Vega (Alfa Lyrae / α Lyr) es una estrella de primera magnitud (en la clasificación de Ptolomeo) de la constelación de la Lira y la principal de la misma. Su nombre proviene de la latinización medieval de su denominación árabe, waqi (ؤاقع) que significa que cae[cita requerida].

Para un observador ubicado en una latitud norte central, se aproxima al cenit durante el verano boreal. A tan sólo 25 años luz, se cuenta como una de las estrellas más cercanas al Sistema Solar, y como una de las más brillantes entre las vecinas del Sol junto con Sirio y Arturo. Es la quinta estrella más brillante del cielo nocturno.

Según análisis espectrográficos, Vega está en la etapa de secuencia principal, es decir, está convirtiendo hidrógeno en helio en su núcleo. Puesto que las estrellas más masivas y brillantes consumen su combustible más rápidamente, la vida de Vega se estima solamente en mil millones de años, un décimo de la de nuestro Sol. Vega es dos veces y media más masiva que el Sol y arde con una luminosidad treinta y siete veces la de éste.

Vega posee un disco de polvo y gas a su alrededor que fue descubierto por el satélite IRAS a mediados de la década de los 80. Esto puede significar que o bien tiene planetas, o que se podrían formar relativamente pronto.

En el año 13.600 será la estrella Polar (lugar ocupado en estos momentos por Polaris) debido al fenómeno de la precesión de los equinoccios.

Los astrónomos profesionales han utilizado a Vega para fijar los baremos absolutos de brillo fotométrico, lo que supone que la magnitud visual de Vega es aproximadamente cero en todas las longitudes de onda. La intención original era que el valor fuera exactamente cero, pero en la práctica no resultó así. Por ejemplo, en el filtro V de Johnson (el más usado por los astrónomos en el rango visible o visual), la magnitud de Vega es 0,026 ± 0,008, y en otros filtros hay también desviaciones de unas pocas centésimas.[1] [2]

Tiene también un espectro relativamente plano en la región visual (un campo de longitud de onda que va desde los 350 a los 850 nanómetros, la mayoría de las cuales son visibles al ojo humano), de modo que las densidades de flujo son aproximadamente iguales, 2000-4000 Jy. La densidad de flujo de Vega se reduce rápidamente en el infrarrojo y se acerca a los 100 Jy en 5 micrómetros).

Vega es un ejemplo de estrella que rota a gran velocidad, como Altair (α Aquilae) o Regulus (α Leonis), por lo que su radio ecuatorial es significativamente mayor que su radio polar. Una velocidad de rotación alta también genera diferencias de temperatura superficial entre el ecuador y los polos. La velocidad de rotación en el ecuador de Vega es de 275 km/s, lo que hace que los polos estén a una temperatura superficial de 10.150 K y el ecuador a una temperatura de 7.900 K.[3]

The Pelican Nebula (also known as IC 5070 and IC 5067[1]) is an H II region associated with the North America Nebula in the constellation Cygnus. The gaseous contortions of this emission nebula bear a resemblance to a pelican, giving rise to its name.[1] The Pelican Nebula is located nearby first magnitude star Deneb, and is divided from its more prominent neighbour, the North America Nebula, by a molecular cloud filled with dark dust.

image captured with 1250mm G5 celestron astronomical telescope prime focal w/o tracking

Note : Actual naked eye observation appeared yellowish in colour. The short time exposure of 1/1000 resulted in a b/w image. To achieve near actual colour, you're need to have an exposure of 1/2s or more which invariably needs tracking in order to obtain a sharp image.

Despite being our nearest celestial neighbour, it's about 238,000 miles away. That's quite a considerable distance to cover if you're planning to spend your next holiday there. Make sure not only you got to bring enough food but air as well cause' you'll need a lot of luck to find someone that sells air on the moon.

Place the entire family there indefinitely and they can exercise their usual worst form of inconsiderate behaviour at the most extreme level, make all the irritating noises they want without disturbing any human being ever.

This was my pride and joy a few years ago. It is an 8" Celestron Ultima PEC SCT. I sold it to get out of debt. It is one of those decisions where I kinda regret selling, but it was something that needed to be done.

This was my third telescope. The first was a 60mm refractor my parents got me for Christmas as a kid. The second was one I purchased myself. It was a Meade 8" sct.

I was driving back from a star party, about 3am and the danged tailgate on my truck dropped down and the telescope fell out on to I-26. You might be amazed how many pieces one of these will turn into when a semi runs over them.

This one is not computerized like so many of the current scopes. It has setting circles, manual, and I could generally find objects quicker than the guys with the goto scopes.

I've tried finding another one of these, but they were older when I had mine and they don't make them like this now. C'est la vie, n'est pa?
