About this image

Got out of bed in the middle of the night to attempt imaging some of the low altitude summer objects with the Seestar which had to be mounted on an extra tall tripod to see over the hedge. In truth the transparency was not great but the little scope did quite well.

M20, the Trifid Nebula is obvious at right with the open cluster M21 at top left. Altitude c14.5 degrees.
