The Wishing Well Cluster ( NGC 3532 ) in the constellation Carina by Mike O'Day ( 500px.com/MikeODay )

This large bright open cluster, when seen through a small telescope, looks like a collection of brightly gleaming silver coins shimmering at the bottom of a wishing well and hence the name.

First recorded in 1752 by Nicolas Lacaille, NGC 3532 contains around 120 stars superimposed on the expanse of the Milkyway and is visible with the naked eye from lower latitudes.

The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 ± 20 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2000 times the mass of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula.

The Orion Nebula is one of the most scrutinized and photographed objects in the night sky, and is among the most intensely studied celestial features. The nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. Astronomers have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the nebula.

It was nearly a full moon, but a rare clear November night, so I tried running Ha as a luminance channel. Seems to work pretty well both in terms of dodging the moonlight and in terms of clarity.

The Southern Beehive Cluster ( NGC 2516 ) in the constellation Carina - by Mike O'Day ( 500px.com/MikeODay ).

Because of its similarity the “The Beehive Cluster” ( catalogued as M44 by Messier ), NGC 2516, which is only visible from lower latitudes, has become known as the “Southern Beehive Cluster”.

At a distance of around 1300 light years, NGC 2516 is relatively close to us and resides in the same spiral arm of the Milkyway as we do.

Containing around 100 stars, with a number of them in the magnitude 5 to 6 range, NGC 2516 has an apparent magnitude of 3.8 and is visible to the naked eye as a small bright hazy patch at the edge of the Milkyway.

This is my first image done using my first telescope. It could have been much better if the guiding camera was working... I'm now waiting for a replacement one. I had to throw away 40+ shots because of the tracking problems, very frustrating.

Spent 6+ hours on the editing, following a 1:15 hour in-depth tutorial in Spanish.. I don't speak Spanish.

I used the Ha capture both as red for RGB and luminance which allowed me to extend the imaging despite the Moon and shorter night. It seems to have worked out well in part due to the amount of Ha in the region.

M109 (NGC 3992) est une galaxie spirale barrée située dans la constellation de la Grande Ourse à environ 48 millions d'années-lumière.

On distingue également trois de ses galaxies satellites, plus petites : UGC 6923, UGC 6940 et UGC 6969.

Le rayon lumineux à droite de la galaxie est issu de l'étoile Gamma de la grande ourse, très brillante et très proche.

"Quasar, an astronomical object of very high luminosity found in the centers of some galaxies and powered by gas spiraling at high velocity into an extremely large black hole."

Someone once asked me "What's the most distant thing you have ever seen". Kind of an interesting question really.

This takes the prize. Quasar 3c 309.1 off the bottom of the Little Dipper. Not much to look at, just a little dot really, but at a distance of 8 billion light years. Hard to imagine that photon left there 3 1/2 billion years before our planet even formed. Hard to imagine too a light source that powerful.
