With this astronomy video, you can learn about the processing of color videos. This also demonstrates how dust spots that appear on the video are automatically removed by the processing (no need to do a flat-field).

ATTENTION: The video is in black and white (to obtain better images). The output image you get will then be combined with
a color image
(eg this one: here) in a specialized software, eg Photoshop using the technique of layers explained here.

As you can see it, the background of the sky on the raw images is bright because shots were made at twilight. To solve this problem, use this bmp image which represents the background of the sky/dark/offset. Don't forget to adjust the threshold during processing.

 Except for a few videos, all of the videos about the planets seen on this page have been made with a telescope Meade LX200 10 "(not a new LX200 ACF). The Headquarters of Meade is based in the USA and the firm shows a wide range of telescopes starting with the ETX, then the LX90 and finally the high-end LX200, with a good price for money ratio. The new version of the LX200 classic is the LX200 ACF, which differs from its brother by the optical formula. Indeed, the Meade LX200 ACF telescope is a pseudo coma-free Ritchey-Chretien while the old model is a Schmidt-Cassegrain. Thus, the new one is more suited to the photography of stars because it has a field of view without coma. Astronomical telescopes at entry level seen on Meade's website are not particularly appreciated by the community of amateur astronomers: you can find plastic and the goto system - although effective - is not very useful because it operates on small aperture telescopes that can't solve details on the galaxies and other objects of the deep sky. You'll no doubt have the opportunity to see many photos taken with Meade telescopes on the forums of astronomy. Without wishing to advertise for the brand Meade, I think that these telescopes (from Meade LX90 to LX200 ACF) have a large potential on ccd imaging and video. If you are photographing with this type of telescope, be aware that you'll be forced to limit the length of your exposures in order to avoid the field rotation effect which is inherent with alt-azimuth mounts. Fortunately, it is easily removed by a computer (see technical section of my site). For deep sky imaging, it is necessary to have a wedge placed below the fork mount. Celestron is the direct competitor of Meade, but I'm not familiar with this brand, so I won't say anything about it. I describe in more detail my views on Meade's astronomy equipment on this page. |
