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。

smart telescope  用 解星 找出天空天體位置 , 類似  早在 2013 celestron star sense 有 類似 方法 .

WIKI  smart telescope   /  video_astronomy
https://en.wikipedia.org/wiki/Robotic_telescope


A 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

為什麼主流智能望遠鏡沒有「變焦」功能？

大多數智能望遠鏡，例如 Unistellar 的 eVscope 系列和 ZWO 的 Seestar 系列，都是固定焦距的設計。這種設計有其優勢：
1. 光學性能最佳化： 固定焦距的望遠鏡光學設計可以針對一個特定的焦距進行最佳化，確保在整個感測器上的成像品質、像差（aberration）控制和光學性能達到最高水準。
2. 結構簡化： 變焦系統需要多組可移動的鏡片，這會增加光學路徑的複雜性、成本，並可能引入更多像差。對於追求輕巧便攜和操作簡單的智能望遠鏡來說，固定焦距是更理想的選擇。
3. 簡化自動對焦： 智能望遠鏡通常具備自動對焦功能。如果焦距可變，自動對焦系統的設計將變得更加複雜。


現有的「可變 FOV」解決方案
1.影像拼接（Mosaic Imaging）
2. 減焦鏡或增倍鏡
3. 數位變焦（Digital Zoom）

為何沒有真正的光學變焦智能望遠鏡？

雖然技術上可能實現，但將光學變焦加入智能望遠鏡會增加許多設計上的挑戰，例如：

    成本大幅增加

    光學複雜性，可能影響成像品質

    體積與重量增加，犧牲便攜性

    自動對焦與校準難度提高

中國同好對 EAA 是 Electronically Assisted Astronomy 一些心得說法 

https://mp.weixin.qq.com/s/5gP5qI86uKA3DPGbM2MHQg

Are Smart Telescopes Taking Over Astrophotography?  

How smart telescopes started (Stellina, eVscope) and why Seestar changed everything
The software revolution: EQ mode, mosaics, stacking, and app-based processing
Smart scopes vs “smart rigs” (ASIAIR, N.I.N.A., plate solving, autofocus)
Why people keep asking for bigger “Pro” smart telescopes
The hard limit: you can’t download aperture (light collection + diffraction limit)
Why bigger smart telescopes get heavy fast (optics, mechanics, cooling, battery)
The price problem and upgradability risks in high-end all-in-ones
The “soul” of the hobby: building rigs, learning the process, and visual observing
