The telescope is equipped for the occasion with the focal reducer Takahashi X0. The quality of the sky corresponds to urban conditions Castanet - Tolosan observatory, in the close vicinity of the city of Toulouse - south of France. The equipment used for this observation. First an image of the star CW Leo - probably one of the first made by an amateur. This star is a very discrete object in visible part of the spectrum , but becomes the brightness object of the sky when it is observed with wavelength upper to 5 microns. It is located in the Leo constellation at coordinates
Infrared astronomy - Wikipedia
The electromagnetic spectrum includes gamma rays, X-rays, ultraviolet, visible, infrared, microwaves, and radio waves. Infrared is broken into three categories:near,mid and far-infrared. Near-infrared refers to the part of the infrared spectrum that is closest to visible light and far-infrared refers to the part that is closer to the microwave region. Mid-infrared is the region between these two. Near-infrared, behaves in a very similar way to visible light, and can be detected using similar solid state devices. For this reason, the near infrared region of the spectrum is commonly incorporated as part of the "optical" spectrum, along with the near ultraviolet.
Backyard telescopes and amateur eyes see where “pro” astronomers can’t
Infrared astronomy is the branch of astronomy and astrophysics that studies astronomical objects visible in infrared IR radiation. The wavelength of infrared light ranges from 0. Infrared falls in between visible radiation, which ranges from to nanometers , and submillimeter waves. Infrared astronomy began in the s, a few decades after the discovery of infrared light by William Herschel in Early progress was limited, and it was not until the early 20th century that conclusive detections of astronomical objects other than the Sun and Moon were made in infrared light.
Welcome to CfA's resource page where a wide variety of information is available to all who love astronomy and astrophysics. The main body of data in the ADS consists of bibliographic records, which are searchable through our Abstract Service query forms, and full-text scans of much of the astronomical literature which can be browsed though our Browse interface. Integrated in its databases, the ADS provides access and pointers to a wealth of external resources, including electronic articles, data catalogs and archives. We currently have links to over 5. Designed to provide students and teachers nationwide the tools to investigate the deep sky from the classroom, this NSF-sponsored project, with in-kind contributions from Eastman Kodak Company and Apple Computer, endeavors to create a "virtual community.
