We had clear skies last Thursday (2020/02/06) and had many of the Societies Dobsonian telescopes out, a couple of members bought their own telescopes (both reflectors) and Leigh Slomer produced this image of the Great Orion Nebula (M42).

About a dozen members used the 16" telescope over the Christmas period with Keith providing a demonstration of the set-up and use of the new CCD.

The evening ended with cloud relatively early but they did get 10 light frames and below is a stack of these using Astro Pixel Processor.

After checking out spaceweather.com for any astronomy updates yesterday, Honor couldn't believe the Sun had finally got some sunspots. Being up early anyway to walk her Mum's dog, she got home and got her ED80 refractor set up on an EQ3 and took some photo's.

This is the meteor report for November 2019, by the Crayford Manor House Astronomical Society Dartford.

This month we were plagued with poor weather and this is reflected in the low number of meteors captured.

In total we observed 139 meteors from 29 different showers, none of these showers was particularly active, the most active being the Leonid’s where we captured 19 meteors compared to 55 sporadic meteors in the Month.
