Astrophotography with an Alt-Az Mount

Hi,

Wasn't sure where exactly to put this, as the Beginners astrophotography seems to be full of pictures, not questions.

Anyway..

My equipment build up so far is as follows:

CPC1100 - Alt - Az mount
F6.3 Focal reducer
Dual Band OIII/Hydrogen Alpha Filter (ASI), plus holder
ASI462MC Camera
Canon EOS400D camera, not currently IR modded, but planning to
Various adapters, to connect all of these together in a chain.

My questions are:

I understand I am limited by the Alt-Az mount, to 30-60 second exposures, is it ok to take lots of them and stack them? Will the results be significantly worse than using an equatorial mount?

I have heard that the Wedge that Celestron sells, is not quite stable enough for the CPC1100, is that true? If so, what are my alternatives?

Do I need a focuser replacement to work effectively with my imaging? If so, what are the options?

Given my current setup, what is the likelihood that I will produce acceptable images? The Alt-Az setup seems to be my biggest issue.

Thanks for any input.

Cheers
