Subject: etx70 guildscope Sent: Wednesday, June 25, 2003 19:43:51 From: ARSASTRO@aol.com I have a etx70 that i would like to use as a guildscope do you know or could you direct me to a link that shows me how to remove the ota from the base its a old scope so no warranty to worrie about. Regards AndyMike here: Since I'm traveling I don't have access to my ETX-70. But if it is like the ETX-90, there are four hexscrews (two on each) on the tube adapters. You can see more on the removal of the ETX-90 OTA near the bottom of this page: http://www.weasner.com/etx/90ec_comments.html.
Subject: ETX-70AT won't move vertically up under motor power, but moves down fine. Sent: Monday, June 23, 2003 18:33:51 From: firstname.lastname@example.org (Greg Nuyens) I just bought an ETX-70AT (the bundle with the field telescope that you recently described) for my son's 10th birthday. We're both neophytes, so my question may be just ignorance. The telescope horizontally slews just fine, but vertically (whether using cursor keys or GOTO) it will only move down. Looking through the eyepiece, it is clear that the motors start to move it up (maybe 3 degrees) then it stops. I have adjusted the Declination lock to "hand tight" but am nervous to tighten it past there. Reading other posts on your excellent site, I was also wondering if power could be an issue? I put new batteries in it, but haven't tried swapping them out. Any standard approaches? Thanks for any help, GregMike here: Doubtful that battery power is the culprit. If you unlock the altitude axis completely, can you move the telescope tube up and down freely?
Subject: ETX 70 AT different versions Sent: Monday, June 23, 2003 06:42:27 From: Ljubo.Juvan@adapta.si (Ljubo Juvan) I'm thinking of buying ETX-70AT (my first telescope). I noticed what Gary Clayton asked, so if this helps in any way (found it on a pricelist). The other versions are the same scope with additional equipment: ETX-70AT Astro Telescope ETX-70AT-E Astro Telescope with Electronic Eyepiece ETX-70AT-SB Astro Telescope with #882 field tripod and #124 Barlow Lens ETX-70AT-SBE with #882 field tripod, #124 Barlow and Electronic Eyepiece ETX-70AT-S Astro Telescope with #882 field tripod Thanks for the Mighty ETX Site!

Subject: ETX 70 AT different versions Sent: Saturday, June 21, 2003 02:12:15 From: email@example.com (Gary Bryce Clayton) I am thinking about buying a 2nd hand ETX70 though EBay, it is marked up as a ETX70AT-SB AUTOSTAR and includes the JMI NGC Minimax computer, are there different versions of this scope as this one is located in Singapore and would be shipped to the UK if I buy it. Many thanks Gary ClaytonMike here: The only different official models were the EC (Autostar optional) and AT (Autostar included). It is possible that models sold in foreign markets had different designations. I'm not certain why the Minimax is included since the Autostar performs the same function.
Subject: Scope comparisons Sent: Wednesday, June 18, 2003 18:31:43 From: "Lynn Laux" (firstname.lastname@example.org) This is not for me but for a colleague of mine who is interested in possibly getting an ETX. He saw the ad for the 70-AT on the back of a catalogue that the Astronomical Society of the Pacific sent out ($249). If you had to choose a scope that a student could use with virtually no tutorial (except maybe a little common sense): which would you recommend: the ETX-90 or the 70-AT (or maybe even a NexStar 80GT). My colleague is the astronomy teacher for our high school and also runs the planetarium; however he has no real amateur astronomy experience (he would be a complete newbie), and really can not identify many stars in the REAL sky. I am desperately trying to help him out but he seems only to want the cheapest scope; I keep telling him you get what you pay for, and that there is nothing more frustrating than a cheap scope. I have also repeatedly told him to email you regarding the ETX series, as I know very little about them from personal experience. Most amateursin my club have the big guns....the one gal who has the 70-AT never uses it because of the knobs and disappointing views. In fact, she gets more pleasure and use out of her binocs. Can you advise? LynnMike here: The bottom line is the short focal length of the ETX-70AT. Yes, it makes a fine beginner's telescope IF high magnification is not desired. GOTOs and wide field views are nice though. See the User Observations page for reports on the ETX-70AT as well as my experiences (linked from the top of the ETX-60, ETX-70 feedback page.
