ASTRO: Another M16/Eagle

There were several fine versions of M16 in this forum recently, so I felt
like reshooting it on August 25. I can't get objects that low during
culmination as the southern horizon is blocked by buildings and a tree, so I
could only start the exposure series after M16 was at it's highest point. At
the start of the series it was 18 degrees above horizon, at the end only 12
degrees. I was lucky to try this object on one of those rare nights where
the seeing was OK near the horizon.

Taken from the middle of Berlin with an 8" SCT at f/6.5, G11 mount, SXV-H9
camera, 14x5 minutes,Astronomik 13nm Halpha filter.

Looking good!

It's hard enough from my latitude and I'm well south of you. I had good
seeing last night but extinction low was severe, over 4 magnitudes. So
I started something higher but then the clouds rolled in and it was all
wasted effort. My problem on the low meridian is a tree I call the
Meridian Tree. A huge red pine that block an hour on the east side and
two on the west side at this declination. Shooting through it caused
those odd star shapes in my M104 shot so won't try that again. Still
waiting for that good night.
