|NGC 90 & NGC 93: Galaxy Pair (Andromeda) RA: 00h 22.0m / DEC: +22° 24'.0|
Instrument: 18-inch Obsession
The southwest corner of Andromeda is home to a fine galaxy cluster. Two of the brighter members are presented in the sketch at left. NGC 93 is centered in this rendering, which captures the view at 199X in the 18-inch Obsession. The 13.3 magnitude spiral features a stellar core embedded within a nebulous oval some 1'.5x1' in area. It is aligned roughly north-south with a trio of 13th and 14th magnitude stars immediately to the east. About 3' to the west-southwest, NGC 90 pierces the night. Its 1'x0'.3 form is elongated north-south. This spiral galaxy has a visual magnitude of 13.7 and paltry surface brightness of 22.8 magnitude per square arcsecond. An 11th magnitude GSC star shines one arcminute due south. A star of similar brightness stands sentry at the eastern field boundary. Another eleven sparklers provide context. While in the area, don't miss out on NGC 83 and several other galaxies lieing just beyond the field of view to the west.
