Messier 45 in the Constellation Taurus

"Last night there was a three hour break in the clouds over Oulton Broad and Messier45, or the Pleiades open star cluster, was visible above the Observatory. As we have never imaged this target at a low to intermediate focal length, we decided to give it a go. The image is from a stack of 1 minute and 2 minute exposures at ISO1600. Just over 2 hours of data in total was used to create the image. The equipment employed was: a modded Canon 200d DSLR, a triband filter and a Samyang 135mm F2 lens, (the F ratio was increased by using filter rings). The cluster is quite close to us at 444 light years and is clearly visible to the naked eye on a dark and clear winter's night. The 'reflection nebulosity' is being created by starlight reflected from a cloud of gas, which the hot blue cluster stars are currently moving through. The reflection nebula cannot be seen with the naked eye but if you can see and count seven stars you have excellent eyesight". - Joel Cairo CEO of the Jodrell Plank Observatory.

" In the end, Messier45 is all about the nebulous gas cloud the cluster is currently moving through. I therefore asked Kurt Thrust to reprocess the data and emphasise the 'wispy nebulosity' which surrounds the brighter elements" - Carl Segine  Outreach Officer at the Jodrell Plank Observatory.

" Many thanks to friend of the JPO, Prof Greg Parker, for recommending the excellent software StarSpikes4 Pro. The application of this software is a 'gamechanger' in adding heightened sparkle and colour to stars. Literally StarSpikes4 Pro adds lustre to our clusters"! - Joel Cairo CEO of the Jodrell Plank Observatory

Whats up in January 2018


The Rosette Nebula and open star cluster NGC 2244 - Taken with the Observatory 127mm Meade Apo-refractor - 0.8x focal reducer and field flattener, Canon 600D DSLR guided with a QHY5-L11 guide camera - image by Pip Stakkert.
" After an extended period of bad weather and 'Christmas festive activities', opening up the observatory for a night and early morning of observing and imaging, made for a pleasant change.
What a wonderful night it was, clear skies over Lowestoft from noon on 07 to the early hours of 08 January 2018. Winter in the northern hemisphere provides a number of treats for the astronomer and astro-imager, amongst them; the Rosette Nebula in the constellation Monoceros the Unicorn, the Orion Molecular Cloud- Messier 42 and the Pleiades open star cluster in the constellation Taurus. In addition a faint comet is currently visible amongst the stars of Taurus.
The open cluster NGC 2244 was first discovered in 1690 by the astronomer John Flamsteed. It is approximately 5000 light years distant and comprises young energetic stars emitting copious amounts of ionizing ultra-violet radiation. The nebula, glowing red, is a region of interstellar  ionised atomic hydrogen. In this case hot class 'O' stars have blown an ionized 'bubble' in the gas. Many new born stars are currently hidden within the cloud but eventually stellar radiation will blow the clouds away to reveal their presence at optical wavelengths. NGC 2244 may be seen with binoculars and small telescopes but spotting the nebula visually requires a larger telescope and a dark site. The red colour of the nebula is only revealed by photography". Archie Mendes - visiting astrophysicist at the Jodrell Plank Observatory.

"The Pleiades, also known as the 'Seven Sisters', is a nearby open star cluster thought to have formed some 100 million years ago from a nebula similar to the Orion Molecular Cloud. It is moving through an unrelated cloud of interstellar dust some 440 light years distant in the constellation Taurus. The central part of the cluster may be contained within a radius of 8 light years. Hot 'B' type stars are very luminous and their blue starlight reflects off the dust through which they are travelling creating a 'reflection nebula'.  The stars are linked by gravity and share a common proper motion but it is estimated that the cluster will only survive for another 250 million years after which it will disperse due to gravitational interactions with its galactic neighbourhood. catch it whilst you can!  - Kurt Thrust current Director of the Jodrell Plank Observatory.

"This visualization is an excerpt from a longer sequence that explores the Orion Nebula using both visible and infrared light. Two correlated computer models were created based on visible-light observations from the Hubble Space Telescope and infrared-light observations from the Spitzer Space Telescope.
As the camera flies into the star-forming region, the sequence cross-fades back and forth between the visible and infrared views. The glowing gaseous landscape has been illuminated and carved by the high-energy radiation and strong stellar winds from the massive hot stars in the central cluster. The infrared observations generally show cooler temperature gas at a deeper layer of the nebula that extends well beyond the visible image. In addition, the infrared showcases many faint stars that shine primarily at longer wavelengths. The higher resolution visible observations show finer details including the wispy bow shocks and tadpole-shaped proplyds. In this manner, the movie illustrates the contrasting features uncovered by multi-wavelength astronomy." NASA

"The Orion Nebula, Messier 42 or NGC 1976 is visible to the naked eye as a blurry star in the middle of 'Orion's Dagger' hanging below Orion's Belt.  It is one of the brightest nebula in the sky and at a distance of approximately 1350 light years, it is the nearest massive region of star formation to Earth.The Orion Nebula has revealed details about star formation in collapsing clouds of gas and dust. Astronomers using large and satellite telescopes have directly observed proto planetary discs, brown dwarf stars, the turbulent motion of gas and the ionizing effects of young massive stars in the nebula"

"At Magnitude 13.45 this comet requires a good telescope to see it clearly. The above top image was taken as it passed by the open star cluster 'The Hyades' - off on its vast journey into the depths of space". - Archie Mendes - visiting astrophysicist at the Jodrell Plank Observatory.

" After an incident at the Jodrell Plank Observatory Christmas Party and by mutual agreement,  Mr. Ronald Clump will have no further connection with The Observatory, its professional staff, its premises and the Board of Trustees.  Our current Director, 'Kurt Thrust' will, until further notice, be acting CEO of the Jodrell Plank Observatory". - Doris Jansen on behalf of the The Board of Trustees
