Messier 3, the globular cluster in Canes Venatici, in a moonlit sky. This is a stack of 16 x 4-minute exposures through the SharpStar 140PH apo refractor at f/6.5 with no field flattener or reducer, and using the Canon EOS Ra camera at ISO 400 with an Astronomik CLS light pollution clip-in filter. RC Astro Gradient Xterminator and StarShrink filters also applied. While it would be possible to neutralize the sky colour I kept the blue moonlight, again for artistry.
A telephoto lens image of the globular cluster Messier 3 in Canes Venatici. This is shot to simulate the field of view of binoculars for illustration purposes. The faint globular cluster NGC 5466 is at far left. This is a stack of 6 x 1-minute exposures with the 200mm lens at f/2.8 and Canon 6D MkII at ISO 800, tracked but unguided on the Mach 1 mount, on April 28, 2019.
