4.5", 6", and 10" Newtonian astrographs.
2 ST80s; ED80; 3 CCD cameras; 5 EQ mounts: all polished, tuned, and modified.
The rule of telescope features: aperture; equatorial tracking; or low cost. Pick any two.
Quote:I found it interesting that most *very* large cities like London have an inner White core, that inner white core is *several* times larger in e.g. Chicago or Manhattan.
Quote:Toronto, Canada has a very large area of light grey compared to e.g. Manchester.
First and foremost observing love: naked eye.
Last but not least, telescopes.
And I sometimes dabble with cameras.
Quote:environmentalism isn't even on the radar here let alone light pollution.
Quote:The one lucky stroke I have is that our appartment complex has a huge wall built of some kind of thick plastic or something that is designed to block out the road noises (which it accomplishes quite well) I don't think it does anything for the sky mag, but it blocks out many of the immediate area street lights.
I'm almost certain I can't see mag 4 stars when the moon is out here. I'm now second guessing myself, but when there was no moon I believe I made out a mag 4 constellation, well anyway I haven't been able to see it at all since the moon is over the horizon now, not even a single star from it.
Quote:According to it, with a half moon I have mag 5 skies. Don't quite buy that. Here's the strange part is that I can just barely make out the head of Orion and yet the sword is clearly visible. I would say 4 makes more sense, the sky is more dark gray than black tonight.
Thanks for the link I downloaded it. Two questions if you don't mind...How do you set your local time and what do you do when your trial period runs out?
Edit After an additional observation with orion moving away from the moon a bit I wouldn't say the head is so hard to see, but the sword still looks somewhat brighter to me. I caught his bow this time, something I've never caught before what mag is that?
