    Default New Rig for Astro Imaging

    This setup is not ideal for galaxies but this old Skywatcher 80ED punches well above it’s weight.

    Bought this just before the real mass production started, the quality assurance did a good job, I still use this scope twenty years later.



    M101 - The Pinwheel Galaxy



    M27 - The Dumbbell Nebula



    The Sunflower Galaxy



    The Sombrero Galaxy



    M13 - The Great Globular Cluster in Hercules



    The Needle Galaxy



    Thor’s Helmet Nebula



    M51 - The Whirlpool Galaxy

    A mainly digital setup with a musical amplifier and endearing 1970's speakers. A CD player that hardly ever gets used and a turntable that is good enough to remind my how enjoyable my old vinyl is. Some cables and things.

    That’s M27 - The Dumbbell Nebula in the constellation Vulpecula.

    It’s classed as a planetary nebula because of it’s shape.

    Fantastic images Tony!

    How long does a typical exposure take?

    As long as you want really Barry. The camera I’m using is cooled to -10 from ambient temperature.

    This helps with noise reduction. The biggest factors are really noise and signal to noise ratio.

    The more data you capture, the better the signal to noise and the therefore, the cleaner the image.

    The camera I’m using is a CMOS chip, which unlike CCD chips benefits from lots of shorter exposures (120 or 180 seconds) rather than a few long exposures (300 seconds or more).

    Typically, I’ll try to capture at least 2 hours worth on any target (60 x 120s) but for a good image, I’ll usually try to capture at least 3 or 4 hours in multiple sessions.

    It’s a game of two halves, capture and integration. The trick is getting competent at both of these very different skills.
