I have a couple of small Newtonian Reflector OTAs free to a good home. One is a Bushnell that I picked up at Value Village. Small diameter and a short tube....
Love the image. In the article, this sentence isn't quite up to par: "a new category for objects that circle the sun and are too small to be considered...
I thought the Astronomical Union met every three years, but the article says they're meeting after only two years. Is it also true that their new definition of...
Not quite the longest day of the year, but it might be the clearest day that was nearest to the longest day.... I was able to observe Saturn tonight (goto is...
Bah, humbug. Tell them you BUY things or approve purchases. If I remember correctly, this magazine has advertisements. Those advertisers pay the publishers...
Just read that our atmospheres lowest layer, the troposphere, has 3/4 of our atmospheric mass in it. That layer is quoted as being 17km thick at the equator,...

Katy, Both the Lagoon and Trifid Nebulae in Sagittarius are good show pieces. Near by, also in Sagittarius, is the globular cluster M22. O'Meara calls it the...
The visual view was considerably better on many nights (even later on in the apparition.) At the 8" disc diameter shown, I guess I can pick up on some 1 arcsec...
Hi all from Billings -- June 29th -- first light in my new 102mm Mak. I couldn't get out of town, so spent several hours looking at Jupiter from my friend's...
Hi Katy, I'm here in Phoenix...all I have with me is my 7x50 binocular. There is too much heat and pollution to make bringing my scope worthwhile. Have fun...
