[AZ-Observing] Horsehead Nebula and IC 2003

Managed to catch some photons from Anderson Mesa (Friday) and Beaver Creek  
(Saturday), this weekend. Both nights, I observed the Horsehead Nebula with my  
18-inch Obsession. Although obvious without filtration, the best views were 
with  an H-beta in place. David Sanders was at Anderson Mesa on Friday and we 
enjoyed  an unfiltered view of the Horsehead in his 8-inch, f/8 Discovery 
Dobsonian. I  suspect a 4-inch may have been up to the task that night. Jeremy 
Perez was at  Beaver Creek on Saturday and the Horsehead was visible in his 
6-inch 
equatorial  Newtonian. Though detectable without filtration--the back of the 
neck stood out  against IC 434--the best view through the 6-inch was with the 
aid of an  UltraBlock filter.
 
Here's a link to Friday night's observation of B33 (Horsehead) in  the 
18-inch: _http://members.aol.com/billferris/horsehead.html_

The drawing at the top of that page was made 10 years ago with my 10-inch  
Meade Starfinder equatorial Newtonian. The sketch and notes from Friday's  
encounter are below.
 
We were buffeted by gusts at Beaver Creek. This was an unsuspected surprise  
as conditions were calm in Flag and the forecast was for wind speeds in the 3 
to  6 mph range. I suspect the gusts we encountered may have been cool air  
draining off the Mogollon Rim. Despite the wind, I did manage one sketch. The  
target was IC 2003, a tiny planetary nebula in Perseus:
