Who's Used DSC's With Their G11?

Hope this helps.

I like that the kit includes the gear covers too.

Once polar aligned, they worked wonderfully. I always had too much trouble figuring out and using Gemini, so I went for the DSC's. I'd do it again. (for me its mandatory to have the polar alignment scope option).

The other nice thing is that the Argo Navis unit can be ported from mount to mount, whereas your Gemini paddle is "married" to the G11 and other Gemini-compatible mounts. But certainly not dobs.
All told, however, the GEM market has moved decisively towards go-to, but I'm very happy with the DSCs in general and Argo Navis in particular.
AN's advantage over sky commander is that it can be used to compensate mathematically for pointing errors. So if your polar alignment is off it will figure things out. So will the Gemini hand paddle, by the way. But dsc-to-dsc, this is an important advantage.
Argo Navis also has the better menu, display, and user friendliness of the various systems.

I was looking at it from an availability / simplicity & power usage standpoint. That just fuels the fire.

The user manual is 228 pages. Eek! Lol.
Yes: it's a long manual. There are some "cheat sheet" workarounds in the FILES section on Yahoo! groups (argo_navis).
I would point out however the Argo Navis doesn't require you to use the complex options. You can do a one star alignment once you have it set up for your mount (which then stays in memory). To do a one star alignment you just turn it on, select ALIGN STAR, and point the thing at the star and zap it. You have to know the name of the star.
That's it, you're in business. For people with four inch refractors this is probably all they need.
Where Argo Navis gets complicated is when you want to build a model to correct pointing errors, and this mostly applies to GEMs. If you take the time to learn how to do that the process itself takes about fifteen minutes once you know how to do it. The pointing error model is a bit complicated because AN likes the user to have full control of what the unit is doing. I think the process of selecting variables could be automated. But the cheat sheets will tell you which variables to use (for quick and dirty setup).
The other systems with limited mount modeling capability, like CGE, basically worked because the manufacturer selected which variables to use. Still I must say I'm a little puzzled by it, I keep thinking that the computer itself should be able to select the variables to use and the variables to throw out.
Bottom line: once my AN is set up at night I know longer think about its pointing accuracy. There are no meridian flip worries, no re-synchs, just all-sky pointing accuracy. It's an excellent tool but a bit geeky. If you use it in the simple mode (like one star alignment) the ergonomics beat anything else on the market.

I finally got prioritized enough to order the AN system for my G-11. It shipped yesterday. Now to dig up the install PDF on Losmandy's site and join the AN Yahoo group! AN Manual is downloaded already.
I will try to follow up with a short mini review and some pics when it arrives.

I have never seen color on anything in focus including Jupiter & the Moon. The more I look through other scopes, the more I appreciate how good this one is. Lomo Ok4 doublet which SV labels as an APO, and from the in-focus views, I have to completely agree.

My G11 came without Gemini. I added a set of Losmandy DC & a Sky Commander. Installation was easy if you can read, use a screwdriver, allen wrench. Read the installation instructions, then read them as you do the installation. It has worked well once you got on target, well worth doing if you don't want or have used Goto. I had it on my LXD55, when it worked it was okay & have missed Goto on my G11. I've ordered a Gemini2 upgrade & it "should" be in this month. Goto or I should say ACCURATE Goto will be a nice change.

On a side note: my AN arrived today! 4 days to get from AUS to Arizona and clear customs. Wow! I wasn't expecting it until next week.
