如果想进一步了解不同焦比的光学区别可以阅读CFF官网由CFF首席折射光学工程师Pal Gyulai撰写的文章: http://cfftelescopes.eu/optical-design CFF的全部APO均由Pal Gyulai一人亲自研磨组装,因此产能十分有限,在全世界基本没有代理商,这也是CFF国内知名度较低的一个原因。 ... CFF 102mm F10 APO, 图源:CFF官网 最...
简介: This book is an attempt to demystify the activities of a celestial object such as the sun. Building on simple logic, the contents begin with measurements of the gross properties of the sun like size (volume) and mass from which the avera...
First, they used the telescopes to measure the angular size of the sunspot. This involved comparing the spot's apparent size to the known angular size of the Sun. Next, they employed a bit of trigonometry to convert the an...
