Hey psalm. I regularly watch the moon transits on Jupiter with my 6inch dob. I watched Ganymede 2 or 3 nights ago and I have seen io transit several times. You will not need dark skies as I observe this with my backyard light pollution and you do not need super expensive eps as I am using the ones that came with the scope. You will only see the shadow which will be a small black dot. I have never seen the moons you will need a bigger scope for this I suspect. Get the "jupiters moons" ap. it will tell you exactly when the transits happen . And it's FREE
. It's an awesome sight. Every time I've tried to observe this i have succeeded so you will have great views with an 8". Good luck
