New address! 

Untill the 31th of March 2020:

So save the new links!


Astronomy and Corona.

One would think, little connections.
But than again, this is SideWalkAstronomy,
And the idea is to give people the chance to see the sky,
Through the eyepiece of my 10cm telescope.
Many people never did this before,
And are unfamiliar with large telescopes,
Usually touch the telescope with their hands, or with their face.
Both in ways they could pick-up or pass on the Corona virus,
To the next person having a look. Thatís how things are..
I do not want to bring people into danger,
And I don't want to clean my telescope with alcohol,
After every person that had a look, in the dark...
That would be very bad for my lenses, and not safe.
Because of the new government rules, no groups are allowed,
So I can not show groups the constellations,
using a laser pointer, either,
But feel free to mail me any questions!
Did you see a ďnewĒ star, etc. during  your evening dog-walk,
I can try to look it up for you.
Hopefully this crisis will be over soon.
I'll give notice on my website when it's safe again, to do SideWalkAstronomy.

Clear skies! And stay safe!

 Cornelis Zwaan1928 -99


Recomanded : sun space/time


Every month the constellations rise two hours earlier,
12 x 2h = 24h. (= about 4 minutes per day)
At the end of the year we are full circle.

A chart for January 01, 06:00h will show the same constellations as one for May 01, 22:00h etc.

Who alone stretches out the heavens And tramples down the waves of the sea?
Who makes the Bear, Orion and the Pleiades, And the chambers of the south?
