    Nothing has changed W/ my primary question!
    Re: I want to know WHERE I can aquire a MANUEL for a HORIZON - MODEL 4780 Telescope.

  • bgrattel Oct 03, 2010

    It's diameter is D=60mm / f=910mm. There is a Horizon name plate w/ the same 60mm F 910mm also 45X 73X 152X 225X 90X 146X 304X 450X & Mod. 4780. The eyepieces are: S.R.4mm,H5mm,H.M.6mm,H.M.12.5mm,H-20mm,6X,Meade OR9mm Multi-Coated also a 2X Barlow lens. It was built in Japan and apparently a souce of embarressment as the my trace so far hasn't yeilded any clues ( as per your reply ). The wooden tripod is in horrible shape though I have no misgivings that I may engineer something for it or simply purchase a good camera tripod. When I first saw the Meade refractor scopes I was sure that I would find this one as it looks very much like them, though I've come to realize that all refrators look pretty much the same. From reading-n-various replies from the astronomy forum that I subscribe, I've figured the focal length is 910mm and it is a 2.4" apreture, or 60mm which I'm assured is a good starter scope ( which I am ). Recently I purchased a Celestron AstroMaster 90EQ it is a 90mm / f/1000mm refractor and am getting acquaited with.

    My objective is to restore the previuos mentioned scope. I mean, some one took the time and effort to design and engineer the scope-n-that as far as I'm concerned, merits restoration and am in hopes of getting a manuel in order to start the process.

    Please reply.

  • bgrattel Oct 06, 2010

    Do you have any futher answers to my prime question ( re; Manuel for a Horion Mod. 4780 60mm f/190mm telescope) ?

  • bgrattel Oct 07, 2010

    Any expert that CAN help,I will be over joyed.
    I need POSITIVE info on where I may acquire an op. manuel for a Mod.4780 Horizon 60mm w/ f/910mm telescope. There are various other eyepieces that frankly need not be mentioned presently. I have resolved that the scope is an obvious embarressment to the manufactor,or it seems that way.Never the less,my intent is to restore the scope.My position is that some one took the time and effort to produce the scope-n-that alone,to me,merits restoration.
    Please reply:bgrattel@bellsouth.net

  • bgrattel Oct 07, 2010

    Thank you for your reply,though again,I am disappointed.Never the less,I am resolved to forge on.Together w/my resolve is the fact that some one,some where took the time and effort to produce the scope,no matter the "cheapness" and this scope may be an embarressment to them because of the "quick buck" tactic.However,my intent is to restore the scope-n-I believe that the effort to produce it,(at least to me) merits restoration.I am a member of and closely follow Astronomy magazines forum-n-that,doesn't mean that I think myself any where near the very brigtht people that it has been my honor to converse with.They are bright but not snooty.

  • bgrattel Oct 07, 2010

    I have for days tried to acquire a ops. manuel for a 60mm-f/910mm Mod.4780 Horizon telescope.Be advised that I gone thru a multitude of web pgs. as well as various 500 word games-n-am hitting the brick wall.This scope was produced in a "quick buck" tactic-n-is apparently a bit of an embarressment to the manufactor,none the less,my intent and hope is to restore the scope as it is in a deplorable state.The "heavy hitters"of today that sell intruments that vastly put this one to shame w/their excellant optics-n-all,had to start some where.The FACT that some one,some where,put in the time-n-effort to produce the scope is in my mind,merit for restoration,no matter how much dung is dumped on it.I need an EXPERT to help trace the scope back to it's roots.

  • bgrattel Oct 07, 2010

    Please accept my most humble apoligies,I meant no insult.The word "snooty" was,in this context,meant to discribe some,I am certain you as we all have,had the unfortunate occurance to endure.Please for give my absolute ignorance w/ the proper use of words to describe what I intent to say.Thank you very much for your effort.

  • bgrattel Oct 07, 2010

    Thanks for your reply and the web pgs. sadly,none of them helped nor answer my questiion.

  • bgrattel Oct 07, 2010

    Thanks for your reply and the web pgs. though none of it helped.My question wasn't how to use a scope but rather the source to acquire manuel so that I may restore the scope.

