Veil Nebula in light of ionized oxygen only
This must be the worst winter season ever! Last time we have had clear skies, up here 65N, was at end of the October, almost two and half months ago! Now it's cloudy, -13celsius (~8 fahrenheit) with a storming wind to a top of that. Next ten days will be no better by weather forecast. Few words comes to in my mind but I say only one, frustrated.
Veil Nebula in O-III light only
Click for the large image
This photo of the Veil Nebula supernova remnant in Cygnus shows only an emission from the ionized oxygen (O-III). All the stars are suppressed to show the actual shapes of the ionization front better.
The ionized oxygen, O-III, glows at wavelength of 500,7 nanometer. To a human eye it shows as a turquoise color.
Info
Veil Nebula is a cloud of ionized gas and dust, leftovers from an exploded star. The star exploded some 5000-8000 years ago at distance of about 1470 light years. This, relatively faint target, is difficult to image due the large angular diameter, about three degrees, and a dense star field.

The Veil Nebula in colors
This photo of the Veil nebula shows it in full colors. Colors are combined from the emission of ionized elements, hydrogen, sulfur and oxygen.(H-alpha, S-II and O-III) More info about this photo of mine can be see HERE

Cygnus Wall in visual colors
This photo is originally published at 31.10. last year. At the time I made only a mapped color version of it.
Now I'm publishing the same image in visual spectrum. It's combined from three component exposures of an emission from the ionized elements, hydrogen , oxygen and sulfur. (H-alpha, O-III and S-II) Channels are combined by following method, Red = 75%H-alpha + 25%S-II Green = O-III and Blue = 80%O-III+20%H-alpha (to compensate otherwise missing H-beta emission.)

Image is in visual spectrum from an emission of the ionized elements.
The Red glow is mainly from ionized hydrogen, bluish hues are from ionized oxygen.

INFO
Source: NASA APOD
The North America nebula on the sky can do what the North America continent on Earth cannot -- form stars. Specifically, in analogy to the Earth-confined continent, the bright part that appears as Central America and Mexico is actually a hot bed of gas, dust, and newly formed stars known as the Cygnus Wall. The above image shows the star forming wall lit and eroded by bright young stars, and partly hidden by the dark dust they have created. The part of the North America nebula (NGC 7000) shown spans about 15 light years and lies about 1,500 light years away toward the constellation of the Swan (Cygnus).

At the Spring season of 2014 my old Meade LX200 12" telescope gave up and died. I spent a whole summer season trying to find a way to finance a new setup.
I had lots of troubles, especially with the Meade company. First they contacted me and offered a brand new 14" LX850 for free. Then, after a couple of months, they cancelled everything without a reason. Meade really pissed me off big time, somebody might call it to a fraud! The false promises from Meade side cost me a lots of money, time and energy.
After all the troubles everything went well. I got great supporters from high end manufacturers and retailers. The new setup was up and running at mid October 2014.

All images are taken with the Canon EF 200mm f1.8 lens, QHY9 astrocam and Baader narrowband filters by using a Meade LX200 GPS 12" as an imaging platform. After the last image of the Spring season, the ten panel mosaic of Cepheus at middle, the old Meade fried permanently.

- The Telegraph selected my photo as a one of the best amateur astronomy photographs of the past four years.
- Suomen Kuvalehti wrote a large article at the last issue of the year 2014 about my photographing, eleven pages total. (SK 51-52 19.12.2014, pages 1 and 42-51)
- Daily Mail published an article about the experimental 3D conversions of my astronomical photos.

This is a looped video, click to start and stop. This is an experimental test with a 3D-conversion of my astronomical images. Only real elements from my original image are used, there is nothing added but the volumetric information!
- I was invited as one of the speakers at the NEAIC conference, New York, Spring 2014.
- Two large public artworks from my photos get revealed at 2014. A very large, over 10 x 3m, photographic print on aluminium "Cirrus of Cygnus" and the "Path of Swans", 4 x 2m, on aluminium. Beside public works, many of my photos ended up to a private homes.
Path of Swans, 4x2m
Cirrus of Cygnus 10x3m, the large mosaic image is a very sharp even in this scale.
- I participated to two art exhibitions with my astronomical photos, one in Helsinki and an other here in Oulu.

- One of the most interesting tasks at 2014 was a cooperation with the vocal ensemble Cappella pro Vocale. This cross art production was a mixture of an old vocal music and the astronomical images. The production took place at the church of St Thomas. My photos get projected with three powerful projectors on walls and sealing and everything was matched with the music carefully.
