North America Nebula

The North American Nebula beside the 1st magnitude star Deneb in Cygnus is similar in shape to North America, and can be seen with binoculars if the sky is clean. The number of skies under such conditions has decreased in Japan.

Seyfert’s Sextet

NGC6027 2021-05-03 Seyfert’s Sextet is a group of galaxies located about 190 million light-years away from Earth in the direction of Serpens. Seeing is poor and the small parts are out of focus. Brightness is 14-16 mag, a dark object. I want good seeing and a longer FL (3m)!
