The 'A' star was 1/2 way
between baby blue and robins' egg blue, and the 'B'

The primary is a brilliant red while the secondary is a soft blue, (but larger). It felt like the primary was in sharp focus and the secondary was slightly out of focus. Beautiful pair. I'll be coming back to this one! | |||

A
nice and wide double star, easily split at this magnification The primary
appeared as a pale orange, almost see through, with a nice blue companion.
The companion was estimated( visual ) to be at PA 90degrees, exactly following.
HS rating 1. This one is a showpiece worthy of inclusion on any star party
list.

A pair which is already
on my list of favourites. The primary shows the typical beautiful orange
color of a variable (= WZ Cas). With a separation of 58" it is rather wide
but also very suitable for small scopes. This time I observed it with my
80mm finderscope @ 19x and with the C11 @ 70x. Both views are wonderful
and show the pair in a very rich starfield.
