  • Dec 13, 2013 · A team of physicists has provided some of the clearest evidence yet that our Universe could be just one big projection. In 1997, theoretical physicist Juan Maldacena proposed that an audacious model of the Universe in which gravity arises from infinitesimally thin, vibrating strings could be reinterpreted in terms of well-established physics.
  • Lightman: I wanted to start by asking you some questions about your childhood and early background. Could you tell me a little bit about your parents? De Vaucouleurs: I was born and educated in Paris, France. My parents were divorced and I was raised by my mother, Raymonde, a talented painter, who gave me strong moral principles. She died in 1987, aged 94. I read my first book in astronomy ...
  • It puts hatred and judgement into our hearts instead of love. Those in power have much to gain from populations fighting each other. We keep ourselves in chains by judging one another. We do their work of oppression for them. It is just that we need to realize that peace and unity is the way to real power.
  • At unity gain (G=139,O=50) I got Ha images that my software could recognize and stack. And thanks to @Ciraxis input, I upped the dither from 15 pixels to 25 pixels (which didn't increase the settling time all that much) and almost all of the discernible walking noise is gone.
For a Canon 6D DSLR, why not use "Unity Gain" = ISO 800, for AP. If I use any ISO above Unity Gain, then I lose Dynamic Range - more high end pixels saturate = bad. If I use any ISO below Unity Gain, then I lose image detail - more low end pixels are noisier = bad. The ISO for Unity Gain is not subjective. You must expose long enough to ...

Intention¶. So you installed GIMP on your computer, congratulations! GIMP is a very powerful image manipulation software, but don’t let that intimidate you. Even if you don’t have time to learn advanced computer graphics, GIMP can still be a very useful and handy tool for quick image modifications. I collected 17 luminance frames, 8 red, 6 green, and 7 blue, each 3-minutes long at unity gain. I had 8 of each of the RGB frames at first, but as M51 sunk toward the horizon, the atmosphere was mushier there, so the guiding wasn't as good. This led to streaky or bloated stars, so I deleted those frames.
Jul 19, 2010 · One of the most iconic images in modern astrophotography is the famous "Pillars of Creation" in the Eagle Nebula. The tops of the clouds, with their Q-tip structures, x-ray radiation, and compact shapes are also deemed to be stellar nurseries, where standard theories meet colorful pictures.

Flatbuffers in Unity – A 40x Gain (extrawurst.github.io) 6 points by todsacerdoti posted 2 days ago The U.S. Internet Is Being Starved of Its Potential (eff.org) The 100 value on the ASCOM driver is not equivalent to the 100 unity gain value. There are two explanations below for your reference: 1) Gain setting 0: this allows to use the full well capacity completely and expose longer and with lower risk of saturating stars respectively. 2) Gain setting 100: this allows to take advantage of low readout noise.
