Hey guys,

I bought a used lx90 today. Havent had a chance to test it out due to real *BLEEP* weather but I'm super excited.

Is there a way to connect the scope to a computer? I would love to do the following two things:

1. Update Autostart software
2. Control the telescope using some software on my computer (if possible, what would be the best software, and connecting cable?)

Thanks a bunch!

- W

You can find the software needed (the new Autostar updater 5.9 and Autostar Suite 5.5) on Meade's Website under Customer Service. It's easy to download.

Regarding the computer connection -- Meade makes a cord which connects to the Autostar Handbox and an RS-232 (9 pin) serial port. The problem is that most laptops and computers these days use the USB 2.0 interface. So you'll need to get an RS-232 to USB converter. Meade makes both. Depending on the model of the Handbox, you'll need either the 505 or 506 cable (most likely the 505). Radio Shack and other computer supply houses make the serial to USB converter. Plan on spending about $100 total.

Software is another matter entirely. So far I've been using the package included with the cables (Autostar Suite). I'll probably upgrade as I become more sophisticated.

Unless you're really experienced with astronomy, get to know your scope first. Then go for the computer hookup.

I assume your computer does NOT have a serial port.

You will need:

this- http://www.scopestuff.com/ss_sma2.htm

this- http://www.scopestuff.com/ss_usbr.htm

and this- http://www.meade.com.../downloads.html
Autostar Update and Autostar Suite

You can update the firmware, tours, etc etc; and also control the scope using a laptop.

awesome! thanks Joe!

I was reading up some more on this, and turns out I might be able to have complete control/pictures without leaving my room, or without adding an extra camera:


I'll get the cable and try this out!

thanks again.

Waleed, if you are interested, I also have a simple tutorial on my website that shows the basics of imaging using a Meade DSI, DeepSkyStacker, Autostar Image Processing, and Photoshop. This is not one of those confusing deailed tutorials. Rather an overview that takes the beginner from capturing raw imags to final processing. Feel free to peruse it if interested. It's the 'Image Processing' link on my site:


And don't compliment Joe too highly. I heard his ego is already too big..... :-)

That's my astro-buddy Terry! He has a great web site, and takes wonderful astro-photos using a DSI Pro camera and an alt az mounted LX90 (no wedge).

If you need info on STACKING short exposures he can tell you what works best.
