The first is to capture the LiveВ View video feed with a computer using a USB connection.В The other is to record a cropped video with the cameraВ itself, if your camera model has this feature. There are two planetary imaging ways to record planetary videos with aВ DSLR at a 1:1 pixel ratio. The author captured each of these images using a Celestron C11 EdgeHD operating at f/29 and a Canon EOS Rebel T2i in Live View mode. But you can also use your DSLR as a high-speed video camera to take great high-resolution images of the Sun, Moon, and planets like the fine examples above of Neptune, Uranus, Mars, Saturn, and Jupiter. ItвЂ™s not uncommon to see deep photographs of nebulae and galaxies taken with a stock DSLR, or the Milky Way captured over a picturesque landscape. ItвЂ™s surprising what DSLR cameras are capable of these days. Use a starВ near your target to collimate your scope just before you shoot to ensureВ your best collimation. Newtonian reflectors, Schmidt-Cassegrains, and other mirror-based telescopesВ need to be precisely collimated to perform at their best. This down-samples every frame, reducing the resolutionВ of the image.

In 1080p high-definition video mode, the camera records an image that is only 1,920 pixels wide by 1,080 pixels high.

Although you can use normal high-definition 1080p or 720p video modes for lunar and solar imaging with great results, you generally donвЂ™t want to use this mode for planetary work because it resamples the image recorded by the cameraвЂ™s detector, and you will lose fine detail.ДЇor example, the sensor in the Canon EOS Rebel T3i (also called the 600D) has an array of 5,184 by 3,456 pixels. Cameras with Live View offer the easiest route, using the zoom preview mode to get to a 1:1 crop of the central portion of the cameraвЂ™s detector. The trick to capturing the highest-resolution, planetary imaging details with a DSLR is to use a mode that allows you to record the image off the cameraвЂ™s sensor at its nativeВ pixel resolution. This is whereВ two video modes on your DSLR camera, Live View andВ high-definition video, come into play. To capture the best planetary images these days, theВ preferred technique is known as вЂњlucky imaging.вЂќ ThisВ method records thousands of frames in a high-speedВ video stream, which you can later sort for the best framesВ to stack into a final high-resolution image. But few users realizeВ that the video modes available on DSLR cameras are greatВ for recording high-resolution planetary images. And, of course, DSLRs can be usedВ to snap daytime photos of any kind. Using the latest models,В you can shootВ long-exposure deep-sky images, create time-lapse moviesВ from a set of still images, or record high-definition videoВ with a quality that exceeds footage recorded by some dedicatedВ video cameras. An EF-S55-250mm f/4-5.6 IS lens will also be offered separately for $299.Digital single-lens reflex cameras (DSLRs) today are amazinglyВ versatile. That lens will also be sold separately for $199.

For $899, Canon will bundle the EF -S18-55mm f/3.5-5.6 IS zoom lens. The XSi will be available in silver or black finishes.

The XSi will be the first Rebel to use SD/SDHC memory cards rather than CF cards. According to Canon, it uses face-detection technology to prevent underexposure when a face is backlit.ДЄdditional features include a nine-point cross-type AF system, a 3.5 fps burst mode to 45 high resolution JPEGs or up to six RAW files. An auto lighting optimizer will automatically correct image brightness and contrast.

Several features have migrated down from CanonвЂ™s high-end 1D Mark III SLR including a highlight-tone priority mode and a high ISO noise-reduction function.

The sensor can vibrate to dislodge dust and supplied software can remove any subsequent dust from images after capture. The XSi is CanonвЂ™s first consumer-level SLR with live view and it can focus on an image without the reflex mirror coming down. The 12.2-megapixel XSi camera will offer an improved autofocus sensor, 14-bit A/D conversion, a 3-inch live-view LCD and CanonвЂ™s new DIGIC III processor. Canon said it would ship the new EOS Rebel XSi, the successor to its consumer-level Rebel XTi digital SLR, to dealers this April.
