    Amateur astrophotography has come a long way since back in the day when we did it using film.

    Digital photography allows 'stacking' images to enhance detail, and image stacking software allows us to 'erase' or average out the various types of digital image noise (read noise, dark current noise, thermal and amplification noise).

    It is my intention to direct TPF members to outstanding examples of amateur astrophotographs in this thread as I become aware of well done astrophotographs.

    These winter nights the Orion constellation and it's associated star forming clouds (nebula) of interstellar gas is easily visible. For me here in Iowa at about 42° north latitude Orion is in the southern quadrant of the night sky. The Orion Nebula gets no more than 40° above the southern horizon here, and would be lower still at higher latitudes.

    In this astrophotograph the image data was accumulated by Robert Fields at a private, roll-off roof observatory in Howell Twp, MI.
    The telescope and camera used.

    SBIG STL 11K Research Grade astronomy CCD camera

    While I find this idea kind intriguing and the images very cool, do you think you would garner more interest in the landscape or general forum?

    Hard to tell.
    The night sky is just one part of Nature.
    Hard to call a shot of the sky a landscape.
    General is a catch all.

    this stuff is incredible, I really want to try some deep space stuff soon. I don't have access to a telescope or mount but my buddy has a tracker he's going to let me try out during the next new moon

    The only details I know about how this HaLRGB mosaic image was made are that a Mamiya RZ 110 mm lens and an astronomical CCD camera mounted on a guided motorized equatorial mount using a homemade adapter were used.

    The image is of the Orion constellation and in addition to it's associated stars has in it:
    • Bernard's loop - the long red arc of gas in the lower left of the frame
    • The Orion Nebula
    • The Running Man Nebula
    • The Horsehead Nebula
    • The Flame Nebula
    • Messier 78.

    Be sure to click and zoom in so you can see the exquisite detail in the mosaic.

    Here's an oldie I took of Thor's helmet. I was never good at this stuff. I never understood the RGB stacking to get the wonderful colors that everyone else gets. lol @KmH , do you have any pointers or can you lead me to a tutorial that'll teach me how to color these things?

    Wonderful job of capture and processing. Hard to believe you did this with a four inch refractor, even if it is a Tak.

    I have not made any of the astrophotos posted about in this thread. So far.
