Hi all, not posted on usenet for a long time! Here's a shot of Jupiter I took with my C-14 on the night of September 3/4 2010. This particular shot was taken just as the planet's giant moon Ganymede was exiting from Jupiter's disk. http://www.digitalsky.org.uk/jupiter...9-45_RGB15.jpg Thanks for all the comments. The image was taken using a high frame rate camera to generate 3x AVIs, one for each colour channel. Each was then processed via Registax which, combined wih the camera, is the "seeing-busting" element of the processing workflow. |

I was worried that my comment might have been taken as an insult or as skepticism, instead of just a statement of the obvious (to most participants in the forum) for the benefit of those to whom it might not be obvious.

I was just getting desperate regarding the orbital mechanics martian meteorites here; and you gave back the meaning of reading this newsgroup in a picture. Thank you. -- mrr |

I was just getting desperate regarding the orbital mechanics -- mrr Well Morten,I would say the inability to count the 1461 daylight/ darkness cycles from Mar 1st 2009 to Feb 29th 2012 corresponding to 4 complete orbital circuits of 365 1/4 rotations of the Earth is an amazing sight to behold,especially as you are all convinced there are 366 1/4 rotations of the Earth in an orbital circuit.For a short while it will remain an issue of unfamiliarity,something people haven't thought through with any degree of effort however the additional rotation on Feb 29th needed to square away the 6 hour orbital lag to allow the 365/366 day calendar system to exist as a convenience represents that 365 1/4 rotations correspond to an orbital circumference,circuit and period. Your belief in 'sidereal time' reasoning as a personal choice would be fine,similar to that of a flat Earth ideology, were it not that it intersects with the education system therefore the imaginative idea that there are 366 1/4 rotations per orbital circuit,in conflict with what the body experiences and the arithmetic of the calendar dictates cannot be allowed to exist for any length of time regardless as to how indoctrinated one may be.People are too intelligent and value reasoning too much to not accept the correct correlation between 365 1/4 rotations and an orbital period and circuit. You can't bury yourselves in imaging ,this would only be a disgrace were it not corrected rather than trying to hide that horrific error that arose in the late 17th century that is 'sidereal time' reasoning applied to planetary dynamics and the 'orbital mechanics' built on that catastrophic reasoning. |

The second stage is taking this 24 hour average and determining that the orbital cycle is 365 days 5 hours 49 minutes based on the yearly return of a star to a meridian.As the number of daily rotations never exceed a full 365 rotations in one orbital cycle,the fractional 5 hour 49 minute difference represents the equivalent amount of rotation needed to correspond with an orbital circumference. The genius of the calendar system as it ties in with daily and orbital dynamics in converting raw daily and orbital cycles into a steady and linear progression of days and years without considering the fractional discrepancy between the number of rotations per orbital circuit and the separate orbital geometry and orbital motion itself is the way the fractional 6 hour difference is set aside in each non-leap year and squared away when the fractions make up near enough one full rotation on Feb 29th.The additional daylight/darkness cycle leap day accounts for the orbital distance traveled thereby completing 4 full orbital circuits containing 365 1/4 rotations and the calendar convenience which registers it as 3 years of 365 days and 1 year of 366 days. The nice thing about this Martin,as it is the usenet,it that within a few weeks these posts get washed over like an incoming tide washes away footprints in the sand.It leaves individuals to walk on fresh ground for a change and enjoy as best they can what others have done before them and what was done was truly amazing for the good of heart and those with a lively imagination tempered by interpretation. |

I am a beginner in these things. Can you please explain or provide a ref. to what a C-14 is? Is that a lense that you attach to a digital camera or a telescope? -- Best regards, Pete Lawrence http://www.digitalsky.org.uk -- PMatos |
