Hi i have a ext90ec and was curious if there was any alternatives to the autostar system such as somehow hooking the telescope stright to the computer and useing some sort of software.

You can use either AS to control your scope via PC or Cartes Du Ceil.
Both programs work very good.

Yes you can use either the AS system or Cartes to control the scope via the RS232 port .
Your laptop will need a rs232 port on it.
Connect the cable from the scope to the PC and set the com port and connect.
Yu will be able to use the PC to control the scope.
You can slew the scope via the PC.

To answer the original question: you DO REQUIRE AN AUTOSTAR
to control any of the ETX, DS, LXD55/75 and LX90 systems.

The 497 Autostar has the rs232 socket as an integral part,
the 494 Autostar requires the purchase of a 506 cable/converter to
add an rs232 socket as a peripheral on the AUX bus.

Only the LX200gps (and RCX400) have the Autostar II (and rs232 socket)
built into the base of the scope, and hence do not require an external "autostar".

From an engineering standpoint, it is -theoretically- possible to replace
the ETX's Autostar with sneaky programming on a PC to wiggle parallel
port pins to created the 3 pairs of clock-and-data signal sets that the ETX
motor cards are expecting to hear.  Very, very, few have even managed to
get one or two instructions "understood" ("stop" and "go", but without
feedback), and none (to my knowledge) have managed to "replace the Autostar".

Meade's patent 6,304,376 actually describes the protocol, and you can take it
from there....

have fun

Have you heard of KStars?

http://edu.kde.org/k...screenshots.php

It's a free, open source astronomy package for Linux and the KDE desktop
Here's a list of telescopes that you can control via this program.

I'm going to try and control my ETX60 with it.
