望远镜 ota dsc什么意思

望远镜 ota dsc什么意思？谢谢

dsc是单反吧

看我帖子里有

OTA(Optical Tube Assembly）管状光学组件。意思就是镜筒+镜片。调焦座跟镜筒是一体的，也算是镜筒的一部分。

DSC，digital setting circle，在国外比较流行，国内翻译为数字定位圈，但很少见。简单来说就是数字显示当前高度角和方位角

Introducing SkEye
SkEye aims to be an advanced planetarium for Android.

The features are geared towards the experienced visual observer, though the interface tries to keep it simple for the beginner.

If you are beginning with astronomy, SkEye can help you identify bright stars, planets and constellations simply by pointing your phone / tablet in their direction. This is a great way to familiarize yourself with the sky.

Virtual DSC
A unique feature of SkEye is that you can strap your phone to a telescope (or a pair of binoculars) to get a PUSHTO guide, without additional equipment! You only need to follow a simple alignment procedure. Find out more about it in the Documentation section.
