21P/Giacobini-Zinner 2018-08-19

19.08.2018 / 22:22-22:59 UTC

21P/Giacobini-Zinner

Nachdem sich der Mond verabschiedet hatte und die letzten Zirren abgezogen waren, konnte ich noch einmal eine brauchbare Aufnahmeserie gewinnen.

Bei der Vorbereitung war mir aufgefallen, dass die Eigenbewegung des Kometen weiter zugenommen hat. Ich musste daher die Belichtungszeit auf 69s begrenzen, damit keine Bewegungsunschärfe des Kometen auftrat. Die Helligkeit hat gegenüber den letzten Tagen zugenommen.

29x69s; Takahashi FSQ-106ED (f/5) und Canon EOS 450Da (ISO800). Bildbearbeitung mit Astroart und Photoshop.

Durchziehende Wolkenfelder erschwerten die Aufnahmeserie.

Total Lunar Eclipse 2018-07-27 27.07.2018 / 23:10 CEST

Totale Mondfinsternis

Meine erste Astro-Aufnahme nach zwei Jahren.

Schwierige Bedingungen zu Beginn der Mondfinsternis mit einer großen Wolke direkt vor dem Mond. Ich konnte daher leider erst recht spät mit den Aufnahmen beginnen.

Hier ein Bild von meinem Beobachtungsplatz.

Testaufnahme eines ehemaligen Klosters, etwa 4 km entfernt.

Takahashi FSQ-106 ED (f/5); Canon EOS 450 Da. 1" Belichtung bei ISO 800.


The Transit of Mercury on May 9, 2016 at 13:51 UTC 09.05.2016 / 13:51 UTC

Merkurtransit

Schwierige Bedingungen mit z.T. starken Windböen. Gegen Ende des Transits kamen hohe Wolken auf und das Seeing wurde immer schlechter, allerdings konnte ich etwa 2/3 des Ereignisses aufnehmen.

Bei diesem Bild handelt es sich um eine Montage von 5 Summenbildern.

Note the rising Great Red Spot

Seeing was ok at the beginning of the observations, but got worse in the further course.

One month after opposition, Jupiter's apparent diameter is shrinking, note oval BA in the southern region.

Poor seeing with some strong gusts of wind.

Callisto is casting a nice shadow on Jupiter's atmosphere. Unfortunately, Callisto was slightly out of "ROI" in the second image. Good seeing this night.

Jupiter with GRS

My first Jupiter image since a long time.

Great Red Spot with intensive colors.

Seeing was very turbulent this evening, very difficult conditions.


M13: Globular Cluster in Hercules 07.06.2015

Globular Cluster M13 in Hercules

This is a first light image with my new Takahashi FSQ-106ED. The conditions were not optimal (high clouds, bright background sky, low wind) and I only managed to take 6x300s sub-exposures + 6 dark frames.

Takahashi FSQ-106ED at f/5, Canon EOS 450Da (modified).


The Great Orion Nebula Feb. 16, 2015 16.02.2015

The Great Orion Nebula

I was testing autoguiding with a ZWO ASI120MM this evening - worked pretty well!

12x300 s exposures + 13 dark frames were taken.

Takahashi FS-102N at f/6, Canon EOS 450D (unmodified).


The Sun on Feb. 7, 2015 07.02.2015 / 09:05-09:32 UT

The Sun In Visible White Light

My very first image of the sun - many sunspots are visible.

This is a white light image, with my new Baader AstroSolar ND 5.0 filter.

TMB-LOMO 80/600, Canon EOS 450D, 76 single frames were stacked.


Mars on March 29, 2014 at 23:26.3 UT 29.03.2014 / 23:26.3 UT

Mars

My first Mars image of this season. The bright spot near the center can be identified as Olympus Mons, to the east the Tharsis volcanoes can be seen (covered with clouds). On the western limb, Elysium appears in the morning haze.

This is my first image with my new Baader RGB filters.


Moon on March 12, 2014 12.03.2014 / 19:30 UT

The Moon

Jupiter, Great Red Spot, Io and Shadow

Beautiful view this evening. Jupiter's moon Io can be seen to the left side above the Great Red Spot, casting a beautiful shadow on Jupiter's atmosphere.

07.04.2013

Comet C/2011 L4 (PANSTARRS)

A new attempt of capturing a detailed image of the comet.

I employed my Takahashi FS-102 with the Takahashi focal reducer (f/6) and took 54 images, each 40 sec. at ISO 800 (so total exposure is 36 min.). I also took 33 dark frames.

The final image is a dark corrected stack, centered to the comets nucleus. Image processing was conducted with Fitswork and Photoshop.

Below, I added a picture of my setup at the imaging site.


C2011 L4 (PANSTARRS) April 1, 2013 01.04.2013

Comet C/2011 L4 (PANSTARRS)

This time I've used my TMB 80/600 APO to capture the comet. Unfortunately, I could only take 6 frames until clouds rolled in. It was difficult to image the comet due to its low altitude.

Canon EOS 450D with TMB 80/600 APO. 6 x 25 s at ISO 800.


C2011 L4 (PANSTARRS) March 14, 2013 14.03.2013 / 18:32 UT

Comet C/2011 L4 (PANSTARRS) in the Dusk

This comet is now a relatively bright object of the evening-sky. Binoculars are needed for detection.

Canon EOS 450D with 50 mm EF-S objective, 6s integration time at ISO 800.

Excellent seeing this evening! Note the many swirls around the GRS and the reddish storm system in the northern polar region.

Jupiter with GRS and Oval BA

Terrible conditions this night. After setting up my equipment, suddenly clouds came in and it started snowing! But my equipment was safely stored in plastic bags so nothing was damaged. Seeing also was very unstable bud I was able to shoot some images with reasonable detail.

The image on the left side has been derotated with WinJUPOS.

Complex rift system on the NEB.


Saturn May 25, 2012 at 21:06 UT 25.05.2012 / 21:06 UT

Saturn

The low altitude of just 31° makes Saturn a difficult object to observe. The bright storm system of the northern hemisphere that appeared in 2011 has emerged into a bright belt. Note also the shadow of the ring system on Saturn's atmosphere.

This is a first light image with my new RGB-Filters (Astrodon I-Series).


Mars 23.03.2012 23.03.2012 / 19:19 UT

Mars

Chryse Planitia, Terra Meridiani Arabia Terra are dominating this sight of Mars. Note Syrtis Major on the planets limb and some morning haze over Tharsis.


Mars 22.03.2012 22.03.2012 / 20:00 UT

Mars

Better seeing conditions this evening. Chryse Planitia, Terra Meridiani and Arabia Terra visible, morning haze over Tharsis. Note the dark edge of the northern polar cap.


Mars 15.03.2012 15.03.2012 / 21:39 UT

Mars

Tharsis region. The bright spot in the center of the planet can be identified as orograpic clouds on the lee-side of Ascraeus Mons. Seeing conditions were very unstable this evening.

This is my first light image with my new DMK 21AU618.AS and Baader FFC.
