Very bright, pretty large, elongated 2 X 1 in
PA 0, much brighter in the middle at 100X. M-33 is naked eye on the
best of nights and obvious in the 10 X 50 binoculars. At 165X in the
13" there are several HII regions with dot the curving arms,
including NGC 604 to the north of the nucleus. On a night I rated
8/10 at 5000 ft. elevation this beautiful spiral really showed off
at 135X, the backround glow of M-33 sparkles with mottling and the
gorgious arms winding about the compact core make an "S"
shape that is ummistakeable. |
