I find identifying moons to be the most exciting part of planetary viewing and I am always pushing the limits of my scope...

Last night 8-19-2018 I was studying Saturn and was able to see Rhea, Tethys, Dione, Titan and Enceladus just barely through Saturns glow.  But on reviewing my sketches I noticed a very dim speck right were Hyperion should be!?!  I have clear dark skies out here in the rockies that allow me to see objects below 15 magnitude through my 14" (even a few moons of Uranus), but nothing this small.

My question is this.  Has anybody out there ever seen Hyperion before?  I really want to add this one to my list but I'm skeptical.  Especially with a half moon so high in the sky!

Assuming that you have verified there were no other field stars as bright or brighter near the same position, then you most likely saw it.  waytogo.gif  It is well within range of your scope even with the Moon up and is generally well separated from the planet.  The difficulty is in identifying it against the busy background. 

 

It is nearly the same magnitude as some of Uranus' brighter moons.
