Description

The five bright stars at the lower part of this nice asterism near NGC2683 bear some resemblance to the Cassiopeia constellation.

Revision B has been annotated using SIMBAD and revision C using HyperLEDA.

There are 19 quasars in this area of sky (see revision B) including some with redshift z=3. According to this Cosmology calculator the light travelled 11 billions light years from them.

I was testing the telescope after some changes and this asterism was a perfect test object.

Thanks for looking,

Vitali
