    If you mixed (layered) the two so you kept the dust and stars but a toned down M31 then this could be really fantastic! Looks like some great data

    i like the framing and crop of this. i really like the brightness of m31 along with good star color.

  5. Anna (www.eprisephoto.com) (4 months ago | reply)

    My comment may not have sounded right .... I meant that they are both great but I think that a version that kept the core of the darker, but all the dust and the fantastic star color of this one would be APOD worthy!

    Thanks astrographer,
    I like this simple framing and star color, too. North is up.

    Thanks Anna as usual.
    Exposure for one hour was a little too long for my equipment, and star trailing got visible due to frame rotation, which is the result of my misalignment of the polar axis and autoguiding.

    I hoped to image stellar streams around the great galaxy in Andromeda. The result shows that it was successful partly. Southern giant stellar stream looks trivial and shorter than expected. There looks to be dark nebula in the foreground of the direction, and the giant stream looks shorter, not giant. We may need some means to distinguish stars of the galaxy from stars and gas of our galaxy. Such means must be, I feel, beyond our reach. I like the dynamic figure of the galaxy, though the center part got a little too bright near saturated.

    I hope you don't mind, I downloaded both the dark and light versions and had a play to show you what I meant (its snowing here so I can't go image myself and this was just fantastic data). I used the dark one in various stretches and worked it into your lighter version. I would love to take data like this for M31 - I now have a new standard to shoot for with it. Here is my processed version using your jpgs:

    Thanks Anna, I feel your version too strong, though.

    I made another version myself. I like this natural feel.

    Yeah for some reason Flickr "sharpened" everything up when loaded, it was much softer and less harsh overall on both my computers. Evil Flickr. Either way I just did a quick layering so kept all the outer dust from your light one rather than starting from scratch with your darker version. Still fun to play around with :-) ... I'm loading up a new version that I like better, I will link it on your new version so you can see if you like it.

    Ah...this lady
    Yes...she is a smart one ...:)
    Regarding Pixinsight....
    It has so many lovely tools....although after 3 years I feel I use only 25% of them..

    Thanks Anna and dave,
    I do not know "wavelet" at all now, but I will try and learn it with PixInsight.

    He uses J Misti's M101 as a source...
    I had a play with it also recently

    More awesome stuff here Hiro, I am always happy when I check your photo stream.

    Thanks AWelsh. I am happy at the comment, too.
