No filter, 65 minutes, 06/29/2003

Processing:

D-19, 7.0 minutes @ 68F, 35mm negative scanned with Polaroid SprintScan 4000 (4000 dpi)

Scan is a crop from 35mm negative, scan processed in Photoshop CS5.1

Location:

near Mt Pinos, CA

Notes: This is one of the Messier objects not currently 'visible' from my Thousand Oaks observatory ... In an effort to 'fill in' my Messier images page, I will post what film images I have. My film scanner is not presently hooked up, so I am using scans made for my old film website from the early 2000's.

Most of the film scans from the 14.5" f5 Newtonian reflector were centered on the object of interest, and were generally scanned to file as a 2000 x 2000 pixel crop of the 35mm negative.

Reduced in Photoshop to 1600 pixels, and saved under "Save for Web & Devices".

From the NGC / IC Project:

Contemporary Visual Observation(s) for NGC 6637
NGC 6634 = M69 = N6637 = E457-SC14
18 31 23.2 -32 20 53

See observing notes for N6637 = M69.

Corwin equates Lacaille's N6634 with M69.  This implies a 1? error in the dec of 
N6634 too far S.  Listed as nonexistent in the RNGC but not equated with M69.

=================================================================
NGC 6637 = M69 = N6634 = E457-SC14
18 31 23.2 -32 20 53
V = 7.7;  Size 7.1

17.5" (7/29/92): M69 is bright, moderately large, 3' diameter, round, fairly 
symmetric appearance with a large core surrounded by a small halo.  A bright mag 
12.5 star is embedded in the core or contains a bright stellar nucleus.  Several 
easy mag 13.3-14.0 stars are resolved around the edges of the halo and 15-20 
very faint mag 14-15 stars are visible in the halo with averted vision.  
Additionally, a few stars are also detected over the core. This is a pretty 
globular with averted vision located 4.5' SE of mag 7.9 SAO 21059.

8": fairly bright, bright core, lively halo, few stars at edges, difficult to 
achieve resolution.
