The image is of the Tulip Nebula and surrounding nebulosity, imaged by myself from my home in Wiltshire, UK. The Tulip Nebula, having official designation Sh2-101, is an emission nebula in the Cygnus constellation, about 8000 light years distant. A micro-quaser comprised of a star and a small black hole is located just to the left of the Tulip. Relativistic jets, very powerful jets of plasma, with speeds close to the speed of light emanate from the accretion disk of the black hole, creating a shock front in the inter-stellar material – this is observed as the blue arc to the left of the Tulip.
The nebula is far too faint to be seen with the naked eye, so requires a telescope with specialised camera, equatorial mount to track the rotation of the earth and a separate guiding camera to accurately control the pointing of the telescope during the long exposures required to capture the details of the nebula. Many of these long-exposure images are stacked to increase the signal to noise ratio and reveal the colour and detail. This image was created using 40 x 20-minutes exposures and 47 x 5-minute exposures for a total of just over 13 hours of exposure. The resulting high-resolution image is 103Mpixels.
The imaging equipment used is a Skywatcher Esprit 100ED Pro Telescope, a ZWO ASI2600MC Pro astro-camera, cooled to -20C on a Skywatcher EQ6-R Pro equatorial mount.
Print size is 60cm x 40cm.
