Hi Malcolm - I knew you'd ask me a hard question!!
D=130mm
F=900mm
is what it says on the side of my scope. Is that what you mean?
I was able to get quite a bit of detail (craters) with the wide angle but no I dont think we tried the 10mm. Maybe thats one for tonight!
I did set the scope on a star cluster last night in the north - I apologise constellations are not my strength so I have no clue what I was looking at. I could see stars and had it focused (to my dodgy eyesight) but I dont really know if what I was seeing was impressive or not.
In this house it is the blind leading the blind!
For me, my main objective is to see as much of the moon as close up as I can.
