Subject: ETX-125/EC Sent: Friday, April 30, 1999 11:19:58 From: email@example.com (Mike & Debra) Meade is also playing dumb with us at the current moment...they are telling us that a totally new "line" will be available in late May/early June, but no other information. In fact, the #505 cables still can't be had yet, and our "promised" hard cases were supposed to be in over two weeks ago. I just can't wait to see it and play with it...I owned the old ETX and upgraded to the LXD-500 when it had its serious price drop, but if a bigger scope can be had WITH all the motorization, I want to go that way. I love the LXD because and 8" is so much more impressive than a 90mm, but I do get lazy sometimes and would like a "GO TO" function for my scope. Estimates for the ETX tripod were last August, but we didn't receive them in any quantity until the end of September, as was the case with the ETX-90/EC...we were supposed to get those in early February, but they came near the end of the month.

Subject: 125 & Natural Wonders Sent: Friday, April 30, 1999 10:10:25 From: firstname.lastname@example.org (Gary) I just spoke with the manager of my local Natural Wonders - last night i replaced my 90 EC for the third time - first time Goto tracking problems (would lose alignment after one or two slews), second scope never got to align - wouldn't focus properly, then a funny clanking noise in the focusing knob - not a good thing. Received scope number 3 yesterday, but didn't open it yet. I spoke with the manager today (wasn't there last night) and asked about the upgrade path to the 125, if any. She told me she didn't know about the scope yet, and that i probably knew more about it than her (of course, I read the Mighty ETX site, as all good astronomers should!). She told me Natural Wonders does not find out about new shipments until about 1 week before, but if they carry it (and she guessed they would, as it is an ETX), that as long as i had the ORIGINAL RECEIPT and BOX, they would take it back and I'd pay the price difference (about 3 bills) - BUT if they don't carry the 125, they wouldn't be able to take my scope back. It's a risk I'm willing to take - I just hope i won't have to go through 3 125s! Hope this was informative... Happy slewing, Gary
Subject: ETX-125/EC Focal Length Sent: Thursday, April 29, 1999 9:05:41 From: JDeriso@Alphaind.com (Deriso, John) I confirmed the 1900mm focal length with Meade this morning, because I'm wondering about updating from the -90/EC which has 1250mm. I think this implies, for a given eyepiece, 52% increase in magnification and 66% reduction in actual field of view by simple ratio of the focal lengths. The clear aperture area increases by 93%. Does this mean (compared to the -90/EC and the same eyepiece) that an object's apparent brightness would increase 93% due to the larger aperture, but be reduced 66% due to magnification, for a net gain of 27%? And at 60x per inch, 300x might be practical, so what about that note from Phil Acker (April 22) where they suggest 500x limit? John DerisoMike here: There was a recent, long, discussion about this on the ETX Mailing List. Quoting from Rod's response:

Subject: RE: ETX/125EC Ball Bearings Sent: Monday, April 26, 1999 18:33:27 From: DonMcClelland@webtv.net (Donald McClelland) Judging from the E-Mail response I've been getting, I feel I should be a little clearer about the ball bearings in the RA. I noticed the similarity between the LX200 (Nylon for the Dec, Ball bearings for the RA) and the ETX/125EC from the specs in the Meade catalog. This seems to me to be an obvious upgrade for those of you that did not understand. I guess I kind of got excited about sharing the news. I'm not an expert but this may reduce tracking and/or pointing errors that have been seen in the ETX/90EC in some cases. Hope this clears it up. Thanks for your response everyone. DON

