|Jones-Emberson 1: Planetary Nebula (Lynx) RA: 07h 57.9m / DEC: +53° 25'.3|
Instrument: 10-inch Starfinder
This large, faint planetary nebula is a challenging target for moderate aperture. It's as much a test of your observing site as it is of your observing skills. Don't expect to see Jones-Emberson 1 under light-polluted skies with any aperture. But under the dark, transparent skies of northern Arizona, this gossamer cloud is visible in my 10-inch Newtonian. The sketch at left presents the view at 63X. The spot is marked by a four-star asterism, which looks something like a backwards rendition of Corvus, the crow. This grouping stands just inside the east boundary of the field. Close inspection reveals the northwest corner star of the grouping to be a triple. The star at the southwest corner is 9.1 magnitude HD 65120.
