M33 NGC 598 Triangulum Galaxy

Newer Older

I decided to reprocess M33, the original was too red, too noisy and over saturated. I hope you like this version.

This is another Collaboration with Andy D'Arienzo, he shot the Ha from New York using his TMB. For my part the LRGB (color and luminence) was shot from Fremont Michigan.
Total Exposure time 19.5 hours

This was my first attempt and old version shot in 2009 for comparison using the QHY8 on the TMB130

M33 is a spiral galaxy at approximately 3 million light years distance in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598, and is sometimes informally referred to as the Pinwheel Galaxy, a moniker it shares with Messier 101. The Triangulum Galaxy is a member of the Local Group of galaxies, which includes the Milky Way Galaxy, the Andromeda Galaxy and about 30 other smaller galaxies

    Hy Terry, I prefer the second version on my monitor it's more natural!
    Well done

    Terry, I'm partial to the previous version, but both are nice. Well done.

    Awesome! That's an incredible amount of data! And really great processing.
    I do like your new processing better.

    Thanks friends for the comments, probably one of my best imaging sessions so far with just perfect weather.

    As some of you who know me fairly well, I have a habit of turning a bad situation into good without realising it. This time around I have a broken filter wheel on the cam so each time I shoot I have to also shoot flat frames before shooting using the next filter as the camera needs to be removed from the filter wheel in order to manually move the filters.
    Because of this I am shooting all night long on each filter :)

    I sent all the raw data to Andy who used CCD Stack for stacking and post processed in CS2. This is his version.


    CS and Happy Shooting
