My last question on the Astronomy Forum was answered perfectly. Let's try another one. I just bought a (s/h) Sky Watcher 200mm dobsonian and have already been stunned by seeing Jupiter with its coloured bands and its moons in brief holes in the danged cloud. But it is not easy to point it...

When I read any physics articles online I always end up receiving the wrong message. especially in terms such as 'observe'. what does this term mean when its used to describe exeperiments such as the double slit

Is it possible to rig a Truss Dobsonian telescope like this one so that you can control it remotely from inside of a building while the telescope itself is on the roof of the building? Then is it possible to attach some sort of adapter to the telescope that would allow you to hook up a camera...

I am going to make a Dobsonian telescope. Primarily a 6" f/8. I have no idea what the secondary mirror size would be an its distance from the centre of the primary. I have been told that if the secondary is too small then the effective aperture would be reduced. And i do not understancd these...

I just recently got a dobsonian reflector telescope, (Orion SkyQuest XT8 PLUS Dobsonian Reflector Telescope) and I was wondering what the best way to see the andromeda galaxy would be using the telescope? Of these, which would be the best eye piece for that sort of thing?: Orion 2" 28mm...

My father will be lending me his dobsonian telescope, but I live in the city. Is there much to see through all this light pollution?

Sorry to barge in on a thread, and I am sorry if this is the wrong place, but is this a recommended scope http://firstlightoptics.com/proddetail.php?prod=dobsky150 for a amatuer and what could you expect to see with almost/ none light poplution.

huge difference between a 6" dobsonian and a 10"? Would one notice a huge difference between a 6" dobsonian and a 10"? I've used a 6" and liked it and have about 500 for a new 'scope. The 10" from Orion is about that much. But of course if there isn't a massive difference, I could get a smaller...

Well, I have a Zhumell Z8 Dobsonian. 8 inch reflector. It's kind of heavy, but is easy enough to transport. It didn't cost me much, under 400 I think. I am a big fan of it. I personally wouldn't ever choose portability over viewing quality, as long as I can move the thing. I'd always feel like...

I got a Zhumell Z8 Dobsonian. The stock lens is decent, I think. One is a 68 degree Plossl and the other is a zoomed in Plossl that I don't know as much about. I want a new lens so I can get better views. I am mostly interested in deep sky objects, seeing as there are only a handful of...

can i use a watch glass as a primary mirror of dobsonian telescope?

how can i get the magnification of dobsonian telescope i made??

can i use a concave aluminum mirror as an objective mirror of a dobsonian telescope??

Orion's XT8 8" Dobsonian as a good beginner scope hey all... question! i posted this thread a while back and got some mixed reviews on what i should get as far as a telescope... well I really would like to get one before Mars gets nice and close this summer.. i figure that will give me a...
