The Leo Triplet in a Widefield

Leo Triplet In Widefield

The Leo Triplet is a popular trio of galaxies in the constellation of Leo, popular with amateur and professional astronomers alike. They are visible in the late winter and spring in the Northern Hemisphere. Consisting of M65, M66 and NGC 3628, the galaxies are about 35 million light years away. NGC 3628 was never given the distinction of as Messier number for some reason, even though it is as bright as the other two members. The image was taken with my Samyang 135mm DLSR lens coupled with Moravian G2-8300 cooled CCD camera with Astrodon RGB filters. It consists of seventy minutes (5 minute exposures binned 1×1) in each of the red, green and blue filters to give a total integration time of three hours and thirty minutes. The triplet was about 45 degrees above the horizon when the exposures were captured. IT was then processed with Pixinsight and Photoshop. The…

SADR Region of Cygnus

Sadr Region 26 August 2019

SADR is the central star of the Cross of Cygnus, between the arms of the cross. The constellation of Cygnus is supposed to represent a swan but to most people looks much more like a cross and consequently is often called The Northern Cross. The whole area abounds in nebulosity that is very easy to capture with a camera. This image is taken with a Samyang 135mm DSLR lens and subtends a field of view of about 8 x 6 degrees across the sky and so the long axis of this image is about sixteen moon widths wide. This is a very large area of sky to capture in one image. It is was made from 12 x 3 minutes exposures in each of the Red, Green and Blue and also a luminance of 24 x 3 minute Hydrogen Alpha 3nm exposures to give a total integration (exposure) time of…

M36 Open Cluster in Auriga – FSQ85

M36 Open Cluster

M36 is an Open Cluster of stars (as opposed to a Globular Cluster) in the Constellation of Auriga.  M36 is high overhead in Europe during the nightimes of winter months and is one of three Messier Open Clusters in Auriga, the others being M37 and M38.  All of these are visible in a small pair of binoculars as nebulous and fuzzy blobs.  M36 and the other clusters make a fine site in a telescope and dozens of stars can be seen.  Note also the Red nebula to the top left – NGC 1931 (Sh2-237).  There are some tiny PGC catalogue galaxies, billions of light years away in this image. M36 Open Cluster in Auriga This image was taken from by backyard in Nottingham, UK on the 24th January 2018 with my Takahashi FSQ85 refractor and Moravian instruments G21-8300 CCD camera with Astrodon RGB Generation 2 E series filters on MESU…
