  1. The Veil Nebula is a diffuse nebula located in the northern constellation Cygnus, the Swan.
    Also known as Witch’s Broom Nebula, Bridal Veil Nebula, Cirrus Nebula, or Filamentary Nebula, it constitutes the visible parts of the Cygnus Loop, a supernova remnant in Cygnus. It is located at an approximate distance of 1,470 light years from Earth.
    In this wide shot you can see the three main parts: the Eastern Veil, the Western Veil, and Fleming’s Triangle (Pickering’s Triangle).

  2. This four panel mosaic gives an incredible widefield view of one of the most colourful regions in the night sky. A collection of intricate dust clouds, reflection, emission and dark nebulae and background globular clusters makes this a fascinating area.


    All data captured previous summer (end of June) in Mt. Parnon Greece @ 1430m. We finally found some time to process and merge all of them in one picture.

  3. Mike,

    You have very good data and a stunning frame. With all do respect I edited your original photo and made some enhancement.

    I believe you should do three things: (and this is what I also did)

    1. Reduce a little bit the stars to bring the nebula into surface (I did it with carboni tools in PS)
    2. Play with the colour balance.  Your frame is FULL of Ha (red colour). Lab colour in photoshop and increase contrast in a and b channels. Increase saturation also in RGB
    3. Play with selective colour in photoshop to enhance other colours in the reflection nebula (blue)

  4. The two dark nebulae (LDN 1621, smaller, near the left border and LDN 1622, much bigger near the center) are projected onto a complex and extensive emission nebulosity known as Barnard's Loop, inside the molecular cloud complex named Orion B. Both nebulae are believed to be 500 light years away, much closer than the bright red hydrogen nebulae that shine behind them from about 1,600 light years.

  5. Thanks guys for your comments. I really like the diffraction spikes and yes the best way to do it with a refractor is to use fishing line. Next time I'll try that option. The reason I didn't place the fishing line was to see if the field is fine the stars that FSQ85 captures. I believe in this target the spikes give a very nice effect especially in the heart of the rosette. 

    Thanks again

  6. Seems an easy target but it isn't. Need time to improve S/N ratio. There is a huge Ha area on the left, I was fooled and tried to remove the "gradient" :)

    Hope you like it! Thanks!

    The nebula Messier 78 (also known as M 78 or NGC 2068) is a reflection nebula in the constellation Orion. It was discovered by Pierre M\xc3\xa9chai
    n in 1780 and included by Charles Messier in his catalog of comet-like objects that same year.
    M78 is the brightest diffuse reflection nebula of a group of nebulae that include NGC 2064, NGC 2067 and NGC 2071. This group belongs to the Orion
    Molecular Cloud Complex and is about 1,600 light years distant\xc2\xa0from Earth. M78 is easily found in small telescopes as a hazy patch and invol
    ves two stars of 10th magnitude. These two stars, HD 38563A and HD 38563B, are responsible for making the cloud of dust in M78 visible by reflectin
    g their light.

    LBN 534 is an isolated and elongated molecular cloud in the constellation of Andromeda. Either shock fronts from a supernova or ionization fronts from a massive star could have caused the shape of this cloud as well as the spatial distribution of young stars. The blue reflection nebula, vdB 158, is located at the southern end of the cloud. The nearby bright B9.5V star, HD 222142, illuminates VdB 158.

  8. The well known Triffid Nebula - M20.

    I took Luminance data using my GSO RC10 (reduced to f/5.6) & QSI683L. Unfortunately I didn't have time to capture color but I had these color data since 2011. When I shot this target using my old WO FLT98 and my lovely ATIK314L camera. Well this is why the target cropped at rectangular shape. Hope you like it :)

  9. NGC 7129 is a reflection nebula located 3,300 light years away in the constellation Cepheus. A young open cluster is responsible for illuminating the surrounding nebula.

  10. I love this target. I had never shot it using a wide field setup. Nebulae and star color match perfectly in this frame.


    The Cave Nebula, Sh2-155 or Caldwell 9, is a dim and very diffuse bright nebula within a larger nebula complex containing emission, reflection, and dark nebulosity. It is located in the constellation Cepheus.

  11. My attempt for this twisted galaxy :)


    NGC 3718, also called Arp 214, is a galaxy located approximately 52 million light years from Earth in the constellation Ursa Major. This galaxy has a warped, s-shape. This may be due to gravitational interaction between it and NGC 3729, another spiral galaxy located 150,000 light-years away

  12. A nice target in Gemini. This cosmic jellyfish is part of bubble-shaped supernova remnant IC 443, the expanding debris cloud from a massive star that exploded. Light from the explosion first reached planet Earth over 30,000 years ago.  An emission nebula cataloged as Sharpless 249 fills the field at the bottom right. The Jellyfish Nebula is about 5,000 light-years away

  13. VDB 14 & VDB 15 in Camelopardalis


    These two  reflection nebulae are a small part of a large dust cloud in the constellation Camelopardalis. vdB 15 is the blue area to the top and vdB 14 is the sickle-shaped blue nebula down. At a distance of about 3000 light years, magnitude 5 and magnitude 4 supergiants respectively illuminate them.

    Thanks for watching
