From:	Lance Browning (
I have the etx-70 that came with a black ota which I had bought from
meade's outlet store. Meade tells me that the electronics in the main
base is all etx-90 including the base ,mount and frame. This telescope
even came with the etx 497 controller. I would like to upgrade by
replacing the etx-70 ota with the 90 ota. What's actually needed to do
this upgrade besides just the actual 90 ota.


Mike here: A lot of work. See the article "Putting ETX-90 on ETX-70 forks" on the Helpful Information: Telescope Tech Tips page.
