Comet C/2013US10 Catalina

As from last week till end of february we can observe the Comet C/2013 US10 Catalina. Not a bright comet (magnitured 5à6) but hopefully bright enough to observe with the naked eye. Best timing is around jan 15, 2016 as the comet is closest to the earth. For more information see Comet C/2013 US10 Catalina

High Speed Pictures


Is it possible to take high speed pictures with your ordinary DSLR, like my Nikon D60?
For sure you need light, a lot of light. Secondly you need patience a lot of patience.
Out of my 500 pictures, see my selection of 2 pictures. The water was red colored with a red background, so no color adjustment was made.



My amateur studio.... two tripods, paint, water, background and light.

Grand Tack Theory

The formation of our solar system could explained by the Grand Tack scenario. In this scenario in the early solar system Jupiter and Saturn migrate inwards towards the sun and then back outwards. Those migrations could explain the existance of the Kuiper belt, the Oort cloud but also the late heavy bombardment.

Nacht van de duisternis

Zaterdagavond, 10 oktober 2015, dag van de duisternis. De sterrenkundige vereniging Helios was met 4 leden paraat in Langdorp. De hemel was open maar nevel was een spelbreker. In totaal kwamen een 15-tal bezoekers langs en genoten van het zicht door de dobson kijkers van 8 en 12inch.
Er werd gekeken naar het Andromeda stelsel (M31), de ringnevel (M57), de open dubbele cluster in Perseus (NGC884), de dubbelster beta cygnus (Albireo). Door Danny werden we nog verwend met koffie en koekjes.
