SH2-101, The Tulip nebula. Ths nebula lies in the constellation of Cygnus the Swan in a region named Fish on the platter. I was using my four inch F/6.3 refractor, a Vixen Atlux mount, PHD auto guiding, a set of Astronomik narrowband filters and an Atik 383L mono CCD camera. I captured five minute sub frames with matching dark frames and combined them with flat field frames to reduce the effect of vignetting in the final image. The total exposure time was 65 minutes using a H Alpha filter, ten minutes using a blue filter, 20 minutes using an s11 filter. The O111 filter was taken using 60 second subframes with matching dark frames with a total exposure time of 45 minutes. The arrow indicates what I believe to be the location of Cygnus X-1
