Thumbs up What can I expect to see?

Hi again, Thanks for the advice I recieved on my thread that i posted a few months ago. With that advice on board "santa" bought me a 20mm Super plossl eye piece and a 2x Barlow for my scope. It was quite a remarkable change in quality of what i was viewing. But this time my question is - My scope has a 70mm aperture and a 900mm focal length. What sort of deep space objects am I likely to bo able to observe - realistically? (It is refractor type scope.) I have been doing alot of reading and studying my astronomy book learning how to use the RA and Dec settings properly so any info would be great as i am keen to have a really good look at what is out there. Also the charts in The Astronomy Australia 2011 book I have tabulate the RA of objects and under it in brackets is some sort or time zone I think.(in the column heading) Can anyone offer an explination for me as to what this means if anyone has that book, I figure my not understanding it properly is due to my level of novice but as i said i am very keen to learn how to do this properly!

Thanks
