Subject: ETX 60AT autostart Sent: Wednesday, July 25, 2007 16:10:33 From: Robert Allman (firstname.lastname@example.org) Hi Mike, lots of great information, thanks! I've had my scope for a couple of years, haven't used it in a few months. I used to do some kind of line up thing where you point the telescope totally horizontally at north and push something on the autostar and it would figure out where it was by itself. I can't find the piece of paper with that information it was a loose sheet, wasn't in the manual. Any help would be appreciated. Thanks a lot. Linda StephensMike here: You can download the manual at Meade's site. Link to the manuals is on the FAQ page on my ETX Site. You could also read through the alignment tips on the Helpful Information: AutoStar Info page; for the ETX-60 you can skip any steps that mention a "hard stop" as the ETX-60 (and -70 and -80) doesn't have hard stops.
Subject: problme de coulours sur etx 70 et 80 Sent: Tuesday, July 24, 2007 14:30:28 From: marc (email@example.com) je possede 2 etx (70 et 80) mes photos ont beaucoup trop de couleurs hallo bleus, vert, rouge. que faire Mike pour reduire les couleurs ? quel occulaire pour rduire les couleurs ? merci Votre site est superMike here: This is normal with low-end refractors. There are filters that can reduce the chromatic aberration. One such filter is the Orion "V-Block Anti-Fringing Filter", available from OPT (and elsewhere).
Subject: Advice on new ETX 80AT - needs mirror repair Sent: Monday, July 23, 2007 10:11:29 From: Deepika Bhardwaj (firstname.lastname@example.org) I found your site while looking for resources on my new ETX 80 telescope. Being a newbie, I'm completely unsure about where to find help repairing this scope. After I bought it at the Discovery Store yesterday (no returns), I saw a slip taped to the box that mentioned the "inside mirror is broken, needs to be replaced", "45 degree prism needs to be glued/replaced". I haven't even opened the box yet. This is my first telescope, and I'm not sure how to proceed. Can I fix this myself? I'm pretty handy, but wonder if this needs to be handled by an expert. And I'm not sure where I can get the replacements for the mirror and prism? Your advice will be greatly appreciated. Many thanks! DeeMike here: I'm surprised that the Discovery Store is selling known damaged goods. I would suggest contacting them first. Lacking that, your best bet would be to contact Meade but their repair will cost you $75 (minimum). Replacing the flip mirror is not a trivial operation and you would need the correct one.
Thank you for your advice - I'm trying to contact Meade Customer Support, with no luck! After holding for 15 minutes, the line just went dead. I'm trying again. Dee
Subject: Meade ETX-80AT-TC compared to other Telescopes Sent: Friday, July 20, 2007 05:49:06 From: Brian Mazejka (email@example.com) I'm a very novice astronomer and I'd like to purchase a beginners/intermediate telescope for children and myself. I want to buy something that a beginner can use but be a little bit more advanced than a beginners telescope so that I can also grow into it as well. I've heard some good things about the Meade ETX-80AT-TC telescope, but not knowing anything about telescopes I wanted to ask the opinion of someone who's a lot more experienced. Any advice would be greatly appreciated. Thanks, Brian Salem, NHMike here: The ETX-80 makes a fine beginner telescope as long as it meets your expectations of what you will be able to see. It is a low-end refractor and so you won't see a lot of details on planets and deep sky objects. I suggest you read my ETX-70 comments on the Helpful Information: Buyer/New User Tips page as well as the ETX-60, ETX-70, and ETX-80 comments on the Helpful Information: User Observations page. Remember, the best telescope is the one that gets used and doesn't end up in the closet because you were disappointed.
Subject: ETX-60 Upgrade? Sent: Tuesday, July 17, 2007 20:45:20 From: Wendy (firstname.lastname@example.org) Hi, I just came across you site and thought maybe you can help me with my Meade etx-60. I use it very casually but when I do I find that I can't get a good image of anything but the moon. Every time I try to see a planet all I get is a white dot or a purple glare. How can I upgrade without spending too much money? I'd like to see some detail. I'd love to take a good look at Saturn. Thanks, WendyMike here: The ETX-60 (and -70 and -80) are short focal length refractors. The short focal length means that you will not be able to get much magnification out of them. So seeing details on the planets is pretty difficult and will probably not meet your expectations. That said, you can use a 2X or 3X Barlow Lens to double or triple the magnification of your eyepiece(s). If you only have a 25mm eyepiece, then adding a Barlow Lens can help. If you have additional eyepieces, using a Barlow Lens can help but only up to a point, and then the image begins to get too fuzzy and dim. For the ETX-60, as you get closer to the "theoretical maximum magnification" of 120x the view may become disappointing.