  • bgrattel Oct 07, 2010

    This my third attempt and I'm hope to get some results.I'm looking for an ops. manuel for a Mod.4780 Horizon telescope it is 60mm-f/910mm refractor.

  • bgrattel Oct 07, 2010

    Where may acquire a manuel for a 60mm-f/910mm Mod.4780 Horizon telescope?You are the third expert that I've contacted.They have,as I have scoured the web pgs. w/ no luck.Thing is,this scope was built by some one no matter how cruddy-n-I want to restore it.

  • bgrattel Oct 08, 2010

    Ginko,thanks for your response and your additional files they are indeed everything one may need for basic understanding and use of the refractor.However,I suppose that my problem is that I do not relate properly or exactly what I am in search of.

    Another part of the problem is that,I maintain that some where there has to be more substantual info. on this scope.It is real.It has Japan on every one of the accesserties.It has all the before mentioned + the name Horizon on the manufactors label.

    Surely,some ones archives has the info. or at least contact info. to uptain that info.

    By the way,I own a Celestron 90EQ AstoMaster 90mm-f/1000mm refractor and am versed in it's use,therefore,I have no use for further instruction in that regard and is not what I've asked for.

  • bgrattel Oct 08, 2010

    Thanks ginko,I'll give the web pg. a peek-n-see what I can-n- let you know.

  • bgrattel Oct 09, 2010

    Now this sounds like what I'd hope for as the promo pg. declared-n-I'm feeling a bit more confidant since our lastest posts.
    Thanks!

  • bgrattel Oct 09, 2010

    It is my hope to trace the scope to it's original source-n-w/that aid,restore the scope.I realize it isn't one that is accepted w/o destain.The FACT is that some one,some where took the time-n-effort to produce the scope-n-that,to me,merits restoration.If you aren't firmiliar w/ the scope,it is:Mod.4780 Horizon 60mm-f/910 refractor.These FACTS clearly appear on the veiw tube as well as all the accesseries.It is a Japanese made scope.
    I have no need for instruction on the use of a refractor as I own a Celestron 90EQ AstroMaster 90mm-f/1000mm refractor and am versed.

  • bgrattel Oct 11, 2010

    I don't recall if I've posted you or not,if your following the posts you'll see there are a few. I want to find the manufactor so that I may restore the scope.I don't need instruction or similar,I own and am versed on the refractor.I just want to trace this one by to it's maker and restore it.

  • bgrattel Oct 11, 2010

    Hi ginko,please forgive my abrupt "reaches" it is due to the fact that I am at times over anxious to uptain results and in no way your fault.The fact is,you of all I have posted,were on the same page.This is the reason that I chose to post my question here in the first place.My hope is to contact the scopes maker and through them restore the scope.The limits of the instrument is not the point to me,anymore than someone who restores an old Model T.
    Please respond.

  • bgrattel Oct 20, 2010

    I'm trying to trace the maker of a Mod.4780 Horizon 60mmf/910mm refractor telescope.

  • bgrattel Oct 23, 2010

    Thank you for your reply.The only info. I have for the scope is as follows;Horizon Astronomical Telescope 60mm f/910mm HOC Mod.4780.All of this appears on the manufacture label on the view tube and ofcorse the display made in Japan.

    My hope is to trace the scope back to it's maker and therefore restore it.

    I have posted a couple of scope makers there with no results and that may be due to in part that I do not understand the correct protocols.My hope is to contact some one who does and that will be the only satisfactory solution.

You posted this without detailing your problem. That brand (Horizon) is unknown and probably an imported telescope made in Asia.

There is an "Horizon" hobby shop vendor located here:
http://searchplay.horizonhobby.com/index.jsp?N=5735&sid=12BCB4EE4C10

But they sell different brands of telescopes. You need to be more specific about the telescope and the problem you are having.

  • Joe Lalumia aka TelescopeMan

    Only one. Post your question on the www.cloudynights.com Classic Scopes forum. You will need to join to post the question but it's free. Maybe someone there has heard of this scope??? Personally I have never heard of this brand, and internet search also finds nothing. I doubt that anyone has an actual original manual.

Hi.

Horizon is not a known optic brand (Event Horizon is, but model does not match). The telescope is a refractor 60x910 (see Refractors ). This kind of telescopes work all in the same way since Galileo invented them.

