Subject: Re: Etx 70-90 Sent: Monday, July 25, 2005 11:17:24 From: Lance Browning (email@example.com) 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. Thanks, LanceMike here: A lot of work. See the article "Putting ETX-90 on ETX-70 forks" on the Helpful Information: Telescope Tech Tips page.
