[vsnet-alert 9906] DA55 aka QSO B0133 +47

[Chris Jones]

Based on my recent attempts to observe this object visually with a 0.46m 
reflector it is just above 16th magnitude and very difficult to separate
from the two c16th magnitude close companions that John Greaves comments
upon.

I've been using a USNO A2.0 sequence which appears to be a little faint 
in this field. With a Henden sequence I will typically reach mag 16.3-16.5
whereas in this field against USNO 16.0 can only be glimpsed.

If anybody is aware of a better sequence I would be interested.
