How many pages does it have. Any information would be appreciated. Does anybody know, by comparing the first one (hyperlinked above) to the second one which they may have? There may be more on the Astroscan instructions but that would take some digging time.

Both the color Richard Berry manual and the Astroscan 2001 Edmund manual are entirely different. The 'Astroscan 2001' has much better technical detail of the scope. The 'Using Your Astroscan' by Berry is more oriented towards application with a lot of general viewing information. I doubt there is any source for these now, and your likely only going to find them free floating by luck. I've talked Kinkos into making copies of other pamphlets by matching the paper and double printing on double sized sheets. Then folding the sheets made sort of a duplicate copy. The three items shown are stapled booklets with dates all over them and I doubt they would touch these for duplicating, but they might. It would be an indefinite time frame for me to scan or copy them. I'll likely forget, no time now, I'd have to figure out the scanner thing all over again.It seems that the pamphlets changed their covers (at least) over time.It seems that the pamphlets changed their covers (at least) over time.

The Astroscan with the tripod bracket and skinny metal tripod, well that whole thing is totally foreign to me now, I can't remember that tripod. I know the pictures of my place, but without recollection it is a strange physiological sensation to see them. No problem, it's a situation I'm somewhat accustomed to now, it's kind of a buzz. Yep, the covers as well as the contents of the booklets have morphed over time and probably with every revision to some extent. Any revision in any series would suffice for collectability to me. I wouldn't worry about having to have the first version released. I used to take the booklets to Kinkos, make sure they could duplicate it, then I'd carefully remove the staples and have the paper matched for type, then two sided printing on the double sized papers. It was very time consuming and I'm afraid those days of paper work are just going to be behind me now. The 'Astroscan 2001' has much better technical detail of the scope. The 'Using Your Astroscan' by Berry is more oriented towards application with a lot of general viewing information.

It is also was one of the most controversial telescopes made (at least that wasn’t an outright scam or waste of people’s money). A simple search for the Astroscan in Astronomy forums reveals that the little red telescope has many detractors, and many defenders: PC wars on newsgroups, where PC advocates objected to people buying things that might not have been as powerful or economic as what they used and Mac advocates vehemently defended their choices with rabidity and dared to be a fraction of the marketplace. Of course, in this case the scale was much smaller. Why was it so different than other telescopes. What happened to it. Why was it so loathed and loved. I shall try to answer these questions with my limited experience of having worked for Edmund Scientific for the last couple of years that the Edmund family owned the Scientifics division (The Edmund family still owns the Industrial Optics portion of the company). The idea was to make something that was easy to use, easy to transport, and wouldn’t look out of place in a 1970’s Living Room. Given that in that era almost all commerically sold telescopes were tripod mounted things that took up a lot of real estate when set-up this was bit of a sea change. The optical system was developed so that the customer would not have to do any maintenance (or collimation) that reflectors often required. It was also designed with an optical window so that dust and other debris entering the tube would be minimized.It initially did not have any aiming mechanism as it being a rich field telescope was assumed to be good enough to along (it wasn’t). The problem was mostly aesthetics: Any aiming mechanism would spoil the clean lines fo the Astroscan’s body. Eventually a sheet metal aiming deveice was developed that helped.https://congviendisan.vn/vi/boss-br-900cd-user-manual Later models, as shown in the above picture, had a red-dot finder added for aiming. Hardcore amatuer astronomers were grumpy that so much effort was put into a telescope that wasn’t aimed at their needs, and didn’t address what they felt was ideal in a beginner telescope. The validity of their arguments continues to be debated to this day. Being a rich field telescope with only 1 eyepiece included it had what seemed like an anemic 16x magnification. This was in an age where retail department store telescopes were sick with ludicrious claims of unattainable magnification (640x!!!!). Edmund had hoped to have their new telescope sold by wholesale as well as through their famous catalog, and seeing this stylish but-low-powered telescope next to the fake claims of cheaper telescopes was a hinderance to those long-term wholesale plans. That said, some people loved it, including the founder of Orion Telescopes, Tim Geisler. The exact numbers are unclear but in its lifetime it is assumed to have sold around 90,000 units, making for around 2400 units per year, which is good numbers for a company that does not exclusivelty sell telescopes. But this was to cause a few growing pains for the Astroscan. For one, the 70’s were an era of major inflationary pressures and keeping costs down just was not possible. At some point in the 80’s a decision was made to move production to the less expensive Japan. Production began in that nation after many, many, many long meetings and trips by the senior brass from Edmund. In any case, production costs in Japan rose steadily over the years to the point where, when combined with the overseas shipping costs, it was no longer economical to produce the Astroscan in Japan. Production was returned to Barrington, NJ in the USA. It hadn’t had much attention paid to its design in years (the last major changes happened when the production was moved to Japan).http://alroglobal.com/images/carver-tx-1-11-manual.pdf There were other issues: The Astroscan screamed 70’s design, but not loudly enough to provoke nostalgia.Edmund had introduced a series of lower-cost beginner telescopes to work as a fleet with the Astroscan as the Flagship, but none of them garnered much success. The wholesale program became a morass as other retailers undercut Edmund’s pricing, or even broke up the telescope into its component parts and sold them individually to get around any Minimum Advertised Price policy Edmund might introduce. The wholesale program also did not account for retail inventory needs, so telescopes were often shipped out to other retailers when Edmund’s own retail telescope sale needs were not fulfilled. The most visible of which was the Bushnell Voyager It was immensely heavy compared to a traditional astroscan and had just a piece of colored tape to cover the seam between to the tube and the ball. The telescope famously used the rack end of a zip-tie for its focuser rack. Oddly enough the optics in the telescope were not bad! Message boards were inquired, costs assessed, ideas explored, et cetera. The optics would be changed to more modern and less costly counterparts. A mechanical engineer was sourced to develop and improve the focuser. Sourcing parts from Asia was explored to reduce cost while still keeping the production in the USA. The overall plan was to get the Astroscan competitive in the new playing field, to answer as many of its criticisms as we possibly could, and overall revitalize what had become a dusty corner of the world’s telescope offerings. How much would the new Astroscan differ from the old one. We’ll never know. All work on the New Astroscan Project ceased. The quality was a bit more concerning and the classic RKE eyepieces were replaced with generic Plossl eyepieces (partly because the Edmund family still claimed the rights to the RKE eyepieces and sold them in their Industrial Catalog for years afterwards). The mold used to produce the Astroscan body broke. That is all we know at this point.ScientificsOnline decided to not produce a new mold. Instead they introduced the Astroscan Millenium, a mini Dobsonian with similar optical characterisics. The irony here is that the StarBlast was designed to match the optical features of the Astroscan. Welcome to your closed circle. Yes, they did go out of collimation despite the claims, and it was very hard to get them back.They had a great contender with the Astroscan, but all of their other models were not as able to support their costs of development. While some of the telescopes Edmund made in the 60’s were classics, they would not be able to compete in the modern market. Edmund did not develop an import line of telescopes the way other major telescope brands did. This is not a surprise as the Edmund company found there was more money to be made developing industrial optics than there was in the telescope market. In fact, it is essentially the Astroscan made by more modern methods and suppliers. The kickstarter has ended, however, and it is unknown if production will continue. I was given a used astroscan as a gift years ago so naturally it came with no manual or accessories. Thanks for such a detailed history of this unique little telescope. I like it even more now. Do you know if I might be able to find accessories such as extra lenses, filters etc. Any advice would be greatly appreciated. Thanks. Color filters and light pollution filters thread onto the eyepieces and are also pretty universal. You can find some at our website in the telescope accessories section, but we are by no means the only supplier. I always had a soft spot for that scope. I keep it in the trunk of the car. Easiest scope I’ve ever used. I loved it and was able to view many deep sky objects with a Barlow lens. Took it everywhere that hanging strap was handy. So easy to locate objects that to this day I can’t get used to a standard mount. Interesting to read about it’s history. Sad it’s no longer made what with the retro craze now.

