Veil Nebula HaOiiiRgb
The Veil Nebula resides 2,100 light years away in the constellation Cygnus and is one of the best known supernova remnants. Known for it's whispy filamentary structures it's all that remains of a star that was about 20 times as massive as our own. Estimated to have gone supernova some 10,000 years ago it would have been bright enough to have cast shadows here on Earth! It's suspected that before the star exploded it expelled a strong stellar wind, blowing a large cavity into the surrounding gas.
"As the shock wave from the supernova expands outwards, it encounters the walls of this cavity — and forms the nebula's distinctive structures," they added. "Bright filaments are produced as the shock wave interacts with a relatively dense cavity wall, whilst fainter structures are generated by regions nearly devoid of material. The Veil Nebula's colorful appearance is generated by variations in the temperatures and densities of the chemical elements present." ESA

Thanks Brendan, no this is it for now as i just sold my Oiii filter. I've ordered a duo narrowband filter to try it out with my Osc camera. Maybe i'll do a comparison and grab 8hrs with the colour camera.
Kinch wrote: "duo narrowband filter"......interesting idea. Had not heard of this before (had to look it up) - good luck, it may be a winner
For my circumstances it may just be a winner. Very little to lose in trying.

Thanks very much Mike. A great compliment.
