Close Doubles in Gemini

[michaelmorris]

With a clear night with very good seeing, I decided to spend an hour or so sketching some close doubles in Gemini, using Sissy Haas's  'Double Stars for small telescopes' and the new edition of the 'Cambridge Double Star Atlas' as my guides.

All my target stars split with my University Optics 7mm HD  eyepiece on my Celestron C9.25.

• Eta Geminorum

Do you have a picture of your sketches?

I use the word 'sketch' in it's loosest meaning. I.e. "to scrawl, to make a series of marks"
