Thanks, Astro0; I spent a few minutes trying to do that and gave up.

QUOTE (Stu @ Nov 12 2010, 02:45 AM)  It's not a race...... Room for everyone Really really agree. Good on you for saying that Stu, especially as you're one of the main contributors who has been posting here since pretty well the beginning. I really appreciated your comments when I first got going. It motivated me to do more, squeeze time in in the evenings and keep learning!! This is one of the great things about UMSF. Also I think your site is great...... I visit it from time to time - It keeps getting better and better and more and more comprehensive as you keep learning and expanding your skills and knowledge. It exemplifies what a passionate amateur can do. Wikipedia - An amateur (French amateur "lover of", from Old French and ultimately from Latin amatorem nom. amator, "lover") is generally considered a person attached to a particular pursuit, study, or science, without pay and often without formal training... and reflects a voluntary motivation to work as a result of personal interest in the activity. |

Yes, it's oft inferred or assumed that amateur is the opposite of professional, when it's not. The driving difference, is a salary.

Another transit was imaged...

QUOTE (Floyd @ Nov 12 2010, 01:57 AM) Sure looks to me like Oppy drove right across a crater Wow! I was thinking drivers are avoiding such crossings at all costs - old filled craters might be filled by fine dust, making them dangerous sand (dust?) traps. Is't Spirit sitting in a buried crater trap right now? I wonder how rover drivers determined that it was safe to cross this crater? |

At first glance you'd swear blind that Phobos is curling round the Sun in those images! (And yes, I know it does over a Martian year before any pedantic fans leap in there!) Neil |

QUOTE (Astro0 @ Nov 11 2010, 08:46 PM) Rather than try and pick it out of the glare, there was a reflection (for want of a better word)... Purely for my own edification, what exactly is that 'reflection', then, Astro0? Is it some sort of artifact produced by the CCD array somehow? -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

QUOTE (Stu @ Nov 12 2010, 02:06 AM) It's been a long road... getting from there to here... I find something so compelling about that "Tracks" image. From A afarensis to robots on Mars. To think of those early homonids and the vast future before them, how little they could have imagined about walking on the moon or roving on other planets. The image really underscores the stunning acceleration of human achievement: 450 years since the Copernican model of the universe, 150 years since Darwin explained the diversity of life, 50 years since we tackled the void of space... Makes you wonder what we could accomplish, not in the next 100 or 1000 years, but in the next 10 or 20. Inspiring. You might even consider adding POLAND, 395 million years ago to the left of your image! (Sorry for going off-topic, but I simply had to comment on Stu's fantastic image.) Back to the subject at hand... hopefully not a stupid question: are those stars or camera artifacts (dust?) in the transit image? |

While not Astro0, I hope neither mind my jumping in
....It is an internal reflection off either one of the three lens elements, the sapphire protective 'cover', or the back of the neutral density filter. If I had to guess which I'd say it's a reflection off the front sapphire cover and again off the inside of the ND filter. Little more than a hand-waving guess though from taking a handful of pictures over the years through welding filters with similar kinds of reflections in some shots  !That help at all? -- Pertinax |

Ah.
No. After what happened to the last Beagle sent into space by a Brit, I thought it best not to. -------------------- |

QUOTE (Den @ Nov 12 2010, 09:17 AM) I wonder how rover drivers determined that it was safe to cross this crater? I'd say almost 7 years driving experience at Meridiani! They've driven through old filled craters before. I agree it's not obvious, though, that it wasn't filled with Purgatory-style dust. |

That little crater was extremely shallow, so it presented far less of an obstacle than the zillion drifts that have been crossed in the last 2 years.
