In the constellation Andromeda you can see an unbarred spiral Galaxy known as NGC891. Visually it's difficult to see and shows up as a very faint blur. I took some pictures at the moment the moon was 98% illulinated. That's why the picture is not really dark. The galaxy is loacted at a distance of 30 million light years from Earth. This is 15 times further then the Andromeda Galaxy M31.
The picture was taken with my nikon D7500 on TALAPO80/480 f/6. Darks are included and stacking with DeepSkyStacker. Final editing in CS4.

Geostationary Satellites
When looking at the pictures I made of the planet Neptune, I noticed a couple of traces. Most probably these traces are satellties, interesting to notice is the fact the pictures shows three "satellites" 'in line'.
Weather Summary September
September was a warm and dry month with only 28 liter of rain /m2. Interesting to see is the 1 air frost day on September 30th. This is first air frost day since 2014.

Arecibo Message
On November 16th, 1974 the Arecibo telescope was used to send a message in the direction of the Hercules constellation. More specific in the direction op Globular Star Cluser Messier M13.
M13 contains approximately 300.000 stars and is located at a distance of 25.000 light years from Earth.
The message is build around 1679 pulses of binary codes (zero and one's) and contains information about our numerical system, chemical elements, human beings, our planet, our solarsystem and the telescope itself. It was sent by the Arecibo telescope using radio signals.
