Jupiter and 5 moons

Posted By Keith Lawson
Was it fainter than the 4 moons? It's possible it may have been a field star. According to my software it looks like it was SAO 138991 at Magnitude 8.99. I didn't have my scope out tonight. Too windy smile

Jupiter and 5 moons

Posted By Keith Lawson
What was the time of your observation? I think Amalthea was only 1 Jupiter radius away from the planet when you were observing Jupiter. At mag 14 Amalthea would have been very hard to see.
