  1. Thanks guys, glad you like it Here's a tip, try using a W#11 (yellow) filter for examining the boundaries of the belts and zones, it really helps bring out the details and is a good all round filter. I also find it helps with the white ovals in the STB. -Paul
  2. Greetings all, and happy 2014 to you all! The skies are finally starting to clear, and here is a recent strip map I made of Jupiter which shows almost a half rotation. The seeing was quite reasonable for a time and I was able to observe some nice details in the belts and zones. Best wishes, -Paul
  3. Thanks all. Yes, thanks heavens for setting circles- everyone should know how to use them in my opinion, they're invaluable
  4. Greetings all, Please find a drawing of Venus I made this afternoon. I used setting circles to find the planet, and this is probably the largest phase I have ever observed the planet (~97%)! Seeing wasn't great, but it was nice to make a start on the current elongation. Illuminated disk: Seemed to contain some subtle shadings- one darker one near the limb though it is hard to be sure. Unilluminated Disk: Not seen Terminator: Geometrically regular Cusp Caps: NPC seemed to be brighter Cusp Collars: NP collar seemed to be marginally more prominent, hard to be certain. Best wishes, -Paul
  5. It was a truly splendid event- a hearty congratulations to the organizers for delivering a slick and polished show! Nice to meet so many of you all in person as well!!! Best wishes, -Paul
  6. Thanks to you all for your kind remarks, it really does mean a great deal to myself and the rest of us that both Patrick and the program is so well loved and highly regarded. Patrick very much wanted the program to continue after his passing, he often said this. He also wanted the program to continue with the team he had put in place. I will pass on your best wishes to the rest of the guys. If you've not already found it, further information on upcomming programs, times of transmission and other stuff can be found at our website here: http://www.bbc.co.uk/programmes/b006mk7h Let the good w
  7. Hi all, hope you enjoyed tonight's program, a lot of hard work went into it and I think it was truly magical. I hope we did Patrick proud. The Sky at Night programs I spoke about on Twitter will be presented by Chris Linttot, Pete Lawrence, Chris North and myself. I thank you all for your support. Best wishes, -Paul.
  8. Greetings, happy new year to you all! Here's some reasonable drawings of Jupiter made in perfect conditions! Strangely, we had a late clearing on 3rd January and the seeing was superb for many long periods of time. I was able to examine the disk and satellites at x400 and record an above normal amount of detail. Alas the clouds rolled in at 2316UT, but I was more than happy with the night's work (though a full rotation would have been excellent). By the way, if you don't know, the next two Sky at Night programs after tonight- will be looking at the Sun in February, and in March we shall be
  9. Greetings all, The sky cleared here last night and produced some good seeing for some time. As a result, I observed the planet from 2012UT to 0305UT and was able to produce the attached half rotation map. I was rather surprised by how prominent Oval BA was, and the dark section of the STropB which seems to touch the GRS. Some fascinating structres in both the SEB and NEB. Best wishes, -Paul
  10. Many thanks! To answer your question, the GRS has demonstrated much variability, both in size, colour and intensity over the last 150 years or so. The spot seems to be contracting, but when the SEB fades, the spot tends to become much darker and redder, then as the SEB revival occurs and the SEB returns to its former self, the GRS becomes much more pale. Quite why this should be the case, or the precises mechanisms by which this occurs are not wholly understood at this time. Best wishes, -Paul.
  11. Greetings all, Attached are two drawings of Jupiter I made on the 21st November. Seeing was rather variable, but there were a number of interesting features present: Drawing 1: Shadow of Ganymede near the proc. limb. Seeing variable. A number of dark sections present in the SEBz, GRS coming onto the disk. Ganymede in transit but not seen. NMumber of festoons in the EZ, and a number of darker sections in the NEB. The northern edge of the NTB dark and irregular. Drawing 2: Ganymede now nearly off the disk. Some wonderful detail in the SEB just fol. the GRS. Seeing has improved somewhat.
  12. Greetings all!! Attached are 5 disk drawings and a strip map I made on the night of 05-06 November 2012. After a month of almost continual cloud cover, the clouds parted and I was able to observe the planet from 2200UT- 0510UT. The main of rthing of interest was an enormous rift which was present in the NEB. The rift was rather obvious, and by making transit timings, I estimated it to be some 35 degrees long. It was hard to say if the rift was one long rift or a series of smaller ones whose boundaries were beyond the resolution of the telescope. By 0407UT, oval BA and the GRS were on show
  13. To be honest, it really doesn't matter too much about the make of the eyepiece, so long as the glass is a reasonable make. I have a mixture of wide angle and some standard plossl eyepieces. You will no doubt here advice about choosing the most expensive eyepieces, but I would ignore that personally, none of mine are particularly expensive. The main tool you need is time. When most people have a go at visual observing, they have a quick five minute look and declair that all they can see is a white disk with one or two bands on it. Well yes, that is the first impression, but you have to wor
  14. Thanks all! @James, they're called festoons, and they have been well documented by Jupiter observers from at least the 1800s. Like everything else on Jupiter, there is some variability in their frequency and contrast since the EZ seems to undergo periods when it is not as active as at other times. A red W#25A filter helps to enhance them visually.
