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.

Image is in mapped colours, from the emission of ionized elements, R=Sulphur, G=Hydrogen and B=Oxygen.

The Giant Cosmic Squid, Ou4, scale in the sky and a zoom in series

Sometimes it's hard to understand the actual scale and locations of cosmical objects from a photograph. I tend to shoot same objects with a very different focal lengths usually from 200mm up to 3000mm. Form that image material I'm able to build "zoom in series" of the cosmical objects. By that way it's easier to understand the actual scale and location in the sky.
