And I'll see where it goes from there and decide later if I wanna get into a full AP setup.
Does anyone have any sample photos of what can be achieved on that type of setup?
Also, weather these days is actually quite sucky, haha, when are the best months for Astronomy for us downunder?

An 8" f6 standard Dob is effectively a 1200mm telephoto mirror lens. At this focal length even a 1/4 second exposure will produce a blurry Moon (although typically Moon shots are faster shutter speed. Add a Barlow for extra focal length required for planets and whether still photography or video you will find the image moving too fast.
In 30 seconds your field has significantly shifted so I'm not sure how you can photograph without any form of tracking. Alt-Az motorised tracking is OK but you get field rotation over time. You really need EQ tracking.
