M108 is a galaxy about 45 million light years away in the constellation of Ursa Major.  It is sometimes called the surfboard galaxy.   M108 in Ursa Major with TEC140 Technical Information Imaged from my backyard observatory in Nottingham, UK in April 2021 when M108 was almost directly overhead.  I used my TEC140 refractor and Atik 460 CCD camera with Astrodon E series Gen LRGB filters (1.25″).  There is almost 9.5 hours of data in this image consisting of:Lum > 42 x 300s; Red > 24 x 300s; Green > 24x300s; Blue 24 x 300sImage was captured using Sequence Generator Pro software and was guided using OAG on my MESU 200 mount.  Processed with PixInsight and Photoshop 2021 CC.I hope you like it!

M63 is a magnificent spiral galaxy located in the Northern constellation of Canes Venatici, about 30 million light years away.  The galaxy is a member of the M51 group.  There are lots of faint galaxies in the background. M63 – The Sunflower Galaxy Technical Data Imaged from my back yard observatory in Nottingham, UK over the nights of 4th and 5th of May 2021.  I used my TEC140 refractor and Atik 460 CCD camera with Astrodon LRGB filters.  I used off-axis guiding on my MESU200 mount.Integration is a total of nine hours comprised of:Luminance > 30 x 900s binned 1×1 ; Red > 22 x 300s 1×1 ; Green > 24 x 300s 1×1 ; Blue > 24 x 300s 1×1  to give a total of about 8.5 hours of integration time.  Captured with SGP pro and processed in Pixinsight and Photoshop CC.

Background The Hubble Deep Field (hereon-after the HDF) is an iconic image from the Hubble Space Telescope (HST). In 1995 the HST was commanded to stare at a tiny patch of space in the constellation of Ursa Major that is almost devoid of stars and is far from the plane of the galaxy, enabling the telescope to stare out of the galaxy into the depths of the Universe. It did this for about 190 hours with a total of 340 exposures and in so doing captured some of the most distant galaxies in the Universe, some of which are an astonishing 12 billion light years away. Location of The Hubble Deep Field The Hubble Deep Field through the Hubble Space Telescope The HDF is located above the “bowl” of The Plough (or Big Dipper as it is called in North America) asterism in Ursa Major as can be seen in…

M27 is a famous planetary nebula in the constellation of Vulpecula, The Fox. Despite its name, it has nothing whatever to do with planets, it is instead the remnants of a dying star that has cast off its outer atmosphere when nuclear reaction can no longer sustain it. Our Sun will look like this in five billion years from afar. M27 is a fine object to view through a telescope. I have also imaged M27 several times over the years. Here for example. The rendition on this page shows M27 in the HOO or Hydrogen-Oxygen-Oxygen palette which maps the Ha channel to Red and green and Blue to OIII (Oxygen 3). Planetary nebula are rich in Oxygen since it is one of the elements synthesised in the nuclear fusion processes as the star dies.
