Top 6 Brightest Deep Space Objects
Deep space objects are not just for those with access to large telescopes or for Hubble to bring to us, some of the most common catalogued objects are visible with binoculars.
When it comes to binoculars and back garden telescopes, the most important factor isn't magnification, as the greater the magnification, the dimmer the object becomes, even if it looks larger.
Rather, you want to find the largest aperture, the size of the light gathering lens or mirror. That said, any pair of binoculars lying around is going to be better than what you can see with your naked eyes, particularly if you're living in a major conurbation where light pollution obscures so much of the night sky.
M45 - Pleiades - Taurus, Mag 1.2, naked eye
As featured recently on this blog, the open cluster Pleiades are visible with the naked eye as a smudge of stars, often referred to as the Seven Sisters and used as a eye sight challenge in the past. To get a sight of the nebula that glows blue (as the stars are blue giants), a good steady view with binoculars should reveal this.
A hint, sometimes with deep space objects, the best way to view them is not to look directly at the object, but rather, look with the side of your eye, and the colours seem to stand out much more than directly observing can.
M31 - Andromeda Galaxy - Andromeda, Mag 3.4, naked eye (but best with binoculars)
Theoretically bright enough to see with the naked eye, and in dark areas this may appear as a slight cloud over an area around the size of the moon, but in cities, Binoculars are needed to see this, with the structure just about visible for those with keen sight.
IC 1396 - Elephant Trunk Nebula - Cepheus - Mag 3.5, binoculars
While in the darkest of environments you can view this with the naked eye, everywhere else a pair of binoculars is recommended.
NGC 7000 - North American Nebula - Cygnus - Mag 4, Binoculars
This nebula covers an area 4 times the size of the moon, but that also means, it's brightness is stretched over it, making naked eye observation near impossible. Binoculars are needed to view this, just near the brightest star Deneb in the constellation of Cygnus.
NGC 1499 - California Nebula - Perseus - Mag 5 - Binoculars/Small Telescope
Even with binoculars this can be quite a challenge to see, and best viewed from very dark environments or smaller telescopes. As with the North American nebula, the size covered in the sky is responsible for making it harder to see.
M8 - Lagoon Nebula - Sagittarius - Mag 5 - Binoculars
Another recent feature in my blog, the Lagoon Nebula is just about visible with the naked eye under the right conditions, but in cities, best viewed by binoculars. The nebula being in Sagittarius is falls over the central bulge of the Milky Way, although it is 4,000 light years from us, the background of stars are 20,000 light years off.
