The Study of Open Cluster by Small Telescope

Abstract

The study of open cluster by small telescope in the work is the calculation of the distance and the age of an open cluster M35. It was observed by the digital DSLR via the 150 millimeters’ diameter telescope at Regional Observatory for the Public, Cha Cheong Sao on 19th January 2017 and was analyzed the intensity to constructed an H-R Diagram. The distance and the age analysis show that the errors are less than 10%.
