Object(s): NGC 3521
Category: External galaxy.
Class:
Constellation: Leo
Data: mag 8.9 size 7' x 4'
Position: RA : DEC :
Description:
Easily found at 22x. Look like a cascade at 44x starting with a mag 6.0
yellowish star SAO 118634 continuing to star SAO 118640, on to GSC 4921:1052,
on to GSC 4921:290, onto NGC 3521, and ending with a mag 7.9 star SAO 118661.
Bright, gray with stellar core, definite cigar shape. Core still stellar at
73x with gradual brightening toward the center. The galaxy appears to be at a
45 degree angle with an imaginary line formed by star GSC 4921:290 and SAO
118661, angle toward the GSC star. Beautiful at 110x, best view. Core started
to lose its stellar look, relatively bright and fairly large. Non-stellar
central core is slightly diffused at 146x, overall dimmer than at 110x. The
bright, glaring star SAO 118661 had to be moved out of the FOV.
Henceforth, I christened this galaxy and the stars, the “Bee Cascade” ;-). The
galaxy looked about 2/3 as bright as this very nice sketch I found on the
web.http://www.jwebdale.btinternet.co.uk/ngc3521.htm
