... December 21, 1997 . ... Advantages are briefly discussed of gaining in spectral resolution, which is accompanied by losses in signal level, as compared with the attempts to improve the accuracy of measurement of line parameters by means of rising the S/N ratio alone with increasing the exposure time. To partially solve the problem of observations of faint objects at the BTA a new design echelle spectrometer is proposed. high resolution spectroscopy . ...

The technical memorandum: A Kernel Programming Interface for Precision Time Signals (PostScript) describes a proposed programming interface for external precision time signals, such as the pulse-per-second (PPS) signal generated by some radio clocks and cesium oscillators. ... The hardware to do this requires only a serial port and a modem control lead, such as the data carrier detect (DCD) lead, which can be driven by an external source via a level converter/pulse generator. ...

Solar High Resolution Studies . ... Dynamic magnetic fields continuously emerging from the solar interior on a wide range of scales, and their interaction with convectively-driven plasma flows, play a major role in shaping the whole solar atmosphere. Even though the fundamental spatial scales of turbulence and magnetic fields are still unreachable with present-day telescopes, polarimetric observations at the highest possible resolution will allow important insights into these issues. ...

Astrophotography Forum Message . ... The resolution of a CCD camera does not depend on the number of pixels in the camera, rather it depends on the size of the pixels making up the chip and the focal length of the lens forming the image. ... A larger chip made from the same substrate will have identical pixel sizes, just more of them. ... With a fixed focal length telescope we don't have that luxury, in which case smaller pixel size rather than larger chip size is the only way to increase resolution. ...
