NGC 663 (left of centre) and M103 (bottom right) open clusters in Cassiopeia. NGC 654 is at upper centre and NGC 659 bottom centre. Faint cluster IC 166 is at far left. Taken Nov 5, 2010 with 105mm A&M apo refractor at f/5 with Borg .85x flattener/reducer and Canon 5DMkII at ISO 800 for stack of 4 x 10 minute exposures, Median combined. Used Celestron CGEM mount and Sky-Watcher SynGuider on William Optics 66mm guidescope. All seemed to work well.
Clusters in Cassiopeia: upper left: NGC 654; middle left: NGC 663; lower left: NGC 659; lower right: M103.
The classic edge-on spiral, the Sombrero Galaxy, Messier 104, in Virgo. This object is always low in my home sky so tough to get a clean, sharp image of it, but this night, April 20, 2020, was as good as it gets for me. It looks like there is a little asteroid trail to the left of M104. I left it in. This is a stack of 6 x 10-minute exposures with Astro-Physics 130mm apo refractor at f/6 (with the 6x7 field flattener) and Canon EOS Ra camera at ISO 800.
