. The Gemini multi-conjugate adaptive optics system (GeMS) deploys five laser guide stars and up to three natural guide stars, for better-than-Hubble resolution of ~ 90 milli-arcseconds in Ks-band across the field of view of the RSAA-built Gemini South adaptive optics imager (GSAOI). I will present a user s view of observing with this complex instrument, and make recommendations for getting the most out of your GeMS/GSAOI data.

... One of the widely used models of neural network is the multi-layered perceptron [6]. The model network has layers of input and output elements called neurons. ... An input vector is put on the input layer, passes through the hidden layers, and arrives at the output layer. The corresponding output vector is determined by calculation of the neuron activity level for each layer using already known values of neuron activity of the previous layers. ... Training was an iterative process. ...

... Luminous blue variable (LBV) stars are the most massive stars with 40-120 solar masses, which are passing the short stage of evolution losing their hydrogen envelopes before exploding as Supernovae. These are extremely rare objects, only about a dozen of the most massive LBVs are known in the Galaxy. ... In the spectral observations of stars with infrared circular nebulae, found in the Spitzer survey (24 microns), a new LBV star in the Galaxy was discovered. It was named MN112. ...

Если рефрактор длиннофокусный пусть и ахромат то он при равных апертурах несомненно выиграет у зеркально-линзового телескопа. ...

... Пояснение: Поражающая своим великолепным видом в бинокль или небольшой телескоп, поверхность Луны испещрена ударными кратерами. ... Но когда Луна полная, некоторые кратеры кажутся окруженными системами ярких радиальных линий или лучей. На этом подробном снимке полной Луны видны два известных кратера с лучами , Коперник (вверху слева) и Тихо (внизу справа). ... В общем, кратеры с лучами сравнительно молоды, так как их лучи покрывают лунный рельеф . ... SMART-1 спрятал концы в лунную пыль . ...
