Rosette Nebula In Very Wide Field Image taken with a Samyang 135mm DSLR lens and QHY268C Colour CMOS camera in January 25th 2023 when high to The South. A total of 30 x 120s exposures at F4. Used NINA software for image acquisition and processed in PixInsight. I wanted to set the Rosette in a very wide field so as to see the surrounding nebulosity.I have imaged The Rosette Nebula before with a FSQ85 telescope which can be found here.

Sh2-171 in Cepheus Sh2-171 is a star forming region in the constellation of Cepheus in the far northern hemisphere of the sky. Imaged here with Takahashi FSQ85 and G2-8300 with Astrodon HaRGB filters.
M33 is a galaxy about 2.8 – 3 million light years away in the constellation of Triangulum. Along with M33, it is one of the Local Group of galaxies with which our own Milky Way galaxy shares the local universe. M33 is the most distant object that the human naked eye can see, appearing as a ghostly white smudge on a very dark night from clear skies. It is a magnificent spiral galaxy about half the size of our own galaxy. M33 Galaxy in Triangulum I’ve imaged the galaxy multiple times. For example, with the same FSQ85 telescope here and also at a closer image scale with the TEC140 refractor here. This time I have set the galaxy in a slightly wider field by utilising the FSQ85 0.73 reducer. I used the Moravian G2-8300 CCD camera and Astrodon RGB filters all binned 1×1. I did not use a separate luminance channel.Data…
M31 is one of the most favoured and popular imaging targets in the night sky; it is bright, large and very photogenic. I have imaged this galaxy numerous times, for example, in this LRGB version and in this OSC version. Since the galaxy is so large, each of these images is set in a wide field, one of 3 degrees horizontally and 2 degrees vertically across the field of view which equates to six times the diameter of the full moon. Many newcomers do not appreciate how large these objects are in the sky. Large but VERY dim! M31 in OSC from a QHY268C and Takahashi FSQ85 refractor The above image is at a resolution of 4.16arcsec/pixel. On such a large object as M31 this allows the entire galaxy to be imaged in one field of view on a wide field refractor such as the FSQ85 but does not allow…
M108 is a galaxy about 45 million light years away in the constellation of Ursa Major. It is sometimes called the surfboard galaxy. Technical Information M108 in Ursa Major with TEC140 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 300s Image 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!
