μ (Mu) Cephei - The Garnet Star in the Constellation Cepheus 2020-07-11

Aberkenfig, South Wales

Lat +51.542 Long -3.593

 

Skywatcher 254mm Newtonian Reflector, Olympus E410 at prime focus. EQ6 Syntrek Mount.

 

7 @ 40s ISO 800

10 @ 50s ISO 800

6 @ 60s ISO 800

Also 10 dark frames.

 

Processed with Deep Sky Stacker and final levels adjusted with G.I.M.P.

 

The final image is cropped but it still displays some slight coma towards the edges. This is one drawback of a parabolic f/4.8 Newtonian.

 

I decided to revisit this unmistakable star and capture some frames with longer exposures. A better result than my last effort in July 2019.
