  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. Hey, Please download the latest driver from the following link. Feedback is always welcome http://pegasusastro.com/wp-content/uploads/2017/05/iOptron-Mounts-2013-by-Pegasus-Astro-Setup.exe_.zip Thanks!
  3. In case someone is interested here is the new 1.4b release of my driver for older 2013 protocol ioptron mounts: https://www.dropbox.com/sh/bj31h4cj71g9vjx/AADbpsVuyHrHe8MzcMIDrmaHa?dl=0
  4. 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. Luminance taken by Angelos Kechagias with an Atik 428EX on a Nikon 50mm Lens, RGB taken by Evangelos Souglakos (me) with an Atik 4000 on a Canon 50mm Lens. Both lenses were stopped at f/5.6. Filters: LRGB Baader Sub-exposures: LRGB 5mins Total time: 4h per panel Processing in Photoshop by Angelos Kechagias. Full resolution in: http://www.celestialpixels.com/Nebulae/i-XSNF9zH/A
  5. California Nebula - Sony A7S/Tak Epsilon

    Epic what Sony and a fast lens can do! I would bet that this picture was captured from a CCD with regulated cooling @ -20. I really like your processing and the star color. Very smooth and delicate! Great image and thanks for sharing!
  6. M81 + M82 and just a squidy of IFN

    Wow, very nice result. I love the IFN and your color calibration
  7. 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) Reduce a little bit the stars to bring the nebula into surface (I did it with carboni tools in PS) 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 Play with selective colour in photoshop to enhance other colours in the reflection nebula (blue) Thanks, Evans
  8. 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.

  9. The Rosette nebula

    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
  10. The Rosette nebula

    The Rosette Nebula in the constellation of the Unicorn (Monoceros). Telescope: Takahashi FSQ85 @ f/5 Camera: ATIK 460EX Filters: Baader LRGB Subexposures: 5mins L, 3min RGB (bin2x2) Total Exposure: 6h Location: Near Gythion , Greece Full resolution: http://www.celestialpixels.com/Nebulae/i-KxsjRKK/A
  11. NGC 660 - The Polar Ring - When Galaxies collide

    Very very nice result. The background, the star color and the galaxy detail is great!
  12. Markarian's Chain in Virgo

    Thanks guys, My purpose was the bring the IFN up "to the surface". In full resolution you can count multiple galaxies. The target is very difficult and needs extra caution in processing to keep the SNR in good shape
  13. Heart Nebula Reprocess

    Very nice result! I strongly believe your second re-process is the best one. Don't fade the stars in this target. Star colour make beautiful this frame
  14. It's not the season for this target but eventually I found nearly a day of time to process all these crazy data I was gathering for 2+ years. Telescope: Takahashi FSQ 85ED Camera: QSI 683L Filters: Astrodon LRGB Gen2 Total Exposure Time: ~ 22h L + 12h RGB Location: Mt Parnon, Greece (2014-2016 data collected every May) Better resolution: http://www.celestialpixels.com/Nebulae/i-4Gz7QBs/A
  15. I'm selling my Canon EOS 5D Mark II (Body only). The camera is in pristine condition with 16500 clicks. No cracks/ scratches, no dust. I used it for daylight photography and never for astrophotography or timelapses. That's why the camera has a small number of clicks. I have the original box, manuals , battery + 1 spare. Price is: 750 pounds. Thanks,
