Lat 38°:45.4 N, Long 00°:02.1 W	Catalogue identification	IC 1340 to the left, NGC 6979 (Pickerings Triangle) centre and NGC 6960 (Witches Broom) to the right. Collectively known as the Veil Nebula Complex or the Cygnus Loop. In this image, North is up.
Equipment Used	Takahashi FSQ106N at 530mm focal length, F5.0. Paramount ME German equatorial Mount. Camera SBIG ST-11000M with FW-8L filter wheel. TheSkyX Pro telescope control. CCDSoft V 5.0 camera control. Lakeside Focuser with FocusMax .	Where it is in space	About 3.6° west of 64-Zeta Cygni.
Acquisition	Remote session using TeamViewer control from Ravenshead, UK. Exposures: Lum 18 x 10min. R:G:B each master 10x10 min. Ha:OIII both 12x20 min All sub-exposures -10 or -15°C. All images binned 1x1. Mainly automated sessions using CCDAutoPilot V5.	What it is	At a distance of about 1,500 light years, the nebula is a large supernova remnant from a massive star. It is an expanding cloud resulting from the explosion of the star that occurred ~ 5,000 years ago. It is now about 70 light years across and from Earth this is an apparent size of about 6 Moon diameters in the sky. A 70% crop of the Western Veil can be seen here A 70% crop of the Eastern Veil can be seen here A 100% panorama of the Western Veil can be seen here A 50% resolution image of the whole Veil Nebula Complex can be seen here
Processing Methods	All data reduction with CCDStack. Lum, RGB masters and RGB colour combine prepared in CCDStack.
	Bi-colour Ha and OIII masters prepared in Final LRGB processing using PhotoShop CS6. Bi-Colour NB and LRGB combined and finished in PSCS6
