B&W space, Winter 2014-15
As astronomical cameras are usually cooled grayscale CCD-cameras, color images are made by shooting each color channel through a filter. For broad band RGB images usually four filters are used Luminance and RGB-filters. Due to massive light pollution in my location, I'm specialized to a narrowband imaging, it's very effective method to shoot emission nebulae, since they are emitting light in well known wavelengths. All other light can be then filtered out and let just the right wavelength pass through. I'm using the most common combination of emission lines, a light from ionized hydrogen (H-alpha), sulfur (S-II) and oxygen (O-III).
The strongest emission line is usually the H-alpha, it has most of the details also. I'm publishing here a collection of H-alpha images from the Winter season 2014-15. Sometimes B&W images can be very beautiful.

Melotte 15, a new revision
I did some minor tweaking with the Heart nebula project. This is a new version out of the
Melotte 15 area at the heart of the Heart, IC 1805.

All my new astronomical photos from the Winter season 2014-15
My humble thanks to the supporters, they made my work possible at this Winter season!
First class products and service
This is a collection of my photos from the past Winter season. We are now out of astronomical darkness for about six months due to high latitude, 65N. As every time, it's hard to give up imaging the beauty of the deep sky.
The season was very cloudy too. We had over three months a solid cloud cover this winter and clear nights just now and then. The good side is, that I have been forced to develop new imaging and processing methods to be able to finalise maximum number of photos. The "Tone mapping" method and a new unpublished "VARES" (Variable Resolution imaging method) are very powerful tools for astrophotography. I'll publish the VARES.method in a year or so, after I have tested it well enough.
All of my photos are taken from a light polluted downtown.

- 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.

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 another 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.

Interior of the shop, they have a large stock of products on site.
I had a pleasure to be invited as one of the speakers in "Optikfestival Skara", Sweden. The happening was organized by a Astrosweden, a largest optics retailer in Sweden. They are specialized to Astronomy, nature photography, hunting and microscopy. I was really impressed by the passion and knowledge they have about the the optics!
