Someone on Facebook replied to a post of mine comparing S30pro images to s50 of M51. He suggested I make a folder named mosaic_m51 on the S30pro and put the "lights" from the S30pro and the s50 in it. Then run deep sky stacker through the app. So I did this. I had my doubts. First of all about 16 files had the same name so I let windows rename the s50 dupes( just dupe names). I ran the stacker and, of course, 1/2 the files were rejected. And the stack looked awful. This doesn't work. Did he mean DSS in windows? Or DSS not by ZWO? Or was this just a facebook punk that was full of BS?

I am currently at 2/3 complete of the MGS. I'm 5 months in, I can't imagine doing this in 1 night!

C/2026 a1 (maps) is almost here! I made a little paragraph on what I researched note I'm not proffesional this is just from my research: “c/2026 a1 (maps) has a good probability of becoming significant and brighter then Venus a few after perhillion. However many sungrazers dont always survive perhillion, here’s what we know; this comet is around 0.4km (400 meters) of a nucleus. Its distance to the sun during perhillion is around 0.005732 AU away (AU = Astronomical Units, where 1 AU = the sun distance to the earth), where a comet called “c/2011 w3 (lovejoy)” came around a similar distance of 0.0055~AU, with a similar nucleus size(100-500m) and survived but partially fragmented later on. So the comet has a chance of either completely disintegrating, partially fragmenting, or staying intact(highest chance is fragmenting). Itll be low on the horizon as well close to the sun, favored south hemisphere. Next the tail. If it stays intact and survives, based on geometric data, orbital plane alignment to earth and overall angular calculation, the comet will most likely have a pencil, straight narrow tail like comet lovejoy 2011 did. However, if it does fragment, this would cause multiple pieces of dust production which can create multiple pencils at different angles, which is similar to comet c/2006 p1 (mcnaught), a comet who had a fan striated dust tail. additional info, this comet reaches perhillion April 4,2026, and was discovered on January 13th, 2026, from “AMACS1 Observatory, Atacama Desert, Chile”, discovers being Alain Maury, Daniel Parrott, Florian Signoret (MAPS team). It is a kreutz sungrazer family group, comets that go very close to the sun, with the origin being a large comet who broke into many small pieces creating all these comets. this comets orbital period is estimated to be about 1,700~ years, with inclination being ~144.5 degrees. However, comet magnitude is uncertain and comet tail morphology is uncertain as factors such as dust production, solar wind interaction, particles sizes, rotation, etc. arent really easily predictable. Comet behavior is also unpredictable and wild. I wrote this conclusion 10:52 pm, March 30, 2026.”

Tonight, I set Seestar to shoot Deep Sky objects again. But after AI denoise of the first shot... ...these strange specks appeared. I tried to wipe the lens, it didn't help. Give me some advice, please

I've googled how to stack the raw video on the Seestar S50, but when I pull up my video of the moon, I don't see the option to stack. Am I missing something? Video is under 5 minutes

If so, what is your experience with them and do they function well. Thanks!

I am new and looking for free easy ways to plan what I want to see you tonight. I've stumbled across TimeAndDate.com's "night sky" Which seems to be fairly good, at least to my amateur eye. But I was wondering if anybody knew any other resources out there I could turn to? For context: Right now I'm using a Seestar S50 I would be willing to pay for a good site or good app, but I really don't wanna pay for a bunch of bad ones. Any advice would be greatly appreciated.

⭐ 1. Formación: de nebulosa a protoestrella 🔹 Nebulosa (nube molecular) Gas (hidrógeno principalmente) + polvo.Temperaturas muy bajas (~10–30 K).La gravedad inicia el colapso (a veces por choques o supernovas cercanas). 👉 Ejemplo: Nebulosa de Orión. 🔹 Protoestrella El material cae hacia el centro → aumenta la temperatura.Se forma un núcleo denso y caliente.Aún no hay fusión nuclear estable.Puede haber discos protoplanetarios alrededor. ⭐ 2. Fase estable: Secuencia principal (equilibrio hidrostático) Cuando el núcleo alcanza ~10 millones K. Se activa la fusión nuclear (hidrógeno → helio). 🔬 Qué ocurre exactamente: La gravedad intenta colapsar la estrella mientras que la energía de la fusión empuja hacia fuera, esto crea un equilibrio hidrostático. 🔹 Tipos de fusión: Estrellas como el Sol → cadena protón-protón.Estrellas masivas → ciclo CNO (más eficiente). 🔹 Duración: Depende de la masa. Masivas → millones de años.Pequeñas → miles de millones (o más). ⭐ 3. Fin del hidrógeno: salida de la secuencia principal. Cuando el hidrógeno del núcleo se agota: 🔹 Cambios internos: El núcleo (ahora de helio) se contrae.Aumenta la temperatura.El hidrógeno empieza a fusionarse en una capa alrededor del núcleo. 🔹 Resultado visible: La estrella se expande enormemente.Se enfría la superficie → color rojo. 👉 Se convierte en gigante roja. 🔀 4. Evolución según la masa 🌟 A) Estrellas de baja/media masa (≤ 8 masas solares) 🔹 Fusión de helio: Cuando el núcleo alcanza ~100 millones K: Helio → carbono y oxígeno. 🔹 Fase final: El núcleo ya no puede fusionar más (no alcanza temperaturas suficientes).La estrella expulsa sus capas externas. 👉 Forma una nebulosa planetaria. 🔹 Remanente: Núcleo compacto → enana blanca.Muy densa (masa solar en tamaño de la Tierra).Sin fusión → se enfría lentamente durante miles de millones de años. 🌟 B) Estrellas masivas (> 8 masas solares) Aquí el proceso es mucho más extremo: 🔹 Fusión en cadena (tipo “cebolla”) Se forman capas donde se fusionan distintos elementos: H → HeHe → CC → NeNe → OO → SiSi → Fe (hierro) 🔹 Punto crítico: El hierro no produce energía al fusionarse.El núcleo colapsa en segundos. 💥 5. Explosión: Supernova. Rebote del núcleo + ondas de choque.Se expulsan las capas externas violentamente.Se crean elementos pesados (oro, uranio…). ⭐ 6. Remanentes finales Dependen de la masa del núcleo: 🔹 Estrella de neutrones Núcleo ultradenso (protones + electrones → neutrones).1 cucharadita ≈ miles de millones de toneladas. 🔹 Agujero negro Si la masa es enorme la gravedad vence completamente.Se forma una región de la que ni la luz escapa.
