A brief overview of Webcams and Astronomy. Not all webcams are made equal. For a webcam to be suitable for astrophotography it needs to be particularly sensitive to light. Webcams with CCD Charge Coupled Device chips are generally more sensitive than CMOS Complementary Metal Oxide Semiconductor chips, certainly in webcams, although some more recent makes of CMOS chips used in professional DSLR cameras are able to offer the required light capturing ability. The STAR ANALYSER is used here with an 80mm reflector and an unmodified Philips Toucam Pro webcam, to reveal the telltale signature of molecules in the atmosphere of. The Klf Flac there.

Here are some pics of my Phillips SPC900NC Webcam which I use to capture pictures and movie footage for astrophotography with my Orion Skyquest XT10 Intelliscope. Toucam Pro Software' title='Toucam Pro Software' />Generally if you are searching out a webcam for use with a telescope, try to find a CCD webcam, otherwise be sure that any CMOS webcam is sufficiently sensitive and has been tried by other astonomers. The Toucam Pro I and II models were the original favourite choice for astronomers. For example a very cheap webcam, the Philips SPC2. Jupiter May 15th, 2005 Jupiter December 1st, 2013 This represents my best work the Philips ToUcam Pro 740K and 8 Celestron SCT. This image is from my second. Introduction to MetaGuide. MetaGuide is a multifunction telescope tool based on realtime image processing of a video stream. Despite its power and functionality. NC is a 1. 3. Mpixel CMOS chip, but its Minimum Illumination is 5 Lux the amount of light it can detect and requires to operate effectively, whereas the SPC9. NCs CCD chip has a Minimum Illumination of lt 1 Lux, and hence why it is so popular for astrophotography. A typical family living room is lit to 5. Lux, the dark limit of civil twilight is 3. Lux, the full Moon overhead at tropical latitudes provides 1 Lux, the full Moon on a clear night provides 0. Lux, a quarter moon 0. Lux, and a moonless clear night sky with skyglow gives just 0. Total starlight shining through an overcast sky provides 1. Specifications for video cameras such as camcorders and surveillance cameras often include a minimum illuminance level in lux at which the camera will record a satisfactory image. A camera with good low light capability will have a lower lux rating. Still cameras do not use such a specification, since longer exposure times can generally be used to make pictures at very low illuminance levels, as opposed to the case in video cameras where a maximum exposure time is generally set by the frame rate. The SPC9. 00. NC uses the same Sony ICX0. QB CCD sensor as the Toucam Pros with a pixel size of 5. Pixels non interpolated. This table shows the chip is a 14 Type which has 6. Plastic DIP package with a CXD2. R Combined. timing pulse generator, and a primary colour mosaic Bayer filter mounted. The Sony ICX0. 98. QB CCD sensor is a 14 type with details as below. Type.

XT1. 0 on its dobsonian mount You will see what I mean if you try using the Toucam or Philips webcams with a dob mount it requires persistance and a lot of patience. As I understand, the SPC9. NC is now a discontinued model, but I was able to purchase mine from a supplier through EBay. Beware that more recent models of Philips webcams use a CMOS chip and may not be as sensitive as the CCD. A suitable alternative is the Philips SPC8. SPC9. 00. NC firmware uploaded into it using Wc. Rmac see resources section below. Generally cheap webcams do not offer high resolutions for movie capture, the norm for affordable webcams being 6. Anything greater than this generally starts to get more expensive. The webcam software andor driver software should also be able to control the Exposure and Gain, and additionally helpful is Brightness, Contrast, Colour or Black White options. There may also be other options for special features or capabilities specific to that model of webcam which may be useful to control the quality of astro photos. Most webcams are used for capturing movie at 5, 1. FPS frames per second, or for taking single shot photos of brightly lit objects with short exposure times of anything from a few thousandths, hundredths of a second to 14 or 12 a second. Generally the moon, planets and similar bright celestial objects can be captured and enhanced using software such as Registax or K3. CCDTools, which will align the many frames of movie footage exactly over each other, then stack them together, then sum all the frames into a single enhanced composite image which is far brighter, less noisy, sharper and clearer than any single frame would have been. But to take single shots of dim night time objects like stars, galaxies and nebulae requires the webcam to be capable of taking very long exposures, more like 5, 1. One of the prime reasons for me searching out this particular webcam was because after considerable research on the Steve Chambers SC Long Exposure mod, not only was the SPC9. NC webcam still fairly readily available, and used a good sensitive CCD sensor chip, it also became apparent that the Long Exposure modification could be made much more easily than for some other webcam models, which require some very fiddly soldering see Useful Resources section below for link to M. M. J. Meijers web site, for more info on how to actually make the Long Exposure mod. While I realise that my Orion XT1. Dobsonian base wont be any use for long exposures, I wanted a webcam that could be modified, if and when I get another telescope mount that is more suited to deep sky astrophotography Update I now own a Celestron C6 SGT XLT SCT on EQ5 mount. There are two main problems regarding long exposures The telescope must be able to track very accurately the apparent motion of the night sky as the Earth rotates, otherwise the image will become blurred and elongated. While the CCD chip is turned on to gather as much light as it can during the exposure, the electric current passing through the chip heats it, and this can result in glow effects or hot pixels. While point 2 can be dealt with using software to create a dark frame map, which is then subtracted by post processing the image, point 1 is absolutely crucial and means that Dobsonian mounted telescopes such as the Orion Skyquest range are simply incapable of taking long exposure photos, unless the Optical Tube is mounted on an Equatorial tripod, or the Dobsonian is modified to sit on an equatorially tracking platform, or the Altitude and Azimuth axis are motorised. To combat the heat problems described in point 2 above, it is possible to attach heatsinks to the imaging chip, and use fans to aid cooling. Additionally a special type of semiconductor called a Peltier chip is used in conjunction with a heatsink to act as a kind of refrigerator to cool the imaging chip down even more, often to temperatures well below freezing. For example Peltier chips are used in portable coolboxes to keep food and beer cold. All these different things cooling, heatsinks, fans, peltier chips, high resolutions, and better quality imaging chips soon add to the expense of professionally manufactured astronomy cameras, and this is why some of them can cost hundreds or thousands of dollarsNote that there is probably no point in making the Long Exposure mod to your webcam unless your scope has Equatorial tracking. Anyway, for the paupers, newbies and experimentalists among us we can try our hand with a cheap webcam. The Field of View Drift Method. It is possible to get reasonable pictures of the planets even with a Dobsonian mounted scope, using the Field of View Drift method, as I like to call it. You line up the planet in one corner of the webcam screen view, then let go, leaving the scope static, and let the planet drift diagonally across the field of view as the Earth rotates, roughly to the opposite corner. With my Orion XT1. Barlow lens to increase magnification the drift takes betwen 3. This means a webcam movie capture of 1. FPS will result in about 3.
