  1. Last week I had several clear nights with accepteable transparency. So I continued my galaxie album with M 94 and NGC 4631 - both located in the constallation of Canes Venatici. First M94: Details and some background information: http://www.spaceimages.de/en/astrophotos/galaxies/m-94 or: https://www.astrobin.com/398461/E/ Second NGC 4631 (The whale): Details and background: http://www.spaceimages.de/en/astrophotos/galaxies/ngc-4631 or: https://www.astrobin.com/398918/D/ I hope you like the images. Cheers Jens
  2. Very nice field. I like this group very much. You did a great job with details and colors. If critisism is allowed, some stars are too blue in my eyes. Cheers Jens
  3. After a while I like to present my latest image of NGC 4449. It is an irregular galaxy of the Large Magellanic Cloud type, also called LMC type, in the constellation of Canes Venatici. It has an angular extension of 5.5' × 3.6' and an apparent brightness of 9.4 mag. At the end of February we had a lot of nice days, but the nights were filled with cirrus and dust. So why not take up a very weak irregular galaxy, the mentally deranged astrophotographer is thinking. In retrospect I felt like this after 4 nights. Then I took it as a challenge and could work out a decent picture at the end. What you see here are about 13 hours of HaLRGB (with CLS filter as luminance) and 20 hours of processing to get rid of the gradients and the dust in my raw material. At least: with a lot of good will you can see the tidal tail left above the galaxy. Data and more information: http://www.spaceimages.de/en/astrophotos/galaxies/ngc-4449 or https://www.astrobin.com/392780/ If someone is at the CEDIC in Linz (Austria) 15th - 17th of march, you can meet me there. I'm looking forward to it. Cheers Jens
  4. A warm thank you to all commenters. I am glad that you like the image. ?
  5. Hello everybody, the requested M31 mosaic is ready Details: http://www.spaceimages.de/en/astrophotos/galaxies/m-31-mosaic or https://www.astrobin.com/378147/ Best viewed in full resolution. I hoppe you like it. Jens
  6. Hi, I used to be in the mood for M31. Since my Newton doesn't quite get it completely on my camera chip (ASI 1600 MMC), I concentrated on the "northern" part (at least in the usual way). After two somewhat hazy nights in which I collected 5.5 hours of LRGB in my backyard observatory, the following was the result: (and YES - I will go for a mosaic :-)) bigger and data: http://www.spaceimag...es/m-31-of-2018 or https://www.astrobin.com/376031/ Cheers Jens
  7. Never seen a more three dimensional Andromeda galaxy before. Stunning... Jens
  8. Hello, Sh2-150 is a fairly extensive H II region oriented north-south east of 26 Cephei. It is located at a distance of about 900 parsecs (over 2,900 light years), next to the nearby Sh2-145 nebula, and appears in the direction of the stellar associations Cepheus OB2 and Cepheus OB3 and may be associated with the expanding superbubble "Cepheus Bubble". Two blue stars would be responsible for its ionization: HD 213087 has the spectral class B0.5Ib and is therefore a blue supergiant, while HD 213405 of the class B0.5V is a main sequence star. Sh2-150 is so weak that it takes a lot of exposure time to capture a good clean image of the region. I exposed a lot in pure RGB, because there are some nice reflection nebulae in the area I wanted to show. Camera was an ASI 1600 MMC. Details: http://www.spaceimages.de/en/astrophotos/nebula/sh2-150 or https://www.astrobin.com/371753/ Since I exposed with my two telescopes at the same time, I took another picture with the Epsilon 130 in a larger field, which otherwise has the same exposure data. Camera here was an Atik 490 Exm. Cheers Jens
  9. Thank you for your nice comments. I‘m glad you like the image.
  10. Mornin', finished another picture. It shows a section of Pickering's triangle. This celestial object was discovered in 1904 by Williamina Fleming. It was commissioned by Edward Charles Pickering, director of the Harvard College Observatory, to examine photographic plates and catalog the stars and other celestial bodies. As was usual at the time, newly discovered objects were named after the employer and not after the assistant of the observatory who made the discovery. Williamina Fleming made many discoveries during her work for Edward Pickering. One of the most famous objects she discovered is the Horsehead Nebula. The picture was worked out as HaOIIIRGB. Besides the narrowband data, which clearly show the structures, there are also many hours of RGB in the image, which give the whole thing the beautiful colours. More data and larger view here: http://www.spaceimages.de/en/astrophotos/nebula/ngc-6979 or https://www.astrobin.com/364407/ Many greetings Jens
  11. Like Rodd wrote, I used method 2. The result was better than every single stack. The 15s exposures where only a test because of the new camera. As I did not see any advantage, I will not do it again.
  12. End of may I captured M 101 during three nights with my 10" inch newt and the ASI 1600 MMC. Here is the final result right before summer break. data and more: http://www.spaceimages.de/en/astrophotos/galaxies/m101-galaxie-detail or https://www.astrobin.com/347019/ Greeting Jens
  13. Thanks for all nice comments. Marcel not only flipped his image, he streched the luminance more than me. Something to make a difference between our both images. ?
