Mitte Deutschland:. Anfang 11:12 Ende 13:10. Maximum 25% so rund 12:10 Such nice drawings you don't find in schoolbooks nowadays. Detail of celestial map showing the path of totality of the solar eclips of 12 May 1706 (Carel Allard)

Canon 700D attached to telescope: f=750 mm, f/5, ISO 200 and T=1/400 sec.

Note that after t=13:25 the time interval changes

In Oberlangen war es sonnig mit gelegentlich etwas hohe Bewölkung die aber nicht zuviel störte. Canon 700D attached to telescope: f=750 mm, f/5, ISO 200 and T=1/400 sec.

M81 and M82 are a well known interacting pair of galaxies Canon 700D attached to telescope: f=750 mm, f/5, ISO 3200, T=150x15 sec

Canon 700D attached to telescope: f=750 mm f/5, ISO 3200, T=100x15 sec. M97, the Owl Nebula, is a planetary nebula in "our" galaxy" at a distance of 1300 Lj. M108 (NGC3556) is a galaxy at 45 miljon Lj. and featured in my first scientific publication.

M 101 is a galaxy in the constellation Ursa Major (in which Alkaid is one of the brighter stars). The halo around the bright stars is due to lens errors. Left and middle a positive and negative display of whole field, taken with Canon 700D and Samyang lens: f=85 mm, f/2.0, ISO 1600, T=50x15 sec. Picture on the right taken with Canon 700D attached to telescope: f=750 mm, f/5, ISO=3200, T=50x15 sec.

Left and middle a positive and negative display of whole field, taken with Canon 700D and Samyang lens: f=85 mm, f/2.0, ISO 3200, T=50x15 sec. Picture on the right taken with Canon 700D attached to telescope: f=750 mm, f/5, ISO=3200, T=40x15 sec. Finally a nice clear sky and a possibility to find NGC 5907, an edge-on galaxy I studied ~40 years ago with the WSRT radiotelescope in the Netherlands

Canon 700D attached to telescope: f=750 mm, f/5, ISO=3200, T=100x15 sec. This galaxy in the constellation Ursa Major is at a distance of ~16 Miljon Ly., has a size of ~170.000 Ly and has a mass of ~100 billion solar masses. It is a bigger galaxy than our own Milkyway. On a picture like this you only see the bright spiral arms. Most of the mass you don't see here. It is like a picture taken from space of f.i. Germany at night, you only see the bigger cities.

Since a few month the Sun is active again but not very spectacular yet. Just to remind you of the partial solar eclips on june 10

Die gelbe Linien zeigen den Bedeckungsgrad und die rote Linien die Zeit der maximale Phase.. zB. in Hamburg ist die Bedeckungsgrad ~17% und ist das Maximum um ~12h34m, in Nürnberg ist es um 12h30m ~9% Vorsicht mit der Sonne, man braucht unbedingt eine Eklipsbrille und wenn man fotografieren möchte bastle euch einen Filter unter verwendung einer Eklipsbrille

A galxy belonging to the Local Group. Other members are the Milkyway and M31, the Andromeda nebula Canon 700D with Samyang f=85 mm, f/2,8, T=50x30 sec, ISO 1600, cropped

Alkahid is a bright star in Ursa Major Left: Samyang lens f=85 mm, f/2,0, ISO 1600, T=25x15 sec. Middle: same as left but negative to show details better Right: used telescope f=750 mm D=15 cm (i.e. f/5). T= 50x8 sec ISO 3200

picture on the right 5x1/50 sec. ISO 800 picture on the left 1x1/4 sec. ISO 800
