The constellation of Cassiopeia the Queen, framed with the 85mm lens and including many star clusters: M52 at right, the Double Cluster at left, and M103 and NGC 457 on the left side of the W of five stars that marks Cassiopeia. The Heart Nebula, IC 1805, is at upper left, and the Pacman Nebula, NGC 281, is at lower centre. This is a stack of 4 x 2-minute exposures at f/2 with the 85mm Rokinon lens, and modified Canon 5D MkII at ISO 1600. A final exposure taken through the Kenko Softon A diffusion filter adds the star glows. Taken December 11, 2017 at the Quailway Cottage in southeastern Arizona near Portal.
Cassiopeia, with the 135mm telephoto lens, at f/2.5 for a stack of 6 x 2 minute exposures with the Canon 5D MkII at ISO 800. Plus star glows added with a layer of 2 x 2 minute exposures with the Kenko Softon filter. Field is similar to binoculars. Taken on a frosty night Feb 6, 2013, using the new iOptron SkyTracker tracking platform with the iOptron ballhead. It worked very well, though another 4 shots taken in the series were trailed slightly. 6 were fine.
