SEESTAR 星圖比對與 WCS 解算
為了實現精確的定位與追蹤，Seestar S50 會將實際觀測到的星點與內建的星圖進行比對，透過 Plate Solving 技術解算出影像的世界座標系統（WCS）。這樣可以確保望遠鏡的定位精度，即使在無需手動對準的情況下，也能精確捕捉目標天體。

成像圈（Image Circle）
RASA 6 吋的標準成像圈（Image Circle）約為 16 mm，最大可用視場（Usable Field）約為 22 mm。這個大小剛好對應 1 吋或 4/3 吋左右的感光元件。
41mm 或是 43mm 是什麼？：大約 43 mm 的對角線尺寸是標準的全片幅（Full Frame）相機感光元件規格。Celestron 旗下口徑較大的專業級鏡筒（例如 RASA 11 吋）其成像圈才能達到約 42 至 43 mm，支援全片幅相機

https://en.wikipedia.org/wiki/Astrometric_solving WIKI smart telescope / video_astronomy
https://en.wikipedia.org/wiki/Robotic_telescopeA newer introduction to the consumer market are smart telescopes. They are self contained robotic astronomical imaging devices that combine a small (50mm to 114mm in diameter) telescope and mount with pre-packaged software designed for astrophotography of deep-sky objects.[8][9][10] They use GPS data and automatic star pattern recognition (plate solving) to find out where they are pointed. They have no optical system that allows the user to directly view astronomical objects and instead send an image captured over time via image stacking to a built in digital display (usually shaped like a conventional eyepiece), or to a smartphone or tablet. They come with a database of pre-programmed objects, per-determined imaging routines, and Mobile app software that allows the end user to begin astrophotography as soon as the telescope is set up. They can be operated remotely and are able to collect a series of images unattended. The design of the imaging system, combined with relatively small optics, are not optimal for imaging planets or the Moon.[11] Examples include models from the French companies Unistellar and Vaonis
