With the demise of 2017 S3 PANSTARRS the only reasonably bright comet in northern skies is 21P/Giacobini-Zinner. I was out with the telescope a couple of nights ago and spotted the comet without a problem at the eyepiece of the 10 inch Dob. I had the camera snapping away on the 8 inch Meade. This was the result:
The comet is around 8th magnitude right now it may brighten by another magnitude as it approaches perihelion in September. That makes it a binocular target if you know where to look.
Here is a finder chart for 21P for the next month:
This comet could not be better placed for UK astronomers! And look at the track it’s taking across the sky – the comet is following the Milky Way from Cassiopeia to Gemini! The Milky Way is dotted with open clusters and that will make some very photogenic encounters with the comet during early September.
