61 Cygni Proper Motion 2013 to 2020
Aberkenfig, South Wales
Lat +51.542 Long -3.593
A sequence of images I have taken over a period of 7 years which display the proper motion of this well known binary star.
Images captured using a Skywatcher 254mm Newtonian with a Modified Philips SPC 900NC Webcam on LX Mode. The telescope was initially mounted on an EQ6 HD then an EQ6 Syntrek for the later captures.
Hot pixels removed before final levels slightly adjusted with G.I.M.P.
G.I.M.P. used to align & slightly crop images with layers tool. Annotations added also added with G.I.M.P.
Another page from my observations log.
Best viewed in intermediate expanded mode.
