Subject: ETX 90 spotting scope Sent: Wednesday, May 31, 2000 14:10:05 From: Mal47@aol.com I just bought a T-adapter and Nikon T-ring for my ETX 90 spotting scope (not the telescope version). Do you have any information on the feasibility of taking daylight terestrial pictures with the scope? I know you emphasize astronomical uses for the ETX, but I thought you might know something about daytime pictures, or maybe you could steer me in the right direction to learn more about it. The folks at Meade haven't really been able to tell me much about it. As usual, I am grateful for your great site, and for any information you might have. Take care, MalcolmMike here: The ETX makes an excellent terrestrial scope. Search the site for "terrestrial" and "birding" for more info. You'll find some photographic info there. Basically you'll have a 1250mm telephoto lens.

Subject: Cheap CCD non cooled camera Sent: Tuesday, May 30, 2000 21:59:18 From: firstname.lastname@example.org (William Behrens) Here is an eyepiece projection camera thats color and very nice for the price.....FYI. I'm thinking of buying a ETX125 but just haven't made the jump yet. Have you heard of these guys before? Seems to good to be true. Link members.xoom.com/sonfest/ WilliamMike here: Yep, seems to be a good product. I've been told I would receive one to evaluate but it hasn't come yet. There is an example at the bottom of the Guest Astrophotography - Planets page on my site.
Subject: ETX pricing Sent: Tuesday, May 30, 2000 10:26:04 From: L00RLR@FDS.com (Bob Ryan) I just read your email to Camera World. I think I found a place that is charging even more. My wife and I took a trip to Seattle and I was perusing the "SkyMall" magazine that was on the plane. I couldn't believe what I saw. When I got home I checked the web site to be sure.

Subject: Color filters and Solar observation Sent: Monday, May 29, 2000 15:34:50 From: email@example.com Today as an experiment I decided to do some solar observation using a Thousand Oaks type 2+ solar filter and different color filters. Most of the filters I used didn't make any improvements, however I found that by using a #15 yellow or a #23A red filter improved the contrast of brighter spots on the Sun, (I assume these brighter areas are flares?) Anyway I found the #15 yellow filter gave the most contrast, so I'll probably use this combination from now on. As far as solar observing today goes, there are some nice large sunspots toward the center of the solar disk with some smaller ones near the edges with the brighter areas also near the edges. Clear Skies!! Carl Stanley Mountain Home, IdahoMike here: Thanks for the report. Those bright spots are called "faculae".

Subject: General Interest - Space Physics etc... Sent: Monday, May 22, 2000 17:49:54 From: email@example.com (Patten, Scott D) G'day Mike, I hope you have been well. Found this site and has an amazing amount of info, pictures, movies and explainations for would be star travellers.. http://www.fourmilab.ch/cship/cship.html Regards Scott Patten * mailto:firstname.lastname@example.orgAdded later:
By the way , I love the new photo and what you have done with the site. I was out at my sister's block a couple of weeks back. Heavily treed but saw enough of the sky. Spent most of the night in black, clear skies before the full moon took hold. Black skies does have its drawbacks though, you really have to know your star positions to get around. Got the biggest fright of my life when meteorite burnt up in the atmosphere. I saw it make its way through about 45 degrees minimum of the sky. It was a great start. Spent the pre full moon part of the night checking out Orion and M42/43. I am hunting around to find a good map of Orion as I had skies dark enough to crank the magnification up to about x260 which made the 2000 lb telescope pier (Car roof) great for the smalles of vibrations. Found 4 little stars that I thought might be the Trapezium so I will check the books and find out exactly what was taking my time. Once the moon was up slapped on the filter and check out the craters etc. No Matter what they say anytime is good to look at the moon. Winter has set upon us with avengence. 16C and Sunny....Still no rain, so droughts for Melbourne but that can be a benefit during the night.
Subject: A small but usefull tip for better photographs Sent: Monday, May 22, 2000 07:19:22 From: email@example.com (Karytianos Nicolaos) I am a newbie in the world of astronomy and I plan to buy a Meade ETX90 EC. I looked for info about it in magazines but mostly in newsgroups (since no sites about it exist) such as sci.astro.amateur and they noted me your fab site. It was more than I expected with complete and comprehensive details that no astro magazine or telescope dealer can provide. Thank you for your invaluable help. I have seen in your galleries those photographs accompanied with an note about blur due to mirror/shutter motion. So here is a small tip for long exposures using reflex cameras: If the exposure is of a considerably easy to count period of 1 or 2 seconds you can eliminate the efects of camera vibrations buy using the B (or T in Nikon) setting. First aim at your subject. Then hold a dark coloured paper in front of the lens to block all incomming light. Now let's say that the exposure is 5 seconds. Set the camera at B, fire-hold the shutter, let the system relax for a few seconds, then remove the paper, count 5 seconds and then block incoming light and close the shutter. I used this technique for night scenes with my Nikon and it produces really sharp images. Best regards, Karytianos NikosMike here: This is commonly known as the "hat trick" method.
Subject: Custom 'ETX' site Sent: Sunday, May 21, 2000 10:27:04 From: firstname.lastname@example.org (guillaume dubos) Hi ! I've decide to transform my ETX into a goto-scope for CCD. Basicaly I place it on a GP mount, with skysensor2000 and the CCD camera Audine (KAF-400 based, cheap, so great). I've place on my site, etxgp.free.fr/indexeng.htm , the whole transformation, techniques, technical description. It can be a good solution to people which want to evolve, keeping the quality of the ETX... Tell me what you think ! Have a nice day (and night!) Guillaume

