The ETX-80 is the same, as far as the AutoStar is concerned as an ETX-60 or ETX-70, so the 494 works fine with either. The 90, 105, and 125's are different, though, and the AutoStar knows that-- my 494 would not work with my ETX105-- a message appeared on the screen that told me I needed the 497 (I don't remember the exact wording, but that is essentially what it said). I suspect that you'll get the same message. -------------------- Tom Rutherford 10-inch f/6 Homemade Dobsonian (Cave mirror) 8-inch f/6 Homemade Dobsonian 6-inch f/5 Meade SN6 6-inch f/10 Celestron C6 5.5-inch f/3.6 Celestron Comet Catcher 66mm f/6 WO Petzval 2-inch f/15 Nippon Kogaku (my first telescope) assorted unassembled pieces and parts Edited by rutherfordt (10/11/08 08:43 AM) Post Extras:       yock1960 professor emeritus Reged: 06/22/08 Posts: 979 Loc: SW Ohio, USA Re: Will a 494 autostar work on a ETX90 [Re: Vars191]       #2692714 - 10/11/08 11:20 AM Edit   Reply   Quote Quick Reply   Did you check the 'Telescope Model' setting in Setup? If it's in there it should work. If not and from what Tom said regarding the 494 'knowing' it was attached to a 'wrong' scope, you may be out of luck. Based on a quick search and anecdotal info...it looks like it should work, but it probably depends on the firmware in your 494, whether the ETX90 is a known scope. Good Luck! -------------------- LXD75 GEM Orion Starblast 4.5" Imaging Reflector William Optics Zenithstar 66 SD APO Meade DSI II OSC Meade DSI III OSC Orion Starshoot Autoguider Televue Powermate 2.5x Discovery 6" Dobsonian Nikon Action Extreme 10x50's Gallery Post Extras:       Darenwh Pooh-Bah Reged: 05/11/06 Posts: 1224 Loc: Covington, GA Re: Will a 494 autostar work on a ETX90 [Re: yock1960]       #2694073 - 10/12/08 01:24 AM Edit   Reply   Quote Quick Reply   Depends on the model of ETX90 also. The RA version and origional version are not able to be used with any controller as they only have an RA drive, no DEC motor or control circuitry included with the scope.
