All my photos from the year 2018
A poster format collection of my photos from the year 2018. The Spring season 2018 was very cloudy, the Autumn season 2018 was kind of good and I was able to finalize couple of long imaging projects.
All my photos are taken with my current setup, the main instrument is an excellent imaging scope Celestron EDGE HD 1100 with a 0.7 focal reducer from Celestron. That's simply a best reducer I have ever used! (Some optical testing can be seen HERE)
The mount from 10-micron is a top performer too. All images are taken with Apogee Alta U16 astronomical camera and Astrodon narrowband filter set, H-alpha 5nm, S-II 3nm and O-III 3nm.

I do purely narrow band imaging since my observatory is located at downtown of the City Oulu.
So far the light pollution has been massive in this industrial city with about 200 000 inhabitants but it used to be mostly from narrowband light sources, like old sodium and mercury lamps. Now the most of the light sources have been updated to LED-technology and it makes the light pollution much worse, since LEDs are emitting light at full spectrum. The broad band light from LEDs is practically impossible to filter out. I need to find a new location to my observatory during the Summer season 2019.

Astro Anarchy gets published, the cover picture of an Official Vatican Observatory calendar 2019
My photo of the Sharpless 115 (Sh2-115) and a planetary nebula Abell 71 get selected as a cover photo of an Official Vatican observatory Calendar for the year 2019.
A Square Degree of Birth and Death
This photo shows about one square degree of sky from the constellation Cygnus. In this photo, there are both, birth and the death.
The blueish area at middle up is a stellar nursery, new stars are born there as an ongoing process.
The blue dot at lower left is a planetary nebula Abell 71. The star has consumed all of its hydrogen resources and then blowed out its outer layers.

Grande mosaic of Cygnus in visual colors, 18-panels, 150 hours and 22 x 14 degrees of sky
Yesterday I published a mapped color version of this nebula complex, here is the version in visual spectrum.
I have originally published this image back at December 9, 2011 After that I have shot many details out of this are of sky with much longer focal length instrument. Mainly with Celestron Edge 11" reflecting telescope. I have now updated this photo with a new image material and I thought, that it's a good time to republish this updated image again.
The Great mosaic image of constellation Cygnus has 18 individual panels stitched together seamlessly. Each panel has shot three times for a color image. First I shot the light from an ionized hydrogen (H-alpha), then light from an ionized sulfur (S-II) and last the light from an ionized oxygen (O-III). The final image has a resolution of 15.000 x 10.000 pixels. I shot all frames with the Canon EF 200mm f1.8 camera optics at full open, QHY9 astrocam and Baader narrowband filter set.
There are no noise reduction, star reduction or sharpening used for this mosaic. It's very well in focus due to temp compensating focuser I made for this lens. (At f1.8 the critical focus zone is about 7 metric microns.)

Wonders of Swan
I have made a collection out of the photos I have shot from this area of the sky. I have used 517 hours of exposure time to capture details from Cygnus between 2009 and 2018. I used this material to update my mosaic image of the Cygnus constellation.
