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 The "Tone mapping" method and a new unpublished "VARES" (Variable Resolution imaging method) are very powerful tools for astrophotography.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.

Astronomy Photographer of the Year 2014, Royal Observatory of Greenwich, third place.
Over 2500 images from 51 countries participated.

  • I also got one NASA APOD published (Astronomy Picture Of the Day) at November 15, the Tulip nebula.

  • 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)

I was invited as one of the speakers at the NEAIC conferenceNew 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. 
3D-exhibition in Helsinki, large anaglyph photos, paintings and a movie.

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.

  • Optikfestival in Skara, Sweden


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!

My last imaging project for this Winter season, a high resolution mosaic image of the Heart Nebula


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.

IC 1805, the Heart Nebula is my last imaging project for this season. It's a very high resolution, six panels mosaic image. Image is shot between 20. February and 21. March, total exposure time is 49h. Original size is about 11.000 x 9000 pixels at the scale of one arcsecond/pixel.

INFO

This high resolution photo of the IC 1805, the Heart nebula, is a six panel mosaic. (Original size is about 11.000 x 9000 pixels at the scale of one arcsecond/pixel.) It shows many details in the IC 1805, like the Melotte 15 at the heart of the Heart Nebula. Total exposure time for this narrowband photo is 49h.

The "Heart Nebula", IC 1805 locates about 7500 light years away in constellation Cassiopeia. This is an emission nebula showing glow of ionized elements in a gas cloud and some darker dust lanes.In a very center of the nebula, lays Melotte 15, it contains few very bright stars, nearly 50 times mass of our Sun, and many dim ones. The solar wind, a radiation pressure, from massive stars makes the gas twist to a various shapes.

A globular cluster Messier 3



I have shot couple of clusters at this Autumn season and I have published an image of Messier 13 in Hercules before. My light polluted location is not ideal for broadband targets, like clusters, but with little extra work with processing, they turned to be kind of beautiful. Image is shot at March 17. 2015.

INFO

Messier 3 (also known as M3 or NGC 5272) is a globular cluster in the constellation Canes Venatici. This cluster is one of the largest and brightest and It's located at a distance of about 33,900 light-years away from Earth. M3 has an apparent magnitude of 6.2, making it visible to the naked eye under dark conditions.
