Here is a view of at least seven of Saturn’s moons taken on August 4, 2018. Two different over-exposed images were used using the ZWO ASI290MC camera and SharpCap software package.

Tech Specs: Sky-Watcher Esprit 120mmED Triplet Refractor, Celestron CGEM-DX mount, ASI 290MC. Captured with SharpCap software and Corel Paintshop Pro.

I asked Tom if he used an occulting disk to blot out the image of Saturn itself, so tht the faint moons would become visible. He said no, adding:

The over-exposure itself causes Saturn to burn right through the image. It’s basically a white hole in the picture.

Thanks, Tom!