Subject: ETX 90 Sent: Tuesday, May 16, 2000 13:59:39 From: firstname.lastname@example.org (Svend Karlskov) I' ll now try to be more explicit. I shoult like to make photos with my telescope. I have the camera and the adapter. Whith film is the weight all together 783 g. What I need now is a balance weight. I think about a short tupe, f.eks aluminum, at the objektive end of the telescope. My questin is, can you tell me aboute the thread lead/pitch. Best regards SvendMike here: Thanks. I'm still not certainly exactly which threads you are talking about. At the objective end there are two sets: one that the cover screws into and the other is what the corrector lens itself screws into. You really don't want to remove the corrector lens so that leaves the cover threads. I don't have any way to measure them but you can take your cover to a local machine shop and they can measure them and thread the tube you want to add. If I've got it wrong, let me know.
Subject: ETX photography Sent: Sunday, May 14, 2000 22:44:59 From: email@example.com (Ulrich Beinert) I surfed by your site again today, after looking at other sites for about a year. I still think yours is the most complete site about the ETX. I enjoy reading the reviews of all accessory products for the scope, which are of course not geared towards one dealer or the other, but rather towards what is best for the *user*! Thank you for this. However, I think some reader reviews should be edited for brevity, clarity, spelling and grammar, as should the captions on some of the photos. Regarding photos, I have taken some of my own ETX shots, the best of which I have published on my web site (http://www.analemma.de). All of the piggyback and all of the solar lunar and planetary (with exception of two images) photos were shot using the ETX. This is also noted in the "Exposure data" part of each page. Feel free to take any of the photos and use them in the reader gallery; just add my name and the exposure data. I think, since the pictures are already on the web, it is easier for you to just take them onto your hard disk instead of me sending each one to you. The best photos you might want to use on your site are the following: www.analemma.de/mooncomp.html (Composite of 3 moon photos taken with EP projection) www.analemma.de/zetori.html (Nebulosity around zeta Orionis www.analemma.de/qtmoonpr.html (Quarter moon, eyepiece projection) www.analemma.de/sag.html (Summer Milky Way) www.analemma.de/saturn.html (Saturn, EP projection, great!) www.analemma.de/jupiter.html (Jupiter, EP projection) www.analemma.de/jupmn.html (Jupiter with galilean satellites) Take a look at the other images as well; they may strike your fancy as well. If you do use any of the picture (and I hope you will!), please send me a note saying so (so that I can take a look at them on your site) and *please - credit me with a LINK TO MY SITE* (www.analemma.de ). That way, people who want to see more of my work can surf directly to my site. Once again, thanks for such a great and complete ETX site, keep up the good work!

