Magnification (Power) And Using Eyepieces . ... To determine power in a telescope, divide the focal length of the telescope by the focal length of the eyepiece. By exchanging an eyepiece of one focal length for another, you can increase or decrease the power of the telescope. For example, a 25mm eyepiece used on a telescope with a 1000mm focal length would yield a power of 40x (1000 / 25 = 40) and a 10mm eyepiece used on the same telescope would yield a power of 100x (1000 / 10 = 100). ...

... 640W A survey of ultracompact (UC) Hii regions has been carried out by searching for 6.669-GHz methanol maser emission from a sample of 535 IRAS-selected candidates. A total of 201 candidates exhibit methanol emission. These sources have been used, in conjunction with previously identified UC Hii regions, to provide a base for further studies of such regions. ... Methanol maser and/or radio continuum emission is found in 364 cases towards IRAS-selected regions. ...

... Our main goal was to study the large-scale distribution of the molecular gas in the Serpens region and to understand its relation with the denser gas in the cloud cores, previously studied at high angular resolution. ... The 13CO and C18O(1--0) maps of the centroid velocity show an increasing, smooth gradient in velocity from East to West, which we think may be caused by a global rotation of the Serpens molecular cloud whose rotation axis is roughly aligned in the SN direction. ...

. The Catalogue has been created as a handbook for professional astronomers and experts in other related fields of knowledge. An additional objective is to outline the astronomical knowledge that is required for understanding and usage of the data included in the Catalogue. The Catalogue contains data on 493 potentially hazardous asteroids as of 27 March, 2003 (Minimum Obital Intersecion Distance MOID H .

... These sources are much more likely to be gravitationally lensed by intervening galaxies as compared with sources discovered in surveys in other wavebands. ... The effect of lensing by clusters is then discussed briefly. This is expected to increase the source confusion noise in a Planck survey in the directions of clusters, and could provide information about galaxies with flux densities that are too faint to be detected directly by Planck . ... 2 The properties of galaxy--galaxy lensing . ...

Active Galactic Nuclei (AGN) are ideal sources for multi-wavelength studies as their emission can cover almost 20 orders of magnitude in frequency from the radio to the gamma-ray band. ... I will then briefly illustrate how currently available and forthcoming sky surveys will help in addressing some of the open questions of AGN studies. ... Figure 1 (65kb) . Figure 2 (23kb) . ...

... Even future mission archives tend to concentrate more on what can be extracted out of a proposal or a Guaranteed Time Observation log than the actual extracted science out of the data itself. ... A year later the data is then publicly available. An archive researcher has then to go through a mass of data to find what may be useful without any indication as to what the actual observer's results were while using the data except the proposal, which in most cases is very general. ...

... The DAL is essentially implemented in C++. The design takes the form of a set of abstract classes which provides the fundamental DAL interface. There are currently two implementations (both in C++) of this abstract interface; one is the High Memory Model and the other is the HighLow Memory Model. ... In particular, an understanding of the C++ class hierarchy will lead to more generic algorithms e.g. use BlockT rather than ArrayT if only the BlockT methods are needed. Class Hierarchy . ...

The Canadian Galactic Plane Survey (CGPS) is a major initiative to improve our understanding of physical states and interactions in the Interstellar Medium (ISM) in our Galaxy. In 1995 we set out to create arcminute-resolution images of the major constituents of the ISM. ... Based on the results of the first five years, the CGPS Consortium proposes a Phase 2, designed to probe new questions. ...

... In this paper we present the results of detailed B, V, R, I, and H study of the isolated nearby blue compact dwarf (BCD) galaxy NGC6789. Judging from the literature the observed galaxy has not been resolved into stars up to now. ... The distance of the galaxy, estimated from the tip of the red giant branch (TRGB) is 2.1 Mpc which places NGC6789 close to the Local Group. ...

Electrons with sufficient energy to emit synchrotron X-rays must be accelerated locally to the knots, since their energy loss timescale is short compared with any dynamical timescale associated with fluid motion. ...

... In 1930, Trumpler noticed that linear diameters (LD) of open clusters increase with distance (D) from the Sun. ... Since that time, the interstellar absorption has become one of the best studied factor in astrophysics, and we may hope that current OCL distance scales are free from this LD-D correlation. To verify if this is the case we have chosen several modern OCL distance scales and test them with the same clusters and the same angular diameters that Trumpler had used back in 1930. ...
