JUPITER and its MOONS
Both images taken with a Celestron 5se scope and a QHY5L-II camera. A Celestron 2x Barlow was used for the closeup image.

The Transit of Venus - 6th June 2012
The transit of Venus as seen from Cala D'Or, Majorca at sunrise on the 6th of June 2012. I managed to find an accessible location on the rocks by the coast to view the Sun as it rose out of the sea at just past 06:20 local time (GMT +2), but, as you can see, the transit was almost over by then! Fourth contact (when Venus left the Sun's disc) was at approximately 06:55.
It was very hard to get a sharp focus with the Sun barely above the horizon but it's good enough and several Sun spot groups are visible on the disc.
The image was taken with my Canon EOS550D and WO Zenithstar 80, with a home made solar filter, mounted on a lightweight camera tripod. The exposure was 0.6 seconds at ISO 200, although, in hindsight, maybe a higher ISO and shorter exposure may have resulted in a sharper image. No image processing has been done other than a spot of cropping.
New Pier, Setup and Photos 23rd May 2012
We are pleased to announce that thanks to two local companies for their help and support, WYAS have two piers currently in production for use on our telescope pad. The material for the piers has been donated by EDS Demolition from part of the material from the old Tetley's Brewery currently being demolished in Leeds. The time and manufacturing resource is being provided by Gardner Denver Ltd. The construction work on the piers in nearing completion and the first full height pier was brought to site for initial setup and positioning. The second shorter pier should be completed in a few weeks. This will allow easy access and use for wheelchair members / visitiors and visitors from cub, scouts and guide groups.
The pier was assembled and our 10" Meade SCT was mounted on it and used visually during the normal Tuesday meet. A web cam was mounted on the scope and the images taken are shown here. Later as the Pole Star was seen, a rough initial Polar Alignment was done so that the final pier mounting points could be marked. The pier has been returned to Gardner Denver where it will be painted and then returned for final installation.
Star Trails
14th April 2012 
Thought I would have a go at a simple Star Trail. This one was done using my Canon 40D DSLR, a 17-35mm Lens set at the 17mm end (Camera effective size 17mm x 1.6 due to crop ratio or 27mm). This photo is 540 exposures at 15 secs @ISO 500 stacked with CS5 HD Merge option.
Saturn - 27th April 2011
I used Registax to produce this image from a video taken using a Canon EOS550d Digital SLR. It's a first attempt at this kind of thing for me, so plenty of room for improvement, but the image clearly shows the Cassini division in the rings, the cloud bands, and maybe, just maybe, some of those white storms in the northern cloud belt.The video output from the camera is .mov format, which Registax doesn't like, so it's a bit of a faff to convert them to uncompressed .avi, but, in true Yorkshireman fashion, I found some free software on t'internet to do the job.
I'll try and do a better job on Jupiter when it comes around in the Autumn.
Jupiter and Uranus - 08Jan2011
Not a spectacular image but it isn't often that you can fit six prominent Solar System objects into a field of view smaller than the Pleiades! On the left is Jupiter with the four Galilean moons, closest to Jupiter is Io followed by Europa, Callisto and Ganymede. On the right of the image is Uranus.Taken with a Canon EOS 550d sat on my Skywatcher 200p. It was a 1 second exposure at ISO800.
Moon - The Southern Highlands. 14thJan2011
I took this image of the southern highland region using the WYAS 14" and my Canon EOS 550d. The seeing was quite bad but I managed to get a fairly sharp shot with a fast shutter speed. The craters Tycho (centre) and Clavius (with the arc of craters on the floor) are nicely illuminated. No processing has been done on the image other than cropping out the poorly lit RHS.
Jupiter and Ganymede
Taken on Friday the 3rd of September with a webcam and a Vixen VMC260L, through poor seeing and thin cloud. Not the best with regard to quality, but interesting. If I'd caught the situation earlier I might have set up to do a longer series and made a video of it, but all well and good in hindsight.
The four were taken soon after each other and all within about 10 mins. Of course when I'd got home it cleared up, as always.
Processed in Registax and Photoshop.
Jupiter and Io - 100831
Taken on the 31st of August with a webcam and Vixen 260. A very hazy night, with seeing limited to about mag 3. But it has a steadying effect on planets, so more of a plus.This is a good year for Jupiter as it rises quite high in the sky, after two years of keeping very low in the south, so make the most of it. It needs a long focal length, the big Meade should produce good results, and if the seeing is good, add a barlow.
Processed in Registax using 444 frames, out of 2000 taken.
That's Io in the bottom right hand corner.
Vesta
This is an animated gif file, made of two frames taken in March this year, without a telescope, naked DSLR? It's of the dwarf planet Vesta, as it was passing through Leo.
If you click on the picture you'll get a larger one and be able to see the animation.
The Moon - 56hrs old
The 56 hour-old Crescent Moon as seen from WYAS on the 16th of April. The image was taken using a Canon EOS 550d attached to the Televue 102 in the dome.
As the sky got darker I was able to capture the Earthshine using the same equipment but a longer exposure.
