Hi everyone,

My newly acquired C8 (HEQ-5-Pro mount with SynScan hand controller) is about to have its first outings. While I'm sure the basic GoTo controller included will function more than adequately, I'm interested in being able to drive the instrument via something with a bit more of an intuitive and user-friendly interface... i.e. some planetarium software on a separate portable computer.

Options I'm considering:

1. Netbook (Ubuntu linux) -> USB <-> RS-232 -> GoTo System

2. iPod Touch -> WiFi <-> RS-232 -> GoTo System

3. MacBook Pro -> USB <-> RS-232 -> GoTo System


Option 2 sounds cool, but the WiFi <-> RS-232 adaptor is not cheap ($164 USD) and while I am moderately impressed by some of the planetarium software I've downloaded for my iPod Touch, the small screen size makes it a less attractive option. The nice part would be not having to lug a "big" laptop out with me, in addition to the mount, the OTA, the battery, etc.

Options 1 and 3 are the simplest and cheapest as USB <-> RS-232 adaptors are cheap as chips (even Jaycar will only hold you to ransom for about $30 for one), but necessitate lugging a computer along. The Mac would provide the more bullet-proof option, however, my little Acer Aspire One netbook is smaller and lighter, but it's currently loaded with Ubuntu 9.10 (Karmic Koala).

So my questions are:

1. Has anyone out there experimented with using an iPod, iPhone or iPad to drive their telescope via WiFi?

2. What would people recommend as a good (i.e. stable, simple) piece of software for this purpose that runs on a Linux (Ubuntu) machine?

All comments, suggestions and ridicule gratefully accepted... :-)


Cheers!
Chris

...addendum...

The choice seems to be predominantly between Starry Night, and Sky X, on the Mac, and KStars under Linux. I've installed KStars on my little Ubuntu-powered netbook and it seems to run just fine, though as I haven't acquired a USB <-> RS-232 adapter yet, I can't test the scope-driving functionality.

I already have Starry Night Enthusiast (it came bundled with my copy of the "Universe" textbook, bought for an SAO course) but unfortunately one has to fork out for one of the "pro" versions to get instrument-driving capability.

Thus I will trial KStars on my netbook and see how it goes... if it's not quite good enough, upgrading Starry Night seems the better option.

Has anyone used The Sky X much?

Cheers,
Chris

i've used K stars on a linux machine & i found it a little clunky - you should add sky safari to your list (formerly known as voyager) from carina soft - i am running it on a mac & its iphone compatible

there is also skyfi - have a look in the iphone apps thread
