Jupiter at opposition

Jupiter is at opposition on May 8 & 9 and is the entire night visible.

Saturn in the morning sky

This morning I made some time to take pictures of Saturn. Conditions however are poor, with bad seeing and the ringed planet only showing up 16° above the south-east horizon. I was not able to observe details neither the Cassini division.
Pictures are taken with ASI224MC camera and stacking was done using AutoStakkert. Editing with CS4.

Napoleon's Hat, Picot 1

In the constellation Bootes, an asterisms named Napoleon's Hat or Picot 1 is visible.
It's a group of 7 stars, south of Arcturus, discovered by Fulbert Picot.

Jupiter and Great Red Spot

Jupiter.almost at opposition. Conditions were very well with good seeing and dark sky. The passing of the GRS (Great Red Spot) at the center was at 23h53UT and the picture was taken one hour later. You see the GRS clearly aswell the other cloudbands.
I used my TAL200K scope with ASI224MC camera. Stacking completed using AutoStakkert and final editing with CS4.

Succesfull ATT number 34

Again a very well organised ATT Astronomy Exhibtion in Essen Germany. A lot of people did visit the exhibition but it never felt overloaded.

Big players like Lunt, Bresser, Baader Planetarium, Astromarket, Teleskop-service, Vixen, Atik, Noctutet, ... gave their best to promote the astronomy equipment. But also private people gave their best in selling second hand stuff.

Lunt promoted their solarscopes by installing three H alfa scope for viewing at the sun.

My focus was on color filters, wide field oculars, solarscopes, small guided mounts and of course finding out the things I still don't know :)

During the day, ATT provided different lectures, of one on Solareruption I attended. See summary at this link.

Lecture by Ulrich von Kusserow at ATT Essen

I attended a great lecture at the Astronomy Exhibition ATT in Essen (Germany). The lecture was provided by Ulrich von Kusserow, Astrophysicist and specialized in Solarphysics.
The topic was about solareruptions, comets and polarlight.

The first part of the lecture gave a brief but very good overview on the current understanding how the sun works and making links to the influence with comets and polarlight. The second part provided a lot of pictures and movies about all the explained phenomena.

Part of the presentation can be downloaded via this link.
