Photographed with a digital camera coupled to a telescope or spotting scope, was born in Malaysia in 1999 when Laurence Poh took the first shots. Since then it has spread to the east and then to Canada, Australia, Belgium, USA, France, England, Spain, Germany and, of course, Italy.
Born as the first tool to document subjects hardly approachable in their environment, with a very low image quality, is subsequently developed in a short time, to involve manufacturers of telescopes as Kowa, Leica, Optolith Swarovski, Zeiss ecc. ecc., and manufacturers of compact digital cameras such as Fuji, Nikon, Olympus, Sony ecc. ecc., and today great results and, for some subjects, only.
In addition to equipment costs, significantly lower, the diffusion was also the advantage, unique to have so powerful that the focal world of traditional photography did not exist. We think that a scope with a 20X eyepiece can get to a focal length equivalent to that of a conventional lens 35mm 1500-3000mm. The quality, when used apochromatic telescopes with a diameter of at least 80 mm. and digital cameras with optical quality least 5ml. pixels and a magnification factor of around 3X, it is definitely more than acceptable for normal use, including printing, without having to reach large print formats. It is also absolutely fine if you use fixed eyepieces with magnification factors from 20X to 35X.

Basic Elements.

The  Light  equipment.
"Light" Equipment?
The basic elements of a kit can be:

1) - A prismatic telescope or a terrestrial telescope on Earth.
2) - An eyepiece of quality equal to that of the telescope.
3) - An adapter between eyepiece and camera.
4) - A camera with 4X zoom up.
5) - A cable release or electronic.
6) - A tripod (tripod) stable and camouflage. (Black or green or camouflaged .. absolutely not to use those aluminum or chrome).
7) - A head with precise movements and fluid. We prefer the video or rocker.

To complicate matters we must always try to remember that all the equipment must be easy to transport and quick installation. .... It is no small thing!

Digiscoping is a collection of various mechanical equipment but also the quality is of prime importance to achieve remarkable results. The balance between the various elements of quality is critical because the end result will always be equal to the poorer quality of the element of the whole. Suppose you have a sound reproduction system consisting of amplifier, player and speakers. All elements have a qualitative value equal to 100 except an element that has a value of 30. Here is the music produced is equal to 30% of the potential of the whole system, indeed, the goodness of all other components will only serve to amplify and emphasize the defects of the one component failing.

There are several ways to match the camera to the telescope. In this article I will consider the method I use, namely afocal.

Afocal Method.

The advantage of the method is that it exploits the afocal magnification factor by summing the eyepiece with that of the camera lens. The result is a powerful telephoto focal lengths that can reach even equal to 3500 mm. but with a significant loss of brightness. This method applies to both compact cars like the SLR. Until a few years ago, with this method, applied only compact machines but the future of Digiscoping see all concentrated in exploiting the system by using the best EVIL or digital SLR (accompanied by a fixed lens, 50mm usually) combined with binoculars even of small dimensions in order to have a system easier to handle. In fact many manufacturers start to produce refined telescopes from 50 mm. ED apochromatic lenses.

When we found the best way to machine and assemble the telescope we are faced with the dilemma of the camera settings for exposure and focus.Working with the focus in manual mode is the most widely used and recommended for the great extension of the research objectives of the MAF. The Olympus, Pentax and Sony have produced targets, including zoom, with all movements within the target body. Unfortunately there are among the brightest, but the advantage of being able to exploit the MAF end, after the one made with the telescope, and really great.the exposure control mode is always best to set it on the spot or, for some machines, in the "Center Weighted." This latest offering is a perfect exposure control 80% of cases. Council, however, to set the machine for a light underexposure (-1 / 3).The control of the priority must be made considering the subject and the characteristics of the light. Our preference is always for the aperture-priority subjects but with very fast and small that we often risking a lot of time on the correct exposure.In our "system", the long focal length, does not give us many advantages over the management of the depth of field managed by the diaphragms.On summer days the sun is much preferable to the choice of aperture priority so that you can also use a lot of time and catch even fast moving subjects.Another thing is the focus. For many it is an issue on which there rages without thinking well the characteristics of the material we have in our hands. We have already said that the choice of the target must move towards a bright and sturdy 50mm.The machine must not be autofocus because the fire we find from the telescope (the only exception being the use of those objectives by all internal mechanism of the MAF). We are very careful to place the focus of the lens of our camera to infinity and do not touch it anymore. With some lenses the focusing ring has a little game or flows past the infinity sign, it may be compromising.The problem arises when, by focusing our subject, who immediately go away, we quickly find the best focus, controlling only in the small viewfinder of the camera that, with a zoom factor too, has darkened.With the new cameras have the advantage of Live View.With normal lenses the mechanical excursion of the research focus is extensive but the pancakes is very low. This fact makes them very handy because we can also use the autofocus. In case this is not the machine that focuses our entire system, but after trying the right focus with the telescope, the machine executes the order. The results are great if our subject is free from objects in the foreground.
