Hi Hilmar,
>BTW, at what latitude are you located? This affects visibility of some celestial objects.
I'm at 15.1 N (and 145.8 E). Yes, I know about latitude and the position of celestial objects...I studied a bit of celestial navigation, but, actually never put it into practice (as I was usually too seasick when at sea). In any case, GPS is SO much easier (as long as you have batteries and sattelites)!
What is your lat and long?

Special filters from aluminum paper can be obtained (I found that you can replace with the aluminum foil from food packaging, like cereal - double layer for the thickness used here); you can also darken a piece of glass, over a candle.
Thanks, I am aware of that, but always good to pass it on.
BTW, have you ever seen a green flash? it's been a long time for me, but I did see one, from the beach, last week. I guess you wouldn't be able to see it from Bolivia...you need to see the sun set over the ocean I believe.