The refractor is usually sold with a leaflet contining minimal instructions. Original leaflet for this refractor is not available. I am posting relevant documentation. I have been an astrophile for several years. This should be enough to use the telescope:


Manual: PDF file - orion® observer™ 60mm aZ

Manual 60mm Refractor Telescope

Telescope how-to instructions, help and tips

As said, the manuals above should apply to your telescope. In case you repute this solution helpful, please don't forget to accept.

Regards.

Ginko.

    Horizon optica japan madel instruments are rare. They are not for sale anymore, sometimes there are binoculars for sale in second hand market. This is the first refractor I have heard about.
    I do not know the name of the manufacturer, I think Horizon was the name of the line or division.
    Horizon Optical is a name used also by China and UK based companies, that is reason why I thought you were talking about a basic refractor (even if it is 900 mm).
    THe only mention I found on the Internet is this forum, try opening a new thread or cueing up a comment in the old thread, I am sure they are talking about same company's product: Telescope Reviews: Rare Horizon 15x80 binos.

    I wanted to add that I found an astronomy forum dealing with same problem and same model (I won't be surprised if post was yours.

    Ginko Oct 11, 2010

    Hi.

    There is no registered Horizon company currently manufacturing telescopes or binoculars in japan. There are second hands optics for sale on web, but they are rare.

    That means that the original company has closed.

    There are more Horizon optic companies, in India, UK and Canada, but they are not related to the producer of this telescope.

    This is the outcome of several days search that costed me time and a bad feedback.

    Regards.

    Ginko.

    As said, there is no manufacturer info avail.

    Manufacturer is probably not even called Horizon. Horizon may be the series, or the optical .

    The only way to tracking a contact for manufacturer is writing in forums like the ones I gave you, where one of the poster states he/she owns an Horizon piece. Ask the owner if he has an instruction leaflet, there you will probably find a contact to manufacturer or support. Ask for the contact.

    Several companies sold optical series called Horizon.

    Here one of the forums, there should be another one in some of my previous comments: Telescope Reviews: Rare Horizon 15x80 binos

    I wanted also remind that the refractor is something more than a tube with good quality Japan-made optics. When original parts are not avail, repair can be done replacing damaged Optics with good brand ones (eg.Zenith), or adapting parts.

    Also Swift Optic makes a series called Horizon. Some of models were Japan-made. I dont think that they are related, but you can call them and ask if model had been made by Swift, that won't cost anything: Binoculars UK- Swift Horizon Binoculars.

    Regards.

Hi. Sorry but I could find nothing about your scope with Google and three other search engines. It's certainly one of those intruments crafted in the Far East and sold under a variety of brands. Or maybe it was made in the West but by a manufacturer that no longer exists.

Sorry we can not help you find a manual.

    Start with the lowest magnification eyepiece. It has the largest number, perhaps 25, or 30 if you're lucky. There's a good chance that it's the only usable eyepiece.

    Then look for an easy target. During the day, that might be a building or a telephone pole. Never point it at the Sun. Point in the general direction, and look. There's a focuser knob. slowly turn the knob so that the focuser goes in or out from one end to the other. When the image gets into focus, stop. If you overshoot, go back a bit.

    At night, try the Moon first. It's big and bright. Do the focus thing. All objects should be at about the same focus at night.

    Once you've mastered the Moon, check out Jupiter or Venus in the early evening sky in the west-southwest.

    Most telescopes are made the same as long as they are not the computerized ones.

If your question was "Where can I get a manual?" then unfortunately the reason you have no answer is that there doesn't appear to be one in the public domain which is available online.

I've never heard of your model, but as there are hundreds of factories which produce generic models which subsequently have no-name branding applied it's unsurprising. Please describe your telescope fully: its diameter, focal length, mount, finder, tripod, eyepieces, plus the accessories you might have, and whether its objective is a lens or a mirror. Also state if there's any identification as to which country it's made in. These details will help to identify whether it's been supplied under a more familiar brand name such as Meade, Tasco or Bresser in which case they may have a suitable manual.

Note that many telescopes simply don't have user manuals to start with, as they're often aimed at experienced users.

