Why we "waste" money on NASA research ...
Originally posted by Linked article:
As a researcher at NASA's Jet Propulsion Laboratory, Jim Lux works on technology designed to track distant planets.
"NASA has a long history; we do remote sensing," Lux said. "We are used to detecting small motions from a long way away."
But he also heads up a project called "FINDER."
"With Finder, what we are doing is we are using the same techniques to look for very small motions from your heartbeat at a somewhat shorter distance," Lux said. ... FINDER stands for "Finding Individuals for Disasters and Emergency Response." It fits into a suitcase and can detect when someone is buried alive under collapsed buildings ... by sending out a radar signal.

| I read about that gadget. It's already saved lives. |

Interesting development for astrophotographers. Looks like Canon may be readying a full-frame camera optimized for astrophotography - see here.

Nikon already has the D810a...I'm surprised by the growing demand in this specialized field. |

In normal DSLR's the INfrared block filter removes many of the most
Important wavelengths that deep space objects such as nebula emit. You can modify any dslr by removing the IR filter from the sensor, but this usually leaves it unusable for daytime photography. |

I would have put "R.T.F.M." |

| That's their "crash pad". Their launches are conventional land launches. It's an amazing company. |

| Yes, and Venus has been incredibly bright at the moment. It's high up after sunset - a very nice planet to view at the moment, and more so now that it's a few degrees from Jupiter. |

It's been raining a lot here, but I could see Jupiter & Venus this evening.
I'm hoping to get to photograph the rocket launch coming up around the 26th at Cape Canaveral. I don't know if I will travel up that way, or just shoot it from here if visibility is good. |

| Aurora alert! Just FYI. Could be good viewing tonight although I think last night was the height. |

Apparently last night was good... I looked around 10:30 PM and saw nothing at all, but later seems to have been much better. Still good possibilities for tonight, though!

Your highest chance is at local midnight as you are standing inline with the solar winds... |

It was cloudy here Saturday night for the big conjunction.
I did get to see the Sunday show, along with a nice row of thunderstorms off the Fl coast.
The comet lander awakening is great news, and I see that they just funded the mission for most of another year too.
No aurora here, too far south, but if we see anything I will post an update.
Good one  kirbic. Yeah, we must be getting old to remember that line.

Just wanted to post this cool event:

| Very cool -- what length lens did you use for that? |

1540mm, equivalent to 2310mm. :) Orion Apex 127 telescope with my camera mounted on the T-thread. |

| I thought so ... about six times what my camera can reach unaided. |

Clouded out here this evening... no surprise there, LOL.

| I heard an astrophysicist the other day who remarked "There are a hundred billion stars in the galaxy, and a hundred billion galaxies in the known universe -- in fact, a hundred billion is the only number you need to remember in cosmology ... even the universe is a hundred billion years old -- in dog years." |

I usually just wave my hand and refer vaguely to "Saganesque quantities" and that's close enough!
