Next steps for widefield and DSO

[PapaPlanets]

Hi,

So I have the bug and I need to work out what my next steps are for widefield and DSO.

I currently have a Celestron Celestron C6 XLT on a CG5-GT mount and Canon EOS 600D with the kit lens and a F1.8 50mm.

I seem to be at a little bit of a crossroads as where to go next so any help would be appreciated. Seems like birthdays, xmas and bonuses are covered for the next couple of years.

1. Light pollution. Mainly from an old orangey street light at the front of my house (once the neighbours security lights go out) I guess the Astronomik Clip Filter is the best option? Any other suggestions?

2. Attaching camera to mount. I'm clueless here, can I get something to directly attach the camera to the mount or do I need to / can I somehow piggyback it on the telescope?

3. Guiding

i) PHD? / Autoguiding? I'm a bit confused about the auto guiders and even how they work. A webcam and PHD seems like the value option to me? Can you utilise any of the new wifi GoTo adapters in this setup or if not, is it webcam -> PC -> GoTo and what are the recommendations for the PC -> GoTo cable?

ii) How do I attach two scopes to my mount?

iii) ST80 vs WO ZS70. Obviously the ST80 is a fifth of the price, but I think I would only use it as a guidescope where the ZS70 looks like it might be a great little scope for imaging too? Which leads me on to...

4. AstroTrac (Holiday special) I think the SZ70 would work well with it? I'd probably also want to get something like a EF 200mm F2.8 lens as well at some point?

thanks in advance for any help and apologies for questions you've answered before I'm sure. I've had a look through the forum and other places but couldn't seem to find the info I wanted.
