A spherical primary can be corrected for Spherical Aberration,Coma, and Astigmatism with a Mangin -Relay lens Combo (ATMoB member Don Dilworth design) or with a modified Abbe Reflector-Corrector - requires spacing, tilt, and decenter adjustments. Another way is with a strongly Hyperbolic secondary -very tiny FOV . ... Copyright (c) Amateur Telescope Makers of Boston, Inc. ...

Porting to a new machine or operating system ordinarily requires updating the ./machines directory and the ./compilers directories in order to define the build environment and autoconfigure means. You will probably have to modify the ntp_machines.h file and "l_stdlib.h" files as well. ... Always define a system identifier for any new system added to the machines directory. ... This file is included by the "ntp_types.h" file and should always be placed first after the <> defines. ...

... We demonstrate through numerical simulations that model parameters estimated with our technique are essentially bias-free, even when the average number of counts per bin is 1. ... The IW technique avoids such biases by estimating through successive iterations, where for each iteration, j, , and the best-fit parameters are determined by minimization of . ... In our sample, we find that the minimum values and best-fit parameters converge after about 6 iterations. ...

... Planets . ... Stars . Exoplanets . ... Most exoplanets so far discovered fall into the category of тАШhot JupitersтАЩ, these are giant planets orbiting very close to their parent star. ... Note that we have discovered so many hot Jupiters because they are the easiest type of planet to find, they are not necessarily particularly common in the galaxy. ... Subsequently several similar hot and€а fuzzy worlds have been discovered the same way, proving this that this planet is not a one-off oddball. ...

. I measured my limiting magnitude on this picture at about Mag 18.9. I also did some photometry near for the SN positon, and I found a star liked object at about Mag 17.6. I think this object is 1999br. This image is deconvoluted, but I measured the magnitude pre-deconvulution. Kereszty Zsolt . Hungary, Miskolc . Back to Bright Supernovae .

Space vehicle "Apollo-11". ... The main aim is to carry the cosmonauts on the Moon, there are also pilotless flights and the spacemen's flights around the Earth, the "Apollo" modification were used to carry the cosmonauts on the orbit station 'Skylab' and joined with the Soviet spaceship "Sojus-19" on the programme APAS . ... The first was N. Armstrong in "Apollo-11", E. Aldrin (1969) ( см. D. Irvin on the Moon ). The maximum time of the being in the Moon is 75 hours ("Apollo-17", 1972). ...

. Comment on J0126-0123 . No detection: this object has been studied with the Molonglo telescope at 408 MHz (Schilizzi & McAdam 1975) as a source with a size between 2 and 5 . It is near an Abell cluster (Owen & Ledlow 1997). The data could be confused with a strong radio source (3C 40) identified with a pair of galaxies at z=0.018, 170" from our field center.
