Ones again, it's overAstro Aanarchy

I feel sad to say good bye for my addiction for nearly a six months.

Astronomical darkness will end at 08.04. officially but at the moment we have only couple of hours darkness so there is not much point to do any long exposure imaging any more. Here, at 65N, we'll have next dark night at 06.09. 2012 and just for about two hours.

All my images from the Autumn/Spring seasons 2011-2012 as a poster

Autumn season 2011

The main work for the Autumn season 2011 was the very large 18-panel mosaic of Cygnus constellation.

Original blog post, with technical details, can be seen here:

I have no a large photographic print on my wall, image here:

Spring season 2012

The main work for the Spring season 2012 was a mosaic image too, a 12-panel mosaic of constellation Auriga. Original blog post can be seen here:

Tools used

I shot everything in this imaging period with my camera lenses. At first with the Tokina AT-X 300 f2.8 and most of the images with Canon EF 200mm f1.8, after I managed to fix the orthogonality issue between the CCD and the lens. All images was taken with QHY9, a cooled astro camera, and Baader narrowband filter set. (H-a, O-III and S-II)

Summer time

I will update my blog regulatory during the Summer season though. I have considered about renting a remote operating scope now and then, if I'll find funds for it. An naturally I will publish my experiments too and fine tune equipment's and work flow.

Some of the publications from the season 2011-12

At end of the Spring season I had my first exhibition about astronomical imaging in Oulu Museum of Art.

There was about twenty or so large framed prints to see and one lecture for interested. I have hardly any images of the event, here are some bad ones with mobile phone... Unlike seen in images, there was actually lots of visitors.
