Saturn Near Full Tilt

Saturn’s rings are at their widest tilt for the year this month (September 2018), at 26.3°, just short of last year’s maximum tilt of 26.98° (October 2017).

The planet was at opposition just two months ago (15th June 2018) and is still a grand view through the eyepiece.

This image was composed from a four minute video exposure, using the digital crop feature of my DSLR camera. I took a second video using a 2x Barlow but the resulting image was inferior to the above.
