Article on Professor Jocelyn Bell Burnell DBE FRS FRSE FRAS

Following the excellent meeting last Monday with the talk on Women Astronomers by Martin Lunn, the Institute of Physics magazine has just published an article on Professor Jocelyn Bell Burnell. She was recently awarded the IoP’s President’s Medal for her outstandish work in physics, much of which recently has been on encouraging women to go into science. Of course, she is [sadly] known as the women who didn’t get a [deserved] Nobel Prize for the discovery of pulsars [and I don’t think they do retrospective awards]. But she has many other strings to her bow, so I hope you will enjoy the read and learn at bit more about her.

Report on Prof. Monica Grady talk, Lancaster

Eleven EAS members travelled to Lancaster to hear Prof Monica Grady speak on the Rosetta mission. It was an entertaining presentation giving some insight into the difficulties, complexities and timescales of such a mission. We were told why the orbiter and lander were called Rosetta and Philae – it is linked to the famous Rosetta Stone in the British Museum and how this led to the deciphering of Egyptian hieroglyphics. The hope was that this mission would ‘decipher’ some of the secrets of the early Solar System. The instruments, built with late 1990’s technology, were delivered for integration onto the spacecraft in early 2001 and subsequent launch in 2004. The spacecraft flew by several asteroids before hiberbnating for 4 years prior to the encounter with Comet  67P/Churyumov–Gerasimenko (67P)… it did wake on command to much relief and well, the rest we know… The science analysis will go on for several more years.

At the end, there was a lively Q&A with several EAS members asking questions.

 Overall, an excellent evening.


Prof. Monica Grady talk, Lancaster

A talk which may interest members:

Landing on a comet

Wednesday 14 June, 6.30 pm, Lancaster University, Cavendish Lecture Theatre in the Faraday lecture complex.

Professor Monica Grady (Open University)

ESA’s Rosetta spacecraft was launched in 2004, arriving at its target comet in July 2014. The Philae lander was deposited onto the comet’s surface in November 2014, operating for 70 hours before its battery failed.

Monica Grady was scientific advisor to the lander’s Ptolemy instrument team. In her talk, she will relate what it was like to land an instrument on a comet, and discuss some of the results from the mission.”



Holiday photograph… North America Nebula

On a recent holiday in the Scottish Borders near Jedburgh, I managed to find a short lived gap in the weather – between the strohg wind and the clouds, imaging was impossible. I drove about 10 miles from Jedburgh towards the Cheviot Hills and found [combining OS maps and Google Earth is wonderful!] a possible imaging site if the weather played fair. The site was brilliant with exceptionally dark skies and no light pollution.

Eventually it did for a brief time. I got set up with a few problems and lost some time by being greedy by trying to run two cameras simultaneously – one widefield in the hope of catching a few early Perseid meteors and one on a Williams Optics 72mm telescope on my Skywatcher goto mount. For some reason, focussing the widefield lens didn’t occur smoothly so as I saw cloud approaching, I started imaging with the WO scope and an astro-modified Canon EOS400D [the usual internal red filter that blocks the red light from nebulae has been removed]. I managed three shots – one of 3 minutes exposure, one of the planned four minutes [I was hoping for more] and one of 2 minute until curtailed by a flat battery. Then cloud arrived…

The image is of the North America Nebula, NGC 7000. Situated close to Deneb in the constellation Cygnus, it is a vast cloud of excited hydrogen.

Moral, don’t be too greedy!

Images from Mercury transit

The Mercury transit of the Sun was interesting last Monday. Hard to say it was spectacular but when you think what you are actually looking at… But the weather couldn’t have been better in Kendal – for a change!

It was an interesting photo opportunity but with the planet being so small, it was hardly a visual treat even with telescopic aid. However, that we could see it against the Sun was good. Normally in the twilight sky it is quite a challenge to find it if you didn’t know which of those faint ‘stars’ it was… Still fascinating to think that that is a real world passing between us and the Sun, albeit one only about 40% bigger in diameter than our moon. and less than 40% of the diameter of the Earth. At less than 60 million km from the Sun [Earth is 150 million km away], it is a stark place as recent NASA Messenger probe showed in some detail for the first time.


A few of my images. A still taken at 16:11 GMT. Nice sunspot groups – one oviopus group and a much smaller one between Mercury and the large group. Taken through my 8″ Meade LX200R fitted with a Baader astrosolar film filter.


A time lapse video of most of the transit – well at least until the Sun dropped behind a telephone pole and then into trees. The gaps coincide with me putting the camera on a solar scope and also a disloded cable on the laptop running camera [Astrophotography tool] making it go onto hibernation – fortunetly I spotted it quite quickly. The odd ‘cloud like’ bands running through towards the end are telephone wires!


Finally a comparison of a white light image with that from the solar telescope. The main spot group is faint at H alpha wavelengths but the small group is quite prominent. Several filaments are obvious.


EAS observing session March 9 2016

Wow, that was a good Eddington Astronomy Society of Kendal observing session – probably 15 people learning about the night sky from Simon and looking through several different telescopes with different capabilities. Sky got hazy about 21:30, so we packed up. I must admit, the pint in the New Union, only a few minutes from home, afterwards was excellent.
Lots of Messier objects, i.e. faint fuzzies, seen through my 8″ scope – M42, the Leo Triplet of galaxies M65, M66 and NGC 3628 in the same visual field – nice to see them naked eye after imaging them last Monday night – M51, M101 [both difficult] and the spectacular doublet of M81 and M82.
The star of the night must be Jupiter which was spectacular – all 4 moons put on a show although two were being rather shy and hiding. I managed to connect a webcam – Philips SPC900NC – and demonstrate video image capture. The stacked image [Registax] is much better than I expected – probably because I tweaked the scope collimation on Monday night. Pleased with that. Couldn’t see the Great Red Spot trough the eyepiece but it is clearly there in the processed image.

Polaris from a static camera on a tripod – series of 15second images spaced by 15 seconds over 90 minutes.

I also pointed a camera at the Pole Star and captured a series of 144 15 second exposures with 15 second gaps between them over approximately 90 minutes. I removed images with aircraft in them or light from torches of people wandering about! The remaining  images I combined using the free Startrails software There is an interesting object occurred about 19:14 which may be a satellite flaring or a meteor at approximately ‘7 oclock’ on the image. No Iridium flares were predicted around that time.

First Deep Sky imaging for months


It isn’t my best ever picture by a long shot, but at least it is a picture. The weather has been so attrocious that nothing has been possible. Short glimpses between clouds has been the best I could manage so far since about October. Anyway, managed to grab a few shots of Orions Great nebula, M42. Quite pleased given the difficulties on the night given that my mount decided not to autoguide properly. I used my Meade 8″ LX200R mounted in equatorial mode on my yard pillar in Kendal. The telescope had a f6.3 focal reducer attached to increase the field of view giving an effective focal length of 1260mm. I used my red-filter astro-modded Canon EOS400D at ISO1600. I took quite a few shots which I didn’t use for various reason  poor, trailed stars and cloud!  The final image is a composite of 227 seconds in total, comprising 1×120 seconds, 1×60 seconds, 1×20 seconds, 3×9 seconds subframes. These were overlaid in Photoshop to produce the final image – the shorter exposures allow the bright central portions of M42 to be not burnt out – they certainly were in the longest exposure.

Clearly, it needed more light but given the frustrating passage of clouds and the telescope issues, I’m quite pleased with the result. As Liz, my wife, said ‘You’d have been really pleased with that a few tears ago…’ To true but the better you do, the higher the standard you expect!

Perseid meteor article

There is a really good article on the Persied meteors by Pete Lawrence on the BBC website ‘how-to-watch-the-perseid-meteor-shower’. Forecast looking good for Tuesday night but less good Wednesday [Metcheck: 50% cloud at midnight 30% cloud after midnight] and bad Thursday night/ Friday morning. I’m thinking of heading out tomorrow evening to Orton to get east of Shap quarries and hopefully a good dark eastern view. Ian
