Description

M45 – The Pleiades – My Second DSO

Here is my second attempt at a DSO, Messier 45, the Seven Sisters open star cluster, located 444 light-years away it is the closest star cluster to Earth.

My plan was to shoot 20 images and stack them but thin clouds rolled in and I only got 16 images. My settings were ISO 800, 30 seconds, f/5.6 on the 250 mm Canon telephoto lens with the modified Canon T7i camera using the Skywatcher All View Alt/Az mount. I started shooting around 9 PM.

This is not an award winning image but I am pleased with the outcome. I am getting a bit better each time out. This was shot with a 77.8% Moon trailing.
