open clusters IC 4756 and NGC6633

[mark81]

I've been meaning to check these two clusters (in Serpens - just outside Aquila) out for a while and I did last night with the ST80.  Not the most amazing clusters upon first glance but when you spend a little time at the eyepiece you'll agree they really are worth a look.  IC 4756 starts with this chain of, I guess mag 6 stars which create a little boundry and then within this boundry sits the cluster itself which are hundreds of very faint stars all packed together - dark skies I imagine will really help to begin to resolve them.... THEN if that isn't enough, if you nudge a couple of degrees over - (going away from Aquila) you'll see NGC 6633 which is much smaller but very similar in the way its made up of many faint tightly packed stars.   Well worth checking out if your in that area tonight....

Found it when flicking through the Cambridge urge photographic atlas... the IC number probably makes it less visited than it should be as it’s not exactly hard to see.
