I really didn't believe I'd be able to see moons, but my husband had our tiny telescope out and proved it to me. Then the issue was stability with that long lens and my not so robust tripod. I finally upped the ISO to shorten shutter speed and managed this.
I hope to try again and see if I can not blow out Jupiter and raise the moons out. If we get clear skies again! So much rain and clouds here in the midwest.

Pentax K70 camera, Sigman 150-500mm lens with a 2x tele-converter.

I upped contrast, did some noise reduction and sharpening. Little else.
