Whatever eyepiece you're using at the time is your finder eyepiece. ... 152MN is 4.4, so, unlike telescopes with much longer ?-ratios, you're able to use low magnification (27.4 X, 2.3° with the 25 mm PlЖssl eyepiece) which produces bright images and wide fields of view for those dim galaxies, nebulae, and very large star clusters, but the ASTELE? ...

The multiscale analysis of heterogeneous structures is actually an important and effective tool of mathematical modeling in physics, technique and biology. ... The special year will extend the existing cooperation between French and Russian researchers in the multiscale analysis and in mathematical modeling in hemodynamics, taking into consideration the mass transport, coagulation, fluid-structure interaction and other aspects. ...

... Figure 1a illustrates the summary diagram (2 log L, log S ) based on the field intensity contour lines for 7 active regions plotted at 200 G steps in the range of 2200­400 G. One can see that the relationship under discussion is well represented by two straight lines, one corresponding to the log S range from 2 to 7.2 and another, from 7.2 to 9. ... Then, we plotted 2 log L versus log S for all field lines of a given intensity, no matter which sunspot or sunspot group they belonged to. ...

... The circumnuclear GASEOUS disks are often decoupled from the circumnuclear stellar disks and are even stronger inclined to the outer disk planes; in fact, we have found a considerable `population' of inner polar rings. Inner gas polar rings are found as in spiral galaxies with the massive outer gas disks co-planar to the main symmetry planes (e.g. NGC 2841, Sil'chenko et al. 1997, and NGC 7217, Sil'chenko & Afanasiev 2000) as well in many lenticular galaxies (Fig. ...

RUSSIAN . The Centre for Astronomical Data (CAD) of the Institute of Astronomy (INASAN) of the Russian Academy of Sciences was established in 1980 as a branch regional center of the Centre de Donnes Stellaire (CDS) with the purpose of astronomical data dissemination among Soviet and Eastern Europe astronomers and for providing the CDS with Soviet machine readable astronomical catalogues. The CAD archive is based on astronomical catalogues received from Strasbourg since 1980. ...
