[APML] New Ha Image of ngc6888

["Brian Lula" <brianl@polytecpi.com>]

Hi All,

Just started working with Ha filters. Here's a 120 minute Ha exposure of NGC6888 using my 20" 
F/5 astrograph and IMG6303E in 2x2 bin mode. I took this a month ago in one of the rare nights 
we could do any decent imaging this hot summer. The image suffers from astigmatism and 
focus change by the night long cool down. This can see this in the close up of the stars...but the 
area is interesting with faint nebulosity visible surrounding NGC6888. 

20 exposures of 6 minutes each were used taken in mag 5.0 skies.

The image is at:

Best regards, Brian
