    Default M31 - Andromeda



    This is an ongoing project, not sure whether it's going to work by adding more subs now.

    Taken with a 5D2 and a 300mm lens at f/4.5 on an HEQ5 Pro mount. This is a mixture of subs all taken at 1600 ISO. Stacked in DSS and processed in CS3.

    Lights 17 x 120, 25 x 91, 45 x 60, 39 x 44, 11 x 30, 29 x 29, 13 x 14

    Darks 19 x 120, 4 x 91, 38 x 60, 28 x 44, 8 x 30, 13 x 29

    I think I am suffering from LP - Would I be getting something different in dark skies or by using a LP filter? I really want to get more out of the spiral arms.

    Nicely Done! Great image!

    You mentioned you want to get more detail in arms, you may try bumping up your exposure time to 4-5mins and see if that brings out more of the arm structure. The image looks great! Thanks for sharing!

    Thanks Jeff - Unfortunately, I am working unguided, so I'm almost maxed out time wise. Any other ideas about what could be done?

    wow looks great for me...i agree you need more exposure time for finter details, processing more aggresive can help.

    If I add more subs - What exposure time would be best? More of the same?

    I have added another edit, using another editing programme - I think the results speak for themselves, I think PS will be going in the bin!!
