Subject: EyePiece suggestions for the ETX-70 Sent: Monday, September 25, 2000 16:02:33 From: firstname.lastname@example.org (Jason Shea) What eyepieces would one recommend for the ETX-70. I have the 26mm and 9mm that come with the scope, and was thinking about getting something like a 6mm or less to see the rings of Saturn a bit better. My concern is that i will be unable to resolve the image with any detail. Can anyone recommend which eyepiece below 9mm would be the limit for getting decent sharpness? Also, anyone recommend which filters to get for viewing deep space objects? thanks Jason
Subject: EXT 70AT ?Good value? Sent: Sunday, September 24, 2000 07:39:46 From: pvak@CAM.ORG (Peter Vaktor) Has anyone had any experience with the new EXT 70 AT refractor scope with Autostar, in comparison with the EXT 90EC? Would this make a good first telescope for primarily planetary observation? Or would spending three times the price, for an EXT 90 EC, be worth the investment in the long run for the return of improved image quality? Or, at these small sizes of scopes are any differences in resolution and capability usually overshadowed by the observation conditions and it really does not matter much? In other words how good is this little refractor when compared to the 90EC's acknowledged excellent image quality. PeterMike here: Optical reports on the refractor are good but you'll get better views with the larger aperture of the ETX-90EC. See these ETX-60AT, ETX-70AT Feedback pages for more reports.
Subject: Great site Sent: Saturday, September 23, 2000 17:04:00 From: email@example.com (Bruce Harke) Glad I found your site. Looking at possibly buying an ETX-70-AT with the Autostar #495 tomorrow and wanted to research it a little bit to help convince myself. Found one at a Natural Wonders Science store for $296.95, so after checking out your site, I think I am going to jump on it. Sounds like a good deal for a good basic telescope. Thanks for your site,... the user comments convinced me. Your site is now on my favorites list. Bruce
Subject: etx 60at photo Sent: Thursday, September 21, 2000 17:17:51 From: QCarroll@aol.com Love your sight. Are any of the photos on your sight taken with the etx 60? Is there any practical way to increase magnification with the 60 for photography? What about CCD? Thanks QuintonMike here: I don't recall any ETX-60AT astrophotos as of yet. If you want to try eyepiece projection, you can use a Barlow Lens or different eyepieces. Of course, you'll need the appropriate adapters. CCD imaging should be possible, especially with something like the SAC IV imager.
Thanks for the quick response. What kind of adapters do I need for eye piece projection?Mike here: Check the Accessories - Astrophotography page.
Subject: ETX70AT tripod & accessory question? Sent: Saturday, September 16, 2000 09:54:18 From: AlAlborn@aol.com I just bought an ETX70AT and got my first look at the surface of the moon (what a rush). I notice that my ETX70 looks different from the models pictured in Meade's Sky & Telescope adds. My ETX70 has the same base as the ETX90 (or so it seams). My ports are in the base. Scopes advertised have one less port and are in the arm. I also have a controller that looks like the ETX90's (vice a simpler model pictured). Is my ETX70 an older model? (I suspect that early ETX70's used the same base as the 90. Correct?) The reason I'm asking is because I'd like to get a tripod. The book for my ETX70 lists the #883 Deluxe Field Tripod. The adds in Sky & Telescope lists an 882 Standard Field Tripod. I'm wondering if the standard field tripod (and other ETX70 accessories) will work with my ETX70. I also notice the scope advertised doesn't list an equatorial table tripod (or appear to have the holes to support one - in the picture); however, I'm using the one designed for the 90 with mine. I'm also wondering if my autostar controller is the same as the 90 (and if I can download the 90's database). Overall, I think I prefer my model. It appears that I can use all of the 90's accessories (thus giving me an upgrade path) and have a little more functionality (the extra port and what looks like the same controller as the 90). What do you think? Regards, AlMike here: There do appear to be different models of the ETX-60AT and ETX-70AT. Meade's current catalog (paper and web) shows the model with the ports in the fork arm.
Information from Shutan Camera and Video:
Sent: Saturday, September 16, 2000 18:32:33 From: firstname.lastname@example.org (Bob Shutan) We have 70's with base ports and 60 /70's with arm ports. All versions use 2-hole mounting such as that required for 883 deluxe tripod or new 882 alt-az tripod. bob.
