    Default M31



    Here is my latest attempt at imaging M31. This is 5 10 minute subs, ISO 800. 9 dark frames were used for calibration with Nebulosity 3. This was taken through a Skywatcher ED100, using a Celestron .63 focal reducer. I think the focal reducer caused the chromatic aberration that is visible, as it is not matched to that telescope. I will try again in a few days from a darker site with the proper .85 focal reducer.

    Hey Dean,

    That is a great image with good detail edge to edge. I am surprised you didn't burn out the core with 10 minute subs!

    It's getting better and better Dean! And I don't notice that much CA, certainly not nearly as much as what I would get with my SW 102mm. Also note that some software packages are really good at handling CA like StarTools.

    Regardless, this is a very nice image.

    Well done,
