The large star cluster in Coma Berenices called Mel111, accompanied by several galaxies, notably the edge-on NGC 4565 at lower left and the spiral NGC 4559 at upper left. The field of view is 7.5° by 5°, so similar to binoculars. This is a stack of 12 x 6-minute exposures with the Sharpstar 61mm EDPH II telescope at f/4.6 with its reducer (for a focal length of 280mm), and Canon EOS Ra at ISO 800. Sub-frames dithered with the MGEN3 auto-guider. No darks applied. Diffraction spikes added in post for artistic effect.
The Coma Berenices star cluster, aka Melotte 111, at right, with two prominent galaxies at left: NGC 4559 at top left and edge-on NGC 4565 at bottom left. This is a stack of 6 x 8 minute exposures with the SharpStar 76mm apo refractor with the EDPH field flattener for f/4.5 and with the Canon EOS Ra at ISO 800. Diffraction spikes added for effect using Astronomy Tools actions.
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).
