Jupiter and Saturn on Dec 23

Canon 1100D with Meade LX-90 8″ scope, ISO 6400, 1/15 second at 21:51 ACDT (click image to enlarge)

The two planets are slowly separating, tonight to 13 minutes of arc, around one fifth of a degree, up from 6.5 minutes of arc on Monday night.

My main goal tonight was to share the view with Karen, who worked the previous two nights, before Jupiter and Saturn are no longer in the same low power field of view. She enjoyed it.

I didn’t have a lot of time for set up and imaging tonight, but wanted to take an image that emphasised the planets themselves rather than their moons. The focus is not great, and Jupiter is still overexposed, but I like the fact that Saturn’s ring and the planet are distinct here.

The good news is that I have my Meade LX90’s AutoStar back from repair now, and it works well! This will encourage me to start doing tracked, piggy-backed, wide-field photometry again. It’s been awhile.
