Awesome, what a globular should look like in a 4-inch, very dense!  Not very 
bright at 33x, dimmer than most OC and look more like picture of globular.  
Best at 50x, many stars seen, orange star in middle.  Still good at 125x, many 
stars and orange center star still seen.

(This was one of the few observations I made of my old achromat).
