comets are not my word, but everybody talks about Wirtanen. So I could not resist.

Imaged with the ASI094MC-Pro @ my Celestron RASA 11. 172 x 1 minute, so total exposure time was only about 3 hours.

Processing with PixInsight and Photoshop CS6.

There is an object in the background I do not know. Can you tell me what it is? I marked it in the second image with a green circle.
In the red circle you see the planetary nebula PN Ba 1
