Dave E Posted October 6, 2022 Share Posted October 6, 2022 Hello from southern Arizona. Brand new to this site and pretty new to astronomy. I tried my first stacking project with Saturn. I'll add a picture. I know I have some work to do but as I enlarged the image, I could see a dark circle on Saturn's rings. I found it again on an image taken in a different field of the telescope. Could this be a silhouette of a moon? I took it Oct. 2, 2022, at 9:53pm. Thank for any thoughts! Quote Link to comment Share on other sites More sharing options...

geoflewis Posted October 6, 2022 Share Posted October 6, 2022 Hi Dave, welcome to the site. I'm not sure that I can see what you are referring to in your images as they are too small and become blurred when I zoom in, so could you indicate where in the rings you are seeing the silhouete?

Nightspore Posted October 6, 2022 Share Posted October 6, 2022 I can see what appears like a shadow. Unless it's the Cassini Division. Seems a bit large to be a minor moon like Pan, which is only around 17 km across. It might be the shadow of a larger moon near the rings. Maybe Janus?

Dave E Posted October 6, 2022 Author Share Posted October 6, 2022 Thanks! Nitespore may be right. I see another smudge on the opposite side. Just the division in a grainy picture. Quote Link to comment Share on other sites More sharing options...

Titan, Rhea and Dione are the only other moons I see regularly with my small refractors. 1 Quote Link to comment Share on other sites More sharing options...
