Hi,
I'm a complete beginner when it comes to astrophotography and I'm after some advice regarding suitable webcams for astrophotography of Nebula. In particular I'd like to get some reasonable images of the Orion Nebula since with my telescope (NexStar 130 SLT) I can usually see it very well. But I need to do it on a budget of around $100. Also since the 130 SLT is an alt-azimuth mount does this limit the length of exposures I can take or will software such as Registax eliminate any image rotation?

Thanks,

Cheers
Larry
