古人观星会是什么样子

怪不得古代的能写出关于星空很美的句子，那会中国应该全部都是现在的“国际暗夜区”标准，李白肯定是经常看见银河，才能写出疑是银河落九天，屈原肯定是经常看见天狼星才能写举长矢兮射天狼，现在抬头看星空有时候猎户座都看不清楚。不过和古人看的是同一片天空也是很奇妙的一件事。

求问，mini盒子支持艾顿smarteqpro+赤道仪吗？

想用杀马特赤道仪租一套便携打野，听说盒子有一些赤道仪不支持，有没有大佬知道这款可以用吗？

深空摄影

深空叠加处理还是机器拍摄生成？

放两幅图，一张是机器的深空叠加处理，三百多张，耗时半个多小时；一张是直接拍摄生成的，拍摄时长半小时。各位看看哪个更好？

Seestar S50 – Moon centered on screen but shifted in timelapse video during lunar eclipse?

Hi everyone, I recorded last night’s lunar eclipse from New Caledonia with my Seestar S50 using the timelapse mode. During the whole observation I was monitoring the image on my iPad, and the Moon always appeared centered on the screen. When the Moon turned red during totality, I manually adjusted the gain and exposure and re-centered the Moon to make sure it stayed in the middle of the frame. At one point, when the Moon became very dark, the Seestar temporarily lost it. After increasing the gain, the Moon became visible again and I re-centered it. However, when I look at the final timelapse video, the Moon is clearly shifted and even partially out of the frame during the red phase. This confuses me because I clearly remember that the Moon was perfectly centered on my screen at that moment (see the attached images). To help explain the situation, I am attaching two images: • two frames from the recording where the Moon appears centered • one frame from the red phase where the Moon appears shifted My question is: Is it possible that the Seestar processes or re-aligns frames when generating the timelapse and changes the framing? I would really appreciate your insights if you have experienced something similar with the Seestar S50. screencast from my screen during the recording screenshot from the final Timelapse video :
