8th August

Barnard's Star
I image this each year to follow it's rapid proper motion.
This compares August 2015 with July 2014:



The coordinates in 2015 were RA 17 57 47.67 DEC 4 44 17.1
and in 2014 they were RA 17 57 47.68 DEC 4 44 5.9
This is a shift of 11.2 arc seconds in 395 days which gives the proper motion as 10.35 arc sec per year
(The value calculated from 2013 to 2014 was 10.39 arc sec per year)

ngc6946 is a nice little spiral galaxy in Cepheus.
It is known as the Fireworks Galaxy
This is 6 x 10 minutes luminance
