Post November 1, 2004 Loop Asterism Near Beta Ursae Majoris- Mitch Luman I've just rejoined the group after a few years' hiatus. My observing did not falter,...
I think I can partly answer my posed question myself (after a discussion with Bill Gray). Horizons have considered the moon as a perfectly smooth globe. The...
Mitch, The asterism is known. I even wrote about it in my April 2000 Small Scope Sampler, but at the time, I had an editor with a tendency to cut stuff, and ...

Friends, This comes from a member of the Board of Directors of the San Diego Astronomy Association. I felt it was a query that deserved a high- power...
Baade's Window is a region of low obscuration in which we can see nearly out to the center of our galaxy. The actual center of the galaxy is several degrees...
I'm pretty sure the CO2 absorption in the visible range is neglgible, but they are substantial in the IR---the 'greenhouse effect' comes from the CO2 (and...

Tom This may not answer the question but this is what I can gather... It appears there are 3 "Baade absorption holes" in Sgr. If I'm recalling correctly, there...
Coming in a bit late on this: I think this is the asterism that Barlow Pepin pestered me about a long time ago (circa 1990?), and I think this ended up being...

Harold Corwin has pointed out that I misidentified the moderately faint planetary NGC 6439 with a brighter nearby star about 1' north. This has percolated into...

As most of you know, in the morning Venus and Jupiter will be quite close. What you may not know is though this might otherwise be a ho-hum visual event,...
... Brian, I actually noticed that "error" when the Kerber et al. positions were fed in to the SkyGX lists, and that one popped out as a large-ish delta. I...
