Filaments of the Veil Nebula in natural colors
This is a new version of the Filaments of Veil photo. It shows the nebula complex in visual spectrum. Most strong emission line is hydrogen alpha, H-a, it can be seen as a red color. Blue hues are from an ionized oxygen, O-III.
My latest image is a composition of exposures from several nights, months and years. Couple of weeks ago, when we had some clear night last time, I took couple of shots from Veil Nebula. This time my purpose was to show some rarely imaged details and structures in this complex ball of expanding gas, leftovers from a massive explosion, the supernova.

I combined this new material to my older images of the area. Total exposure time for this five panel mosaic is around 37 h.

Filaments of the Veil Nebula, Part II
This is a new version of the Filaments of Veil photo. Composition is much better now, I think. I added one more panel to the mosaic image and now I have a vertical composition. It's somehow more dynamic and complexity of gas filaments stands out well.

A rare image out of the planetary nebula in Cassiopeia, KjPn8 (PN G112.5-00.1)
Few year back I added this small target in Cassiopeia to my imaging plan. Now we had few clear nights and I was able to finalised a new photo out of it. This is a very dim target and it located just next to famous Bubble Nebula. Total exposure time was around 11 hours for Ha and O-III.

INFO
KjPn 8 (PLN 112-0.1) is an unusually-shaped (14' x 4') planetary (PN) nebula located in the Constellation of Cassiopeia at RA 23h 24m 10s and DEC +60d 57m 30s. It is partially embedded in hydrogen nebulosity from the often-imaged Bubble Nebula complex (NGC 7635, Caldwell 11) and the open cluster, M52, located off the upper right side of this image. North is up and the field is ~ 35' x 35'. Lopez et al. (Astrophys. J, v538, 233-240, 2000) describes KjPn 8 as an "extreme polypolar planetary nebula with a large scale structure characterized by a giant biconical envelope". Steffen and Lopez (Astrophys. J. v508, 696-706, 1998) suggest that the strange tubular structure results from the action of a bipolar, rotating episodic jet whose direction has changed with time. The radial velocity measurements suggest a distance of ~5,200 light years. They suggest that it formed from two distinct and consecutive PN-like events starting with a binary core have stars of similar mass. One event led to the very long structure (NW-SE). The other (NE-SW) extends between the bright pinkish lobes that are enriched in OIII. They further suggest that KjPn 8 may be a rare object in the Milky Way Galaxy.

Eastern Veil in light of an ionized oxygen
A two frame mosaic of the Eastern Veil Nebula was my first imaging project for the Autumn season 2016. For the colour image, I shot three emission lines, hydrogen alpha, Sulphur II and oxygen III. This new image shows the emission of the ionized oxygen alone.

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

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.

Flash from the past, Cederblad 214, the Cosmic Question mark, reprocessed
The new imaging season will start at 5. of September up here 65N. I have been practising my data processing skills by reprocessing some of my older image data. This time the Cederblad 214 got a new processing. Not a big difference to original processing, little better colors and the detail level is somehow higher.
Cederblad 214, the Cosmic Question Mark
Click for a much large image
A detail
INFO
Source: NASA APOD
Towering pillars of cold gas and dark dust adorn the center star forming region of Sharpless 171. An open cluster of stars is forming there from the gas in cold molecular clouds. As energetic light emitted by young massive stars boils away the opaque dust, the region fragments and picturesque pillars of the remnant gas and dust form and slowly evaporate. The energetic light also illuminates the surrounding hydrogen gas, causing it to glow as an emission nebula. Pictured above is the active central region of the Sharpless 171 greater emission nebula. Sharpless 171 incorporates NGC 7822 and the active region Cederblad 214, much of which is imaged above. The area above spans about 20 light years, lies about 3,000 light years away, and can be seen with a telescope toward the northern constellation of the King of Ethiopia (Cepheus).

INFO
Sh2-114 is a complex and unusual HII emission nebula. Its complex, wispy structure is likely the result of winds from hot, massive stars interacting with the magnetic fields in the interstellar medium. But very little is known about it. (Source, https://www.noao.edu/image_gallery/html/im1112.html)
