Description

While viewing the Propeller Nebula with my Gen3 night vision eyepiece, I was struck by the wisps of nebulosity that pervade the area. To my eye, they resemble cirrus clouds commonly referred to as Mares Tails. As wonderful as I found them, there are very few wide field images of this region of northwestern Cygnus. People usually go in tight for Simeis 57 (aka the Propeller Nebula) or perhaps IC1318(b). I was going to title this image something like "The Neglected Mares Tails of Northwestern Cygnus".

As I was finishing the processing, the image of a horse head absolutely jumped out at me. It is so large it covers the left 1/3 of this image. After some thought, another large red horse came to mind, perhaps the greatest athlete of all time: Secretariat. So it seemed only fitting to name this the complex Secretariat Nebula.

Of course the cataloged objects previously mentioned - Simeis 57 and IC 1318(b). But at the scale this image is shot, they are fairly minor players.

My initial thought was to do an SHO image. Sii pervades the region, but the Oiii signal is very weak - only a bit around Simeis 57 and IC1318(b) so I went with HaRGB.
