After the great succes of
the MK-67 on Epsilon Hya (with DI 94.3) I went over to Bu 24.
The 1.2" seemed to be a nice try for the scope, and the DI of 91.4 is in the same range. But, Bu 24 is considerably lower in the sky then Epsilon. With an altitude of 25° Bu 25 is in the danger zone, the zone where we expect no seeing and where we get dimmer images... The result was corresponding. Only a faint, fuzzy ball was seen. Although the ball was much larger then a star should be, there was no sign of duplicity. |

Nothing doing at low power,
at mid power slightly elongated, and definately elongated at high power
with the split popping in and out of view. To be truthful, I wasn’t sure
if this variability was due to the seeing, which otherwise seemed to be
pretty good tonight, but rather my eye. The pair lies close to the N-S
line and there might be a tinge of blue, but hard to tell.

Brief moment of elongation
noted at 360x. Watched star for further 10 minutes without success.
Observation was too brief
for any worthwhile comment. Though the scopes ability to attack a separation
of 1.2 suggests the equipment is in excellent working order. It also suggests
observers with larger mid range focal length reflectors should be more
adventurous with their observing practices.

I approached this with no
great expectations. No sign of duplicity @80x or
145x. Elongation @230x at the anticipated position angle with occasional narrowing of the centre into a thick figure of eight. There seemed to be an almost orange/red tint in the direction of the secondary Isolated in the fov at all magnifications. Rating (1(best) - 5(worst))
: 3

Not conclusive at all. 130/1000
might be needed here.
White and white/yellow.
Tight. Suspect slightly wider than quoted 1.2". Cleanly split
at 200 X and higher powers. Suspected at 150 X. There are a few of
nearby doubles in the field around this double. PA approximately
180 degrees.