Subject: AC Adapter Sent: Saturday, May 13, 2000 20:50:56 From: email@example.com (Steve) I have been searching your site and see all kinds of modifications, accessories, etc. One thing I haven't found is the AC Adpapter connection. Is the pin positive? I bought an adapter at Radio Shack that allows me to select polarity but I don't know what the ETX is. Thanks, steveMike here: There are several power supply discussions on the Tech Tips page. In several places it notes the center is positive.
Thanks for the quick response Mike. Yeah, I guess I was looking for a simple adapter article. All the articles I saw were explaining how to rewire this or that. My eyes are a bit tired tonite so I must have overlooked those two words: center pin.
Subject: ETX 90 Sent: Saturday, May 13, 2000 11:56:58 From: firstname.lastname@example.org (Svend Karlskov) I am about to create a tube for my ETX 90.

Thread to what?
Subject: ETX as an RFT Sent: Thursday, May 11, 2000 17:28:53 From: DonMcClelland@webtv.net (Donald McClelland) I was wondering if you new what the lowest possible power the ETX-90 could use before the secondary obstruction became apparent. Probably an interesting question for the 125 as well. I read on your Rini eyepiece reviews that the ETX could be used as a Rich Field Telescope (salivating)! They were talking about the 45mm Rini with the focal reducer? I think that would be pushing it. What do you think? She said about the 45mm "so much for the ETX being unsuitable as an RFT", implying that we have more of a scope than I thought. Clear Skies, DonMike here: I used the Scopetronix 40mm eyepiece with the Shutan Wide Field Adapter on my ETX-90RA. Worked pretty good. As to what the limit would be, I don't know.
Subject: response to note on ETX photography Sent: Wednesday, May 10, 2000 19:21:47 From: email@example.com (Frank Goldner) There appears to be something illogical to Todd Blumer's May 9 note, posted in your ETX User's Feedback section. The note refers to T-adapters for both the ETX and his Nikon camera, and notes an unsatisfactory object viewed in the camera. First, only the ETX has a T-adaper; a camera is usally attached to a T-ring (or "T-mount" in the ETX manual) after the camera lens is removed. So, assuming Todd really has a T-ring or T-mount mount for his Nikon camera, and it screws onto the ETX T-adapter, he is engaged in a prime focus situation -- unless he stuffs a 26mm ploessel eyepiece into the T-adapter extension section, as some of us have done, to create a nice eyepiece projection situation. If this is the case, his only real problem may be one of focusing; usually the camera film plane is not in focus when the ETX eyepiece is focused -- i.e. they are not par-focal; they can be several focus knob turns apart. Now, that the Moon is high in the evening sky, would be a good time for Todd to recheck his setup. Lastly, using the eye to look into the prime-focus port to check if the camera setup is o.k. is no good as the eye has a lens, and prime focus doesn't - other than the main ETX optics. Good luck Todd. As mike implied, you should be able to do ETX photography whatever your setup; just look at the great photos in other sections of his site. Frank Goldner, Bethesda, MD firstname.lastname@example.orgAnd more:
Frank, Thanks for the additional information. The problem, I believe (with my little understanding of the subject at this point), is that my Nikon digicam cannot have its lens removed (as far as I can tell). I do have a T-ring for the camera (from http://www.ckcpower.com), but it threads into what-would-otherwise-be the lens filter threads. So, I believe I need an eyepiece to "stuff into the T-adapter extension section" as you describe. Where can I get such a beast? My "normal" eye pieces do not fit. Thanks!
Subject: New Site for Discussions Sent: Wednesday, May 10, 2000 17:02:37 From: email@example.com (Robert Schlackman) Hi, I just started a new web site called the ETX Communications Project. The web site has forum discussion capabilities and is hosted on a dedicated server. I've created this site with one thing in mind, creating a high performance forum for ETX users to chat and participate in online discussions. Please help get the discussions started. I've also added a Links page that will allow anyone to add their links on-the-fly. etx.mine.nu Thanks, Rob
Subject: lens coatings Sent: Wednesday, May 10, 2000 10:59:15 From: Astro1807@aol.com on the lens of my etx, I have noticed there are a bunch of bright spots. I think the manual mentions these in the maintenance section, when it talks about the "flashlight test". I have also noticed these on Meade super plossol eyepieces. Will these degrade the images at all? Is there a way to clean and get rid of these? I'll send a picture of these so you can see what I mean.
Mike here: These appear to be "dew spots", which can result from not letting any dew evaporate before covering a lens with a cover. If that's what they are, check the "Cleaning Optics" on the Buyer/New User Tips page.
after looking at that i cleaned off a couple of the bigger spots with lens paper and Orion multi-coated lens cleaning formula.
Subject: ETX 90 with the Sony cybershot 505 Sent: Wednesday, May 10, 2000 04:34:53 From: firstname.lastname@example.org (Marius van Leeuwen) I have an Sony cybershot 505 / 2.1 megapixels digitalcamera. The lens is not removable. And I cannot focus bij using eye-piece projection with the 26 mm eye-piece in T-adapter. Even in the macro set it will focus not closer then 80 mm. With my old videocamera it works perfect, you just put the lens of the videocamera aganst the 26 mm eye-piece, but the resolutie and the picture is not so nice. Do you know if there is a solution with a cybershot 505. Or did I bought the wrong camera and must I wait till there is a mirrorreflex digitalcamera with the possibility to remove the lens and with enough pixels? Thank, Kind regards Marius van LeeuwenMike here: Focus the camera lens for infinity (normal mode, not macro). Focus the 26mm eyepiece for your eye (using a bright extended object like the Moon or a terrestrial scene). Place the camera lens as close as possible to the eyepiece. You may have to change the angle slightly to ensure the light from the eyepiece enters the camera lens. If all you see if a small dot of light in the camera LCD (assuming this model has an LCD), then the camera lens is too far away from the exit pupil of the eyepiece. If the camera has a zoom lens, trying using it to get the lens closer to the eyepiece. This does take some experimentation but hopefully it can be done.

