Summary[edit]
| Description |
English: Comet C/2022 E3 (ZTF)
C/2022 E3 (ZTF) is a long-period comet from the Oort cloud. It reached perihelion (1.11 AU from the Sun) on 01/12 for the first time in 50,000 years. It passed 0.28 AU from Earth on 02/01. Since its orbit has changed, the comet will either return in many millions of years or be ejected into interstellar space. The green glow in the coma is the emission of diatomic carbon. This was my 3rd and final attempt at this beautiful comet. The background stars and galaxies are more interesting here than in the previous image, although the comet looked better when it was brighter (see here: flic.kr/p/2ofjJqt). All of the galaxies visible here are over 200 million light-years away. Some of the brightest ones are PGC 15975, PGC 15924, PGC 15866, and PGC 213292. See annotated version here: flic.kr/p/2oxGhQy Apparent magnitude: 6.7 Distance from Earth: 0.50 AU Orbital period: 50,000 years (before) / unknown (after) Velocity (relative to Sun): 23.6 mile/s (38.0 km/s) Total integration: 2 hours 31 minutes 151 x 60 seconds ISO1250 02/14/23 00:59 to 04:52 UTC Camera: Canon 7D Mark II Telescope: Explore Scientific ED80 f/6.0 Apochromatic Refractor (with ES field flattener) Mount: Orion Sirius EQ-G Guide scope: Svbony 50mm f/4.0 Guide Scope Guide camera: ZWO ASI224MC Capture software: N.I.N.A., ASTAP, PHD2 Bortle Class 6 ~19.32 mag/arcsec^2 (Summerville/Ladson, SC) Processed with PixInsight and Paint.NET |
