Is there a general rule of thumb when considering eyepiece size selection? Going beyond low-medium-high.. It is wise (for example ) to not quite double your magnification between each eyepiece? 20mm/10mm being the Skywatcher supplied kit seeming to suggest this - although it does seem (observationally) a large jump from 60x to 120x..

Using my 8" dob scope, and playing around in Stellarium with top shelf eyepieces…
Would (again for example) a 24 (50x), 13 (92x), 7 (171x), 5 (240x) seem like a good combination? - which the Stellarium simulation seems to suggest it is.

I'm also assuming that practically 240x is going to be about the maximum usable accounting for tracking if nothing else.

Looking forward to your views..

Thanks.
Darren.
