I would imagine that for M20 would need to wait until 4-5am at the moment to see much. In my 12" at 113x I can see the dark lanes with averted vision. Needs a really dark sky to get them with direct vision.
At lower power, say 67x that I used to have with the 24mm Pan, they were really more of a hint of dark lanes.
Looking forward to trying the new Ethos on it!
