  1. Thanks Seb I know what you mean about daytime observing, there's something cool about the fact that these plantets are still there in the daytime sky, it's just that most people don't think they are - like it's a sectret or something! Anyway, I can't do eastern horizon observing from my garden, the house is in the way! So this is the end for me for a bit.
  2. Hello I was sitting at work on Thursday, and I noticed that the sun had come out to play so I went home to do some astronomy, you've got to get your priorities straight haven't you? I set up my scope at about 15:30 and then began to search for Jupiter using my 50mm finder, and my 50mm binos. There was a bit of whispy cloud still in the air, but by 16:30 it had cleared and I was able to spot Jupiter in my finder. The first sketch was made at 16:45. The sun was still 5° above the horizon and the sky in the eyepiece was so bright that it washed Jupiter out quite a lot; a yellow filter helped with
  3. Really good, colours are very, lovely. I have been tempted to have another look at this storm recently, but your sketch looks a lot like mine from over a month ago, I guess it hasn't changed all that much. Was it easy to spot? BTW I like your shadow of the rings on the disc.
  4. Lovely drawing, Roel. It looks just like a photo, but having seen some of your previous work I know that you are simply very talented! no aurorae here, just clouds.....
  5. they're lovely! i really like the delicate thread-like nature of the shading around the outside main features.
  6. Very nice Paul. Did you add a blur to simulate the poor seeing? Mine really needed gif animation to make it swim about on-screen! I too have just been swapping between our drawings, your obs time was getting on for three quarters of an hour after mine so the details are not directly comparable but it is fun never the less. Incidentally i have seen colour in EZ ovals this apparition, i saw them a pink-ish, but recently i keep seeing large white ones.
  7. Hello again here is a drawing of Jupiter from Saturday afternoon. I set up the scope and left it to cool while I searched for Jupiter with my 10x50 binoculars, It took about 30 minutes for me to find it and align the scope to it as it was still broad daylight. Once i got it centred I popped in an eyepiece and the image was terrible, boiling and wriggling about all over the place. Ant V or IV. Things did not improve much over the hour and it made no difference how fast I ran my (considerable) cooling fans, so I can only conclude that the air above me was churning around a high speed. However t
  8. That's a fantastic. I am surprised at the the amount of detail you have seen there. lovely!
  9. Hello Here is a drawing of Jupiter from Friday afternoon. Having already got in some good overtime in the first half of the week, I sloped off early from work and got my scope out. I located Jupiter sweeping the sky with 10x50 binos just before sunset. The seeing was good at first, about Ant II, it quickly became unstable and eventually ended up at Ant IV, but I had to take my son to Hockey practice at half-five anyway! Cold, still, and partly cloudy. The sky was mid blue when I started and faded to a 'midnight blue' by the time I made the sketch. Orion SPX200 with TV 2X barlow and TV11mm plo
  10. Hello Here is another drawing of Saturn. This is from this morning, Thursday 20th Jan. I observed from 05:15 to 07:45, and watched the storm transit the disc. The seeing was okay but not anything special. Ant III, with brief better spells. My best view of the storm was at 06:30 when the brightest part was near the centre of the disc. At this time it appeared as a bright white horizontal strip with a crisp edge, and perhaps a tiny amount of very pale blue within it. The NtrZ proceeding it was pale and bright. Following it, the zone was its usual dull yellowy colour. Still I have not seen the k
  11. Great sketch Seb, lots of detail there. erratic conditions seem to be the order of the day at the moment!
  12. Hello Here is a drawing of Saturn from this morning. Observed from 06:15 to 07:20 0°C with sharp frost, still, clear, seeing started at Ant III, became slightly worse and then got better again, before nose diving at 07:30 to 'Antoniadi - pack up and go inside'. I watched the brighter part of the storm creep onto Saturn's disc over the course of the hour, getting one or two brief glimpses of sharpness, but mostly a soft wobbly view. Still it was better than last time! Interestingly I noted a darker division between the proceeding end of the brightest section and the dimmer 'tail', which I have
  13. Hello Here are two drawings of Saturn from this morning. Conditions were terrible, and any sane person would have stayed in bed, but I have got up early only to be thwarted by the weather for every presentation of this storm on Saturn's CM since I first (and last) observed it on 23rd December, so when I could see the odd star through the clouds I decided to have a go. It was very windy and the sky was full of fast-moving broken cloud, but between telescope vibrations and clouds, I did get enough of a view to make these drawings. In drawing 1 the NtrZ is pale and bright, its right hand half is
  14. Sorry but no. The attraction of each pair of magnets is exactly cancelled out by the repulsion of each pair, so you gain zero propulsion. While the disc is spinning you will generate eddies in each induvidual magnet due to the hall effect, these will cause small magnetic fields which oppose the movement according to Lenz's law. So you start the disc spinning and even if you suspend it in the middle of a vaccuum it will slow down and stop. It would work better without the magnets, like a satellite spinning in space that spins for ever; but it is not a free source of power, it is simply conserv
