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.
