This image is a proof-of-concept shot.

It shows that binocular comets can successfully be imaged with very basic equipment, i.e. a DSLR with a 50mm lens and no tracking.

The object shown is Comet C/2015 V2 (Johnson), shot on June 19, 2017 at 22:30 UT from La Palma island. At this date the comet had a visual magnitude of about 8mag and was visible in 10x50 binculars as a faint and featureless smudge.

For image aquisition we used a Canon DSLR @ISO6400 and a 50mm lens @f/2.8. One hundred individual frames of 3.2 seconds were exposed using a remote release timer. During the shots, the camera rested on a tripod and was not tracked. The individual exposures were combined later with the freeware Deep Sky Stacker to produce the result. Some additional Photoshop enhancements were applied.

The image displayed here is a 50% crop of the result. It shows Johnsons false nucleus, a greenish coma with a diameter of 7 arminutes and a dust tail with a length of 15 arcminutes.
