Subject:	ETX-70AT Circuit

From: (
do you know where I can find the circuit diagram of the ETX-70AT drive
circuit? I am trying to add bigger DC motors to drive my 14inch with the
electronics of the little Meade.

Kind regards,

Markus Fankhauser
Mike here: Don't specifically know where you would find that but check out "Steve Bedair's "Go To" Mounts (Autostar info)" (link on the Helpful Information: Autostar Info page) and the Roboscopes Yahoo Group ( Also, there is the "More Schematic Information" info on the Autostar Info page; it shows the ETX-125 board, which I would suspect is somewhat similar to the ETX-70 board for the drive electronics.
Subject:	I have a question about astrophotography with the etx 70

I wanted to know what would be the best way to do astrophotography with
the etx70. I was thinking that I would use a digital camera but I am not
sure which type of camera I should buy, and what accesories I would need
to get. Please let me know
Thank you
Mike here: You can use a digital camera or a webcam or one of the lightweight (like LPI) imagers. You will need a lightweight camera unless you add some counterweight to the telescope. For more on astrophotography, there are lots of tips and examples on the Helpful Information: Astrophotography page. Also, keep in mind that for long duration astrophotography you will have to mount the telescope in polar mode (which the standard ETX-70 tripod won't do).

Once again great website.
Does the etx 60 and 70 fit on the 884 tripod w/o an adapter?

Mike here: It should fit without an adapter.

Mike here: The objective lens is glass. For comments on the ETX-70 see my report on the Helpful Information: Buyer/New User Tips page as well as comments from others on the Helpful Information/User Observations page. Keep in mind that the ETX-70 is a small aperture, short focal length refractor. Light pollution filters typically work best with larger aperture telescopes since they reduce the overall brightness of the image reaching your eye.
