Voy a dejar aclimatando afuera asi a las 23 por ahi, me meto un Júpiter con la gran mancha roja de carnaval... Si hay buen seeing quiza hasta haga un video #telescopio #astronomía #jupiter #grs #refractor

$Telescopio refractor$

Ayer en el Observatorio del IAVA con el hermoso refractor portátil para ver Saturno, se veía hermoso. Tremendo instrumento. #astronomy #astronomia #telescopio #telescope #refractor #montevideo

$Yo parado junto al telescopio refractor$

Estuve haciendo algunas pruebas con una cámara planetaria Celestron NexImage5 y los resultados son muy buenos. La cámara me dá una escala de placa de 0.38"/px lo cual es una warangada dado que el poder de resolucion del telescopio es 1.45". Las imagenes son stacks con Registax de 300 cuadros en el caso del Sol y 120 cuadros para Venus. Recien son las primeras pruebas, pero con el tiempo iré mejorando y llevando la óptica al límite. Hasta ahora, una maravilla. #telescopio #refractor #kasai #oldscool #astronomy #astronomía #óptica #optics #japan

Complejo de manchas solares del 17/6/2025 a las 15:30 HLU con el Sol a 21º de altura.

$Venus a 25º de altura, se nota la aberración cromática producida por la refracción atmosférica, que es del orden de 0.5" o sea, casi 2 px.$ $Alfa Centauri, estrella binaria fácil de resolver, a unos 8.96" de separación medidos en la imagen. El FWHM de la imagen es 1.5" lo cual es muy cercano al límite teórico de resolución del telescopio de 1.45". O sea que posiblemente se puedan resolver estrellas binarias de separaciones del orden del poder de resolución, lo cual es impresionante. La imagen super puntual, no parece sacada con un refractor de 80mm.$ $Seeing atmosférico de 1.5". En la imagen se divisa el primer anillo de difracción, en el gráfico 3D se ve un poco pero no quedó muy visible en la captura.$

Difundimos actividad de interés mañana 18:30!! No se lo pierdan!

Desde el Observatorio Astronómico de Montevideo y el Museo de Historia Natural Dr. Carlos A. Torres de la Llosa los invitamos a la conferencia "La historia del Telescopio más antiguo del Uruguay" a cargo de Fernando Jorge Ivanauskas.

La misma será el próximo miércoles 11 de junio a las 18:30 horas en el Museo - Eduardo Acevedo 1427.
Simultáneamente será retransmitido vía videoconferencia (sin necesidad de inscripción previa) en el siguiente enlace:

Posteriormente a la conferencia se realizará una observación astronómica en el Observatorio Astronómico de Montevideo (edificio IAVA).

El día de la visita era también el día de CURE puertas abiertas y pudimos observar las manchas solares ya con el telescopio en su montura. Luego de noche en Ambá, el cielo estuvo espectacular. Pudimos observar el cúmulo globular Omega Centauri, cofre de joyas, la galaxia del sombrero M104, algunas dobles y algunas nebulosas como la de Eta Carinae, Orion, entre otras. El telescopio muestra anillos de difracción super marcados y una definición y un contraste que eran muy similares a los que eran visibles con el Celestron Mak de 12cm. #astronomía #astronomy #astrophotography #refractor #telescope #diy

Lunar #occultation of #Saturn on 21st August 2024 from #Oxfordshire, UK. 2x speed, captured with a #WilliamOptics 70mm #refractor 3x Barlow + #ASI120MC camera #SaturnOccultation #WaningGibbous #Moon

Had a pretty productive night! No weird dust issues, a minor process issue with me hitting the wrong button and only getting 1 image instead of 10 a few times, and I need to be more careful with focusing.
Got the Black Eye Galaxy, and M88 spiral, M90 spiral, and M17 the Swan.

M64 the Black Eye Galaxy. A tilted spiral galaxy with a dark half-circle smudge close to the center. There are concentric fainter outer bands.

Messier 90, a classic tilted spiral galaxy, like a more distant version of the Andromeda galaxy. Several arms surround a bright core.

Messier 88, another spiral galaxy. The arms have more dark lanes and are a little looser.

Messier 17, the Swan Nebula. Also known as the Checkmark or Omega nebula. The image has been oriented to make the nebula look like a swan on the water, heading right, with a bent neck. The area to the right has almost no visible nebulosity, the area behind the swan has large faint clouds.

One advantage of light polluted suburban skies is that a half moon hardly even registers. :blobcatspace:
Taking some Black Eye Galaxy data! Might try Markarians chain link. Taking out the AT125EDL Big Boy tonight, and the sensor I'm using tonight is tiny, so won't fit the whole chain.

$Night shot of large white refractor telescope in a mount next to a PC and chair. The night sky is heavily light polluted.$

@thomasfuchs
That's clever.

My feelings about #telescopes is this:

Give me a #refractor
Or give me death

(Well, maybe a #DOB)

All set up and imaging in the observatory tonight, but also took the time to finally get out my later father's telescope. Bought at some point in the early 80's it sat in his loft for years until cancer finally took him nearly 5 years ago. It's been awesome to finally get my eye to the same eyepiece he did years ago, and check out Jupiter and it's moons 🔭🙂 #observing #astronomy #refractor

$A selfie of me kneeling next my dad's refractor telescope.$

The outline of dad's telescope against the clear dusk sky with Jupiter twinkling in the background.

Car loaded with kit. Let’s see if I can get #c2022e3(ZTF) tonight by throwing a bit of #goto at it - or at least using my #telrad and a bit of dew heating. Might try my small@#refractor first… if no success then see if the #c8edge will do anything… #astrodon #astronomy #telescope #comet

#LunarOccultationOfMars 06:01 UT 8th December reprocessed. This image was taken as Mars re-emerged from behind the #Moon. #ASI120MC camera, #Celestrron 3x Barlow #WilliamOptics 70mm #refractor Full technical details are on my Flickr page #Mars #Occultation #LunarOccultation

Planet Mars emerging from behind the Moon

One final image from this morning's #lunarOccultationOfMars from North #Oxfordshire, UK Mars at 06:01 UT, after egress was complete. Best 60% of 2,000 frames, #ZWOASI120MC on a #WilliamOptics 70mm #refractor #Celestron 3x Barlow #Mars #MarsOccultation #FullMoon #LunarOccultation

I created this helpful graphic to show how different telescopes flip the image around (and upside down)...

Well, given that my local weather is not cooperating, I can share a pic of my scope then. This is a #refractor, and uses lens in the front to gather light, as opposed to mirrors. It’s kinda short as well for its size, so in practice that means that it’s more suited for wide field observing.

$Image of a refractor telescope.$

After a think while I was working today I decided to hedge my bets a little and go for a pair of telescopes. A 102mm refractor and a 127mm mak.

Given the breeze, moonlight, possible cloud later on I decided it wasn't a big Dob night.

#Refractor will be great for double stars and clusters and the #Mak will be good for #planets and the #moon

Telescopes assemble!

#Astrodon

Astronomy equipment waiting to be assembled

@Paul_Hill what #refractor have you got? I’ve got a small WO66mm which is great for wide field visual - but would love something larger with a longer FL…

At this stage it is carry on regardless. There seems to be plenty of observing time, but it will mean careful selection of a few good targets, fewer than intended. Over the day I will have a ponder about what I really want to have a look at & focus on.

So next stop will be later this afternoon when the #telescope comes out & I get everything aligned, collimated etc

#Refractor or #reflector? The conditions are suggesting to me I'll have more luck with glass but we'll see later on.
