Urania Closing the Year

This morning Observatory Urania organised their annual closing meeting. After the presentation on administrative aspects a very interesting overview was given on art and astronomy from ancient history uill today.
Once completed, participants from last year's lectures received their certificats ... including myself as I attended Astrophysics.

ATT Essen - Review

Kokerei Zeche Zolverein Essen - Located behind ATT parking spot 

It was my first time ever that I did visit the ATT Essen. It's the biggest European fair for amateur astronomers with both commercial trade and second hand material.
I arrived around 9h45 with plenty of parking space. Arriving at 10am the Gymnasium am Stoppenberg, the entry was blocked with a long waiting row. But 15 minutes later and paying 6 euro entree fee, I could enter the astro arena.
On my way in I did meet with collegues from Astroclub Urania from Hove (Antwerp).

A lot of variation of astro stuff, second hand material and also new equipment -  a total of more then 80 participants. During the day it was also possible to attend some seminars. I attended a lecture on "what an astro beginner need to start with" provided by the local astro club.

Personally I was interested in color filters, red dot finders, wide field oculars and a small apo OTA. At the end I bought one baader "yellow" color filter (as they did not had the color filter series available) and the SkySurfer 3 red dot finder.

I left the fair around 4am and took the time to visit the old mine site located behing the parking spot. This area is UN World Heritage Site and the site was once a very productive and modern mining site.

Some pictures taken during my visit of the site.

ATT Essen

Quit Sun

Today we had an open and clear sky and thus more then 14h time to observe the sun. Observations were done using my PST40. It was a quit sun without sunspots and two small prominences of which one was more bright then the other one. Both are located at east of the sun (location 4h).

Picture was taken afocal with 8-24mm lens on 24mm. Editing completed using CS4.
