Close Up Study of The Great Andromeda Galaxy M31 with TEC140 and FSQ85

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…

Nebulae 22 March 2023

North American Nebula in a wide field with Samyang 135mm and QHY268C camera

North American and Pelican Nebulae with Samyang 135mm lens and QHY268C Camera This is my first ever image capture with the excellent NINA software. I used my wide-field rig which consists of the Samyang 135mm lens and QHY268C OSC camera using an IDAS 2″ LP filter. The wide angle view brings out the North American nebula (NGC 7000) and The Pelican nebula to its right very nicely. There is also a lot of other background luminosity in the image.The image set is a modest 18 x 180s exposures captured in August 2021, all the data being binned 1×1. Pre-processed and processed in PixInsight with a few tweaks in Photoshop.

The Leo Triplet with TEC140 and QHY268C

The Leo Triplet is a popular and famous group of galaxies in the constellation of Leo, best viewed in late winter/early spring in the Northern Hemisphere. They are often imaged together like this as the triplet or as individual galaxies. They are located about 35 million light years away and consists of the Messier galaxies M66 (top left in the image), M65 (bottom left ) and to the right we have NGC 3628, commonly called The Hamburger Galaxy. The galaxies are easily visible in a small to mid-sized telescope as faint smudges in this isosceles triangular pattern. The galaxies are sometimes called the M66 Group but ask any astronomer and they will immediately know what you mean if you mention the Leo Triplet! Another famous galaxy group in Leo is the M96 group. The Leo Triplet Technical Details Image captured from my back yard observatory in Nottingham, UK on the…

Open Clusters 23 March 2023

M45 – The Pleiades

Easily visible with the naked eye, M45, The Pleiades – sometimes referred to as The Seven Sisters, is a well known and famous Open Cluster in the constellation of Taurus. IT has been known since ancient times due to its prominence. The cluster is located between 450-500 light years away and contains several hundreds member stars. The cluster is quite young by astronomy standards and the cluster is moving through a cloud of gas which is easily visible in images and can been seen visually in a dark sky as well. M45 – THe Pleiades Technical Details Imaged from my backyard in Nottingham on Saturday 9th January 2021 when high to The South. A meridian flip occurred half way through the data acquisition. I used my Takahashi FSQ85 refractor and QHY268C One Shot Colour camera. The image was created with quite a small data set of only 38 x 180s…

The Moon, 24 Dec 2020, FSQ85 and QHY268C

This is a one shot colour picture of The Moon through my Takahashi FSQ85 telescope and my QHY268C colour camera. Seeing between bouts of cloud dodging was quite good with very little in the way of shimmering. This is the best 40% of 5000 frames captured with Fire Capture. I did not use the full resolution of the QHY268’s 6000×4000 sensor, I just captured the central 1600×1200. Unusual to see the FSQ85 used as a planetary or lunar scope but it does excel at this as well as deep sky astrophotography work. It is also a very good instrument for visual observations.Processed with Autostakkert, PixInsight and Photoshop. I hope you like it. It could do with a bit more colour to bring out the colour in the Mare (sea) regions. The Moon 24 Dec 2020 with FSQ85 and QHY268C
