Hoover's C8 set up for a clear night

Sofi1999: Total eclipse over Germany

Probably the largest telescope in Herford: this dome houses a C14 on top the "Friedrichsgynmasium". It's open to the public if skies are clear, but check with this site first
Welcome to my Astronomy pages. As you can see they are under construction at the moment, after dwindling around on some lone corner of my former home page displaying nothing more than an ancient hubble deep field picture. On the left, you can see the instrument I use for observing: A Super Polaris C8 which I bought from the States back in 1994 or so from wholesale optics of Pennsylvania, which later turned into Pocono Mountain Optics and then sadly went out of business, I believe.

I have been interested in Astronomy for nearly as long as I can remember, and while my observing activities have lessened a bit over the last couple of years I still lug out the scope on a regular basis. The area of Germany we live in is rather rainy to say the least, so even when we do get a clear night every once in a while our view of the night sky is severely hampered by street lights from the surrounding neighbourhood, so even at the best of times the limiting mag never gets much better than 4-5m.

SoFi1999

One of the major astronomical events of the last decade in Germany was, of course, the total solar eclipse in August 1999. I had been looking forward to this event since my childhood days when I would not have to travel over half the planet in order to view the totality, but life is what happens if you have other plans. And so it happened that my wife Ulla was pregnant with our second kid "Hannah", only a couple of days from giving birth, so we could not travel the 500km (about 300miles) or so that would have been required to reach the totality zone down in southern Germany1.

So, for us it was still only a partial eclipse, although at over 90% occultation, it was still very impressive especially as much of southern germany was clouded out. For the event I set up my C8 on the local primary school's backyard so the kids could take a look, too. The pictures can be found here.

NEVER USE THE SOLAR PROJECTION METHOD with your C8!!! I cannot emphasize this enough, and my telescope got away undamaged because there were some clouds in the sky the let the inside cool down every once in a while, and of course the occulted sun. I put on the primary cover for a minute or two every other minute to allow additional cooldown, too. However, this is no way to observe a fully unobstructed sun, esp. in Summer!

1: as it happened Hannah wasn't born until Sep. 1st, 1999, so I could have gone anyway, but hindsight is always 50/50 as the saying goes ;-)
