DELTA LYRAE A nice pair of stars more easily separated with the naked eye than the Epsilon pair. the stars of Delta are 12 minutes of arc apart ( which is about 1/3 the diameter of the Moon's disc). Delta 1, at magnitude 5.5,
is bluish in colour, while its component, Delta 2, is slightly brighter at visual magnitude 4.5, and has a reddish tint. So, here we have a pair with contasting colours. Although, with the naked eye, the colour contast cannot be detected due to the faintness
of the components: With binoculars or small telecope the contast is beautiful to see. There are many faint stars in the field hereabouts, which may possibly constitute an open cluster of stars.
ZETA LYRAE. This is another lovely contrasting pair,
but much closer than Delta. (44 arc seconds). You need a telescope to see the colour contrast clearly. Zeta A, the brighter component is reddish, of magnitude 4. The fainter component, Zeta B, is bluish -green and of magnitude 5.5. binoculars will split
the two stars, but a telescope is necessary to bring out the lovely colour contrast.
