Hi Jimmy,
Intriguing!
I "moused around" in two different browsers and nothing happened.
I finally found this: http://www.astrodwarf.com/deep-sky/detail/8215
which says coordinates of Archinal 1 are:
RIGHT ASCENSION: 18h 54m 32.82s
DECLINATION: 5° 33â² 68.4â³
Nova.astrometry.net says the center of your image
is precisely:
Center (RA, hms): 18h 54m 54.692s
Center (Dec, dms): +05° 31' 33.062"
and that the orientation of your image is this:
Orientation: Up is 103 degrees E of N
so you are right on the money.
I think you might indeed have the first posted image of this
area!
I wonder how somebody decided that was a "cluster?"
There is an almost better candidate of 5 slightly brighter
tightly grouped stars to the left.
Thanks,
Howard
