Hi Paul- everyone will have their preference visual vs eaa vs ap. For me personally, if I’m out somewhere really dark I just love looking through the eyepiece (visual). But the problem is that I find this is less satisfying in the city light-dome (especially for deep sky targets) so tend towards eaa and ap.
Regarding eaa vs ap, eaa is much quicker, easier for beginners but won’t yield the same quality results you see on some of the pics posted on these forums but can still get quite decent results even in severe light polluted skies. Having said this I think you would want at least a few looks through an eyepiece at some stage when you start!

Some equipment to consider for eaa:

Scope:
Any scope will work but 6-8” is a great middle ground price vs performance.
Alt-az mount will work for exposures up to about 30sec. EQ mounts are necessary for longer exposures and open up more possibilities down the track for dimmer targets or ap but more setup time required. GOTO and tracking mounts are a huge advantage.

Computer with livestacking software:
Laptop or mini pc using sharp cap or similar software (cheaper if you already have a pc and more features/flexibility but bigger learning curve and longer setup) but better for ap down the track.
ASIAIR pro for livestacking (very easy for beginners to get good results but need to buy all zwo products and stick with their setup / config)

Camera:
A high sensitivity ccd or cmos is best. Cooling is not nnecessary for shorter exposures but good for ap down the track. One Shot Colour camera better for eaa.

Filters and Reducers:
Depends on target, sky conditions and scope setup. A big advantage is with focal ratios of around f4-7 so can use reducers too achieve this. The faster the scope the quicker the result! A light pollution filter great for nebulas from the suburbs.

Hope some of this helps!
Dave
