Very weird
I knew my school once had an astronomy club before, and I know that the astronomy club doesn't exist anymore now. So I knew those facts already half a year ago. But last Friday, noon break was extended(just that day) for some unknown reason, so I had extra free time, and I explored school. Here's what I found out: My school once tried to built an obsevatory and ran out of money after building the obsevatory, and cannot afford a telescope, this is the first part that is weird, how come they had the money to build an obsevatory but can't afford a telescope? Because they can't afford a telescope, they turned the obsevatory into something called a 'Stary Sky Classroom' and it was closed before I entered middle school so I don't know what is in it. At the entrance of the obsevatory, in the staircases, everything changed, the whole part of the staircase has turned into a giant 3D poster large planet models hang on the roof and the wall were filled with huge star maps, astronomy facts, Miesser charts and pictures of famous astronomers like Kepler and Hubble. There were also some other equipments like what they call a 'Celestial scale'. The whole place was very impressive, like a mini astro museum. I stayed there for a long time and felt very satisfied. The 'Stary Sky Classroom' is closed so I still don't know anything about it although it cloud be more satisfying. But you can see that the place is old, the equipments were filled with dust and some wall papers on the roof are falling. Here's the second part that is weird, WHY WOULD THEY CLOSE IT? And what if I tell you, that I just found two other mini museums like that in my school, one of it is even more satisfying than the 'Astro Staircase', which must costs lots of money. But they all have something in common, all locked and old. It's like discovering an ancient empire that is once flourishing but has withered away by now, making people quite sad. Very weird, I don't know WHY. Mabye nobody is interested in astronomy in my school so it's not necessary to open it. Like what@XRaySpex said,'pity those who never look up'

振旺S50的镜头都如何保养维护?
1振旺S50的镜头都如何保养维护?2第一次不知道嘴吹了镜头,然后用清洗液喷了镜头,然后用清洁布擦拭了镜头,然后留下了一些擦拭痕迹,第二次又喷了镜头又擦拭了一下,但是痕迹减少了,平常状态下看不到异常,强光下有类似指纹一样的擦拭痕迹,该怎么办?如何处理,是否有影响?以后都需要什么工具维护保养。 清洁液和清洁布用的是这种。

某东信达小黑售假问题
客服说商家没有售假嫌疑,太离谱了。。。客服明确回复:“包装箱上有的,产品上没有的”,**证明镜筒本身缺失正品应有的激光标识**,这与信达正品特征不符。根据信达官方声明,所有正品小黑均需具备镜筒激光刻印(官网可查防伪说明)。现收到无刻印产品,涉嫌售假或翻新机。目前维权思路中断。

New SuperNova is happening now
NEW SUPERNOVA The coordinates for V462 Lupi (also known as Nova Lupi 2025) are: - Right Ascension (RA): 15h 08m 03.3s - Declination (Dec): –40° 08′ 29.6″ (J2000) It’s currently lighting up the Lupus constellation and has brightened significantly—reaching around magnitude 5.6 by late June 2025, making it visible to the naked eye under dark skies. Quite the cosmic show! Normally it's a magnitude 22.4 One 300second lum exposure

3D Accessories for Seestar S50 : Download, Print, Share!
Hello everyone! As promised, at the bottom of the article you'll find two links to download the STL files for the Seestar S50 accessories. The long linkcorresponds to my drive, and the short link leads to the same place, but with a shortened URL. As I said in my first post, these files are royalty-free: you can print them for your own use, and even sell the printed parts to people whodon't own a 3D printer. The aim is to help each other, not to make a business out of it. The main directory of my drive, entitled “ZWO Seestar S50”, contains 7 sub-directories. In each of them, you'll find 3 files:- An .stl file, for use with cutting software (e.g. PrusaSlicer).- An .obj file (text format describing the geometry of a 3D object: vertices, edges, faces), compatible with software such as Blender (free), Autodesk Maya (paid) or SketchUp, among others. - A screenshot showing the appearance of the STL file. List of available accessories:- Cylindrical light protection tube- Star refraction 6 tips- Star refraction 4 tips- Star refraction 3 tips- Conical light protection- Bahtinov mask- Lens cap For printing, I used a Prusa MK4S, with a layer height of 0.15 mm, and PLA filament. Here are the two links to the stl files: Link 1:https://drive.google.com/drive/folders/1uZj6tMKM9m2EoekVSPNTEdk_TxhNYIdw?usp=sharing Link 2: https://shorturl.at/S76pt I also have other models, allowing the use of 2" filters to be mounted on a filter holder and an anti-light tube. However, as I don't own any2" filters, I can't guarantee compatibility.If anyone is interested, I can create a “proto” directory on my drive to share these files as they stand. Happy printing, and good evenings under the stars! LaTana06
