Description:
Tonight after 2 hours with Jupiter and another 1/2 hour with NGC 2158, I was
anxiously awaiting for Leo to try out my new Galaxy Grabber eyepiece, the 12mm
TV Radian. So tonight, it's open season on the Lion ;-) and the Light Cup
picked the Hickson 44 group, NGC 3185/3187/3190/3193 with magnitude
12.7/13.1/12.0/12.0 to start the galaxy season with. Note that these galaxies
are aptly located at the neck of the Lion ;-). The objects were about 45 degree
above horizon. Seeing has deteriorated with breeze, light pollution, etc.
Although precisely located, these galaxies were nowhere to be seen at 22x. I
thought I caught a glimpse of a faint patch some distance fromthe mag 9.6 star
SAO 81279 at 30x. Ah, but the Galaxy Grabbercaught NGC 3190 at 73x, extremely
faint and slightly elongated.NGC 3193 can now be seen but looked dimmer. The
best view was at110x with the Planetary Nebula Plucker (8mm Radian). Stellar
corescan be seen in both NGC 3190 and 3193. NGC 3190 is definitelyelongated
while NGC 3193 is definitely round; again 3190 seems a little brighter. Both
galaxies stayed in the same FOV even at110x. What strike me was how tiny these
two galaxies looked. I spentclose to 30 minutes trying to find NGC 3185 and
3187. Alas, it was not meant to be; I simply need a darker sky away from houses
and people :-(. Unfortunately, I forgot to look at R Leonis (supposedlya deep
red variable star) and see if the TV-102 had spilled any blood ;-).
Thus began the galaxy season for the TV-102 Light Cup and I can see now that it
would be a good hunting season indeed ;-).
