So Cygnus 2018 is over and all went pretty good! At the first night at Cygnus I took my telescope outside and we started observe deep sky objects from the almost bright sky. We managed to see only the brightest objects as M31, M27, M57 and M13.
We also watched the Moon and Mars.. Here is one of the photographs we managed to take. It is M13, ”the great globular cluster in Hercules”!
When the Moon, Earth and the Sun are in the same line. Earth will cast it’s shadow upon the Moon… It’s called ”the Blood Moon”!
This astronomical event was 27.7.2018 and I managed to locate the Moon from almost bright sky. The Moon was really faint, because when it has risen above the horizon (in Finland), it was already behind the umbra (full shadow). What kind of start for this season!!! 😀
Hello people! There is going to be Cygnus 2018 and it is a big thing in Finland. It´s a meeting of amateur astronomy enthusiasts and there will be people all over from Finland! This time our local amateur astronomy club, Porin Karhunvartijat ry is going to host this event.
Have to say… I´m really getting into amateur radio astronomy and as a ”radio newbie” , I like to try different things and do some experiments with my budget gear. I wanted try to observe the Sun with my ”radio telescope” and I had an deadline for it… and it was ”Cygnus 2018”, because it would be fun to show my fellow hobbyist what can you achieve with a little money and some effort! So did I manage to capture noise from the Sun??? … … … YUP!
What I did was:
First I calibrated my gear towards ”cold sky”. After that I aligned my antenna towards the Sun and received strong signal. Then I wanted to confirm that the signal came from the Sun and aligned the antenna away from the Sun. You can see in the video that the signal weakens in that moment and come strong again when I move antenna towards the Sun again!
You can see the video from YouTube: Sun with rtl-sdr dongle
Used gear was:
- TV-antenna (VHF/UHF)
- The antenna was on the motorised mount: Skywatcher HEQ-5 Pro.
- LNA (+12VDc, 1M-2GHz,32dB, 1=35mA)
- Rtl-sdr usb dongle: NooElec Nesdr mini (25MHz – 1750MHz)
- 12V car battery
- ASUS laptop with SDR Sharp and radiosky spectrograph
I bought a microscope couple of years ago and have been looking tardigrades… just for fun, when it is clouds on the sky. Here is one of them… Which I named ”Joey”.
By the way my microscope is a cheap Bresser Biolux NV–>
But back to tardigrades… These little things can survive almost anything: from the vacuum of the Space, to a cold and warm conditions (really warm and cold). It can withstand radiation: 5,000 Gy (of gamma rays)… People take only 5-10Gy. Grazy huh!?!
Tardigrades are living everywhere on this planet, it is possible to find one from your backyard. Maybe we will find first something similiar like tardigrades from the Space?
Check more from the wikipedia if you are interested: Tardigrade.
I had to wait few months to get doing what I like the most. Living in Finland and being amateur astronomer/astrophotographer is sometimes pretty hard ( when there is almost every bright night a Moon on the sky… or then there is clouds and it rains nonstop for an half of year… And of course what would it be if there weren’t -20-30 Celsius at outside (((Not kidding))))?
But sometimes we get lucky and manage to take 2h 16minutes exposure with ISO1600 from DSO Objects. This is the result of that kind of lucky moment ;).

Andromeda and Moon on the Scale
The Moon and Andromeda galaxy on the scale (visually from the Earth)… You could get Andromeda’s galaxy even more visible with longer exposure time.Both images has been taken with Canon Eos 1000Da and TS-Optics Ed Apo 80/560 f7 refractor. Processing with Pixinsight and Photoshop CS6.
This season has been the most cloudy season that I have never seen! But now, I had some luck yesterday and I managed to take 1h6min exposure of this reflection nebula (Messier 78) in the Orion constellation.
