Image Description and Details :

The Shark Nebula, a large, faint molecular dust cloud in the constellation Cepheus lies around 650 light years distant. The cloud was nicknamed the Shark Nebula since it looks like a shark in wide field images. Within the molecular cloud are several objects. LDN 1235 is a dark dusty patch near the head of the shark. Two beautiful blue reflection nebula, lit up by hot B8IV stars lie above and below. VdB 150 is the top reflection nebula and VdB 149 is the bottom one. Off near the right edge is the galaxy PGC 67671 lying some 50million light years distant. The image was taken at the Okie Tex Star Party in October of this year.Stellarvue SVX 152 refractor at f8, ZWO ASI 6200 camera riding on a Paramount MyT. Image acquisition controlled by the Voyager.

Image Description and Details :

The goal of the image was to go deep enough to show the underlaying dust around this already faint target. Multiple processing techniques were needed to be developed in order to be able to pull out the details on the faintest areas.
