... We can help students grasp the significance of Hubble's extremely keen eye, and learn a bit about angles and math in the process, with the following in-class activity. ... Looking through binoculars or telescopes allows us to magnify a small section of the sky. To measure sizes or distances in that small section, astronomers divide a degree into 60 smaller pieces called arcminutes, and further subdivide minutes into 60 smaller sections called arcseconds. ... 30 feet = . ... 36 seconds . ...

Astrophotography Forum Message . ... The resolution of a CCD camera does not depend on the number of pixels in the camera, rather it depends on the size of the pixels making up the chip and the focal length of the lens forming the image. ... A larger chip made from the same substrate will have identical pixel sizes, just more of them. ... With a fixed focal length telescope we don't have that luxury, in which case smaller pixel size rather than larger chip size is the only way to increase resolution. ...

. These low-resolution radar images of asteroid 2007 TU24 were taken over a few hours by the Goldstone Solar System Radar Telescope in California's Mojave Desert. Image resolution is approximately 20-meters per pixel. Next week, the plan is to have a combination of several telescopes provide higher resolution images. NASA/JPL-Caltech

... CorMASS (Cornell Massachusetts Slit Spectrograph) is a low-resolution (R~300) prism cross-dispersed NIR Spectrograph. It has been used on the Palomar Observatory 60-inch telescope, the Vatican Observatory 1.8-meter telescope, and the Magellan 6.5-meter telescope but resides at APO until further notice. ...

... In combining the data, it is assumed that the low resolution image better represents the short spacing data, whereas the high resolution best represents the fine structure. ... Key: out The output image. ... Key: factor The flux calibration factor. ... In practise, the calibration may not be perfect, and an extra calibration factor will be required to align the flux scales. "factor" gives the factor to scale the low resolution image to put it on the same flux scale as the high resolution image. ...