    Nothing much to report unfortunately, I've been asking around quite widely though. Many claim to have heard of it: the 60mm objective with vastly over-magnifying eyepieces for the objective means it's typical of the kind of poor-quality "starter" 'scope which experienced astronomers won't touch with a bargepole and which beginners buy as it's very cheap but then get put off by the poor results. Just like the awful tat which Tasco tend to foist on people. I've heard from one lady who "thinks" she owned one and she was "pretty sure" that there wasn't anything other than a pamphlet with the most basic set of assembly instructions and a basic description of what each piece was for. Given my lack of success it suggests that the information which you require is simply not available, sorry.

  • Obertelli
    Obertelli Oct 07, 2010

    I fully understand your disappointment and only wish that I could have been of more assistance. There was nothing in my reply which was intended to be "snooty" about your 'scope, and in general I find that astronomy clubs welcome all who are interested regardless of equipment or lack of experience. The only reason that cheap 'scopes are generally avoided by them is simply due to the poor optical and mechanical quality although a recent 60mm Bresser Meade refractors has been very impressive for the price. My own example only cost me £60 complete with an equatorial mount and tripod and once I replaced the unacceptable eyepieces and upgraded the tripod the performance was transformed. Good luck with your restoration, I sincerely hope that it goes well and that you end up with a useful optic.

How do I aline the finderscope


Telescope manuals recommend that you do this in daylight, by pointing the scope at an object on the horizon and adjusting the finder to match (never point a telescope toward the Sun!). Use the lowest power eyepiece you have (the one with the highest number). Once you have a tree or mountain peak in the center of the main scope's image, you can then adjust the screws around the finder scope to get the crosshairs (or red dot) centered on the same object. It is very difficult to do this job in the dark, especially as objects in the sky are constantly on the move.

How to calculate 24124 mod 19937 in casio fx-991Ms calculator


The MOD function simply returns the remainder that is left over after dividing the two numbers.

In this case, its possible to see quite easily that only 1×19937 can be taken from 24124 before the remainder is less than 19937. The MOD function is therefore the same as 24124 - 19937 = 4187.

In cases that are less obvious, do the division, ie 24124 ÷ 19937 = 1.210011536[34]
[The last two digits are hidden on the display but still used in subsequent calculations].
Then obtain the fractional part by subtracting 1 to give 0.210011536[34]. Then multiply the answer by 19937 to give 4187. Assuming that you haven't cleared the screen between each section of the calculation, the screen will show "Ans×19937 [=] 4187".

I am struggling to set the telescope us as the


Is it like THIS telescope?
http://www.opticsplanet.net/konus-knonusmotor-130-telescope-1786.html

The focuser mechanism is at the FRONT end of the telescope. The Mirror is in the back-end or bottom of the telescope. This scope is on an equitorial mount, which means it must be POLAR ALIGNED in order to work. You can get a rough polar alignment by using the star Polaris (the North star).

We never recommend an EQ mount to beginners. Polar alignment introduces an additional beginner frustration with using the telescope. Read these web sites to get an idea of polar aligning a telescope.

Their are TWO knobs on the telescope that control Right Ascention and Declination movement. Declination IS your latitude, so the angle must be set to where you live. I am at latitude 32 degrees N --- so the angle is 32 degrees, which is where Polaris is above the horizon.

Like others, I have trouble seeing stars. There is an obstruction, an image of the secondary mirror which obscures most of the star. Is this the spider? Others have asked the same question, but I haven't...


Yes, you are not focusing the telescope properly. When in focus you cannot see the spider.

Put the eyepiece with the largest number written on it into the telescope. Go outside during the day and practice focusing on a distant object.

HOW DO I USE THE TELESCOPE


Hi,

he first thing you will need to know is does your telescope have a polar axis or not, that is, is it intended to track, or is it merely a point and look, or what we call Alt-Az. Alt means altitude and Az means azimuth, where Alt is the distance above the horizon, and Az is the direction in a circle around the horizon. If you have an Alt-Az mount, just skip the polar alignment step. If you have a polar axis, that is, your telescope is intended to track the stars, then find north, and make sure the polar axis is approximately lined up in that direction. It does not have to be too accurate, but make sure it is pointing pretty close to north. If you are not sure where north is, either use a magnetic compass, or try to find Polaris, the North Star.

Thanks.
