Neptune

Last night was unusually clear for the Summer season. This diminished the dreadful orange glow from sky pollution. I even got a rare glimpse of the Milky Way through Cygnus from my own rooftop observing site. I therefore resolved to get a view of Neptune. Finding it was not too hard starhopping from Deneb Algiedi and Nashira in Capricornus. It took some time to confirm I was observing the correct target comparing it to the star charts I had prepared.

The object itself is rather small, approximately 2.5". However, at a magnification of x240 the disk was easily observable and had the characteristic pale blue colour.

I rounded off the night observing the usual M22, M8, M11, M24, M17, etc.
