@simon the viking I just wanted to give you a few pointers to help you once you get a clear night; forgive me if this is at all patronising as it isn't meant that way.
- While it is light, set up the finderscope on the telescope. Do this by lining the main telescope up on a distant object (e.g. a TV aerial across the street or a distant treetop) and then adjusting the findersope so that it also lines up on the object. You can then use the findersope at night to line up the telescope.
- The telescope probably comes with two eyepieces, which will have numbers on them. Counterintuitively, the higher number is the lower magnification (magnification is the focal length of your telescope, 700mm, divided by the focal length of the eyepiece). Start with the lower magnification while you are getting used to the telescope, as it will be easier to find objects and they will appear brighter. Avoid the temptation to go high power straight away. The barlow that increases by 3x, so would be rarely used. Maximum useful magnification is generally twice the aperture, so the max useful magnification for your scope is 152x. Most objects (galaxies, nebulae) look better under a lower power; high powers are most useful for the moon, planets and splitting double stars.
- Don't be disappointed with your first views. Beginners often complain that the stars don't look any bigger, so they think the telescope isn't working. The stars are so far away that they will only ever look like points of light. But with a telescope you will see more of them, and you will see their colours, double stars, etc. Star clusters are particularly beautiful.
- The moon is one of the best objects to start on. Avoid full moon as it just looks washed out and bland; look at the moon during one of its phases, particularly the terminator line between light and dark. On the terminator, mountains, valleys and craters will stand out in sharp relief as the sun casts shadows.
- Download a free app for your phone called Stellarium. It is a great resource for finding what is up there.
- And I'd recommend purchasing a book called 'Turn left at Orion'; it is the beginners' bible.
