Hello All,

A few images acquired in May, June and early July. Usual tandem setup.  All in nautical twilight which seems to support the OSC camera and Ha for luminance if the exposures are kept short for colour.

Lovely images Roberto.  Such dedication. 
I always thought that Sh2-86 was NGC6820

Thank you Carole!  NGC6820 is indeed within Sh2-86; it's the small reflection nebula (looks yellowish) towards the bottom right.  The Astrobin link shows its location if you hover over the image.
