The Next Great Observatory: Webb Space Telescope

Please join us on Facebook for the latest science news and videos: tinyurl.com James Webb Space Telescope (JWST), Part 1/2 – The Next Great Observatory. — Please subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com • www.youtube.com — The James Webb Space Telescope (JWST) is a large, infrared-optimized space telescope, scheduled for launch in 2014. JWST will find the first galaxies that formed in the early Universe, connecting the Big Bang to our own Milky Way Galaxy. JWST will peer through dusty clouds to see stars forming planetary systems, connecting the Milky Way to our own Solar System. JWST’s instruments will be designed to work primarily in the infrared range of the electromagnetic spectrum, with some capability in the visible range. JWST will have a large mirror, 6.5 meters (21.3 feet) in diameter and a sunshield the size of a tennis court. Both the mirror and sunshade won’t fit onto the rocket fully open, so both will fold up and open once JWST is in outer space. JWST will reside in an orbit about 1.5 million km (1 million miles) from the Earth. • www.jwst.nasa.gov .

Sky-Watcher Great Start 70 AR-AZ2 70mm Refractor Telescope

412IAR9hVWL. SL160  Sky Watcher Great Start 70 AR AZ2 70mm Refractor Telescope

  • 70mm diameter optically coated 2-element lens
  • Rigid double-strut tripod
  • Red dot finder
  • 1.25-inch Super Plossl eyepieces (12mm, 25mm)

The Skywatcher GreatStart 70AR-AZ2 is a great value in a small telescope, with some real improvements over the typical 60mm beginner scope. Instead of wildly exaggerated claims of “500 power” magnification, Skywatcher equips the SW 70AR-AZ2 with the basics: excellent optics, two Super Plossl eyepieces, a 2X barlow lens, and a solid Alt-Azimuth mount. The package also includes illustrated instructions and planetarium software for your PC. Skywatcher’s GreatStart 70AR-AZ2 features unusually good optics for an entry level telescope. The best objects for small telescopes are bright objects like the Moon and planets. When I look at the Moon for example, I‘m treated to sharp, high contrast views of the Moon‘s mountains, craters and lava flows. The little orange disk of Mars, the rings of Saturn, and even the cloud bands of Jupiter all show up quite nicely with the 12mm eyepiece, about 58x magnification. Planet details show up even better when I add the 2X Barlow for a total magn

Camera 450D – Excellent Beginner Camera, Not So Great Lens

THE BODY

this is the first slr camera I have owned myself despite having used others. without going into too much detail the body is very good quality with well laid out and easy to understand buttons. I would have like the grip to be a little more chunky particularly when using the exposure lock and AF selection as it can be slightly awkward although I do have large hands and I am probably being a bit picky.

the body of the camera is light and has more than enough features for someone who is just getting into slr photography.

it has several point and shoot modes such as portrait, macro, sport etc as well as a full auto I guess is ok if you happen across something you need to shoot quickly. however you should really try to avoid these auto modes.

luckily the camera has many program modes including shutter and aperture priority modes which once you master will dramatically improve your photos (particularly the aperture mode)

THE LENS

Unfortunately the lens that comes in this kit is not all that great. it is light and it does seem well built (I dropped mine just the other day and its fine) however its a lot slower to focus than the USM lenses canon offers and that can cause problems at times.

photos can appear a little soft unless shot at the narrower aperture (f16 and above really).

the thing that lets the lens down most in my opinion is the ability to knock the background out of focus. you really have to work hard to get a good amount of blur in the background, your gonna struggle to get good results at anything less than the full 55mm focal length at the widest aperture making it a little poor for macro shots, whilst being just ok for portraits. this lens would be satisfactory if you don’t wanna take photography too seriously but it does limit your results.

CONCLUSION

In my opinion the body is well worth the money and comes in cheaper than some of the equivalent nikon cameras.

as for the lens I would suggest buying the body and choosing a separate lens. I have only owned this camera 3 months and I am already wanting to replace the kit lens. look for a canon USM lens or one of sigma image stabilizer lenses

Best Bird Lens for Canon – Cheap – Get Great Bird Photos for Less

Do you know how much the best bird lens for a Canon DSLR costs? You could buy a new car… or a bird lens for your Canon.

I’ll just come right out and tell you that the very best one you can buy is the 600mm. And, yes, it costs more than ,000.

But we want something much cheaper here. In fact, dirt cheap would be nice, but that will not happen, because good lens glass just is not cheap. So forget that K beast until you win the lottery.

There are a few less expensive lenses that will do a really good job, but they also cost upwards of ,000. So… what’s a photographer on a budget supposed to do?

There are a couple of solutions to the problem that won’t cost you thousands of dollars and your first born child.

First, there are a few lenses that will do the job for much less than those listed above. Of course, if you are going to pay less, you will have to realize that the results will not match up, especially if you are going to go trekking through the wild, toting you camera and gear. (One of the suggestions is to NOT go trekking, but have the wildlife – the birds – trek to you.)

You can opt for a shorter range piece of glass. There are some great lenses in the “under 400mm category” that will give you some really good shots. Here are a few that you might consider:

Canon 300mm f/4.0 L IS USM – this one costs a little over 00. Sure, that might be more than you paid for your DSLR, but if you want results in this area, you will have to make some concessions monetarily.

Canon 100-400mm f/4.0-5.6L IS USM – another gem that runs about 00. Photographers who own this baby absolutely LOVE IT. Most would not trade it for anything.

Sigma 150-500mm f/5.6-6.3 – notice the 500mm number. That is way good. The lens has gotten some really good reviews from folks who use it. The one thing about this puppy is that you will need some pretty decent light because it does not have a very large aperture to start with. So, lots of light and a tripod will be assets when using this one. Cost is under 00 – yippee!

I save the best for last. You can take great photos with bird lenses that are not even considered by most people in this category. How? you might ask.
The secret is that you get the little feathered creatures to come to you. Set up a smorgashbord of delights for them to feast upon. And do it in a way that you can get the best images ever.

My personal setup is right outside my kitchen window. I have a deck that I attached some cut up branches to. I drilled holes into the branches to make feeding stations. Then I situated my feeders in such a way as to allow me the very best angle possible. It took a little tweeking, but the final setup works really well.

And here’s the best part. I use my Canon 70-200mm f/4.0 USM lens. This little thing only cost me about 0. I can also use my newest Sigma 18-250mm lens to take the shots when birds come too close for the other one.

A little work on your part can save you lots of cash. Plus it will keep you in the comfort of your own home where you can enjoy some great photography and a cup of coffee.
For more about these great bird lenses for Canon DSLRs, visit www.digital-photographic-resources.com.

I love photography and all things related to it. Cameras, camera gear, and image editing software fascinate me, so I am either buying the newest piece of equipment (or software) or researching my next purchase.