Subject: ETX 70 Telescope Sent: Friday, July 13, 2007 02:47:50 From: DC60ASTR@aol.com (DC60ASTR@aol.com) Dear Sir. Having had the above telescope for several years I unfortunately had difficulty in carefully tightening the tube with the handwheel on the fork ,as a result it broke off,.In my opinion it is not worth having it repaired.In your opinion is their a diagram showing how this works as I feel it may be possible to repair this myself without any damage being caused but I am not sure how the tightening mechanism operates? Many thanks. Derek C. DC60 ASTR @ AOL.COMMike here: It won't be easy. But if you want to try it, check out the articles "Meade ETX-70AT Repair Guide". "DEC Lock Mod", "ETX-90EC DEC fix", and "ETX DEC knob fix" on the Helpful Information: Telescope Tech Tips page. The fixes for the non-ETX-70 models should be similar to what you could try with the ETX-70.
Subject: question on ETX80 45'erecting prism Sent: Wednesday, July 11, 2007 13:34:05 From: Kellie Fitzgerald (email@example.com) I hope you don't mind my email, I was searching on the new telescope I got and found your email and site. I received my telescope yesterday direct from meade and, maybe I'm doing something wrong, but it appears the erecting prism I received does not connect properly. It will not tighten enough to stay on the telescope by itself, much less with an eyepiece attached. Calls to Meade have been unsuccessful - I've been on hold a cumulative 2 hours without ever getting anyone to pick up the "consumer solutions" phone. I did get an operator to pick up and say she would "transfer me directly" but I was on hold for another 23 minutes afterwards with no one ever picking up. So, my question is "is there something wrong with this prism or am I doing something wrong?" I was able to use the telescope last night using the other eyepiece, but I would really like to utilize both. If there's something I'm not doing right, I'd love to know what it is. Any suggestions? Thanks for whatever ideas you can provide Kellie FitzgeraldMike here: As you will have noted from the Site Guide and Email Etiquette pages (required reading for first time visitors!), email is the way to contact me. I don't have an ETX-80 so can't respond directly but I'm sure that someone will respond to your inquiry.
Subject: Meade #827 8x25mm Right Angle Viewfinder Sent: Monday, July 9, 2007 16:08:28 From: Steven S. Greene (firstname.lastname@example.org) "I ordered and received a Meade #827 8x25mm Right-Angle Viewfinder for my ETX-60AT (Reference #243958). Mounting it was easily accomplished. However, when trying to align it, the instructions detail and diagram, 4 alignment screws, two on the top and two on the lateral side. Yet the viewfinder I received, has only two alignment screws, 1 at each location. When attempting to align the viewfinder late this afternoon, the two screws did not provide enough "play" to allow me to center the same object in the viewfinder that I had in the main scope." This was the email I shot off to Opticsplantet.com just a short time ago. I ordered the viewfinder to replace the 1x Daisy Red Dot that the initial owner of the scope had attached and included when I purchased it on eBay®. But I'm faced with the problem above and wonder if you've run into recently and if you have any ideas how to get around it. Thanks, Steve Greene Coral Springs FLMike here: I don't recall any similar reports. Perhaps someone with this combination will provide some feedback.
Subject: Piggyback mount for ETX-80 Sent: Wednesday, July 4, 2007 09:21:32 From: Mark (MWLibby@Charter.net) I am wondering if anyone knows of a piggyback mount that will work with the ETX-80. I have found this mount http://www.scopetronix.com/piggyback.htm which is specified for the 60/70, but when I inquired to the scopetronix "contact us" link whether it would work with the 80, they just said thay don't have a mount for the 80 avaialble. My question is wheter it is the same mount would work? The circumference of the part of the tube where the mount is placed on the ETX-80 is 10.75" (273mm). Is that part of the tube on the 60/70 the same size? I would really appreciate anyone with a 60/70 measuring their tube and replying back. Thanks, Mark Libby St. Louis, MOMike here: At this point, I don't recommend purchasing from Scopetronix. As reported here many times over the past several months, Scopetronix has been going through some hard times and service has deteriorated to the point where it is not up to their former high standards. As to a piggyback adapter, you could make one; see the Helpful Information: Astrophotography page for some ideas.
Subject: Advantage autostar 495 or 497 instead fo 494 Sent: Monday, July 2, 2007 23:53:34 From: Roger Agopian (email@example.com) Could you help me in choosing a 497 or 495 autostar in replacement of my 494 working with ETX70-AT telescope. My interest is only guided with remote control computered actions. Thanks, RogerMike here: See my response to a similar question on the current ETX-60, ETX-70, ETX-80 Feedback page. It is the top one. (Page moved to the Feedback Archives on this Site update.)
Mike, I am ok with this page but i find no comparison between 495 and 497! Could you help me, RogerMike here: The #495 is almost the same as a #497. In fact, if you can find one (they haven't been made since around 1999) they can be user upgraded via Meade's AutoStar update software to a #497. You would just need a #505 serial cable (which you can easily make; see the Helpful Information: AutoStar Info page). You will also need a RS-232 serial port on your computer; if you have only USB see the article "AutoStar and USB" on the AutoStar Info page as not all adapters work reliably with the AutoStar. If you use a Mac, you can use the AutoStarX application to update the AutoStar with the ROM file from Meade's site. If you use Windows you can update using the Meade app available on the web site. Links to all is on the AutoStar Info page.
Very good, That is why i was unable to see differences between them and why the Meade Web presents only the #497. A #495 upgraded with the last firmware version is same as #497. Thank you, Roger
