The Coma Berenices star cluster, aka Mel 111, with star glows added from haze in the sky to accentuate the star colours. The edge-on galaxy NGC 4565 (the Needle Galaxy) is at lower left; the spiral galaxy NGC 4559 is at upper left. Several other smaller NGC galaxies are in the field, which is similar to the field of view of binoculars. This is a stack of 7 x 4-minute exposures in a clear sky blended with 2 x 4-minutes with the haze moved in, all with the Sharpstar 61mm EDPHII refractor at f/4.5 and Canon EOS Ra camera at ISO 1600 (with no filters used). Taken April 1, 2022 from home.
Comet Hartley 2 near the Pacman Nebula, NGC 281, in Cassiopeia. Stack of 4 x 6 minute exposures at ISO 1600 with Canon 5D MkII on A&M 105mm apo refractor at f/4.8 with Borg reducer/flattener. Bright star is Alpha Cas, Schedar. Autoguided with Celestron NexGuide autoguider. However, image of comet core is from only one exposure to minimize trailing from this fast-moving comet.
Comet Hartley 2 on October 7, 2010 as it approached the Double Cluster. Stack of 5 x 6 minute exposures at ISO 1600 with Canon 5D MkII on A&M 105mm apo refractor at f/5.1 with Borg reducer/flattener. Autoguided with Celestron NexGuide autoguider. However, image of comet core is from only one exposure to minimize trailing from this fast-moving comet.
