  1. DeHt5 (Dengel-Hartl 5) is a large faint ancient planetary nebula in the constellation Cepheus. It is estimated to be one of the closest planetary nebulae at a distance of 1300-1600 light years. The faint red filaments at the top right hand corner of the image are the supernova remnant called SNR 110.3+11.3. Astrodon Blue: 19x300" Astrodon Green: 19x300" Astrodon Lum: 20x600" Astrodon Red: 20x300" Astrodon Ha: 25x1800s bin 2x2 Astrodon OIII: 26x1800s bin 2x2 Total Integration: 34 hours Captured on my dual rig in Spain. Scopes: APM TMB LZOS 152 Cameras: QSI6120wsg8 Mount: 10Micron GM2000 HPS
  2. MWP1 (Motch-Werner-Pakull 1) also known as The Methuselah Nebula is a rarely-imaged faint bi-polar planetary nebula in the constellation of Cygnus. It is one of the largest known planetary nebulae - spanning some 15 light years. It lies around 4,500 light years from Earth. Astrodon Blue: 16x300" Astrodon Green: 16x300" Astrodon Lum: 18x600" Astrodon Red: 16x300" Astrodon Ha: 35x1800s bin 2x2 Astrodon OIII: 37x1800s bin 2x2 Total Integration: 43 hours Captured on my dual rig in Spain. Scopes: APM TMB LZOS 152 Cameras: QSI6120wsg8 Mount: 10Micron GM2000 HPS
  3. Another great image Olly. What’s the thinking behind 9 hours of colour and 7 of luminance? I always thought the most of the capture should be luminance to tease out most detail? Peter
  4. Thanks Geordie. This is a tough one with dark skies. Getting those shells in poor skies will be really tricky.
  5. An unusual group of galaxies i(ARP 227) in the constellation of Pisces. Outer shells may have been created from gravitational interaction between galaxies. The largest galaxy is NGC 474. It is 100 million light years away, and about 250,000 light years across. The outer shells are extremely faint and have necessitated 1800s luminance exposures. Astrodon Blue: 63x300" bin 2x2 Astrodon Green: 64x300" bin 2x2 Astrodon Lum: 54x1800" bin 1x1 Astrodon Red: 54x300" bin 2x2 Total Integration: 42.1 hours Captured on my dual rig in Spain. Scopes: APM TMB LZOS 152 Cameras: QSI6120wsg8 Mount: 10Micron GM2000 HPS
  6. Sharpless 200, also known as HDW 2 (Hartl-Dengl-Weinberger 2) and commonly known as the Bearclaw Nebula is a very faint planetary nebula in the constellation of Cassiopeia. The Ha signal is much fainter than the OIII so I went extra deep on the Ha capture. Astrodon Blue: 20x300" bin 1x1 Astrodon Green: 10x300" and 10x600" bin 1x1 Astrodon Lum: 37x600" bin 1x1 Astrodon Red: 20x300" bin 1x1 Astrodon Ha 5nm 62x1800" bin 1x1 Astrodon OIII 3nm 37x1800" bin 1x1 Total Integration: 61.5 hours Captured on my dual rig in Spain. Scopes: APM TMB LZOS 152 Cameras: QSI6120wsg8 Mount: 10Micron GM2000 HPS
  7. An excellent image of a target so often overshadowed by its big neighbour. Well done. That long integration has really paid off.
  8. Yes Alan, its been a remarkable run of clear weather.
  9. A barred-spiral galaxy in the constellation of Camelopardis. It is estimated to be 112 million light years away. Astrodon Blue: 14x300" bin 1x1 Astrodon Green: 30x300" bin 1x1 Astrodon Lum: 92x600" bin 1x1 Astrodon Red: 30x300" bin 1x1 Total Integration: 21.5 hours Captured on my dual rig in Spain. Scopes: APM TMB 152 LZOS refractors Mount: 10Micron GM2000 HPS Cameras: QSI6120wsg8
  10. There is a tiny amount of featureless O3 - but it is so little it wasn't worth including it.
  11. A planetary nebula in Cassiopeia discovered by Marcel Drechsler in May of this year. Intensely faint. 25 hours of HaLRGB Captured on my dual rig in Spain. Scopes: APM TMB LZOS 152 Cameras: QSI6120wsg8 Mount: 10Micron GM2000 HPS
  12. A very faint planetary nebula in the constellation of Cassiopeia. It was identifed by Laurent Ferrero in November 2013. This is a total of 41 hours of integration. HaOIIILRGB Captured on my dual rig in Spain. Scopes: APM TMB LZOS 152 Cameras: QSI6120wsg8 Mount: 10Micron GM2000 HPS
