Year 2017

Overall the year 2017 was very cloudy up here 65N. Due to very high latitude we have only six months of usable astronomical darkness. Light pollution is increasing year after year. My observatory locates at roof top of the building in very centre of the city of Oulu. I can shoot only narrowband data from my location due to intense light pollution. In pas years the old mercury and sodium lamps has been replaced with new LED-lamps. The light from old lamps, yellowish glow, has kind of narrow band width and my 3 nm filters easily filter it out. The new LED-based lightning system emits light at very wide spectrum and even photos taken with 3 nm filters shows some artefacts from light pollution. At the same time the total amount of light power has grown year after year. That means a very bright future to us children of night.

-Sharpless 119 in Cygnus, project finalized




I have published three photo posts about my Sharpless 119 (Sh2-119) imaging project so far.
The first one was this photo at November 8, IMAGE LINK
The second one was a two frame mosaic, IMAGE LINK
The third one was a two frame mosaic in visual colors, IMAGE LINK

We have had very few clear nights at this Autumn season. I have managed to use them all so I was able to have enough data to finalize this six panel mosaic image of Sharpless 119.

A very high resolution photo of Sharpless 119, original resolution is about 12.000 x 8000 pixels.
Image is in mapped colours, from the emission of ionized elements, R=Sulphur, G=Hydrogen and B=Oxygen. The photo covers about six square degrees of sky. (The full Moon spans about 0,5 degrees of sky.)

INFO

Sh2-119, Sharpless 119, is a large complex of emission nebulosity in Cygnus constellation, about 2 degrees east of the North American Nebula. It is located just around 68 Cygni, a quite bright star of magnitude 5. (The most bright star in the photo) This target is not very commonly photographed due to a close proximity of brighter and well known targets, like North America and Pelican Nebulae.

Sharpless 119 can be seen at lower left corner. The white rectangle shows the location of  my new mosaic photo. Sh2-119 spans about three degrees of sky horizontally. (The full Moon spans about 0,5 degrees of sky.)
This photo was taken with the Canon EF 200mm f1.8 lens and the QHY9 astrocam, Baader narrowband filter set at 2012.

Sharpless 119 in Cygnus, visual spectrum version


Since beginning of September we have had three clear nights. This Autumn season has been the worst in twenty years.

I made a visual color version out of my two frame mosaics of Sharpless 119 (Sh2-119). You can find a mapped color version from HERE. My aim is to make a six panel mosaic of the whole area of the Sharpless 119. At the moment it's not possible due to weather up here.

Sharpless 119 in Cygnus, project continues



I have published first photo out of Sharpless 119 at 8.11. 2017, since then we have had a full cloud cover. Yesterdat we had about three hours of clear skies and I was able to shoot an other frame next to first one. My target is to make a six panel mosaic image out of the whole Sharpless 119.

A miss shot



Now and then something goes wrong... Especially when the target is very dim, it's very easy to miss the whole target while aiming to it.
I was shooting my first light for the Autumn season 2017 and I thought that my telescope was centred to the WR 134. It was not, instead I shot some dim filaments of gas and lots of stars next to actual target.

Not much a photo but I didn't want to waste three hours of exposures so I made this image out of them. Color data is borrowed from my older mosaic image of the area.

WR 134, Ring Nebula in visual colors


I have published a mapped color version of WR 134 in Cygnus. Now I have made a visual color composition out of the narrow band channels, H-alpha, O-III and S-II. This composition is very close to a visual spectrum. The most powerful emission is from ionzed hydrogen, H-alpha. It emits light at red wavelength as well as ionized sulfur, S-II. Ionized oxygen, O-III, can be seen as blue color. There are very few photos out of this object. There are total 33 hours of exposures in this composition.

INFO

This image shows a ring-like nebula traced by the glow of ionized hydrogen and oxygen gas. Embedded in the region's interstellar clouds of gas and dust, the complex, glowing arcs are sections of bubbles or shells of material swept up by the wind from Wolf-Rayet star WR 134, brightest star near the center of the frame. Distance estimates put WR 134 about 6,000 light-years away, making the frame over 100 light-years across. Shedding their outer envelopes in powerful stellar winds, massive Wolf-Rayet stars have burned through their nuclear fuel at a prodigious rate and end this final phase of massive star evolution in a spectacular supernova explosion. The stellar winds and final supernovae enrich the interstellar material with heavy elements to be incorporated in future generations of stars.

Sharpless 119 (Sh2-119) in Cygnus




This is my second light for the Autumn season 2017. This is a detail of the large emission area just couple of degrees from the North America nebula. It's very overlooked due to its low surface brightness and a close proximity of brighter and more famous emission targets.
I have plans to shoot the whole nebula as a mosaic of six image panels, when ever the weather permits.

First light for the Autumn season 2017, finally!


This Autumn season has been the most cloudy one, I have never publish my first light so late.
We have had only one clear night plus two nights with opening at clouds for few hours.  

My first light for the Autumn season 2017  shows a rare and exotic target at Cygnus. It's a largely unknown Wolf-Rayet shell around the star WR 134.
I noticed this formation at first time in my large 18-panels mosaic of Cygnus. It's clearly visible, specially at Ionised oxygen channel (O-III)

The central Cygnus as a cinemascope format image set


I have worked with a cinemascope format movie from my photos for a movie theatre presentation. This is an extra wide ~21:9 format used in 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,
