    Lovely one! As is taken with a reflex and at F12 the result is more than excellent.

    Thank you!  I'm slowly discovering that putting a lot of time into clusters can be just as rewarding as a lot of time into nebulae and galaxies.  I should go back out and add some more data to this one.  Thank you for your inspiring image!
