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. ...

Analysis of polar motion variations from 170-yearobservation series . ... Pulkovo Observatory, St. Petersburg, Russia Abstract: . This work is devoted to investigation of low frequency variations in Polar motion (PM). It has been shown that the main PM features can be effectively investigated using not only time series of the Pole coordinates, but also using series of latitude variations obtained from observations at one observatory. ... polar motion, harmonic, Chandler wobble. ...

... In electron-positron colliders, effect of the lattice modification by opposing bunch focusing on the equilibrium radiation emittance is important at high values of the space charge parameter, so one should correctly evaluate this dynamic radiation emittance of the weak beam, which may differ a lot from the nominal emittance, already in the linear beam-beam force model. ... The linearized beam-beam force is equivalent to focusing insertion in linear lattice of the collider. ...
