Sentinel Star Gaze 99 - Big Success
Well, after a couple of years having to deal with poor weather
for the Sentinel Star Gaze, this year decided to really show off.
A.J. Crayon and I made it out of Phoenix about 2:00 PM on
Friday, April 16. This day also turns out to be my 50th birthday,
a fact which has yet to sink in completely. I am, after all,
only 23 years old in my head.
We made it to the tiny Arizona town of Sentinel and a short
trip over the railroad tracks and down a dirt road to a big
flat spot in the desert. Several other astronomers are showing
up at about the same time and by the time it gets dark we
have 8 scopes and fewer and fewer clouds...
Once it is good and dark, I can see that the seeing is even
pretty good to a dark southern horizon, so I decide to chase
some objects in the far south. First is NGC 2440, a planetary
nebula in Puppis. It is obviously a planetary, even at 100X,
and it is in the field of view of a nice orange star and
delicate triple. Going to 330X it is pretty bright, pretty
small, somewhat brighter in the middle and elongated 1.8x1 in
PA 60. Averted vision does two things for this fine planetary,
first it doubles the size and also brings out a dark marking
across the middle of the nebulosity... [More to come!]
