I have set up my Meade GPS 10" SCT on an ultrawedge and piggy backed my Skywatcher 100ED. I have a Meade Deep Sky Imager lll Color camera, a modded Canon 20D, a Phillips ToUcam and Starshoot autoguider. I have a dedicated Dell Laptop running XP with duo core processor.
I think I have got my polar alignment process down pat but I think the SCT needs collimating and I have a set of Bobs Knobs ready to install when I get some nerve.

So I think I,m ready to start having a go...especially with Orion coming into view.

Could someone give me advice about which filters I should purchase as to enable my best shots of nebulae, star clusters and maybe even comets....one day?
I also have a straight Nikon D80.
All this gear is sitting in a sirius 3.5 observatory in our orchard ( I chopped down the cherry tree!!!)

Many thanks for any and al advice
