Notes: The center of this field is on the southeastern edge of the great Scutum Star Cloud, about 2.6 degrees SSE of M 11. The planetary nebula IC 1295 is apparently very blue, and not well rendered in this longer exposure ... even though the sky was 'cloud free' during this sequence, as it has been very hazy, with fog later in the night. See a 14.5" image of NGC 6712.

18" (8/23/03): at 435x, approximately three dozen stars can be counted, although 
the eastern edge of the halo resists resolution.  A dark lane cuts through the 
cluster on the south side running SW-NE and detaching a small piece of the halo 
on the SE side and flattening the central blaze which begins just north of the 
lane.  IC 1295 lies 24' ESE and both are nice framed within the field of the 20 
Nagler.

17.5" (6/29/00): at 220x this is a bright, moderately large cluster, ~6' 
diameter in a very rich milky way field.  Contains a relatively large, intense 
3' core with a number of very faint stars peppered over the background glow.  A 
small, partially resolved piece is detached at the SE end by a dark lane.  The 
surrounding halo includes a number of brighter stars, though it is difficult to 
untangle the maze of stars in the halo from the rich milky way background.  
Roughly 30 stars are resolved at 280x, although it is difficult to accurately 
count. The core has irregular appearance with a flattened side caused by a sharp 
light cut off on the south side. PN IC 1295 lies 24' ESE.

17.5" (7/1/89): about two dozen stars resolved over haze.  A very rich clump is 
visible at the W side and a detached clump is at the SE end.  The outline is 
irregular.

13": about 15 stars resolved including several extremely faint stars, very 
mottled, ragged edges, non-symmetric (flattened on the SE side).

8": grainy, very lively but only a few stars resolved at high power.
