Enjoyed some dark sky time with the 18-inch, last night from Anderson Mesa. I'll post more detailed notes with links to my drawings in a day or so. Among the...
Last night I spent a good part of an hour looking for the very difficult 16th magnitude planetary, Abell 5. It surrounds a 14th magnitude star that makes it...
I tried both last night, and many times before. They're both a "no show" for me and my little 'ole 25". I tried 200x and 300x, with and without OIII, but no...
... For what it is worth, it was a bit darker than usual last night according to CCD images and my SQM meter, which was reading about 21.5 over the hours...

Bill, Possible sighting for Abell 13 but a negative for Abell 14 from me. These were with my 63-cm scope under NELMZ 6.5 skies. My notes are: Abell 13 ... ...

NGC 6888 (The Crescent Nebula) and NGC 7635 (The Bubble Nebula) are both classified as emission nebula right? I see NGC 6888 referred to as a Wold-Rayet shell...
Maybe another useful way of thinking about the classifications is _age_. Neither object is a planetary nebula because they are young. NGC 6888, as you...

Hi Brian, Thanks, Jerry ... Photoshop for Astrophotographers http://www.astropix.com/PFA/PFA.HTM...
Just wanted to share some notes & sketches from observations made the night of Nov. 30-Dec. 1 and Dec. 3-4. This first posting includes notes and links to my...
Here's the second installment of my observing notes from the week just ended. The night of Dec. 3-4 was bitterly cold at Anderson Mesa. But before the wind and...
Hello all; I was at a dark site about 100 miles from Phoenix tonight and the gegenschein was quite prominent. I saw an oval of light, about 3degrees by 10...

Steve Thanks for sharing your counterglow observations. I recently read some of Barnard's notes concerning the gegenschein and was a bit surprised by his...
Hi Steve and Matthias, I've checked this PN in the Emission Line Survey of the Milkyway. It has a very similar appearance as HFG 2° further north: it is...
In re the visibility of the gegenschein under less-than-wonderful sky conditions: it is still visible from Mars Hill on good clear nights. Readings from the...

I'm a bit surprised by some of the recent posts regarding the visibility of the Gegenschien, particularly in regard to the naked eye limiting magnitudes being...
John, ... Interesting. I describe my rural NSW observing site (1000 metres elevation) as NELM 6.5, on the basis that I've never done better than NELM 6.6...
I agree with John's assessments regarding various NELM's and the ease of visibility of the gegenschein. I also feel that the limiting magnitudes folks report...
The Gegenschein is never exactly obvious from my local dark sky site (ZLM 6.4 to 6.8 typically), but if it is clear of the Milky Way and fairly high, I can...
