Complex Teleescope Making innovations that includes chosen Articles from the Maksutov Circulars relies upon The Massutov Circulars that have been edited over a interval of 21 years through Allan waterproof coat and allotted to Maksutov membership individuals. The membership used to be initially geared up to make a mass buy of customized molded Maksutov corrector blanks however it quickly grew to become obvious publication was once had to percentage details on optics and useful glass operating to shut tolerances. finally, approximately 2 hundred versions of the Circulars have been disbursed to contributors. From this mass of fabric three hundred+ web page books have emerged which describe a variety of matters of curiosity to the person that has made a telescope and desires to benefit extra approximately this interesting hobby.

3, heater the and the was placed 20 mm above the bottom of one compartment divided the test section, and cooler was near the water surface in the other compartment. This configuration was useful enhanced global natural and maintained steady temperature field. convection The simultaneous measurement system is shown in Fig. 4. Two beams of an argon-ion LDV were incident in the normal direction to the axis of the electric heater in order to reduce fluctuations of the measurement volume or disappearance of the intersecting point caused by refractive index change of the fluid due to turbulent natural convection or thermal plume.
The beam intensity was determined to be so small that no saturation might occur. 39 g/m 3 . Simultaneous Measurement of Temperature and Velocity The velocity measurements used Mie scattered light from SiC particles, while the temperature was estimated from fluorescence of Rhodamine thermocouple. B or electromotive force Photograph 2 shows of orange the chromel-alumel liquid for the fluorescence and green particles for Mie scattering, where large polystyrene particles -100 pm in diameter) were used to exaggerate the Mie scattering effect.
4) The correlations of temperature and velocity measured by the fluorescence describe strong relation than those measured by the thermocouple, the correlation relation. and where this fluorescence technique the thermocouple can can hardly detect detect the Authors would like to thank Mr. Toshihiro Yamamoto, University for his assistance in the experiment.
