Kemble’s Cascade and the star cluster NGC 1502 in Camelopardalis. The northern portion of the Cascade of stars is cut off at left here. The field includes the southern portion and the star cluster NGC 1502 at the south end of the chain of stars. Taken from home Nov. 25, 2016 with the 130mm AP f/6 apo refactor with the 6x7 field flattener and Canon 6D at ISO 800 for a stack of 4 x 6 minute exposures. Named for Father Lucien Kemble, an ardent deep-sky observer from Canada. Natural haze added some star glows, plus additional glows added with a Gaussian blur layer.
A telephoto lens image of Kuma, a binocular double star in Draco, close together at top here. This is shot to simulate the field of view of binoculars for illustration purposes. The field contains other stars in the head of Draco — Eltanin at lower left and Rataban at bottom. 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.
The very red carbon star, Y Canum Venaticorum, in Canes Venatici, in a closeup at long focal lengths. Astronomer Father Angelo Secchi called this star La Superba. This is a stack of 8 x 6-second exposures at f/10 with the Celestron C9.25-inch SCT and Canon 6D MkII at ISO 800, taken March 27, 2019.
