This is a RGB image of The Moon captured at about 20:00 on 15th December 2021 from my observatory in Nottingham using my TEC140 refractor and ASI174MM camera.I captured two capture runs in each filter and stitched the resultant images together in Photoshop.  Each video capture file was 9GB in size.

M33 is a galaxy about 2.8 – 3 million light years away in the constealltion of Triangulum. Alonf with M33, it is one fo the Lcoal Group of galaxies with which our own Mily Way galaxy shares the local universe. M33 is the most distant object that the 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.…

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…

North American and Pelican Nebulae with Samhyang 135mm and QHY268C This is my first ever image capture with the excellent NINA software.  I used my widefield rig which consists of the Samyang 135mm lens and QHY268C OSC camera using an IDAS 2″ LP filter.The image set is a modest 18 x 180s exposures, all binned 1×1.  Pre-processed and processed in PixInsight and a few tweaks in Photoshop.
