Eastern Veil as a cinemascope format photo
I have worked with a cinemascope format movie theatre presentation from my photos. This is an extra wide ~21:9 format used in movie theatres. The actual film is not ready yet but I have some of my images converted to this ultra wide format. I think they will look great at a large movie screen! I'll publish some of individual panoramic format photos here, images are down scaled for the web.

INFO
Eastern Veil is a part of theVeil Nebula supernova remnant at constellation Cygnus.
Veil Nebula is a cloud of ionized gas and dust, leftovers from an exploded star. The star went off some 5000-8000 years ago at distance of about 1470 light years. The whole Veil Nebula is a relatively faint target and difficult to image due to the large angular diameter, about three degrees, and a dense star field.

A little different view to the North America nebula, part II
Yesterday I published a new photo out of the North America Nebula. I had some extra exposures for it since at first I used a wrong image position. Images are overlapping so I was able to build a small two panel mosaic.

A little different view to the North America nebula, NGC 7000
I have planned to shoot this area of the North America Nebula for years. NGC 7000 is very well known and much imaged area of the sky. I always trying to find new visual aspects from the popular objects. Nebula itself is relatively bright, only five hours of exposures was needed for a good signal.

First light for the Autumn season 2016, Eastern part of the Veil nebula supernova remnant.
This is an opening shot for the Spring season 2016, it's good to be back again!
This time I shot a two frame mosaic out of the Eastern part of the Veil Nebula SNR. This image shows well the complex nature of the shock front sourced by an exploded star, a supernova.
Total exposure time from several nights is around 15 hours.
