Hubble's Variable Nebula15 viewsThe nebula not only varies but does so at the speed of light. How could that happen? The nebula emanates from the variable star R Mon and is illuminated by it. Dense clouds of dust orbit R Mon periodically blocking the illumination. This casts shadows onto the nebula and shadows have no problem in moving at the speed of light. David R.Jul 07, 2019

Below the Cone39 viewsBelow the famous Cone nebula is what looks like a small comet but it is in fact Hubble’s Variable Nebula. This nebula varies in brightness and was a puzzle for many years. Also visible is the very red and very old cluster Trumpler 5 (top right). David R.

Messier 78 & NGC 207152 viewsThese two largely reflection nebulae but with a bit of hydrogen alpha thrown in for good measure are located in eastern Orion and very close to Barnard's Loop. They both belong to the Orion B molecular cloud complex – a star forming region about 1,350 light-years distant from Earth. David R.May 25, 2019

Monkey Head nebula58 viewsNGC 2174 Monkey head nebula. An emission nebula in Orion. 6.5 Ly distant. Cloudy sky prevented longer exposures.

How low can you go? 57 viewsTau Canis Major Cluster is a fabulous open cluster but really needs to be seen from further south than Britain. At an elevation of just 10 degrees I was pushing my luck. I had had a try in 2010 and decided it was time to try again. It is the lowest Caldwell object I have imaged. David R.May 06, 2019

58 viewsNGC 3718 & NGC 3729 are part of the Ursa Major group of galaxies lying 52 million LY distant and above them is the Hickson 56 group of 5 galaxies 400 million LY away. 4.5 hours exposure over 2 evenings with a UHC filter.

A Galaxy points the Way57 viewsThe tiny planetary nebula Abell 4 is Located close to the open cluster M34 and a background galaxy (PGC 2201333) seemingly points towards it. Abell 4 is listed as mag 16.7 and its central star at 19.4 but in imaging terms it does not appear to be that faint. David R.Apr 24, 2019

Polar Ring Galaxy71 viewsNGC 660 is located around 45 million light-years away and is one of a rare class of “polar ring" galaxies, i.e. it has a belt of gas and stars around its centre probably emanating from a collision with another galaxy about 1 billion years ago. The pair of galaxies at the bottom have a common redshift so are probably an associated pair at around 700 million light years. DR.Mar 31, 2019