Subject: ETX photography Sent: Tuesday, May 9, 2000 11:11:31 From: email@example.com (Blumer, Todd) I found your web site, and have a question. Can one do photography with a digital camera through an ETX, not using eye-piece projection? I have a T-adapter for my Nikon Coolpix 950, and a T-adapter for my ETX. It seems, though that I must have another lens in the mix, correct? I cannot just thread the T-adapters together and expect it to work (I get a dark picture with a bright spot in the middle, the same as if I look into the rear hole with my naked eye. Is there a lens that will work for this setup? Thanks. -- Todd Blumer (firstname.lastname@example.org) Marconi Communications +1.724.742.7828Mike here: What you are trying to do is Prime Focus photography. For that you have to remove the camera lens and image directly onto the camera's focal plane. So, unless you can remove Coolpix lens, you're out of luck. The only alternative is to put an eyepiece into the light path and then you're back to doing afocal photography.

Subject: Re: Re: ETX Sent: Friday, May 5, 2000 18:58:46 From: email@example.com (Paul Goelz) I'm oscillating. I like the idea of the ETX, but I'm afraid it is a bit small for me. However, anything much bigger defeats the portability part of the equation. In the end, I am coming to realize that there isn't much to look at right now other than the moon. One main use would be to introduce people to the wonders of the sky at music festivaI attend. I have in the past taken my 8" but it is a lot to travel with. The ETX would be a nice choice except that all the gas giants are hiding now and the pickings are slim for "wow" things to look at except the moon. I'll probably end up with one... just wish it was a bit better constructed. Actually, I wish the 125 ETX stored more compactly for travel.... I assume you can't swing the tube through the forks? hat must make it kinda long? Ya know what I'm REALLY interested in? I'd like to hear from someone who mated the ETX with the Collins intensified eyepiece. Except for the obscene amount of money, THAT would be an interesting travel combo! The light gathering power of a much larger scope in a tiny package. Paul Goelz Rochester Hills, MI pgoelz at eaglequest dot com Videoastronomy and music web site: http://www.eaglequest.com/~pgoelzMike here: The ETX-90 has been used successfully by users who participated in the Messier Marathon. So, it is not just the Moon (and Sun and planets) that can be seen. The OTA does go between the forks, but only one way (pointing towards the zenith). That's true of all ETX models. I've wondered about the intensified eyepiece myself.
Subject: field report Sent: Thursday, May 4, 2000 19:25:38 From: firstname.lastname@example.org (Edward Mosser) I made it out a couple more times recently and had pretty good success. With the moon starting to come back it will be awhile before I return to the backyard. Lately I have enjoyed going out at dusk and enjoying the transition to darkness. What a great time of the year. April 27th found me outside at dusk and I started on the easy double Gamma Leo. Next I moved up about 3 degrees to Zeta Leonis plus 35, 36, and 39 Leonis. Nice pleasant grouping of stars. It is not a binary system, but hey, I am no double star snob. NGC 2392 is a planetary nebula in Gemini which is easily located and observed with the 90mm ETX, even in suburban skys. It is not star like but a small disk - easy to see why they are called planetary nebula. Jump off of delta Gemini to a group of stars SW and follow your star chart. 