Deteccion de exoplaneta Wasp77Ab mediante curva de luz de su estrella BD 07 436Ab

Primer intento más o menos exitoso de detección de exoplaneta wasp77Ab mediante tránsito de su estrella, hay que mejorar las técnicas y suavizar la curva pero me quedo impresionado que con un seestar S50 se pueda hacer fotometría más o menos decente con un nivel de conocimiento muy amateur Son unas 3 horas de datos430 fotogramas de 20".Ecualizador S50 modoBortle 6,5NINA aporta datos del transitoSIRIL procesamiento, astrometria, fotometría y gráficos Más o menos resumido Lo primero es buscar en el secuenciador avanzado de NINA el plugin exoplanet object container para planificar el evento de esa nochePlanificas un plan para observar la estrella que va a tener un tránsito seguramente la tendrás que poner manualmente en objetos personalizados del s50El tiempo a observar te lo da NINA y le sumas antes y después 30 minutosUna vez que tengas los sub de 20" los procesas en SIRIL y le haces la fotometría de dicha estrella, en el tutorial de siril viene como hacerlo y tras prueba y error consigues una curva de luz más o menos decente teniendo en cuenta que es un S50

Earth

We can imagine that everything we perceive, learn, and think is false. We don’t even know what is true—what in this world is real? Perhaps the language we speak now is also false, for its origin can never be traced. Even if you look back to when people first created language, they couldn’t prove why they did it—because no one knows. When you step into space, you’ll realize there are always greater beings beyond humans and broader skies beyond the heavens. Picture 1: This is Earth seen from the Moon [380,000 kilometers away from Earth]. Earth is 49 times the size of the Moon, and one Earth could hold about 20 Moons, yet Earth appears tiny when viewed from the Moon. Picture 2: This is Earth seen from Voyager 1—a mere small dot. Picture 1 doesn’t reveal much, but when you see Picture 2, you’ll understand how insignificant we are in the vast universe. This small dot is our Earth, and it’s home to 8 billion humans—who are not even a grain of dust in the cosmos. mmexport176…9_1196.mp4 You’ll realize how insignificant we are—even overwhelmed by a sense of awe and fear, known as the Overview Effect. The universe is filled with countless planets; the ones we’re most familiar with (and relatively close to Earth) include Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Yet among them, only the Moon has been accessible for human landing. As of November 2025, the Moon remains the only celestial body where humans have successfully landed. Between 1969 and 1972, NASA’s Apollo program completed 6 crewed lunar missions, sending 11 astronauts to the Moon’s surface. For other planets, only uncrewed probes have landed on Mars and Venus—manned missions are still pending. Mars has been the focus of more exploration: NASA has deployed multiple rovers, and China’s Tianwen-1 also achieved a successful landing. Venus, however, has harsh environmental conditions, limiting the data collected by landers. Mercury, Jupiter, Saturn, Uranus, and Neptune have not been landed on due to inhospitable living conditions or extreme landing challenges.

Using UPS instead of power station for power system？

Background:I’m new to deep-sky astrophotography. My main gear will arrive later this year from China. Since large LiFePO4 power stations cannot be checked in on flights, I’m looking for a local power solution in the US.I noticed that my NAS uses a DC UPS with 12V output, DC input, and USB-C, so I’m wondering whether it can be used to power ASIAIR and my imaging setup. Idea:Connection: Astro gear → ASIAIR → UPS → multiple power banksMy NAS UPS (Ugreen) is rated 12V 10A, 120W max, 43Wh.Voltage and current seem enough for a normal DSO setup. The UPS’s small internal battery isn’t an issue because I have three ~80Wh power banks that can feed the UPS through its DC-in/USB-C port. Main Question:If I use these 3 power banks as the main energy source and let the UPS provide stable 12V output,do I still need to buy a dedicated outdoor power station,or is this UPS-based system stable enough for deep-sky imaging?

论使用UPS与多块充电宝作为供电体系？

背景介绍：纯深空新人，器材买了年底朋友从国内带过来，因专用电源容量过大无法托运，所以正在美东当地找合适的电源。在查询过程中想起来给家里nas供电的ups也是12v dc out口，同时ups配有dc in口和type-c口。鉴于网上没找到相关的话题于是在这里发帖问问各位。ps：一直拖延症不买其实是抠门毛病犯了，国内店小二一度电两千rmb不到，在美国官网给你搞个四五千rmb你爱买不买。连接思路：摄影器材——天文盒子——ups——充电宝（多块）鉴于家里nas配备的绿联ups参数为：12V-10A 120W max 输出，43WH，我就照这个来考虑了（市面上必定有更好参数的）。根据参数，电压电流应该足够撑起一套正常的深空器材，43WH的容量并不重要因为主要电源来自充电宝。那我现有3块约80wh单个的充电宝输出给ups，是否不需要额外购买户外电源来为天文盒子供电。
