My favorite picture in that article is the owner looking at the Sun with a 42" full aperture Mylar filter. The guys got guts..imagine what would be left of your eye if the filter fell off .

"I've already observed planetary nebulae at 1600 power and the hand tracking was really no problem."
That seems amazing to me - handtracking at 1600x?
Any I like the way he packs his garden chair inside the rocker box! And a team of half a dozen to push the lot to the trailer!!

Yeh, and if you want to know the meaning of the word "dedication", forget the dictionary, just call the Doctor. Amazing!

I can just imagine the sales pitch......"It even comes with haemorrhoids..."
Just too dang big for my taste. Still, I'd be at the front of a queue at a star party.

I do not see a point in something this big AND portable...
He should have a permanent site for this monster (in which case it wouldn't be a monster any more, just a big reflector..)
