- What is better for imaging, CCD or DSLR?
Most of us here seem to use astro CCD's rather than DSLR cameras. You might want to post this question to the Cloudy Nights DSLR forum. Nearly all the DSLR images can rival CCDs for deep sky imaging of the brighter objects (without cooling they just can't handle the really faint stuff but are improving rapidly) use various canon cameras. But for emission nebula with any brand you will need to remove the IR filter or replace it as the ones that come with DSLR camera block most hydrogen alpha light, the main emission of such nebula. This causes them to come out green rather than pink. But since the human eye also sees very little hydrogen alpha light this color is what the eye would see. Just not what the camera sees. Also without much response at the primary emission frequency (within our eye's passband at least) exposure times will be much longer. For planetary work the best imagers use a high quality USB 2 web cam. These can take a thousand images a minute allowing the best to be stacked with a program such as Registar. You can't begin to do this with anything but a web cam. With a DSLR or CCD you are the mercy of seeing and have to hope you trip the shutter at just the right instant when seeing is perfect. With the web cam and good software this luck element is eliminated.
- What is ccd camera and how its work?
A CCD camera works exactly like a regular camera, but instead of focused light falling on film, the light strikes the CCD.
A CCD works sort of like an array of thousands or millions of tiny solar cells, each one a pixel, collecting a tiny bit of light and converting it into electrons. The electrons are collected by an analog to digital converter that changes the pixel's value into a digital value. From there the data is manipulated by a processor or stored to memory.
- What is the difference between a CCD and a lens camera? Could you explain the following:focal length, exposure time, aperture setting, Resolution, Film speed, Shutter time?
Focal length - on a digital camera this will be x1.5 that of the non digital camera. For a example a 200mm lens on a 35mm camera is a 300mm lens in digital world. This is to do with the amount of data captured onto the sensor.
Exposure time - This is the same for both 35mm and digital. It's the measurements of blacks and whites in a shot.
Aperture settings - this is also the same on both 35mm and digital. It's how much the 'eye' opens on the camera when you take a shot.
Resolution - this is the big measurement for digital. its the amount of pixals that the cameras sensor is able to capture in an image. In theory the biger the better, but this is not always true, it's also how a camera deals with the pixils. over 6mp and you're good.
Film speed - on a digital camera this still known as ISO but it's the digital equivalent which basically makes the sensor more or less sensitive to light. On a 35mm it's the sensitivity of the film you are using.
Shutter time - this is the same on both. its how long you leave the shutter open during a single shot.
