NGC6744 Galaxy in LRGB

Recommended Posts

I loved processing this amazing galaxy photo. The photos taken during my Namibia travel this year. It was taken during 2 nights.

Photo Details:
Lum: 18x10Min=3Hours
RGB: 8x3Min=24Min for each RGB channel

Telescope: ASA 12'' Astrograph F3.6
Mount: ASA DDM85
Camera: FLI 8300 Mono

One of the best astrophotos I've seen posted on this forum - really well done!

      Hi! I've recently acquired a new Astromodified Canon rebel XT and I've tried to take pictures of nebulas using it but I've noticed that there are these weird black artifacts that keep appearing in my images. Would like to know if anyone has experienced this before? Or are these dirt/dust specs on the camera, filter, and telescope glass? I've attached some of my edited and raw pictures for your reference. The black artifacts can already be seen in the raw image of the horsehead nebula and after stacking I think it got amplified. Anyway, advance thanks and I hope everyone's doing well.

      The galaxy group Hickson 44 in Leo. This is based on 29 x 240 s, plus bias and flats.

      Hickson 44 in Leo:

      There are some other galaxies near by, some of which are names in this overlay from Astrometry.net:

      Overlay from Astrometry, naming the other objects:

      The main ones are NGC 3190, NGC 3185, NGC 3187 and NGC 3193. NGC 3190 has a well defined dust lane. NGC 3187 is a barred spiral galaxy with two arms. NGC 3193 is an elliptical galaxy.
      The light captured by my camera last night left these galaxies just after the extinction event killed the dinosaurs on Earth.
      From APOD: Galaxies, like stars, frequently form groups. A group of galaxies is a system containing more than two galaxies but less than the tens or hundreds typically found in a cluster of galaxies. A most notable example is the Local Group of Galaxies, which houses over 30 galaxies including our Milky Way, Andromeda, and the Magellanic Clouds. Pictured above is nearby compact group Hickson 44. This group is located about 60 million light-years away toward the constellation of Leo. Also known as the NGC 3190 Group, Hickson 44 contains several bright spiral galaxies and one bright elliptical galaxy on the upper right. The bright source on the upper left is a foreground star. Many galaxies in Hickson 44 and other compact groups are either slowly merging or gravitationally pulling each other apart.
       
       
      Abell 1367
      This image is based on 19 x 300 s , plus flats and bias. It shows a LOT of galaxies, in a grouping called Abell 1367. In this image you are looking at part of one of the biggest structures in the Universe, the Great Wall.

      Wikipedia:
      The Leo Cluster (Abell 1367) is a galaxy cluster about 330 million light-years distant (z = 0.022) in the constellation Leo, with at least 70 major galaxies. The galaxy known as NGC 3842 is the brightest member of this cluster. Along with the Coma Cluster, it is one of the two major clusters comprising the Coma Supercluster, which in turn is part of the CfA2 Great Wall, which is hundreds of millions light years long and is one of the largest known structures in the universe.
      The overlay from Astrometry gives some of the galaxies visible in the image.

      To celebrate the 25th anniversary of Sir Patrick's DSO catalogue, I've added the available Caldwells to my basic Marathon search sequence. 
      Those interested may be pleasantly surprised by how many of the additional treasures are only a short hop from a given (or en route to the next) Messier.
      The sequence for 40°N can be found at the SEDS Messier Marathon homepage or at my blog.
      Peace, Stephen

      So, although I had some issues with my auto guiding (which I found out afterwards) I did manage to get 9x180s exposures and 5 darks of Andromeda and give both stacking (using DSS) and processing (using GIMP).
      My first attempted DSO....
       
      I am pretty sure that people could get far more information out of the TIFF file from the stack.
      Hopefully I will get another clear night soon. I am in a heavily light polluted area so I do have a clip in filter on my DSLR which I think took a lot away.
      More practise needed!

      So I picked up a classic... a 1970's - 80's edmund optics f6 150mm newtonian...

      ... like this one but mine has a different mount. It was cheap. Very good condition. The focuser is pants. The mechanics of the secondary holder is (IMHO) brilliant and apparently the primary is 1/10th wave.
      But its f6 and I trhink I'd rather swap it out for a faster synta f5 mirror. .  The thing is its a one shot job bc to make the f5 mirror work I will have to saw off a good few cm from the barrel of the scope.
      So the question is: Is a high quality f6 mirror better than a faster synta f5 mirror for wide deep space astrophotograhy?
       
      All comments gratefully received. 😉
