53F. I'm very excited to learn more.

I have two older G-41s that have literally been around the world several times over the last 7 or so years. One was severely damaged returning from China a few years ago and is waiting for me to install a new shaft coupler while the other is set up in the back yard. They've served very well indeed. I've yet to see better tracking from any "conventional" mount to date.

Clear skies,
Bill
