Castor A & B sketch and phone image

[IB20]

One of my favourite doubles to look at through a refractor, it’s extremely pleasing to observe as the stars usually give perfect airy discs. Very similar colouration, magnitudes and size with a fairly generation separation.

Castor is always a favourite. Despite being plain white it still draws attention.

Very nice sketch 🙂.  Nowhere to hide with only two stars to sketch.  I'm going to have to get a look myself.

Just came in from a run under the stars, Alpha Gem was my last observation. 

Had a go at Kappa Gem as well, but not entirely sure I had a clean split or not. Will leave it out of the log book for now.

Very nice sketch, good job!
