NGC 6188 Rim Nebula

NGC 6188 is sometimes called The Fighting Dragons of Ara. As a fan of Game of Thrones or Hobit, I simply had to capture this beauty. Two dragons are clearly visible in the middle. Their heads are illuminated by the open cluster NGC 6193. I knew that this nebula is dim, so I dedicated a lot of time to it. Specifically, I stacked 86 narrow band pictures, each 5 minutes long.

NGC 6357 Lobster Nebula NGC 6334 Cat’s Paw Nebula

Both Lobster and Cat’s Pas nebulae are located in the constellation Scorpius, both are approximately 5’500 light-years from us. I tried to photograph the Lobster Nebula before, but it wasn’t an easy target due to very low southern declination. From the southern hemisphere, it is much easier. So I took the opportunity when I was in Namibia and tried to capture both nebulae in one shot.

The composition of this picture was not correctly selected, but in the end, both are in the field of view. Here is the picture processed in the “fake” Hubble palette:

And here is the bi-color version (R-Ha, G-OIII, B-OIII)

Vela Supernova Remnant

Supernova Remnant in the southern constellation Vela is the closest remnant to Earth. It is “only” 800 light years away from us and it has a diameter of 100 light years. This is the reason why this deep space object didn’t fit in the field of view of my portable 250 mm focal length RedCat. The initial plan was to make a panorama of two pictures, but I failed to make an overlap, so I present two separate pictures. At least I have one more reason to come back to Namibia ,’-)

IC 2602 Southern Pleiades

Southern Pleiades, just like the northern Pleiades is an open cluster, located in the constellation Carina. Unlike the northern sibling, this cluster is not associated with nebulosity. However, some dark nebulae can be found around. This is because the cluster is located just a few degrees from the galactical equator.

Norma Star Cloud

The constellation Norma is surrounded by the constellations Scorpius, Ara, Lupus, and Triangulum Australe. It forms the Milky Way’s Norma arm. Therefore there are a lot of stars anywhere you look. I wanted to capture something other than the nebulae, galaxies, or clusters. And this is exactly what I managed. This star cloud is not visible even from southern Europe, so I included it in the capture plan for my trip to Namibia.

In order to resolve the stars properly and fit the whole start cloud in the field of view, I used RedCat 51 telescope, having a focal length of 250 mm.
