    Default First Image using Equinox 80ED



    Hi Guys,

    Here is my first astrophoto using my new Skywatcher Equinox 80ED.

    I'm still new to astrophotography and I'm still trying to learn how long my exposures should be.

    The image consists of 10 x 120s images at ISO 200, 10 x 60s Images at ISO 400 and 4 x 30s exposures at ISO 800 totaling 42 minutes of exposures.

    The images where dark and bias substracted and stacked in Deep Sky Stacker. The final processing was done in Photoshop CS4.

    If anyone has any suggestions or reading material regarding how to correctly process DSO images in Photoshop I would really appreciate it. I'm really struggling to get it right and know what to do when.

    Regards.

    Equipment Used:

    Skywatcher Equinox 80ED (Imaging Scope)
    Skywatcher 70mm Refractor (Guide Scope)
    Celestron AS-GT 5 Mount
    Meade DSI Pro (Guide Camera)
    Canon 350D Unmoddified Camera.

    Excellent first AP mate , well done . Only tip I would give you would be to look at Layers in PS , get a short exposure for the Trap' ( with 80ED you should get the three main , maybe four stars there ) and layer them into the final shot , thus avoiding the core becoming blown out .

    Really good shot here. I found the book in the link below to be more then helpful with processing.

    AstroBrandy, this is a great image and the processing you made is very good. Maybe few flat images will help with the small black spots. Also you can try to get some shorter exposures and using "layered mask" trick to get more details in the Trapesium area (take a look here: Compositing 2 Different Exposures via Layer Masks). A good "curves" tutorial can be found here: Astro Imaging Tutorial Learning to Use Photoshop Curves. It can help to get more of the Running man and fainter parts of the nebula
    Clear skies,
    Ivo

    May the weather be with you!
