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.
A telephoto lens shot of the cluster and nebula region of the Cassiopeia-Perseus border, with the Double Cluster at lower right, and the Heart and Soul Nebulas at centre. They are also known as IC 1805 andf IC 1848 respectively. The bright patch off the top right of IC 1805 is NGC 896. Cluster NGC 663 is at top right edge in Cassiopeia. This is a stack of 5 x 6 minute exposures at ISO 800 with the Canon 5D MkII and 135mm lens at f/2.8. Taken from home.
