Rigid Telescopic

Does anyone know where can I buy Telescopic Batons in Singapore?

“Telescopic batons are rigid batons that are capable of collapsing to a shorter length for greater portability and concelability”

It's unimaginable how big the universe is when we look at the sky, starring stars. However, we all know that behind the dark sky is millions discover deep sky objects (DSO). Unfortunately, not all the beauty of the object settings and colors can be seen due to our sense of limitation vision and long distance from our place. By mastering the techniques of photography, digital imaging and astronomy, the beauty of DSO could be discovered and recorded through a photograph. To shoot such asplanet DSO, galaxy, cluster or nebula, but requires a knowledge of the astronomical DSO position in the sky.

Following the rotation of the Earth, the position of DSO relatively no changes, so that the DSO is to remain always in the position where we observe it. Photography DSO Method There are some methods that can be applied to photography DSO, such as camera and rigid mounting stars monitoring. The first is the easiest way to record the beauty of the DSO with wide field of view, using a tripod and wide angle lens with focal length from 17mm to 200mm. You need a camera with manual settings so you can set the duration of exposure. There is a time limit on the duration of exposure in this method to avoid the trail of stars (as a result of relative motion DSO).

Using a long focal length requires a shorter duration of the speed shutter that offers only a small number of recorded data. However, if you want to record track star then you need to have a longer shutter speed, so that the moving object is recorded as a long trail of stars and beautiful. To star tracking method, we use a special tripod mount (German equatorial mount / GEM) supplied with RA motor drive to compensate for relative motion DSO, but first we must do what is called polar alignment. Alignment Polar is a process of adjusting the position of GEM tripod so that its axis is in line with the Earth axis.

It will make the object's position in the viewer the same. This method gives us more room to adjust the exposure long time patiently. Mastering the techniques of photography properly. The photograph on the street does not mean we are not shooting techniques. This is no time in breaking the rules to give a deeper meaning; shooting blur, for example.

So dare to be different. Do not feel inferior, with its tools, in order to register a low light level. The star-tracking method, the camera can be placed in some aspects, such as the camera and lens (all sizes), applied directly to GEM tripod. Camera and lens can be applied on top of the main telescope, so follow the direction of the telescope. This method is called "piggyback". House applies to focus the telescope directly by using an adapter. In this case, the telescope replaces the camera lens.

It is called "primary focus" but only can be done with SLR / DSLR or CCD sensor web cam. House is applied to the rear of the telescope eyepiece via an adapter, so the projected image seen through the eyepiece can be recorded by the camera. This is known as "projection eyepiece. As a tool to help in the observation, we can use a telescope. While the position of the telescope can replace the lens of the camera / web cam (by using an adapter), then you can use for astrophotography.

There are some types of telescopes that are commonly used, namely: Refractor lens as the first optical components. Reflector with a parabolic mirror as collector light. This type of reflex reflector telescope is called Newton, which is the combination of the two, since it has a component of the optical lens and mirror. Performance a telescope is not only measured from the focal length, but also from the size of the aperture – the diameter of an optical component used to collect light. The largest diameter (lens or mirror), more light can be captured and will result in a higher resolution. In the same level of magnification and optical quality same 8-inch telescope will deliver a detailed picture with a higher contrast than the 5-telescope of a meter.

Astro is a challenge, requiring patience, opens a broad vision about astronomy, and can be enjoyed as a branch of photography, and to glorify God for the many natural beauties, even far from where we belong. Just be sure! Even a compact camera can offer as stunning photography.