Subject: 60/70 Sent: Friday, September 15, 2000 20:41:42 From: email@example.com (Bob Shutan) Just to let your readers know (maybe I missed a posting) but the base of the 60/70AT is just like the 90/125EC. A common adapter plate such as the one we carry from Scopetronix, or our ETX Easy Mount is all that is needed. But.... their tripod (mainly the leg locks) must be able to handle the 8-10 lb. load which many photo tripods can't. By the way, 60AT's and 70AT's are not on backorder as of this writing. -- Sincerely, Bob Shutan Shutan Camera & Video www.shutan.com
Subject: ETX-60AT Review Sent: Friday, September 15, 2000 11:59:43 From: firstname.lastname@example.org (David Langham) It seems as if I'm the only person around who has a ETX-60AT and not an ETX-70 or 90. Anyway, just wanted to provide a little information about the performance of the ETX-60 for anyone who is thinking about purchasing one. Last night (first clear night in awhile) I tried out my ETX-60 for the first time. Jupiter, Saturn and the Pleiades were very bright. Anyway, after a two star alignment, the scope performed very brilliantly. With a simple 9mm eypiece I was able to easily see the rings of Saturn and two moons of Jupiter!! The Pleiades were fascinating. I was very happy with the ETX-60. I have just ordered Plossel 4mm and 5mm along with a 2X and 3X Barlow lenses. I can't wait to see what these can do. Anyway, for those of you that think the ETX-60 is too small or only for beginners, think again. It was the best $299.00 I've spent in a long time.
Subject: 9 volt etx70at Sent: Thursday, September 14, 2000 15:39:57 From: email@example.com (Gary) I just bought an ETX70at and in the battery compartment there is a battery holder that comes out.You put 6 AA batteries in it.This holder connects to a 9 volt battery snap on connecter.Does anyone know if I can just use a 9 volt instead of 6 1&1/2 volt AA batteries.I ask the tech at Meade but he said he didn't know. gary
Subject: Re: Meade ETX-70AT Question Sent: Thursday, September 14, 2000 08:20:23 From: firstname.lastname@example.org (Szrir, George) Just a few lines to let Stefan Kowalzik or anyone else looking for an ETX-70 (or any other scope for that matter) to try giving George at Science and Hobby a call (they are located in New Paltz, NY) www.scienceandhobby.com 914-255-3744 or 800-763-3212. Before buying my ETX, I shopped around the local stores, the internet, and used "The Mighty ETX site". I ended up finding Science and Hobby on the Meade dealers page, and am very happy with them. I called George on Tuesday with a lot of questions concerning various scopes, and he was very patient and helpful. I of course ordered the 70 from him. He had it on my doorstep the very next day! (I live in NY, so UPS delivers ground packages in one day within the same zone) I've only used this scope once, but was able to see Jupiter with moons, and Saturn with rings!! (probably boring stuff for you pros, but quite literally one of the most amazing things I've ever seen!!!).... I should mention that I was using a 2X Barlow lens and the 9 mm eyepiece supplied with the ETX. George Szrir Clay Finlay Inc.

Subject: ETX-60AT Sent: Tuesday, September 12, 2000 20:53:31 From: TC26DEE@cs.com Hey Mike, great web site! I just bought an ETX-60 about 2 weeks ago. I love it! But I am finding it hard to find accessories for it. Such as stores, web sites, etc. Can you help me? The store I got it from was a wal mart supercenter. they do not carry any accessories. Also, a salesperson said that I could use accessories for the ETX-90 on mine. I really don't believe this. This isn't true is it? Thanks, Tony Merritt Easley SC firstname.lastname@example.orgMike here: If the ETX-60AT uses 1.25-inch eyepieces, then you can use most 1.25-inch eyepieces, filters, and some Barlows. I say "most" and "some" since I don't know how much focus travel there is on the ETX-60AT. Check the various dealers listed on the Astronomy Links page.
