                                             M104 - The Sombrero Galaxy (WideField Version)

     Widefield version of this galaxy has it's own beauty. Seeing it in it's own neighborhood, small sized, surrounded by bright stars and many other galaxies give to it a bit of different impression. While processing it I could easlily spot at least 20 galaxies around it, but the low amount of data didnt gave me the SNR needed to recover them from the background noise. But it's still possible to note the brightest of the smudges.


     I didn't want my image of the Sombrero to look ordinary, that's why I left the framing as imaged, in vertical position, this adds something different to the image. Secondly, I didn't want to left it with large bright halo as we used to see in many other images on the web. I wanted that the impression of a Mexican Hat still be there and the bright halo would be visible, but I also were interested that the inner details, up to the core would be visible too. And this does look very good, at least to my taste it does.


     As for the annotated version of this image, I decided to mark all of the globulars clusters, that I had identified in the cropped version, here too. Becides the original ones, I had to identify the rest of them which now became visible in this wider field of view. 29 more globulars have been added to the image which spread much wider from the galaxy, making it in total of 139 identified globular clusters in whole image.
