Astrophysics Course at Urania

Today I attended the first lesson of astrophysics. This new course is given by Urania in Antwerp each tuesday evening for the next 10 weeks.
The auditorium was full with about 40 people.

 In this first lesson an introduction was given to mathematics describing linear algebra, complex numbers, trigonometry, calcalus, ...

Very Cold Observation testing SE 9mm 100° Ar purched ocular

Clear sky and moderate seeing this evening and very cold with temperatures up to -8°C. 

Observations done using Dobson OrionXT12 and my new Ocular. This is a Scientific Explorer 9mm 100° wide angle, argon purched and waterproof consisting of 9 elements. It was bought directly from Bresser in Germany.

Observations done on M1, M35, M36, M37, M38, M42, M43, M81 and M82. Also the moon was with 41% a perfect object for testing. I'm very happy with my new ocular and the starclusters are showing up very bright and sharp. The 100° wide angle and field of view makes it necessary to have your eyes travel around to see all the details. Very good quality, good contract and bright immense view. The ocular was delivered safely in a nice big box  without any issue.
