Hi guys,
Its too late to worry too much about the scope, you have plenty of equipment to get into astronomy. From my three months of experience there are two ways to astronomize...
1. get a guide, learn constellations and try to locate things that interest you (planets nebulas clusters)
2. Look through your scope, twirl it around and look at stuff that interests you. Then you need to learn constellations, get a guide and try to work out what you just saw!!
Either way a skyguide is helpful, I found a star atlas was a bit too much detail for me, I found the free monthly guide at
www.skymaps.com simple enough for me (Obviously you will need the Northern version). Also as mentioned before sky and telescope magazine has a sky map in it as well as some interesting articles...Oh and it has lots of adverts of huge telescopes we can't afford!!
Have fun
Steve
