Orion is not upside down for us, it's upside down for you!
Welcome to the site and forum, and thanks for the feedback. The aim of the site and forum is to hopefully spread some knowledge around, bring knowledgeable people to a central location where they can share ideas and views and hopefully bring beginners like yourself in.. hopefully popularising astronomy because we all know how great a hobby it is!
So spread the word, bring your friends back!
Regarding the Sony DSCP100, it is a great camera. it's getting quite cheap these days too, because the P150 (7mp) has just come out. If your budget can extend a little further, the Sony DSC-V1 is probably a better camera for astro-work with a few more manual features, but there's not a significant difference from the P100.
All of the photos in the images section of IceInSpace were taken with the P100, so it can do a fairly good job, but to get the most out of your shots you need to take multiple shots and stack them and do a fair amount of post-processing as well.
It just takes time and practise, and I learnt lots of tips and techniques from other forums around the place, and I'm happy to share whatever knowledge i've learnt.
Good luck and hope to see you back!
