    Astrophotography! M8, M20

    Finally got out to do some astro work with my astrotrac. I'm really liking it, super easy to setup (compared to my other huge mount)...and good results too...

    I've got a bunch of pics to go through, but here's the one I've been able to process so far.

    this is M8 (aka lagoon nebula, the largest one on the bottom portion of the screen)
    M20 (aka the Trifid nebula, which is the smaller pink and blue one just above M8)
    and M 17 is up at the top left corner (akla omega nebula)

    taken at 135mm, f2.2, 30s, ISO1600



    I might need to reprocess it, my eyes are starting to get tired..

    So is it just that dark out there or is the FX sensor doing a lot more work? Because I dont get anything like that here.
    But I also have city light about 12 miles away.

    its really that dark. I live pretty close to some of the darkest skies in the country (excluding perhaps Alaska)...although the FX sensor does allow me to shoot at a higher ISO and retain less noise, and higher ISO will be more sensitive to the light....remember though that cameras see light differently than us, this is a 30s combination of all the light hitting the sensor, what we see is instantaneous. so while the naked eye can see the band of the miliky way (the bright yellow/orange across the frame) seeing the pinks and blues of the nebula aren't really something we can do unassisted.

    I did do some minor processing (lowering blacks, raising exposure, etc)...astrophotography raw files tend to be fairly flat because you're basically exposing a field of black with some stars on it.

    Here's another shot, this is the same M8/M20 area as above, but a little different/closer crop...This is also a stack of ~9 images at 135mm ranging from f2.0 to f3.2, ISO800 to ISO2500, and 20s to 30s

    I was also trying to be a little less heavy handed in the processing of it as well.
