One of my favorite double clusters and unlikely duo, but be that as it may, I chose to draw them separately. These two clusters are within the same low power, wide fov when viewed with most scopes, though at opposite sides. Centering each when viewing and drawing allowed me to better emphasize the impact of their particular nature.6755 is a total mish-mash of different magnitudes with little apparent rhyme or reason while 6756 is much smaller, and more definitive, with a tight core group and very faint background members. Together, they are an interesting pair that many observers overlook.

Michael,

 

These are excellent sketches of open clusters I have never observed.

Thanks, I have targets to look at in Aquila thanks to you.

 

Frank :)

Michael,

 

Wow! Concentrating on each cluster individually really pays off in your sketches. I have observed both but didnt resolve as many stars in 6756. Need to return and see what I missed! I really like how your sketches fade out at the edges.

 

Cindy

Cindy,

 I had upped the mags to see those stars in 56.I typically view in the 70-200x range but label a drawing with what power I thought presented the most attractive fov.In the past few years I have always gone through a sequence,70x,88,116x,140x and 200x,with the 11.Earlier years and drawings were almost always limited to 70x as I was more interested in bulk than small details.

Amazing variation in the star brightness.  And mega detail, wow!  I always struggle with sketching open clusters due to their complexity and vast number of stars, but you have done it so very well.  Looks exactly like what I would imagine looking through the eyepiece, which is why I love sketches so much.  Well done!