Subject: ETX 125/EC TeleWrap/Dew Cap Sent: Friday, April 23, 1999 21:32:44 From: firstname.lastname@example.org (Barry Craig) I just wanted you to know that we will be manufacturing a TeleWrap/Dew Cap for the New Meade ETX 125/EC. The price and availablity to be determined. Sincerely, Barry A. Craig (Clear Night Products) 248-547-2315 http://home.earthlink.net/~barrycnp
Subject: More info Sent: Friday, April 23, 1999 18:18:28 From: email@example.com For your information, the street price for the 125/EC is $900 and includes the 8x25 R/A finder. There will be a new, larger hard case and a new electric focuser that differs from the 90/EC focuser. There is also a new table tripod that includes a leg weight. The deluxe #883 tripod fits both the 90/EC and 125/EC. While the 125 gathers twice the light of the 90mm... it is also twice the weight: 19lbs. The original ETX Astro has been renamed ETX-90/RA and is now priced new at $500. There will also be a 125/EC spotter available. Sincerely, Shutan Camera & Video www.shutan.com
Subject: ETX-125EC Info Sent: Friday, April 23, 1999 16:34:05 From: firstname.lastname@example.org (Steven Jindra) I went to Land, Sea and Sky in Houston, Texas today. They just received the new Meade Catalog with the ETX-125EC information. Some of the specs are: 127mm(5")Aperature, 1900mm f/15 focal length, 18.8 pounds, and it includes the 90 degree 8 x 25 finder scope. Their retail price will be around $925.00. They are due to be shipped from Meade on May 1. (Anyone want to buy an almost new ETX-90EC?) Thanks for your site. Steven Jindra.
Subject: Yet more 125 Info Sent: Friday, April 23, 1999 8:51:15 From: email@example.com (Gary) Here's something I found on an ETX forum... - incidentally, Astronomics has the 125 listed for $895, but they don't really give much info - if you click on it, the link goes to the 90...the 125 comes with the right angle finder, so in a sense it might only be $250 more than the 90 (i was planning to buy the right angle finder, maybe this is why they weren't available for a while?) I wonder how many bugs will be in these units - I expect the optics to be terrific, but perhaps there are mechanical difficulties, like missing stops inside, etc...(or should that be etx...?) I am wondering if I would see a benefit in my light polluted skies - the new scope is twice the weight (if the stats are accurate), and will probably not fit in my doskocil case (can you say expensive custom case needed?) : : :If you want to see pictures of the new ETX-125EC, check out the anyone know the specs - f ratio, size, weight, etc.? Specs are: > >Dimensions------19" x 8.9" x 10.8" > > Weight------------- net weight---- 18.8lbs. Shipping weight ---- > >23.7lbs. > > > >Also it has a focal length of 1900mm f/15 Comes with the 8x25 right angle finder, fits the existing ETX tripod... And the Autostar DOES support it. Why wouldn't it? The first inkling that there would be an ETX125 was from people who explored all the Autostar menus and FOUND the ETX125 already listed there. This came from the ETX forum cited from the ETX link at the bottom of Scopetronix's tips page, i think it is JBF's or something to that effect....happy slewing!
Subject: More ETX-125EC Info Sent: Thursday, April 22, 1999 21:29:38 From: firstname.lastname@example.org (Phil Acker) I have received a few Emails asking about pricing on the new ETX-125EC, Well Ill tell you right now, Im no expert on the new scope but Ill tell you what I know. My friend with the ETX-90EC went to Meade today to get a catalog and was asking them about the ETX-125EC. It is not a released product at this time, and they wouldn't give an estimated price, but Ive heard from several scope shops: Under $1000.00 & Around $900.00. So Its hard to tell at this point. Also, Meade has been hard at work lately. There seems to be 2 or 3 different Autostar computers controllers now #497 (ETX controller with many new improvements, 14,487 objects now) & #492, 493 (1500 objects) for their new line of Digital Electronic Series Scopes (60, 70, 80, 90mm refractors & 114, 127mm reflectors). They also 2 new PC scope controlling software besides EPOCH 2000. SkyChart Astro (for the #497/ ETX) & StarNavigator (for the new #492, 493/ Digital Electronic Series). Back to the ETX-125EC: It comes standard with the new 8 X 25 right-angle view finder and have replaced the nylon R.A. bearings with ball bearings. Ive attached some specs for it: Optical Design Maksutov-Cassegrain Primary Mirror Diameter 138mm (5.43") Clear Aperture 127mm (5.0") Focal Length, Focal Ratio 1900mm W15 Near Focus (approx.) 15 ft.

