Porth, C. Fendt submitted to ApJ We perform axisymmetric relativistic magnetohydrodynamic (MHD) simulations to investigate the acceleration and collimation of jets and outflows from disks around compact objects. The fiducial disk surface (respectively a slow disk wind) is prescribed as boundary condition for the outflow. We apply this technique for the first time in the context of relativistic jets. The strength of this approach is that it allows us to run a parameter study in order to investigate how the accretion disk conditions govern the outflow formation. Our simulations using the PLUTO code run for 500 inner disk rotations and on a physical grid size of 100x200 inner disk radii. In general, we obtain collimated beams of mildly relativistic speed and mass-weighted half-opening angles of 3-7 degrees. When we increase the outflow Poynting flux by injecting an additional disk toroidal field into the inlet, Lorentz factors up to 6 are reached.... O. Porth, C.

The telescope is made from solid brass and has a special clear coating that never requires polishing and will not tarnish. The 12-power Pocket Telescope has two pipes and measures 9 1/2 inches (24 cm) when extended. The optics are high quality multi-coated glass that produce an erect (upright) image through its 17 mm diameter objective lens and large 8 mm diameter eyepiece. The telescope is marked "Stanley London" near the eyepiece. The Premium Hardwood Box is a high quality hinged dark hardwood case with dark green felt lining. The Hardwood Box has hidden brass hinges and a smooth hand rubbed finish. The pocket telescope weighs 3.4 ounces (96 grams) and the premium box weighs 6.1 ounces (173 grams). Feature: Telescope is 7/8-inch (22 mm) in diameter, and 5 5/8 inches (14 cm)...

You can attend one of their star parties and try out other people's eyepieces in your scope before you spend your money. You can judge for yourself what is the best for you. I do not recommend a barlow. Adding more lenses, more pieces of glass, also adds more distortion to your viewing experience. You are much better off adding eyepieces to your collection than you are adding a barlow. If it were me, I would get one in the 8-10mm range and I would get one in the 32-40mm range. Wide field are best. Orion has the best customer service and value for the money. http://www.oriontelescopes.com/ Join a local Astronomical Society or club.
