Astro Telescopes
Is the Hubble Space telescope aligned like a land based telescope would be polar aligned?
To take astro-photographs on the earth, needs your telescope to be accurately aligned on one axis to the pole star, how is the hubble scope able to take great pictures, is it aligned or does it use some other mechanism?
On Earth, telescopes have to be aligned because they are "fixed" to the surface of the Earth, which is rotating. Thus the "polar" axis around which the scope pivots to remain centered upon the object at which it is pointed. The Hubble, in space, is pointed at it's target without reference to the Earth. Although it moves in an orbit roughly 9000 miles in diameter every 100 minutes or so, and moves with the Earth at a speed of roughly 65000 miles per hour, nothing except some extremely small tidal gravitational forces, counterbalanced by the pointing gyroscopes, moves the Hubble away from its targets.

Brandon's unboxing video of his 102mm ASTRO-NOVA TELESCOPE PART 1
What telescope would you recommend for astro imaging purposes?
I am willing to spend between 2-300 euro. ( roughly 300- 400 dollars).
Are the skymax brand worth considering?
eg these?
http://www.firstlightoptics.com/products.php?cat=30
From the wording of your question I gather that you are new to Astronomy.
If that is the case, especially if this is your first telescope, there is only one sensible recommendation. DON"T DO IT!!
You will become frustrated beyond belief and give the whole thing up in disgust in three months after having spent a good deal of money. ....And fellows like me get to purchase a very cheap "Astrophotography Outfit" from the used equipment ads, which is where yours will end up.
Having said that, anyone with a camera and a very inexpensive Telescope can simply hold the camera up to the eyepiece and with a little practice take some nice pictures of the Moon.
Anything beyond that, requires special equipment, from cameras to mounts to telescopes.
Let me give you just one example if I may.
I am going to use the scope you selected in this example.
The type of scope you mention has a very long focal length and that is part of what makes it a very good Telescope for working with planets.
But even with that telescope, Jupiter would only appear as a tiny dot in your camera's image. You would need special lenses to get a larger image of the planet. But the more you enlarge the image, the more you also enlarge any errors, such that the tiniest shake of the mount or scope would totally blur your image.
But you need a very good quality (read expensive!) mount to be able to point a telescope that steadily and that accurately .
Now lets say you decide to take some photos of deep space objects. Remember the long focal length of this Telescope? This makes for a very narrow field of view where you can only see a tiny part of the sky.But many, many deep space objects are very large and will not fit into this Telescope's field of view at all. So this type of scope is exactly the opposite what's needed for deep space photography.
The above are just some very basic and very simplistic problems to overcome for serious astrophotography. I haven't even mentioned the software required to take and process the images, along with tons of memory required to store the large image files. You can fill up a hard drive in no time with these multi-megabyte files.
I would love to welcome you to the exciting Hobby of Astronomy.!! But the way to go about it, is to start with just plain observing and learning to operate your Telescope and finding your way around the sky. ( kinda hard to take a pic of something you can't find!)
You don't need the aggravation to learn the camera setups, control software and a complicated mount all at the same time.
Please reconsider.
BTW, the type of telescope you have chosen is an excellent scope to start with, it has some of the best quality optics around, but there are less expensive solutions.
But you will find out all the details once you get started, and there are a thousand things to learn. This Hobby never gets boring, that's for sure.
Good Luck !

Everything about astronomy!?
I would like to learn everything about astronomy and also become a member of an astronomy group to observe using telescope.
Who could please supply me with some direction or links?
