The Tadpole Nebula, Sh2-236, in an plain H-alpha image. You can easily find the two tadpoles that give rise to the name. It belongs to one big emission complex together with the Flaming Star Nebula. Composed of a total of over 5 hours of 10 min exposures from my backyard. See also the bicolor version. […]
A plain H-alpha image of the central region of Sharpless 171 (Sh2-171). This busy region is surrounded by another ring of gas, not visible in this frame. Composed of a total of 4.5 hours of 10 min exposures from my backyard. A first test of the 0.79 Reducer from TS… stars are looking good already. […]
The California Nebula in a two-panel LRGB mosaic using a total of 24 hours of data taken at the Deep Sky West Observatory. Exposure: LRGB, 2 x (24,16,16,16) x 600sec Date: 2016-10-01…2016-11-03 Setup: Takahashi FSQ106 EDXIII with QSI 683WSG-8 Site: Deep Sky West Observatory, NM, USA
This sinister scenery shows LDN 1495 and the blue reflection nebula LBN 782. It looks like the head of a dragon with a hazy blue eye… This is an LRGB composite using 25+16+16+15 individual LRGB exposure of 900 sec. taken at the Deep Sky West Observatory. Exposure: LRGB, (25,16,16,15) x 900sec Date: 2016-11-30…2016-12-26 Setup: Takahashi […]
The neighborhood of the Iris Nebula in Cepheus holds more secrets. This arrow-shaped complex is LBN 468 with lots of swirling bright and dark nebulosity. A very interesting and small structure, resembling a tiny comet, can be found at the tip of the arrow. This is the Herbig-Haro object known as HH 215 or Gyulbudaghian’s […]
The central section of the Heart Nebula (IC1805) with the open cluster Melotte 15. The stellar wind and radiation from this cluster of massive host stars, about 1.5 million years young, has sculputured the emission nebula and dark dust clouds into a dramatic scenery. One more quick mono Ha image of a well known object […]
The Flaming Star Nebula in a simple Ha narrowband image. Composed of a total of 4 hours of data taken from my balcony in the light-polluted Frankfurt area – Bortle class 7 (red zone). Exposure: H, 24 x 600sec Date: 2016-12-04 Setup: APM 107/700 Triplet APO with ATIK 460 EXm Site: Langen, Hessen, Germany
This is the official first-light image with my new APM 107/700 Triplet APO! It works beautifully with the Hotech SCA Field Flattener and the ATIK 460EXm and produces a nice flat field – much better than my previous setup. This combo will be my high-resolution combo for quite some time. As you will have guessed […]
The Rosette Nebula, a stunning emission nebula at the edge of a large molecular cloud in Monoceros, some 5000 light years away. Its flowery appearance is sculpted by the winds and radiation from its central cluster of hot young stars. This is a narrowband composite from (16,16,20) x 1800 sec exposures in Ha, OIII, and […]
The complete Cygnus Loop or Veil Complex in a bicolor narrowband rendering. Recently, I posted a version of the same object taken during my summer vacation in the Mediterranean. I liked it, but was not perfectly happy with the raw data and the processing. So, back home I decided to do it again from scratch, […]
