NGC 3090

Observation Notes:

After hunting for a variety of challenging objects in the constellation Sextans and coming up empty-handed on several counts, I finally settled upon this diminutive puff. NGC 3090 showed up about 30 arcseconds from a prominent star. This galaxy resides in the midst of a cluster of fainter galaxies. I was not able to see any of these other companions with my 6 inch (15 cm) scope, but a check of the satellite loop when I got home revealed a stream of thin cirrus breezing overhead during the observation. On another, clearer occasion, I'd like to re-address this group and see if any other members are discernible. Have a look at these sketches of the group by Bill Ferris with his 18" Obsession and Eric Graff with his 6" f/6 Newtonian. Thanks Eric for suggesting the challenging targets in this section of sky.
