You already have the manual. Take the scope back and get a replacement.

What a pathetic answer. You twist & turn the lens to focus the scope, you DO NOT pull & push !!! And of course you take the cap off the top!!!

How the specifications of telescopes is read


First you would look at the construction, a reflector or a refractor.



The first has at least 2 mirrors in it, and comes in several sub-types. The cheapest to begin with is a Newtonian, very cost effective. You can recognise these as having the eyepiece at the front end of the tube.



http://www.365astronomy.com/images/10237-skywatcher-quattro-12s-imaging-newtonian-telescope.jpg



Newtonians however have to be optically aligned (collimated) every so often to give a sharp image. This is simple enough when you learn how, but some find it a pain.



Refractors have no mirrors, only lenses, and you can recognise these as having the eyepiece at the rear of a longish tube. They don\'t need regular collimation. The better ones have more lenses in them, and in larger sizes are very expensive.



http://www.astronomyalive.com.au/media/catalog/product/cache/1/image/5e06319eda06f020e43594a9c230972d/7/0/709eq.jpg



The next spec you see is the aperture, or diameter of the optics. It is the diameter of the main mirror or lens, and governs the light gathering power of the scope. If you live in the city, there is no point to having a huge scope, as it only gathers lots of light pollution. If away from towns, a large scope will pick up faint nebula. 100 - 150mm (4"-6") is a good starter size.



Then you see the focal length (FL) quoted. This is the length of the light path in the scope. In a reflector it is folded up, and can be quite long without having a bulky tube (OTA). In a refractor it is straight, and so is limited in amateur scopes to about 1200mm.



The focal length governs the magnification you see, but only in partnership with the eyepiece (EP). These are interchangeable



http://www.atozastro.com/my_equip/eye_pieces_set.jpg



and each has its own focal length. The magnification is the scope FL divided by the EP FL. So a 1200mm FL scope with a 25mm EP gives a magnification of x48, which does not sound much, but is good for a sweeping view of the Milky Way. EPS range down to 4mm commonly, so there is wide choice.



There is not space here to discuss the mounts, but start with a robust AltAzimuth (AZ), say a Skywatcher AZ4. Another popular mount is the Dobsonian, confined to Newtonian reflectors.



I\'d urge you not to get a cheap department store scope. These are absolute junk with plastic lenses and poor construction. Depending on budget, get an affordable refractor first up, (so you don\'t have to fiddle with it much) with some Plossl type EPs (cost effective) like a

Where would I get a indepth manual for this telescope please? It's a Skywatcher 13065EQ2 My husband got it for his birthday and it seems a lot more complicated than he thought! Any help would be...


Well you bought him an equatorial mount that must first be polar aligned in order to be used properly. A local Astronomy club can also help you figure out the scope.

Skywatcher manuals are on this web site--

I do not have assembly instructions or how to use the telescope, for my 18 year old. any downloads would be most helpfull. thanks.


Here are all of Meade Telescope manuals--

http://www.meade.com/manuals/index.html

Find one under either REFLECTOR or REFRACTOR that is similar to your scope. There are no manuals available for National Geographic, but they all assemble in a similar fashion.

I just bought an Optus 553 telescope and the instructions are not in English. Where can I get operating manual and set-up instructions please? I live in Spain.


Sorry, but that is NOT a major brand of telescope like Skywatcher, Meade, Celestron, Astro Physics, and so forth.

You will not find a manual anywhere. Try to locate a local Astronomy club and get the members to help you with the scope. Most clubs welcome new members and will help them.

Looking for instruction book for skywatcher sk607AZ2 christmas present for keen 10 y/o ignorant dad


This is a simple refractor telescope. They all assemble in the exact same way. Meade has a similar telescope and maintains a page with all of their manuals. Here:

http://www.meade.com/manuals/TelescopeManuals/Refractors/Meade70AZ_AR.pdf This one is almost identical to your telescope.

Seben 150-1400 telescope


This is a pretty generic Chinese made 6" Newtonian reflector. The one's I have sampled produce excellent images. Celestron has a great online archieve of its manuals. This scope is similar to their C150-HD Newtonian Model #31056. The manual can be found here:
http://downloads.celestron.com/Manuals/telescopes/c150hd_g8n/c150hd_g8n_manual/c150hd_g8n_manual_0802.pdf

Google "beginning astronomy" and you'll get a quartr of million hits. Good over view here.

and here:

While you are there get a subscription to Sky and Telescope or their other publication aimed at beginners, Night Sky.

Find a local astronomy club and join it.
