Sh2-200 (HOO)
Sharpless 200, also cataloged as LBN 674 is a small nebula in Cassiopeia. Measuring only 8 arc minutes across it doesn’t take up a log of sky. It’s also very […]
Astronomical League 2022 Calendar
The Astronomical League is a great organization that promotes astronomy and if you belong to a local astronomy club the odds are that you may be a member. For 2022 […]
Ghost Nebula (LRGB)
October seems to be the month for ghostly nebula. This time it’s a dust blob in the vague shape of a ghost with a little mini ghost up above. It’s […]
The Ghost of Cassiopeia (HSO)
The Ghost of Cassiopeia, IC 63 and IC 59, is an emission nebula in, not surprisingly, Cassiopeia. This is a fairly faint nebula and has the unfortunate fate of being […]
Elephant Trunk Closeup (modified SHO)
The Elephant Trunk Nebula is a very large nebula though the “trunk” itself occupies only a small part of that. This telescope’s field of view was perfect for doing a […]
Lion Nebula (SHO)
I reprocessed the Lion with the tone map technique and it’s converting me to be a fan of SHO. Unlike the original version that was a modified SHO, this is […]
NGC 7129 (HaLRGB)
There’s a lot going on in this section of the galaxy: reflection nebula, dust, hydrogen alpha emission although the NGC 7219 designation refers just to the reflection nebula. That reflection […]
Barnard 352 (HaRGB)
Barnard 352 is a dark nebula in Cygnus but that means there’s also lots of hydrogen around for that red background. Barnard 353 is that smaller dark patch just above […]
Wizard Nebula (SHO)
The image above is a reprocessing of the same data shown below. This is an unmodified SHO palette while the one below does tweak the colors somewhat. The major difference […]
Iris Nebula (LRGB)
The Iris Nebula is a reflection nebula surrounded by dust making for one of the more unique nebulae in the night sky. At a distance of about 1,300 light years, […]
Tulip Nebula (HOS)
The image above is a reprocessing of the data below. It’s still an HSO palette. This is a tone map process where the color, luminance and stars are all processed […]
Fireworks Galaxy (HaLRGB)
The Fireworks Galaxy, NGC 6949, gets its name because ten supernovae have been observed there in the last 100 years. That is a rate far in excess of what most […]
LDN 673 (LRGB)
LDN 673 is one of many dark nebula in the Milky Way. It it caused by dust blocking the light creating these abstract dark patterns through the dense star fields. […]
M16 (SHO)
M16, the Eagle Nebula doesn’t really need an introduction. The Hubble Space Telescope image of the “Pillars of Creation” captured the collective imagination when it was first shown to the […]
Crescent Nebula (HOO)
I’ve learned some new techniques and I reprocessed the data collected earlier. The result is more detail and a more vibrant image. The image below was the earlier processing attempt […]
Bubble Nebula (HSO)
This is another tone mapping reprocess of older data. This one also involved a palette change. The blues and purples in the original version tended toward this super hot pink […]