But try to get one still made in the USA. They were better. I still have my Astroscan from the 80s and there was never and will never be a more fun and practical scope for the pure pleasure of observing wide fields at f4.2. The only difference is that the China model was metal and very heavy. I have no idea what these are made of. I hope that your assessment is wrong, but this does seem to be a long time being made. I was a little concerned with the low level of cost for the kickstarter as a mold for the design would eat up a huge chunk of any development money. No word if that has gone anywhere but I did not see them with a booth at this year’s Toy Fair. I was noticing the “prototype” seems like an actual astroscan, painted. In any case, maybe the story will have a positive end, but I do not think it will be a rebirth of the astroscan. In any case, maybe you have seen this, Jerry Oltion built a scaled up tribute to the astroscan, including a clock drive: When did that take place. It’s not mentioned but I believe the early versions used Japanese optics made by Carton. This is also when they went from having RKE eyepiece to Plossl eyepieces. I have a “made in Japan” Astroscan, serial number 9049652. Do you know how to date it? I am unaware of any listing of serial numbers and I suspect the Edmund Company long discarded any such listings when they sold off the Scientifics division. It looks like the first 2 digits on Japanese serial numbers refers to the year of manufacture, so mine must be one of the last made in Japan. Notify me of new posts via email. Then watch it fly with electricity you generated.Find our writings by category. The finder mount is broken. In addition, the optical performance is poor due to a damaged secondary mirror mount. Unfortunately the telescope is slightly but permenately out of collimation and is not suitable for hig power viewing, but it works fine with the provided eyepieces. A low power eyepiece (16x) provides a three degree angle true field of view and a medium power eyepiece provides 25x. The Astroscan provides good views of large star clusters and nebula, such as the Double Cluster, the Andromeda galaxy, and the Great Nebula in Orion.It will show Jupiter and it's moons, but does not quite resolve Saturn's ring system.

