May's Double Star of the Month (AN) - 39 Bootis

[chiltonstar]

Three double stars in one issue, with 39 Bootis as the main pair. The separation of the pair is currently an easy 2.6 arcsec.

Using my 180 Mak (insulated) with a 10mm Baader Ortho EP giving x270, the view was very similar to the simulation below using Aberrator. To me, the colours were close to silvery white, certainly no obvious colouration. Anyone else see colours in this pair?

Other doubles mentioned in the same issue are Xi Bootis (which I had a look at at the same time as 39 Boo), which is a well-separated pair with a strong colour contrast - yellow-white and purpley-brown to me. Also mentioned is the nearby glorious Izar - always stunning with its strong orange-blue colouration. An image taken with my scope attached as well.
