Quote:I would hope the JMI gears are acetal (Delrin) rather than nylon, it's a much more stable and durable material. Though I wouldn't think the stress on DSC's gears would be much.

Quote:I am considering putting digital setting circles on my Losmandy G-9 (GM-8). I mean push-to like Skycommander, not go-to like the Gemini system. Anyone using these? If so, what are you using and what are your thoughts?Thanks for any help

Quote:I will probably go with the Sky Commander. I called Losmandy and they are putting together an encoder kit for their mounts and they said it should be ready in a couple of weeks. I'll either wait for them or go with the JMI kit.
Quote: One last plug for the Nexus/Sky Safari combo. This is state-of-the-art planetarium software on a wireless hi-res tablet. The hand-held units used by Sky Commander, JMI and goto offerings of commercial 'scopes are so very 1990s: Quaint.
Quote:Be aware that unless JMI have changed their design, their kit does not use the 6 transfer dowels as shown on this Losmandy schematic. These dowels enable one to move the 'scope and still retain encoder positioning. I had to modify my JMI kit to accommodate for these dowels.
Quote:The Nexus system seems to be very interesting indeed - but cannot find that much GEM using it , at all...! Maybe it is only because it's still relatively new. But, I would say, just as good as Argo Navis or Sky Commander. I am tending to go towards push-to as I live in a very urban area and having motors running at 3am would wake up the neighbours..!

If you did without the gear cover it seems these "tranfer" dowels would not be needed and it looks like the JMI kits do not have a gear cover. Am I reading this wrong?
