Comet 46P/Wirtanen &The Pleiades

Comet 46/Wirtanen is relatively small, approximately .75 miles in diameter. It has a short orbit period of 5.4 years and is considered to be in the Jupiter family of comets because it's orbit does not extend beyond the planet. It is also considered to be a "hyperactive" comet in that it contains more ice (and therefore emits more water) than expected. It appears bright in the sky because it is the closest it has been to the Earth in centuries (i.e., approximately 7.5 million miles).

 

Lens: 120/2.8 S-M-C Takumar
Camera: Modified Canon 650D; ISO 800; Raw capture
Exposures: 2 @ 90 sec.
Mount iOptron CEM60
Note: Images were focused using the camera's live view function. Subframes were aligned and combinded in Photoshop. Multiple frames were not possible due to the comet's relatively rapid motion across the sky. Also, the moon was past first quarter, prohibiting the use of long exposures.
Taken from my backyard observatory in southeastern Minnesota shortly after 7 PM CST on 12/15/18.
