"The freeware Starnet GUI works its magic on the Pleiades asterism bringing out detail in the the reflection nebulae. This group of young hot blue stars is currently passing through a cloud of interstellar dust which reflects the starlight. The Pleiades or the Seven Sisters is a relatively close open cluster of stars and is estimated to be some 444 light years distant from the Earth. The data for the image was captured at the Jodrell Plank Observatory in 2018"-. George Hammer resident geologist at he Jodrell Plank Observatory.

The Andromeda Group of Galaxies
Slightly different colour rendering
" The original data for this was captured in autumn 2016 using a Altair 66mm doublet refractor mounted on a Star Adventurer EQ mount. When Pip Stakkert processed this data back in 2016, the outer spiral ring was not visible. The new freeware Starnet GUI in combination with Affinity Photo 2 has enabled fainter details to be displayed. We were astonished to see how well this little telescope performed capturing the outer spiral ring wrapping around M31 anticlockwise from right to left. A plume of stars and gas can also be seen spiralling away from the smaller elliptical galaxy M110 bottom right. There is plenty of drama in this image as the galaxies gravitationally interact.
To give some idea of scale; Messier 31- the large spiral Andromeda Galaxy is approximately 150,000 light years (1.35 million trillion kilometres) across and contains stars with a mass equivalent of 1 trillion Suns. At the centre, somewhere in the bright core is an intermediate mass black hole with a mass equal to 100,000 Suns. Messier 32 can be seen in the image as a small blurry disc just above and to the left of the bright Andromeda core. It is an early type dwarf elliptical galaxy comprised of mainly old yellow and red stars. Messier 110 is also a dwarf elliptical galaxy and both M32 and M110 are gravitationally bound to Messier 31 as satellite galaxies. The trio of galaxies is located some 2.5 million light years away. M31 can be seen with the naked eye from a dark site and all three can be viewed with a good pair of binoculars" - Kurt Thrust current Director of the Jodrell Plank Observatory.

The Practical Astronomy Show Kettering 2023
Anita and George Roberts co-sponsors of the Jodrell Plank Observatory |
"Our sponsors Anita and George enjoying a day at the Practical Astronomy Show at the Kettering Conference Centre on the 11th March 2023. Many thanks to the nice guy on the TUFFTRUK stand who kindly offered to take the photograph. Very nice sturdy engineering for astronomers on the move on show from TUFFTRUK.

"Whilst we were out imaging the aurora over Lowestoft we noticed that the constellations Leo Major, Virgo and Coma Berenice were getting higher in the south eastern sky. Many galaxies are located in and amongst these constellations, which is collectively known as the 'Realm of Galaxies'.

Messier 37 revisited

" It turns out that taking good photographs of stars with a DSLR is quite difficult. The constellation Auriga is a favourite target at the Jodrell Plank Observatory. It holds a quite a few interesting objects, one of which is the wonderful open star cluster Messier 37 also known as NGC 2099. The cluster is on the edge of our galaxy, the Milky Way. When viewed from Earth, we observe M37 looking in the opposite direction from our galactic centre. The stars are approximately 500 million years old and have a combined mass of 1500 times that of the Sun. Amongst the cluster stars are at least a dozen red giant stars and one planetary nebula (toward the end stage for stars roughly the mass of our Sun). The cluster is approximately 4500 million light years away and covers an area of sky equivalent to about 25 light years. The cluster has over 500 identified stars gravitationally held together. The cluster can just be seen through binoculars from a dark location as a small hazy cloud. There are two other Messier open star clusters in Auriga. The red glowing clouds visible in other parts of our image are created by ionised atoms of hydrogen gas and cold dark dust in the interstellar medium" - Kurt Thrust current Director of the Jodrell Plank Observatory.
