), then you will get the value of "actual field of view". In this example, it is 7 degrees. Therefore, the effective field of view is improved, and the actual field of view is improved. However, the actual field of view will decrease when the magnification is increased.
exit pupil you will also find an exit pupil in many dual-tube telescope manuals). It is the width of the light that is emitted from the mesh. You can divide the aperture (unit: mm) by the magnification to calculate the pupil

To the photographic enthusiasts for detailed analysis to share the Canon SX60 HS adopted image processor and picture format.
Analytical sharing:
Canon SX60 HS employs DIGIC 6 image processors.
According to the information provided, you will be able to understand the Canon SX60 HS using what image processor. Canon for SX60 HS equipped with the fuselage of the ceiling flash, so that even without professional lighting equipment can be photographed with the normal exposure of photo
say, the focal length of the lens is 36-432; F = 100mm, and the focal length is twice that of f = 50mm. This computation is simple. Dividing the longest focal length by the shortest focal length can result in an optical multiplier of the lens. For example: 432mm/36mm = 12, then the lens is scaled by 12 times.The focal length is easy to understand. We all know that the longer the focal length, the larger the object to be taken. The shorter the focal length, the smaller the object to be taken. Th

relied on by the small aperture, but by fine-tuning the microscope. Note that the camera channel and the eyepiece observation channel should be consistent, that is, the most clear under the eyepiece is also photographed the clearest, so as to facilitate the photo. When taking pictures, the camera should choose the maximum aperture and wide angle. Do not use telescopic zoom, which makes the field of view sm

Tip: note that the ink needs to be added in the following way. After the pasted tape is removed, the contacts must be properly handled, the residual tape must be cleaned before installation and use. This method does not limit the number of times, the metering chip will return to the initial state, and is suitable for most HP ink cartridges (the Electronic contacts are the same ), you can use it with confidence.Decryption process of the black ink cartridgeFirst, prepare some transparent tape and

Identification of Sound Card chips:
Most of the current boards are integrated with onboard sound cards. When we install a motherboard driver, if we do not know the model of the sound card, we can open the chassis and carefully identify the words above the sound card chip, you can find the model of the sound card. The size of t
but does not stop, and the screen is stopped on the "set gap ".
Solution:
1> press the "reset" key to reset the system.
2> open the wind shield and enable the left and right pressure plates respectively. Perform the following checks in sequence:
3> check for fiber breakage.
4> check whether the optical fiber cutting length is too short.
5> check whether the fiber slot matches the optical fiber. And perform corresponding processing.
5. The optical fiber can be properly reset. When the gap is set

is around-voxels and change (and multifiltering would being more sensitive to that size); A 3-voxel-radius cluster is the voxels or so (if I ' m doing my math right). 6mm is a good place to start. If you ' re particularly interested in smaller activations, 2-4mm might is better. If you know your won ' t care about small activations and really would only look at large clusters, 8-10mm is a good range.
