Canon 6D for star parties and for astrophotography

    The images in town are not as good. The public likes the Andromeda galaxy and the Orion Nebula. With an eyepiece we only see the center of andromeda but you can see much more live w the 6D. We see the trapezium and the hydrogen gas at the eyepiece but the red color of the gas pops out w the 6D.

    Awesome images. Can you get useful results in short exposures (under 2 minutes) when in town?

    Certain objects are best seen w an eyepiece while others are best viewed with electronic assistance. I often use my canon 6D with a tripod and lightweight mount Ioptron ZEQ25 to travel to a dark site. I use a 200 mm lens (about 12 degrees FOV) or a 60mm refractor w a focal length of 355mm (about 5 degrees FOV). I use an intervalometer to take 1-8 secs exposures. I shoot at ISO 25,000. This allows short exposures that I use for live viewing. I can share these objects with participants at a star party.

    I use the histogram to gauge the correct exposure and take several different exposures. This allows me to observe multiple objects and gives a decent permanent record of what I saw. Since the exposures are short the tracking errors are reduced. I am not aware of any astrophotographers who take quick high ISO photos but I admit that their images are superior.
