Object(s): NGC6749
Category: Globular cluster.
Class:
Constellation: AQL
Data: mag 12.4 size 4 min
Position: RA : DEC :
Description:
This is a challenging object for an 8-inch scope. I could only glimpse it in
averted vision about 30-40% of the time, could not hold it steadily, and could
not easily reacquire it.
The observation was made at a reasonably good site on a night of good transparency and seeing. To improve visual acuity, I used a dark hood while
making the observation. The best view of the object was obtained with a 17mm
Nagler Type 4 eyepiece (at about 70.6x). I could not detect any structure,
central condensation, etc., and could resolve no stars in the object.
The location is relatively easy to pinpoint following guide stars on Uranometria map 105 (2nd ed.) from NGC 6760, a nearby globular cluster which
is much easier to observe with an 8-inch scope.
