The Sadr region, IC 1318, is the busy neighborhood round the mag 2.2 star Sadr or gamma Cygni. It is a large expanse of nebulosity with dominant Ha emission nebulae and various dark nebulae. The Crescent Nebula (in the lower left corner of the image) is embedded into the region. This is a simple Ha […]
Now the full three-color narrowband version of the North America and Pelican Complex, following my earlier Ha monochrome version. Both nebulae belong to the same interstellar cloud of ionized hydrogen gas, but they are separated by a ragged lane of interstellar dust that absorbs their light. The North America (NGC7000) and the Pelican Nebula (IC5070) […]
This is the second target for my new wide-field setup, the North America and Pelican Complex. Both belong to the same interstellar cloud of ionized hydrogen gas, but they are separated by a ragged lane of interstellar dust that absorbs their light. The North America (NGC7000) and the Pelican Nebula (IC5070) show a rich and […]
Now the three-color version of the Cygnus Loop in Ha, OIII and SII using 24 x 300 sec exposures for each channel, i.e. a total of 6 hours. Taken with the ATIK 460EXm camera in combination with my Asahi/Pentax Takumar 135mm f2.5 photo lens. Exposure: HOS, (24,24,24) x 300sec Date: 2016-7-17…2016-7-18 Setup: Takumar 135mm f2.5 […]
This is the first-light image with my new wide-field travel setup. I decided to try the ATIK 460EXm camera in combination with some old M42 photo lens, in this case with the Asahi/Pentax Super-Multi-Coated Takumar 135mm f2.5, a wonderful super-solid 6-element tele-lens from 1972 (my age). This combination gives a field of view of more […]
The Crescent Nebula, NGC 6888, in a wide-field setting with lots of surrounding nebulosity. This is a pure narrow-band composite based on (18,16,15) frames for Ha, OIII, and SII with 1800sec each, taken at the Deep Sky West Observatory. The different versions below represent different color mappings, otherwise the processing is pretty basic. Exposure: HOS, […]
The Whirlpool Galaxy, M51, in a wide-field setting. This is an LRGB composite with a little bit of Ha admixture from a total of 22 hours of exposures taken at the Deep Sky West Observatory. Exposure: L 32 x 900sec, RGB (16,16,16) x 600sec, Ha 16 x 1800sec Date: 2016-04-10…2016-05-04 Setup: Takahashi FSQ106 EDXIII with […]
The Leo Triplet, a well known trio of beautiful galaxies – M65, M66 and NGC3828. Actually, there are many more tiny galaxies in this image. All of them belong to the M66 galaxy group with the Leo Triplet at its heart. In this deep exposure you also see the tidal tail extending from the edge […]
The Whale and Crowbar Galaxies, NGC4632 and NGC4656, in an LRGB composite. A pair of interesting galaxies in Canes Venatici, which might have had a close encounter in the past. The Whale Galaxy is an edge-on spiral galaxy with a slightly distorted silhouette, its about the same size as our Milky Way. The Crowbar or […]
This is the Pinwheel Galaxy, M101, in a wide-ish field LRGB composite. Usually one would image this beauty at a slightly larger focal length, but this wider field puts the galaxy into a nice context. M101 is a large galaxy, quite comparable to the Milky Way. With a diameter of 170,000 light-years it is about […]
This is a HaLRGB composite of M106 with its companion NGC4217 and many small neighbours. Have a look at the full-size image to discover all the tiny galaxies in this field. The image is composed of 25 x 900 sec luminance, 16 x 600 sec RGB, and 19×1800 sec Ha exposures taken at the Deep […]
