Hahahhaha excellent post Golgo.
Compared to monster reflectors, even the most lovely 6 inch refractor is but a toy. A nice toy for sure but still a pea stick compared to those scary monster reflectors.

I wonder what he does when his Dob is pointed almost straight up?

"I liken it to if you order unsweet tea and they bring you sweet tea and you take a big drink and it takes a few seconds to sink in you are not drinking what you thought."

That's just the taste of "aperture is king" flavored kool-aid.

I wandered over there once, but they weren't talking about telescopes, just some sort of arachnid.

I just goto the Reflector section to see what NGC891 looks like from a light polluted backyard.

You didn't also go into the CATs and Cass. did ya?
At least with Newts you can get great optics, SCT's now that's wishful thinking!

Actually the two boards are very similar. Both groups spend an enormous amount of time turning knobs. With us, they're called "focusing knobs." With them, they're called "collimation screws."

That was true with my C8. It always seemed to drift around and it took forever to get it just right, because the design is so sensitive. My 12" dob? It takes three minutes, tops, and is very easy. The rest of the evening, the only knob touched is the one on the focuser!

But it is true that one of the strengths of the refractor is that it stays in collimation. Usually, at least.

Not if I can help it!! Us refractor owners are more "sharp focused" when it comes to that. Mike

The reason refractors stay in collimation is that they have to, otherwise they would be unusable. Newtonians have very lax collimation tolerances because there is only one curved surface so they can be collimated by the owner in the field in a moment are two. Refractors are touchier is this regard. Some apo's require centering of the elements to within a few microns. No one sends a Newtonian to the factory to be collimated, it happens with refractors all the time...

I wander around CN because of my various scopes, but I consider this forum as home, followed by EPs.

Yes, but you can easily collimate a Dob. Collimating a refractor...good luck with that; maybe if you start now, you'll be ready by tonight....
that being said; I'm going to S&S Optica soon to purchase my Xmas Present, and Omni 102XLT; luckily it'll come collimated. Not that I wouldn't do it myself, its all part of the learning process and responsibility that comes with a scope. Just like I've never used an EQ mount; but I'll learn,of that I have no doubt. I love my 10XTi, at a dark site, I'm a happy camper. Here in town though (white zone, my front yard is boardered by skyscrapers (Denver Tech Center). I mostly want the refractor for planetary and lunar. I don't think of a reflector as any better or worse then a refractor; they're actually very complementory to each other. I propably will end up using the refractor more, just because its an hours drive to a dark site. I have no doubt I'll love both of them.
