These two images were taken from the Jodrell Plank Observatory within twenty four hours of the closest conjunction of Saturn and Jupiter on the 21st of December 2020. Prior to this, we captured a number images using a variety of camera-lens combinations. - Kurt Thrust current Director of the Jodrell Plank Observatory.
Using the 66mm Altair Astro Doublet refractor as a telescopic lens, we captured this image of Saturn (centre left) and Jupiter (centre right) with its retinue of four Galilean Moons. Sadly the resolving power of this set up was insufficient to show Saturn's rings or its larger moons!

The northern winter constellation Orion is now a prominent feature looking south on a clear night. Alpha Orionis, otherwise known as Betelgeuse, is back to its brightest best after a recent period of dimming. Professional astronomers have decided that previous estimates of its size had been too great and now believe it to be a third of what was originally thought. If this is true, estimates of how long this red supergiant star has before it goes supernova will have to be extended.
Other features to note are:
This image of Alnitak and the Flame Nebula was taken at the Jodrell Plank Observatory using the 127mm Meade Apo Refractor. If you look closely at Alnitak , at about 10 o' clock, you can see one of its two fourth magnitude companion stars. Alnitak is a hot blue supergiant over thirty times more massive and 21,000 times brighter than the Sun. It is estimated to be over 1000 light years distant from Earth.
The Horsehead Nebula is approximately 1375 light years distant from Earth. It is quite large and seen from our perspective covers approximately 6 square light years. The Horsehead Nebula is a mixture of hydrogen gas and dust. The bright star Sigma Orionis seen to the left and below the nebula is ionizing the gas behind it and causing it to glow, the dust prevents us seeing this and creates the dark Horsehead Nebula as a darker region. The Horsehead Nebula is an active location for the formation of low mass stars. When viewed at infra-red wavelengths the Horsehead Nebula is transformed and glows. The astro-imager Robert Gendler's 'Astro Photo of the Day (APOD)' , created from data captured by large professional telescopes, is well worth a look!

Our student Reggie Stax spent an hour or two on the 18th and 19th of November trying to capture any 'straggler' Leonid meteors. Sadly he was unsuccessful but inadvertently he managed to take this widefield view including both NGC1499 and M45.
The California Nebula NGC 1499 is an emission nebula located in the constellation Perseus close to the boundary with Taurus. The nebula is so named because it looks like the outline of the American State of California. It is almost 2.5° long on the sky and, because of its very low surface brightness, it is extremely difficult to observe visually. It lies at a distance of approximately 1,000 light years from Earth. It shines due to excitation of the Hydrogen β line in the nebula by the nearby energetic O7 star, Xi Persei also known as Menkib. Menkib is the bright star to the centre and right of the nebula as seen in the above images.
The Geminids meteor shower is next up and weather permitting should put on a good show on the evening of the 13th and early hours of the 14th of December. The Moon will be out of the way so this year should be good as long as the clouds keep away.
Another unique astronomical event worth seeing is the conjunction of the Solar system's two largest planets - Saturn and Jupiter. In reality a vast distance separates the orbits of Jupiter and Saturn but every now and again they line up as viewed from Earth. This year is rather special as to the unaided eye they will appear as one bright star. They will have an apparent separation of only 6 minutes of arc, the last time this happened was in the 1600's. Bearing in mind the 'festive season' its rather nice to have a bright star to observe during December. The planets will be at their closest on the 21st of December 2020 but good views will be had from the the 16th to the25th. The new Moon will also be nearby in the sky just after sunset on each of these days. The planets will only be visible for a short period just after sunset and you will require an unobstructed view to the western horizon. We will try to image this rare event using the Observatory's mobile rig set up in the nearby churchyard. - Kurt Thrust current Director of the Jodrell Plank Observatory.

"The red planet has and continues to, put on a splendid show this year. The atmosphere was not at its most stable when Pip and Reggie captured a number of video clips at about 21:30 pm on the 11th of November. These images were processed from the final clip taken on the night. Mars is now several weeks past opposition and is therefore showing a gibbous phase. As the year advances the phase will decrease and its overall apparent size will decrease as Mars and Earth move further apart and move around their respective orbits.
This week we will be hoping to capture some images of the Leonid Meteor shower using the Observatory's Canon 600d DSLR and the Sky Adventurer 'mini-rig' - Kurt Thrust current Director of the Jodrell Plank Observatory.

" Full credit to our student and assistant Reggie in taking advantage of the excellent stable atmosphere over the Jodrell Plank Observatory last night to capture some great videos of the planet Mars. I think this Mars image is the best we have managed to capture and process at the Observatory. The southern polar cap along with some associated cloud is clearly visible. Cloud is also apparent towards the western and northern limbs. Albedo features of interest are:

" As the weather continues to be poor in Lowestoft, I have amused myself by reprocessing some of the video clips captured earlier in the month by our student assistant Reggie Stax. We believe the circle of white clouds in the centre of the image formed over the extinct shield volcano Olympus Mons. Olympus Mons covers an area of 300,000 square kilometres which is roughly the area of Italy. It is 21 kilometres high or approximately 2.5 times the height of Everest" - Kurt Thrust current Director of the Jodrell Plank Observatory.

" Since the night of the 20th of September, the weather in Lowestoft has been exceptionally inclement! Between broken cloud and rain showers, we managed to glimpse the Harvest Moon close to the very bright and 'pink' planet Mars. . We are hoping that the weather will improve in order that we may capture some more images of Mars using the Observatory's large refractor.
To keep the team busy Joel Cairo has been encouraging our sponsors Anita and George Roberts to provide the cash to purchase Topaz Denoise AI a software package capable of improving 'the signal to noise ratio' in the Observatory's images. Pip and Reggie have been helping me to evaluate the software using a trial download. The above image was processed using Topaz Denoise AI (the AI stands for Artificial Intelligence - we can do with a bit of that around here). The stars Deneb, Sadr , Delta Cygni and Epsilon Cygni are well displayed. The North America Nebula NGC7000 is clearly visible. We also tried Denoise AI on a planetary image of Saturn. We are quite impressed with this software and hope the JPO budget can stretch to purchasing it!" - Kurt Thrust current Director of the Jodrell Plank Observatory
" We decided to spend some time in the Jodrell Plank Imaging suite processing the video clips a number of different ways using a range of processing software packages. These two images, stacked from two separate videos, were considered to be the best from the night".- Joel Cairo CEO of the Jodrell Plank Observatory.
