Orion Nebula

The orion nebula region as captured from my backyard in Austin, Texas last Saturday night. I had been waiting for that perfect moonless night, free of clouds, but it just wasn't happening. The moon was 2/3 full and about 20 degrees away. I couldn't run very long exposures or high iso, but still I think this is my best effort so far. Still a work in progress, but getting there.


Imaged with a CLS_CCD filtered canon 7D and 100-400mm lens at 400mm riding piggy back on Meade 8" LX200 classic, guided with an orion starshoot and phd. Images captured with backyardeos and stacked with nebulosity.


19x20s@iso400, 19x60s@iso400,13x180s@iso800, and lots of darks for each.

    I agree, this is a very nice image of Orion, despite the sub-optimal conditions! Very well done!
  • Robert Lunetta 3y

    Wow, this is so cool!

    Pulvis et umbra sumus... Haha! Thanks! Bit too much noise in that crop and stretch, but I know what could fix that.
    G Vargas Appreciate it G! I'd love to see you process these shots : )
    Rod HaleyRobert Lunetta Thanks Guys!

    Amazing work!! Do you have pictures of your setup?
  • Barron Fujimoto PRO 3y

    That is incredible! Nice one!
  • Johannes Dag Mayer PRO 3y

    Great shot. Well done!
  • Jeremy Royall PRO 3y

    Bart Huizinga Thanks! Here is a shot of the setup. You can't see the netbook the CCD connects to, but you'll get the idea. Lot of setup!

    That's sick! Do I understand correctly that this system keeps your camera aligned with the stars during the exposures??
  • Jeremy Royall PRO 3y

    Bart Huizinga Yes, this system will keep the camera aligned during the exposures. The telescope is polar aligned and rotates opposite to the turning of the Earth so it generally keeps the object in view. But that is never perfect and you have to give corrections to keep the object perfectly centered. That used to be a manual process (which really was no fun), but they use autoguiders now that send a CCD image from the 50mm finder scope to the computer, the computer program phd, keeps track of the target star you pick and sends corrections to the scope. So that keeps the object centered, and I use another program, eosbackyard, to take all the exposures. Once it is all set up, you can walk away for several hours, let it image, once those are done, repeat the same thing, but with the lens cap on for dark subtraction in post. This is way easier now than it ever has been, but still a lot to it.
