Subject: Fork Mount Compatability

From: Andy Jackson (
I've had an ETX90-RA for six monts now.  I am VERY happy with it
optically but I am starting to get GOTO fever especially since I got an
LPI.  So, several questions for you...

Is the OTA the same for RA and EC models?  If so, it would seem to be
just a matter of replacing the fork mount / drive base assembly 

Could I use a FMDBA from an ETX 60 or 70 EC model? 

Finally, where could I look to find one?

Thank You,
A. Jackson
Mike here: Yes, the OTA is the same. See the Telescope Tech Tips page for some ideas on attaching to other mounts. As to where, eBay or perhaps even Telescope Warehouse (see the Astronomy Links page).

I have an ETX 70 and am thinking of moving up the range. Can you use the
tripod from the ETX 70 on, for example, an ETX90? I suspect the mounting
holes will be different in some way. 

In my short ownership of the EXT 70 I have found your site to be
required reading. Great work.

Mike here: Yes, you COULD use the ETX-70 tripod with the ETX-90 BUT you probably don't WANT to. It is too lightweight for the ETX-90; you would get way to much vibration in the views when focusing or even when just viewing. You need a sturdier tripod for the ETX-90.


Thank you Mike
for your knowlegable and very fast response.