Ex long Islander I would love to attach my Nikon 7000 to the telescope to take pictures of the sky. In looking around on the web, there seems to be no clear instructions on what to get, or even how to attach a camera. If it will work better, I also have a Sony a6000 which is much lighter, or I am even willing to buy a camera for this use only. I am open to any suggestions Try calling Edmund Scientific.I would suggest devising some sort of auxilliary bracket that would bear the weight stresses. Once the lens barrel threads become stress deformed, there is no going back. The Sony a6000 is 43 mm, I seem to recall and the thread depth is only about 4 or 5 turns. Not a great deal of metal to support the body weight stresses, I would guess. I know more about this then my typing might show but still my camera is a D80 and camera with a lens that comes off would do.I would love to attach my Nikon 7000 to the telescope to take pictures of the sky.

Holding the camera above the 23mm eyepiece of my solar filtered ETX-90. Gee, imagine if I'd actually made a real bracket to hold the camera still. Google has a gazillion pictures of it. The operator moves the rig around, aims and tracks by hand, with no clamps, handles, locks, dials or other telescope trimmings. I don't recall there being a finder scope either, but maybe a gunsight sort of thing. I guess it depends when you bought it and with what accessories. There are still accessories made for it specifically, including an eyepiece projection attachment. Of course you can hook up a camera with T-mounts and eyepiece adapters and the like, but I doubt the designers intended the Astroscan to be an astrophotographic tool. Exposures must be very short, as the scope has no tracking mechanism and objects in the sky are generally in motion. Here on the Hog we try to keep a positive outlook, and I wouldn't discourage some inexpensive experimentation, but I'd keep your expectations really low. The device is made to be a portable wide-field viewing device and photography is usually undertaken with a heavier scope with a mount that moves in line with the motion of the stars. Google is your friend in these matters. Best of luck! They will take 480x640 res pics and video and display live view on a laptop for fine focusing and adjusting the camera through the laptop software. You can load a 2x or 3x barlow lens in front of the camera and after the eyepiece to increase your magnification.

( show quote ) With the planets, however, you need at least 160x to get a good view of them and at that magnification they move through the field of view in seconds, so it's very difficult to take pics unless you are using a tracking motor on your mount which will keep the planet in the field of view.

Robert Evans 1.0 out of 5 stars Cheap Chinese plastic counterfeit. No instructions. No paperwork inside or on the box, either.Attached to wood stool is betterNever went anywhere that didn't have it in the trunk of my car somewhere. Dropped and banged many times, but always worked. I gave it away after college, but bought another when my kids were young. Took it to Death Valley with my kids and saw the rings of Saturn, the moons of Jupiter, and dozens of other wonders up there. Seeing the rings of Saturn can occupy an entire evening. We spent many hours sitting on the top of our camper at night. Magical times. I had a Japanese exchange student stay with us. I introduced her to the Astroscan and couldn't get her to go to bed at night. She pent hours on our deck searching the sky. This isn't some advanced scientific marvel. The eyepiece adjustment is clunky and the star finder is crappy, but they work. It's 5-star rating comes from it's portability and the simplicity of operation that makes viewing an easy pastime. I have used expensive telescopes in the past, but seldom wanted to go through the ritual of setting the damn things up. My kids would never sit still for that. This thing? Put it in your lap and look. That's it. I even used it to sit on hilltops to watch fishing boats miles out at sea to see if they are catching salmon. They were upside down, but if their rods were bending and the nets were out, I bought a ticket. Even took photos with it. Great buy. A lot of nostalgia tied up in this ugly, red ball.He liked the tripod because it is light and is collapsible, so it made it easy to pack. His one complaint, which is also my complaint is that the tripod is wobbly and does not seem substantial enough to support the Astroscan. Its okay if you are using the Astroscan occasionally, but if use the telescope often, I don't think this tripod will hold up. I found the Meade Tripod for the DS 2000 is a more suitable tripod for the Astroscan. The Meade Tripod is also lightweight, but legs and the base of the tripod are more substantial than what is found on the Astroscan tripod.The telescope is light The telescope is light, has a wide aperture, is very easy to carry a round without damaging any of the glass. Comes with a base, strap, two lenses, and a dust cover. When I had it as a young kid, it also came with a tripod mount but apparently its not sold anymore, the base is great to sit on a desk or store anywhere there is a flat surface. I took this telescope everywhere and I could easily sling it over my back with the straps and go somewhere and not worry I was going to break anything. Plus I used it for looking at wildlife or stars or just whatever was far away. I plan to buy another one for my girls after my parents got rid of mine when I went to college. No need to worry if you have a klutz or awkward kid in the house, this will be their best friend when it comes to seeing the stars or exploring the wild. This should be in the classroom because it is so safe for young and old and so great with its big aperture a with the large view field. Buy and enjoy. Don't listen to the stupid nay sayers. They apparently don't understand what kids enjoy and young astronomers need to learn about the night sky. Ok it also comes with glow at night constellation maps. very handy. Buy it and you won't regret it. Just tell them the kid from Kentucky sent ya.
