Please join us on Facebook for the latest science news and videos: tinyurl.com ESOcast 10: GigaGalaxy Zoom Project – The Sky, From The Eye To The Telescope. — Please subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com • www.youtube.com — In the framework of the International Year of Astronomy 2009, ESO has launched a new project aimed at connecting the sky as seen by the unaided eye with that seen by hobby and professional astronomers. The project, called GigaGalaxy Zoom, reveals three amazing, ultra-high-resolution images of the night sky that online stargazers can zoom in on and explore in an incredible level of detail. The reward is the most breathtaking dive ever made into our Galaxy, linking the sky seen by all with the cosmos studied by astronomers. In this episode of ESOcast we will explore the unique and amazing GigaGalaxy Zoom project, which reveals the whole night sky as it appears with the unaided eye from one of the darkest deserts on Earth. The project allows users to zoom in on a rich region of the Milky Way with the magnification offered by a hobby telescope and then to go one step further, using the power of a professional telescope to explore details of an iconic nebula. Most of the photographs comprising the three GigaGalaxy Zoom images were taken from La Silla and Paranal, two of ESOs observing sites in Chile. The wonderful quality of the images is a testament to the splendour of the night sky at these ESO sites … Video Rating: 4 / 5
The key in buying a telescope is aperture size and making sure that the opening of the telescope is as large as possible.

Question by Bobbyo: Will my Sigma lens from my old Canon rebel work on a new xsi?
I have a Sigma telephoto lens (70-300mm 1:4-5.6) and I have one of the original rebels. Will this lens work with a new canon xsi if i were to buy the new camera? I want to be sure before i purchase the camera that this telephoto lens will work. Again, I have one of the original Canon Rebel’s and want to upgrade to a Canon xsi. WILL THE LENS WORK WITH THE NEW XSI???
10 POINTS!!!!!!!!!!!!!!!!!
Best answer:
Answer by skidd yeah it will work. All the Canon’s digital or not have the same mount. the Digital rebels also have the internal drive motor so it will auto focus aswell. : )

Sigma DP2 is one of the most powerful compact digital camera released by Sigma Corporation. The camera features 14 mega pixel camera, 24.2 mm F2.8 lens, photo pro software, and three metering and four exposure modes. The camera supports three types of memory cards, including SD (Secure Digital), SDHC (Secure Digital High Capacity), and MMC (MultiMediaCard). These three storage devices save photographs, audios, and videos in the form of digital data. This digital data saved in any of the above memory cards becomes inaccessible, if the card gets corrupted. To access the digital data post memory card corruption, the user needs to restore a copy of all the files from an updated backup. However, if a backup copy of data is not available or is corrupted, then you need to use advanced Photo Recovery Software.
Consider a practical case, where your SDHC memory card gets corrupted due to improper shutdown of the camera. When you attempt to access the files saved in the SDHC card, you are unable to do so. The below error message stops you from accessing the data:
“Incompatible file system. Format Card”
Corruption in card primarily occurs when you turn off the camera while the ‘busy lamp’ is on. In such cases, the camera is still accessing (performing read/write operations) the card.
To prevent the memory card corruption due to any such instance, you should:
Never remove the card when the ‘busy lamp’ is on.
Never remove the battery while the ‘busy lamp’ is on.
Never apply vibrations when the ‘busy lamp’ is on.
However, if the card has become corrupted due to any of the above reasons, and you are not able to access the files in the card, then you need to format the card in the camera. However, to recover the formatted data, you need to use an advanced Digital Photo Recovery Software. Such Photo Recovery tools recover formatted data from all kinds of memory cards, including SDHC memory card.
Stellar Phoenix Photo Recovery is a powerful application to recoup lost, deleted, and formatted data from any digital storage media. Compatible with both Mac OS X and Windows OS, the Photo Recovery utility can be used by any photographer, whether a novice or a professional. To analyze the functionalities of the software and to preview the lost files, you can download its demo version.

I bought it because it was CHEAP and it works on NIkon DX format DSLR. I am using this lens on the recently purchased Nikon D2H (Professional Camera from 2003-04). Even though it is only a 4MP camera, enlargements can be made up 20X30 without loss of full resolution. The lens is nice and compact. The overall length does not change when zooming in and out. Any questions or comments are welcome.
