Taken last night in very windy conditions – not much to see as the “interesting” side is turned away from us.

This was the Moon last night – 4 days after New Moon. The middle picture shows the “earthshine” where the night time part of the moon is illuminated by Sunlight reflected back from the Earth to the moon. (This is a long exposure so the sunlit part of the moon is very over-exposed. The third picture if of the crater Petavius.

Above are the results of 5 hours work yesterday evening. Short video’s of Jupiter taken every ten minutes with the aim of making a short movie to show Jupiter’s rotation (It rotates very quickly – once in about 10 hours!). However it was not to be as the clouds rolled in for an hour midway through the sequence! So Bizibilder made a map instead by using some software (WinJupos – freeware) to “unroll” the surface details and stitch them together again.

Todays Sun with new processing to show far more surface detail – otherwise as normal. Bizibilder suddenly found he had clear skies after all the weather stations (TV and Web based) said the day would be cloudy – so much for their supercomputers!!

Bizibilder has had a play with todays Sun image in order to try and bring out more information from it. It started life as exactly the same image stack as today’s posted “Sun’s” but he has reworked the Photoshop processing to bring out far more surface detail. It takes longer to do and is quite a bit more complicated but he reckons it may be worth it? All he has to do now is try and remember exactly what he did!

Just have to paint the beastie and I can have a “semi permanent” set-up for winter Solar imaging (the very low winter Sun cannot be seen from Bizibilder’s observatory). Beats having to carry a tripod and mount outside and back just to take a few pictures!

A few shots of Jupiter from last night - very windy and poor seeing but at least I was able to get a few shots of the transit of Io and its shadow. I've never observed this phenomena before and it was quite spectacular to see it for myself for the first time. The shadow of Io seemed to be racing the great red (yellow!) spot across the disc. Unfortunately I had to pack up before the shadow transit was complete. You can certainly see Io itself on the better quality images later in the sequence. All done with the 180 Mak and SPC900.
The black dot is the shadow of Jupiter’s moon Io. Io itself can be seen in the lower sequence of images as a light coloured dot near the right hand edge of the planetary disc (It is very easy to see in the 7th picture where Io is almost touching the edge of the disc within the lower of the two cloud bands). If you could stand on Jupiter (you can’t – its a big ball of gas!) at the position of the black shadow you would see a total eclipse of the Sun caused by Io!

Last nights Moon pictures: Taken with the 180 Mak-Cass and Canon 100D for the large disc picture and SPC900 and 2x Barlow for the craters. Seeing fair. The large disc is a mosaic of two panes each stacked from 54/58 individual frames - luckily the moon just fitted across the camera sensor!
A couple of images of Jupiter taken last night. The seeing wasn’t all that good with quite a bit of high cloud around. You can see the “Great Red Spot” (looking rather yellowish!) at the right hand end of the lower brown belt. To its left there is quite a storm raging that continues across most of the visible disc.

To save his lawn from further damage Bizibilder has just paid out to have a path laid to his observatory – all done in less than half a day! It would have taken Bizibilder several weekends of hard graft. Bizibilder does not do hard graft.

This is Bizibilder’s first night’s images of the “Great Nebula in Orion” or M42. This image is one and a half hours exposure (in 5minute “subs”) with a second set of 10 mins (in 30 second “subs”) to capture the detail in the bright “core” of the object. The two images were combined in Photoshop. At the top you can see the “Running Man” as a shadow in the upper gas cloud. Bizibilder intends to continue to image this object over the next few weeks (weather permitting) and add some depth and detail. He has one slight problem in that a neighbours tree gets in the way and only allows around two hours of data collection at a time.

Last night Bizibilder managed to add (see – Last night before fog, below) a further 4hours 5mins (to make a total of 6hourd 15mins!!) on this galaxy. It is in the constellation Triangulum and is about 2500 Light Years away.
Bizibilder thinks that this target is now “done” and he will move on to something else…….

One heck of a struggle today with galeforce winds! I took 150 DSLR shots (ISO 100 and 1/800 sec) and only stacked 57 of them after I (and the stacking software between us) had rejected the rest for various degrees of "wobblyness"! No chance of a webcam close-up in these conditions - just too much movement (I was using my tripod mounted EQ5 and Evostar 120 as I can only see the Sun from a part of my garden away from the observatory at this time of year). After all that struggle we have a nice line-up of spots right across the disc and a new AR just creeping round the limb.

This object – The Great Orion Nebula or M42 - is coming within range of Bizibilder’s telescope again (see post in March for an earlier view). This is a single 5 minute exposure of this object, hopefully Bizibilder can get some decent clear skies to finally get an image that does it justice!

The galaxy M33 was the target last night and Bizibilder manages to collect 2h 30mins of data before the fog came down (boy was it quick! One “sub” was clear as a bell, the next fully “fogged out” – all in five minutes!). I had intended to try and get around 6hours – so the image will have to be finished on another night as what you see here is a little “noisy”.

Bizibilder has imaged this star cluster again (see Dec 2010). This time 2h 30min exposure to show the gas that is being illuminated by the young blue stars of the cluster passing through it. These were taken on the evening of 17th Nov. Bizibilder took a second nights images and then had to scrap the lot as dew had ruined them!

Left is a picture made from a stack of 64 DSLR images. Right a picture made from a mosaic of twelve small frames each made using a 1200 frame webcam movie. Processing was as near to “the same” as Bizibilder could manage. Both images were taken within half an hour of each other on 13 Nov 2011.

Finally a picture of the Sun again! Bizibilder has either been at work or clouded out for quite a while. The Spot group 1339 is by far the largest seen during this Solar cycle so far and Bizibilder nearly missed it!! Another day and it would have disappeared around the edge of the visible disc. Apologies for the dodgy spot close-ups but the Sun is now very low and the sky was quite hazy when these images were taken. These are from the image shown in “Big Sun” in the post below, cropped for the Blog.
Click on the above to see the “full sized” image that Bizibilder gets through the telescope. Like the Moon picture below this is a stack of single DSLR images – the only filter is Baader Solar Film. Canon 1000D ISO100 1.320sec. You get quite a good impression of the Sun’s overall surface granulation in this picture.

This was taken at 20.15 GMT on 10th November 2011 – which is at exactly Full Moon ie 100% of the visible disc is illuminated by the Sun – and the whole of the other side of the Moon’s globe is in darkness – truly “The dark side of the Moon!”.
