Letzte Nacht standen wir immer noch unter dem Einfluss des Sonnenwindes der auch die Polarlichter am Sonntag verursachte. Ich glaube ich bin schon etwas spät dran gewesen, trotzdem ist mir noch ein schönes Bild mit dem Roten Licht gelungen :)

Panorama aus vier Bildern

Endlich sind die Tage wieder kurz genug so dass die Nächte dunkel genug sind :)

Zudem war der Meteoritenschauer Delta Aquarids gerade auf seinem Höhepunkt.

Sechs Sternschnuppen gesehen und zwei "Zwilliungsschnuppen" konnte ich auch in dem Bild einfangen, die liegen genau Parallel zueinander :)

Wer von euch viele wünsche hat sollte am besten in der Nacht vom 11. auf den 12. oder auch noch möglich vom 12. auf den 13. zum Nachthimmel schauen, dann ist der Höhepunkt des Meteoritenschauers der Perseiden, der dieses Jahr besonders stark ausfällt. Schon mal viel Spaß beim Gucken :)

Beste grüße - Martin

Das Bild hab ich vor zwei Tagen Nachts um 01:30Uhr gemacht.

The M 101 Pinwheel Galaxy in LRGB with 2023 ixf supernova

M 101 is a very large, face-on spiral galaxy in the constellation Ursa Major, also known as the Pinwheel Galaxy.

M 101 was discovered by Pierre Mechain in 1781, and later the same year by Charles Messier.

M 101 has produced three supernovae in the 20th century: SN 1909A, 1951H, and SN 1970G, and now only a few days ago we can see supernova 2023 ixf in the NGC 5461 region.

Three nights of imaging in May 2023 from my home in Gérgal, Spain.

Da die Milchstraßenmitte jetzt endlich wieder zu sehen ist hab ich mal die Nacht durch gemacht und auf den Untergang des Mondes und den Aufgang der Milchstraßenmitte gewartet. Um fünf ging dann die Dämmerung wieder los und es hieß (endlich) ab nach hause.

At 2.73 million light-years away, the Triangulum Galaxy is considered part of our local group - and is the 3rd largest galaxy in the neighborhood. Although its area in the sky is roughly 4 full moons, its low surface brightness make is extremely difficult for unaided observation - requiring dark skies.

NGC 7635 Bubble Nebula

Distance from Earth: 11,090 light years

NGC 7635 (sometimes known as the Bubble Nebula or C 11) is a diffuse nebula visible in the constellation of Cassiopeia, towards the border with Cepheus.

It is a HII region, at the southern vertex of which there is an empty structure, caused by the pressure of the radiation of a central star of blue color (spectral class O), SAO 20575, of ninth magnitude, whose stellar wind reaches 2000 km / s; it is a blue Giant, which is also responsible for the ionization of the nebula, which emits its own light. Its distance from the Sun is estimated at 11,000 light-years.

Hallo liebe flickr Freunde, ich wollte mal Danke sagen für eure lieben, zahlreichen Kommentare und Favs, leider kann ich das zur Zeit nicht zurück geben da ich Arbeitstechnisch gerade einfach zu viel zu tun habe, dafür ein dickes Sorry, aber es wird in einem Monat wieder besser, ich versprechs :)

Liebe grüße - Martin

Hey flickr friends, i just wanted to say thank you, for your kind, copious comments and favs.

Unfortunately i cannot give it back to you cause i have just much to work and for that i wanted to say sorry!

But it will be better in about a month, i promise!

Lovely greetings - Martin :)

DeepSkyStacker + Lr - my first attempts to stack photos. Photo consisting of 21 photos with exposure parameters 12 mm, f / 2.8, ISO 3200, 5s - OBO tripod + Manfrotto XPRO 3W.

I have calculated that for an observer using a 12mm lens (MFT) and an eye resolution of max 1 "angle (this is for a person with great eyesight and for good eyesight it is 2" angular) - the maximum exposure time for getting the view of unmoving stars is about 4,33 s. Such photos without visible foreground can be snapped and then folded as panels with the foreground not moved into a mosaic.

I wanted to check if (O-MD E-M10 Mark II) M.Zuiko 12-40 mm f / 2.8 could work in the landscape field Astro (with the subject of the foreground on the ground) without a head with guidance (sky with stars as mosaic panels ) - please give me an opinion.

I am thinking of using Star Adventurer or iOptron Skyguider Pro, but since the results of star formation are punctual, does it make sense to use the head leading to the astro landscape with the subject of the foreground on earth?

The blurred glow at the bottom of the photo comes from slowly flowing clouds gently lit by the glare of lights from a city 20 km away (Opoczno).

C/2019 Y4 (Atlas) had lots of potential to become a naked eye comet during late May. However, as seen before, comets can be very unpredictable. Around mid-March, observations indicated its brightening has slowed, and by early April there was speculation it was breaking up. This was confirmed with a closeup image taken on 11-April-2020, the same day as the one I acquired above.

Although the above image was 1st aligned on the stars and then combined (DSS) with comet aligned images, it coma is diffuse and elongated.

The Pleiades taken this week during a surprise and brief period of dark skies and no clouds.

The Pleiades or Seven Sisters, catalogued as Messier 45, is an open star cluster of middle-aged hot blue B-class stars in the constellation Taurus, approximately 444 light years from Earth. The glowing blue nebulosity is thought to be an interstellar dust cloud, illuminated by the stars.

I didn't get to take many Milky Way shots last year.. 2 in total I think, so I'm looking forward to this season.

The landscape in the South Dakota Badlands has been compared to that of the Moon. So on this moonless night, it was easy to imagine that the Moon had fallen from the sky and was indeed beneath my feet.

I took 3 vertical images each for the sky and foreground. Sky images were tracked for 2 minutes each with the iOptron Pro at ISO 800. The foreground images were light painted with my flashlight and exposed for 2 minutes at ISO 2500.

Mit Blick nach Gager,. das ist mein erstes Milchstraßenbild mit der 70Da und ich bin ganz froh drüber :)

Ich hab bei dem Bild erst den Vordergrund mit 211Sek ISO800 aufgenommen und danach den Himmel mit 10x181Ssek bei ISO800 jeweils mit Blende 2.8. Kamera ist eine Canon 70Da, Nachgeführt mit dem iOptron Skytracker.

Comet 46P/Wirtanen

46P/Wirtanen is a 1.2 km Jupiter family comet with a 5.4 year period. It was discovered by Carl A. Wirtanen on January 17, 1948. Closest approach will occur on December, 16

Although a vivid tail is not visible, the comets coma is very large. Based on the above frame dimensions, the coma is larger than the full moon - approx. 0.6 degrees.
