The
great difference in magnitude makes this wide, easily resolved double
an interesting subject. Sparsely
scattered background stars add to the scene dominated by the

pure white, secondary very faint, well split at 50x although
it takes a moment to be seen.

Beta Ser: Sep. 3.66/9.96;
Sep. 30.9". I promised to hold this treat over for later but the
last two eyegaugers convinced me I needed eye relief.
Beta is a blazing Bluish
white star and its shy wide companion does not betray any marked colour
tonight (NB Sky Cat notes a third star of mag. 10.7 but in the next parish
at separation 200.1". I spotted one candidate in a busy field but
was unsure. If anyone finds this one please round it up.)

The video camera is black and white so no color can be noted. This double has a wide separation but the two components have a great difference in magnitude. On the screen it looked like a big snowball followed by a white dot. The final result is an average of five measurements. Theta = 265.1º and rho = 31.06" | |||

Continuing
our theme of wide spaced pairs with high magnitude contrast. The primary
was white, the faint secondary just south of west of the primary.

Very
