Аннотация: Some series of CCD observations are performed in BVRI filters for the M67 (NGC 2682) cluster to examine the photometric system of the Kyiv internet telescope. The registration system includes the telescope Celestron CGE-1400, Celestron f/6.3 Reducer/Corrector (#94175), automatic turret with a set of UBVRI filters and CCD camera Rolera MGi. The field of view for the system is 10.62′ by 10.62′. Frame processing is executed with the use of the MIDAS/ROMAFOT package. Reduction coefficients of the instrumental photometric system are determined relative to BVRI system. Our results of observation processing agree with the results of other researchers at to the distance module for the M67 cluster and give V – Mv = 9.63m. The rms errors for one determination of stellar magnitude for different wavebands lie in the range 0.02—0.12m. The errors for determining the equatorial coordinates in the TYCHO-2 catalogue system are ±0.1′′. |
