Please don't put John in the same class as me (and I mean this most
respectfully) you are really lowering his stature.
I am a cheapskate bodge type boffin who is plagued with horrible
weather, John is an excellent astrophotographer with equipment I would
sell my third child (we are stopping at two) to own who is plagued with
auroral glow for two years out of every eleven.
