Personal "rating" (at this aperture):  A
This is fabulous at this aperture! M37 is a large, extremely dense
open cluster of dim stars, with a red, dim central star. At 90mm, the 
red color is barely noticeable on the central star, and some of the 
dimmer stars are not apparent as in larger scopes. However, the
impression is almost exactly the same. That is.. a perfectly circular
dense cluster swimming in fairly dim stars, but of equal magnitude!
