+1 what Brent said.
You're going down the same path that I went down about a year ago.
If they're cheap accessories, and you cant try stuff out elsewhere, it's all valuable experience.
Have a read of this thread though

A red light torch is an essential too.
I found a good book a worthwhile investment. My local library had some good ones (no decent bookshops round here to check them out). Some apps are very good too. The Sky Safari range are on sale too through December. As Brent suggested, Stellarium is terrific, although I find it hard to use in the field.
Plan a list and get star hopping!
Cheers