Subject: Re: Meade ETX-70AT Question Sent: Monday, September 11, 2000 14:32:26 From: email@example.com (Michael Ryan) A little less than a week ago, I finally got my new ETX-70AT. Meade has been a little slow to get these to market... To "Stefan Kowalzik" who wrote you about were to find the new 70AT's while he is in the U.S., suggest that he use the dealer finder on the Meade site. I received my from Berger Brothers Camera (on Long Island). Some of the sale people really new what they were talking about when it came to telescopes. I have had some success with the two viewing nights so far... The first night, it was cold and the telescope dewed up after about 2 hours (around 11pm). Due to the sites so far, I have had no luck with polar aligning using the Autostar. My problem is that my In-laws backyard...while dark, has tall trees on all three side of the yard, house on the fourth. There is no way for me to see Polaris, or many of the alignment stars. (Any suggestions on this problem?). However before the due set in, I was able to do some viewing of the Moon (able to see "straight wall") and some deep sky panning. Stars were just pinpoints of light...Never saw so many stars with my own eyes! Seems as if the Aligning steps for the 60/70AT's are a little different then the 90/125's... The second night 9/9/00, much darker sky out east on Long Island. Cool night, out east with friends playing poker. Thought I pack up my little 70AT for a trip incase the sky was clear. The Moon was great again around 8pm...easy to find in the night sky. Again, no change to align due to I was setting this up in a strange place, and I was there have fun playing cards. Cards finished at midnight, and again I had just a few minutes to see Jupiter and Saturn, before I had to leave. Got both of them as 3 moon of Jupiter. Very clear. Need a to buy some other eyepieces...a 2x or 3x should do the trick.. So far so good! I am very happy with my scope so far... 1) easy to transport... 2) clear optics... 3) good price... Now if I could just buy a mountain top with dark skies next to my home... -- Michael D. Ryan firstname.lastname@example.org - email (212) 699-3827 x2450 - voicemail/faxMike here: Since you have the "AT" model, don't bother with Polar aligning; use Alt/Az. That way, you don't to explicity see Polaris; just get approximately North (but as close as you can in the Alt/Az Home position). Hopefully that works with the ETX-70AT model.
Problem is that with all of the trees, alignment stars have to be almost overhead!Mike here: Oh. Well, you can use a magnetic compass and correct for your local magnetic variation.

Subject: ETX-70-AT Sent: Thursday, September 7, 2000 11:24:34 From: firstname.lastname@example.org (Stefan Kowalzik) Hi and congratulation to your very informative site... I come from Germany and I'm working in New York for two months. I tried to find a Meade ETX-70-AT but no dealer seems to have it - the 60 is available everywhere.... Maybe I have luck with my question at Meade. One other thing is not really clear to me: I own a really heavy tripod for photography and I would like to use it with the ETX. Is it possible to mount the telescope on the standard screw of the tripod or do I have to use an adapter (I this available or do I have to make one ...) ??? Best Regards from a new ETX-fan, Stefan -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-. Stefan Kowalzik email@example.com -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.Mike here: You can use a photographic tripod but you will likely need some sort of adapter plate. Several are available; check the Accessories - Tripods page for some and also check the Tech Tips page for some ideas on building your own. I don't know whether any of the commercially available ones will work with the ETX-60 and -70.
Subject: ETX 60-AT Sent: Wednesday, September 6, 2000 12:49:38 From: firstname.lastname@example.org (David Langham) Hello! I recently purchased a new Meade 60-AT telescope after returning a older black tube ETX 70-AT. Although not as powerful as the old 70-AT or the new 70-AT's, I have to say the improvements provide for a much better scope. Even though the new 60-ATs don't have the numeric Autostar or a 12-volt DC port I am much happier. The horizontal axis does not have any "limits of revolution". I can turn the axis with no fear of damaging any internal structures. Also, they have improved upon the internal gears which prevents too much backlash when slewing to objects at higher speeds. Now for my question(s). First, what is the difference between Plossel eyepieces and Super-Plossel eyepieces? Second, are the 2X or 3X Barlow lenses worth the cost or do they simply make the image appear more fuzzy or "out of control". Lastly, would you recommend investing in a viewfinder (do you have one on your ETX-90, and is it necessary?). Thanks Mike, great site!!!!Mike here: For a discussion on eyepiece types see Orion's eyepiece selection. While it doesn't discuss Meade's Super Plossls, it may help. Don't know whether Super Plossls would be overkill for the ETX-60. Finderscopes are handy for getting the telescope quickly pointed in the right direction for non-GOTO operations. If you only use the Autostar then a Finderscope on the ETX-60AT is less useful.

Subject: ETX-70/70 Questions/Answers... Sent: Thursday, August 31, 2000 07:39:15 From: email@example.com (Jordan Blessing) I just wanted to respond to a couple of questions I just read in the ETX 60/70 feedback section... To Emanuel regarding Piggyback Mounts: We have piggyback mounts for the ETX60/70 in stock though we haven't had a chance to post it on our website yet. It attaches behind the front portion of the tube and includes a special counterweight set that attaches to the eyepiece to keep things in balance. To Richard Jacobs regarding Focuser travel: Yes the ETX 60/70 has a *very* long focuser travel and your experience is normal. Since there is currently no electric focuser available for this scope you may want to take a look at our Flexi-Focus unit. It is now available for the ETX60/70 and believe me it is a big help (especially when pointed up). These are not on our website yet but are available. Thanks. -- Jordan Blessing ScopeTronix Astronomy Products www.scopetronix.com
