10.1'' reflector  115 x
 
Bluish colour about 14' across. Fairly loose collection of stars except near the center where it's concentrated. The core itself is about 4' across. Anywhere from 100-200 stars are resolvable. It makes an incredible impression when it first appears in the field, looking like a thousand points of light.
