The plan is to ramp up on double star observing and research this year. A long time ago I had borrowed Denis's first edition; recently, I ordered the second edition of Observing and Measuring Visual Double Stars for myself.
The book from Springer arrived today. Cool. A new chapter by Mr Perez talking about sketching. Lots of updates throughout. I didn't recall colour printing in the first edition. I'm really looking forward to this!
