Observing and sketching double stars

On the nights of December 8 and 9 for the first time ever
I observed and sketched double stars for a few hours on
two consecutive nights, and it was fun! Not only to make
the sketches but also to try and recognize the different
colours and try to estimate the difference in magnitudes
between the different components of double/multiple stars.

To read the full observing report and have a look at the
sketches of Omega Aurigae, Rigel, Castor, 14 Aurigae,
Struve 698, Sigma Orion and others just follow this link:
