I went up to Kenley Aerodrome this evening. The sun was setting and of course it was cloudy. But by some miracle the clouds went as the sky darkened. Suddenly I realised I could see the bright dot of Jupiter in the SW, though higher than I expected. Binoculars revealed Saturn at the 11 o'clock position.

I took a few shots with my dslr while hoping to see if the pair of planets became visible to the naked eye. I finally made both out just before 5pm, with a small gap between. It was not the night of the closest positioning (tomorrow) but I was happy to settle for seeing the conjunction almost at its best.

No detail in this image but a super enlargement crop shows a Saturn shaped blob.

James,
That's great.  I could just see them from my back garden between neighbours houses, but too low to image properly.  Looks like tomorrow will be too cloudy to see the closest approach from here.

Well done for grabbing some images of the conjunction James. Like Trev, I managed to see it between some neighbours’ trees with binoculars, but they were way too low from my garden to get a telescope on them. Nice sight though.

Hi Tim et al

The attached is an image from yesterday evening taken using a 12" RC and a Canon 700D.
The image leaves a lot to be desired thanks to atmospheric dispersion but it does show both planets and Jupiter's 4 moons.
The object farthest to the left is HIP99314 which just happened to form a line up. Then it's Callisto, Ganymede, Io (very close to Jupiter) and finally Europa.
In the longer exposures images Titan, Rhea and Tethys are also visible but the planets are wildly over exposed.

Cheers
Brian

Good one Brian.  Is a composite of planets and moons possible with your images, each having the right exposure?

Good to hear that advantage was taken of clear skies and to see and
hear some observations.
Will and I went to a country park nearby which has good horizons and
we tried our luck. Attached are 5 images, a selection of yesterday
evening.
By naked eye Saturn is easily seen above Jupiter; just shows how fast
the planets can move in a day (especially the Earth :).
All images taken with a Canon 70D and 70 - 300 mm lens and various
extents of cropping.

Conjunction, planets over-exposed to show moons

Conjunction, planets exposed to show Saturn better

- IMG-70d_44088_M. jpg 70 mm, ISO 400, f/8, 4 secs.
Conjunction, wider angle to show setting

Hi James,

In theory, yes but in practice I'm not sure.
I will have a look and see but good idea.

Hi Brian

That’s a really good image indeed and certainly one I’d be proud to have taken. You obviously had a reasonable line of sight. Unfortunately, whilst my garden points north east/south west, Saturn and Jupiter were low down in the west and my observatory is situated on the western side of the garden against a fairly high hedge. Impossible to get a telescope on it from there, but it was good to observe visually in the knowledge that others would have better western horizons for imaging.

Hi Brian, Tim and James

That's a great image Brian. One of the best I've seen! Here's the one I
took from my garden on the 21st using a 4" APO... I wish, hehe :-D

Actually it was taken by the WHT 4.2m telescope testing out a new 2
degree field prime focus corrector lens which will be used in the future
with a 1000 fibre optic fed spectrograph.

As its happened, down at home the 21st Dec was a crappy night, but think
I did manage to capture the conjunction before it peed down using an SX
Oculus all sky camera I have on loan. I'll check out the archive and see
if its worth posting ;-)

BTW, many thanks for your Xmas card. Hope you got mine ok?

Cheers,
John

Merry Christmas John and everyone.

That image is quite something!
