Starclusters in Gemini (view on black)
| |
|
|
|
Die Linien verbinden die Sterne die den Fuss von Castor, einer der Zwilinge, bilden. M35, N 2158 und N 2129 sind offene Sternhaufen (wie die Plejaden) und N 2175 ist ein Sternhaufen mit schwacher Nebel.
Eine Einzelbelichtung (Ausschnitt) mit f=85 mm, f/2,8, T=15 sec, ISO 800 und Nachführung. Die Darstellung als Negativ zeigt Details und schwache Objekte besser
Centre of Orionnebula

|
|
|
Just a single exposure to test the Barlow lens. Canon in prime focus of Newtontelescope, D=15 cm f= 750 mm. Barlow lens is used to double the focallength.
The galaxies M95 and M96
| |
|
|
|
Two spiral galaxies of the Leo group. Combined 20 exposures
The PiP shows three other galaxies of the Leo group
M101, die Feuerradgalaxie
| |
|
|
|
Combined 60 exposures with T=30s, ISO3200 and Canon 700D in prime focus of reflector with f=750 mm and D=15 cm
M101
| |
|
|
|
A nice spiral galaxy we see "face-on" in the constellation Ursa Major. For this picture I used 9 exposures
Plejades with Merope nebula (view on black)
| |
|
|
|
combined 50 exposures with a Canon 700D. Each exposure T=30 sec, f/4, f=200 mm and ISO=1600
An Orion triptychon
| |
|
|
|
Two sets of exposures, one centered on the Horsehead nebula (left) and one on the Orion nebula (right). Both sets are a combination of 50 exposures with a Canon 700D, f=200 mm, f/4,0, T=30 sec and ISO 1600. Tracking was done by a Newton reflector.
The picture in the middle is a combination of the two sets and shows the correct geometry. The two brightest stars belong to the belt of Orion.
M42: Orion nebula (view on black)
| |
|
|
|
Combined 20 exposures. See Exif's. Used a Newton reflector with f=750 mm and D=15 cm and the camera in prime focus. Because of the moon, no ideal conditions
Constellation Cancer with Beehive cluster
| |
|
|
|
The least expresive zodiacal starconstellation Cancer with the nice open starcluster M 44, the Beehive cluster. M67 is another open star cluster.
Combined 10 exposures
M51: The Whirlpool galaxy
| |
|
|
|
Reprocessed exposures, colour version
Canon 700 D in prime focus of telescope (f=750 mm, D=15 cm)
Combined 19 exposures, each T=15 sec, ISO 3200
M51 and companion
| |
|
|
|
clear sky, no moon, time for galaxies
Canon 700 D in prime focus of telescope (f=750 mm, D=15 cm
Combined 19 exposures, each T=15 sec, ISO 3200
Leo triple
| |
|
|
|
Three galaxies (1000000000 stars each) in a field with a size of the full moon
Canon 700D in prime focus of telescope (f=75 cm, D=15 cm) ISO 3200 40X30 seconds exposure
M1 Crabnebula
| |
|
|
|
combined 40 exposures
The remnant of an exploded star (a supernovaremnant). This explosion was recorded In China in 1054 AC. It is the home of the first discoverd pulsar, a fast rotating neutron star.
Orionnebel (view on black)
| |
|
|
|
Vorige Woche endlich mal wieder zwei superklare Nächte. Konnte den Orionnebel trotz kälte, nicht widerstehen, also nochmals ein Bild vom Orionnebel, vielleicht das bis jetzt beste.
50 Aufnamen je 10 sekunden mit ISO 1600, f=750, D=15 cm
M35
| |
|
|
An open starcluster in the constellation Gemini. Already good visible in a binocular
f-750 mm, ISO1600, T=50 x 15 seconds
Die Plejaden

|
|
Orion nebula (view on black)
M1, the Crabnebula
| |
|
|
|
In between clouds I got 10 usefull exposures of this supernova remnant, the remnants of a star that exploded in 1054 AC. This explosion has been observed by chinese astronomers