Subject: ETX 125 price Sent: Thursday, April 22, 1999 20:16:35 From: email@example.com The Astronomics web site has the ETX 125 listed as available for $895. I don't know if that is an estimate or actual. If it is actual I think Meade will put Celestron and other competitors in a deep hole. I would buy the first 125 I could get and then buy serious Meade eye pieces to support a company that would make such high quality optical system available at a price many can reach.
Subject: ETX 125 now on sale Sent: Thursday, April 22, 1999 16:41:45 From: firstname.lastname@example.org (Don Middendorf) You have a great site! I ordered an ETX 125 today from Astronomics $895 without the autostar. Ship date is "late May, but more likely late June". As another post on your site said, Barbara at Astronomics is very nice and helpful.
Subject: New ETX Sent: Thursday, April 22, 1999 13:47:20 From: Peter_Eggert@adsu.bls.com (Eggert Peter) Thanks for the update on the new ETX 125. Any idea on availability and cost? I'm just starting out and would like to look at the new 5" model before I make any purchase decisions. Thanks for the site - lots of info to help us starters out! Peter
Subject: ETX-125/EC Sent: Thursday, April 22, 1999 9:57:47 From: LooneyRoo@aol.com i just wanted to let you know that i spoke with meade a couple of days ago and they would not even confirm that the scope was coming out! it was not until i told her that i had seen pictures of them that she stopped playing dumb. she then conceded that the scope was out, but would not even hint at the price. she said that "givng out prices is only allowed if we can take orders, and since the scope isn't available for ordering, i can't price it for you." i've heard rumors on other discussion boards that it might be available at the end of the month... as for price, someone predicted that it would be just under the $1000 mark ($999.95). if that is true, why not just get the 8" lx10? unless you already own the autostar, you'll have to spend an addtitional $150 anyway. the difference then would be like $200, for the magellan I... not much for 3 more inches of aperture. i don't know... it looks like a nice scope, but if you already own the etx and are interested in a larger one, you might as well go with an 8" or 10" rather than a 5".Mike here: Rumored price now $895 (US). Rumored availability in June 1999.
Subject: ETX-125 Sent: Thursday, April 22, 1999 8:40:57 From: email@example.com (Michael A. Covington) Greetings, I don't have an ETX-125 yet (who does?) but would like to know... (1) How far south will it point in equatorial mode? The ETX-90 is limited to declination -30 if I'm not mistaken. (2) Is the drive smooth enough for photography? Clear skies, Michael A.

Subject: etx 125 Sent: Thursday, April 22, 1999 5:54:19 From: firstname.lastname@example.org (renefigueroa) just got in late last night. have been on the road the last 3days, however the new general catalog was waiting for me with pictures of the new 125 and a new version of the etx 90 with just one motor and no hand controller. meade also says it is not upgradable.
Subject: ETX-125/EC Sent: Wednesday, April 21, 1999 18:33:28 From: email@example.com (Phil Acker) Hi Mike, love your WEB site. About six months ago, I started looking at the LX200 10" as a replacement for my Meade 2045 (4" sct). I have a friend that has one, so he invited me over for a night of star gazing. I also have another friend that has an ETX 90EC that wanted to go as well. So they set up their scope and we started. The LX200 was nice, but with the larger images, they were dim and fuzzy (Orion Nebula). Then over to the ETX, WOW.... smaller but crisp and somewhat brighter. Looking at the hassle of setting up that 10" LX200, and ease of the ETX, I was sold. But I remember telling my friend, If they only made an ETX 5". Well they do now. I work 2 miles from the Meade factory in Irvine. After reading about one of your readers getting a catalog in the mail with the ETX 125 EC in it, I went to meade. The Jpgs attached are from the catalog. Enjoy Phil Acker
