Subject: ETX-70 and Barlows Sent: Thursday, November 18, 2004 11:57:14 From: g0lws (firstname.lastname@example.org) Meade do two short focus 2 * Barlows for the ETX range, the #124 and the #126. They say the #16 can be used on any ETX. but the #124 is specifically aimed at the ETX-70. Can you tell me what the difference is, apart from price, please? 73s Andrew P.S. Just realised you have sort of answered it in your feedback. It looks like the #126 is OK for the ETX-70.Mike here: Yes, it is OK but it is slightly overkill for the ETX-70. However if you plan to use it with another telescope someday, having the higher quality #126 (vs the #124) is certainly OK.
Subject: Shipping weight and size for ETX-70AT Sent: Friday, November 12, 2004 10:09:15 From: Ola Blideskog (email@example.com) How much does a ETX-70AT with tripod weighs when shipped and how big is the package? I have tried to find out this from other sites but no success so far. Thanks in advance, OlaMike here: I checked the Shutan Camera and Video site and it shows 9 lbs for the shipping weight. Scopetronix shows 11.9 lbs.
Subject: Meade ETX-60 not working properly Sent: Friday, November 12, 2004 09:59:43 From: Thomas Dorsey (firstname.lastname@example.org) I have a Meade ETX-60 that I bought a few years ago, all worked fine when I first got it, but after moving a few times, not my azimuth will not work, ascension and declination works fine, but the telescope will not turn left or right, I contacted Meade and they told mw to open the telescope and make sure the belts were tight, as the telescope is entirely belt-drive, but all I can open is a small 2" x2" door on the bottom of the base, they even sent me a slam Allen wrench to loosen the locking lever, this does nothing. Can anyone tell me how to check the belts? Any assistance would be greatly appreciated. T. Dorsey
Subject: Should I purchase an ETX secondhand? Sent: Tuesday, November 9, 2004 12:30:55 From: Kathy Halliday (VanDuzer) (email@example.com) Hello -- Interesting site, despite my being a complete novice at telescopes! I am wondering whether I should purchase a secondhand ETX 60-AT Astroscope for $200. Do you need software with this telescope? (Vendor doesn't mention it in the ad.) I don't see this model on your webpage -- is the 60-AT terribly out of date or of risky age? Is $200 a reasonable amount to spend on a used telescope? What would likely have been the original price of this model? I've never used a telescope, but would love to learn more about the heavens. Many thanks in advance for any advice you care to offer. KathyMike here: The ETX-60AT has been discontinued although it is still available from various outlets. There are comments about the ETX-60 on the "ETX-60, ETX-70" Feedback page. You will also find some reports on the Helpful Information: User Observations page. You can also search the site for "ETX-70"; you will get lots of hit. So, there is lots of info on the Site. HOWEVER, consider that you can get an ETX-70AT (the currently shipping model) for not much more money. And no, you do NOT need software to use the telescope.
Many thanks for your reply. Perhaps I will wait until we come across an ETX-70 model before we embark on night sky gazing in earnest. I very much appreciate your advice. Regards, Kathy
Subject: 124 2x Barlow vs 127 2x Barlow Sent: Monday, November 8, 2004 03:26:03 From: Jim Morales (firstname.lastname@example.org) I own an ETX-70AT and I would like to buy a Barlow lens. Is there any difference beteween the 124 2x Barlow versus the 127 2x Barlow? Also, what is your take on the 128 3x Barlow? Great site, very informative and useful!!!! Thanks, Jim Morales Wellington, FLMike here: The #124 is a low-end Barlow Lens suitable for the ETX-70. The #126 is a higher quality one. I haven't tried the 3X Barlow Lens but reports are that it works fine on the ETX-70.
Subject: RE: Fuzzy image in a 70AT Sent: Sunday, November 7, 2004 04:54:03 From: Tom & Barbara Andrews (email@example.com) Took the 70 to our local Meade technicians. Came the diagnosis that, at some time in the past, the objective had been removed and replaced back-to-front.
Subject: Autostar model # and/or which PC cable for ETX-60? Sent: Saturday, November 6, 2004 11:36:42 From: Gareth S Bestor (firstname.lastname@example.org) I recently picked up an ETX-60 scope from Goodwill [aside - it never ceases to amaze me what people give away! :-)]. I used it to observe the recent eclipse and seems to work fine, but regrettably it didnt not come with the Autostar controller. I've done a lot of digging on the net, and your site in particular, but I'm still not clear on which Autostar controller I need to get for this model. Again, its the ETX-60, not ETX-60AT - which controller will/not work on my model? The mount has both the HBX and AUX ports. I'd also like to make/get a cable to control it from my PC serial port. I've read of some folks frying their port by building the wrong cable, and since I dont have or know which controller matches my model (505? 506? 494? 497?) I dont know which cable I should/not build. If you or anybody can tell me what controllers and/or cable I can/should use for this ETX model I would be very much appreciated. Thnx in advance. And thanks for the great site - I'm reading up on eyepieces before going out and buying a few. - Gareth Beaverton, ORMike here: The Autostar #494 or #497 will work with the ETX-70EC model. Since you want to control it from a computer and make your own cable, you should get a #497. The cable you can make is a #505. Info on the Helpful Information: Autostar Info page.
OK. So I take it there is no way to control the ETX *directly* from the computer? ie you still need an Autostar in the middle due to the proprietary interface on the base? I recall seeing some sorta "special cable from Meade" that has active electronics in it - would that allow a direct connection? So is this the difference with ETX-nnAT base models - they instead have a standard RS232 serial interface/protocol on the base? Thanks very much for clarifying. I'll see if I can pickup an Autostar somewhere (I expect it'll cost an order of magnitude more than I paid for he scope in the first place! lol) Probably waiting for one ot show up a Goodwill too is a tad optimistic.... :-) cheers, - GMike here: The Autostar is necessary for computer control. The #506 cable for the #494 adds some electronics for computer control. The #497 just needs a dumb cable. None of the ETX models have the control in the base. If you can find a #495 Autostar, it can be upgraded to a #497 via the software from Meade's site.
thanks a bunch!
Subject: Meade etx 70 Sent: Thursday, November 4, 2004 18:13:49 From: TMJD11@aol.com (TMJD11@aol.com) Hello, My name is Tim and I'm writeing you because I have no where else to turn. I recently bought a Meade etx 70 used with a celestron 9mm lens. My question is , the instructions I downloaded for my telescope from Meade says to install 3 pin light batteries but I have a hook up for a 9 volt? When I hooked up the 9 volt I have no sign of life on the Autostar control? Can you give me any help.... as you can tell I'm new to the telescope adventure. Thanks for your time TimMike here: The ETX-70 actually uses 6, not 3, AA batteries. You should have received a battery pack where the batteries are inserted. This pack connects to the ETX via that connector where you are attempting to use a 9V battery.
Thanks guy! You have a great site and have answered many questions. Tim