90 Leonis is a very nice triple system. I spotted the 9th mag "C" star at 96x (2x barlow with 26mm). 88 Leonis was resolved @ 48x. It has a 9th mag companion 20arc seconds away @ 340 degrees. Denebola is always a treat. It's binary companion is wide 264" at 204 degrees. Leo is just a great constellation. Last year I was pretty bored with it, as I couldn't spot any galaxies, but the doubles are just great and M65/66 are do-able with the 90mm. Why scanning around I stumbled onto an old friend from last year M53. After looking at faint galaxies all spring, the 7.79 mag globular was a treat. I searched for NGC 5053, which is a 10th mag globular about 1.5 degrees away, but couldn't locate it. However, my disappointment was shortlived as I easily located and observed M64. Couldn't find it last year. A year of observing really improves your ability to see. On May 2nd I went out for an hour. Started with 15, 16, and 17 Canes Venatici. The three 6th mag stars for a triangle and are all about 15 arc minutes apart. Revisited M94. My son turned on his bedroom light and that took care of any detailed observing. Still a "fuzzy patch"! 2 Canes Venatici is an easily resolved double at 48x. It is 11 arc seconds @ 260 degrees. I didn't have anyluck with Struve 1624 and 1632. The clouds started coming in and I was thinking about the cherry cream cake inside...with Diet Coke. Ed Mosser

Finally got some time and skies to take out the ETX last weekend. Took it to our observatory and set up to show some members what it would do. I set out to do some doubles in Ursa Major, Draco, and Bootes. Started with Mizar, then Dubhe, Kappa and Iota Bootis, I-25 and Struve 123, tried for 78 Ursa Mjoris but no luck. The members were startled by the crisp ,sharp pinpoint star images and the ability to break apart the doubles. What really got them was the tracking ,went in the lab and had coffee, came back out 35 minutes later and Dubhe was still in the E.P. Then came the clouds !!

Subject: ETX/TELRAD/45° prism Combo Sent: Monday, May 1, 2000 21:06:14 From: PlasmaBeast@aol.com I would like to send along my comments on the ETX ra ... The combo of the Telrad bullseye finder, the 45° prism, and a 2x barlow & 26mm eyepiece is a real easy way to love the ETX. that combo offers a fine 112x @ 1450mm image, with basically no eye strain! M42 M31 M57 M17 M18 M7 M22 M45 Ngc869 Jupiter Saturn Mars (when its close) Uranus Neptune & the young Moon are my usuals with the ETX. I did observe the triple moon transit over Jupiter as first light though, followed closely by the Saturn occultation in Dec 97. I live in SW Utah on the grand staircase between the Grand Canyon, & Bryce canyon, the sky here is dark as it gets, in good weather. Contrast & detail offerd by the ETX optical coatings are better than some broad band filters, for OIII/HyB emmissions, & on the Jovian Planets...The ETX offers a fine view of star clusters useing the 45 prism, & 26mm eyepiece without the barlow too! Properly allowed to come to ambience, and in the configuration above, the ETX compares in many ways to a 9" Alvin Clark refractor, an 8" SCT, & the Questar 3.5" for image quality!
