A lantern simply is a portable flashlight case with transparent sides to give to allow the light to be spread around the lantern 360 degrees unlike the spot-bean of the regular flashlight, it is like you taking a living room lamp with you.

Barlow Lenses and Focal Reducers

Simply, it's a concave (negative) lens placed between a telescope objective and eyepiece to increase the magnification, usually by two or three times. The negative lens reduces the angle of convergence of the light cone, effectively making it appear to the eyepiece that the primary has a longer focal length. It was invented in the early1800s by English physicist Peter Barlow (1776–1872)

Eyepieces for Telescope

What is the Eyepiece

The eyepiece is the lens assembly at the focal point of the telescope that forms and magnifies the image. Most telescopes, even department store types, come with at least one for initial use. Sadly today many of the major manufacturers deliver their telescopes with just that one eyepiece. Today’s Celestar 8 and Nexstar 8 telescopes,the current editions of the legendary Celestron C8, come with only a single 25-mm Plossl eyepiece (though Celestron does offer a nice observing kit that adds five more eyepieces and a filter set for under $100).

Panasonic unveils first handheld 3D camcorders

The camcorders look like regular handy-size video cameras and can capture conventional 2D video and images, but by adding a conversion lens adapter, they can capture in 3D. The adapter has two small lenses that each capture a slightly different image of the scene being shot. The right-eye and left-eye images are recorded side-by-side and are what's needed to create a video image with the illusion of depth.

iPhone App: SkyVoyager

SkyVoyager is a powerful astronomy app for the iPhone, iPad, and iPod Touch. It is designed for both beginners and advanced users. It contains a database of 300,000 stars to 10th magnitude, and 30,000 deep sky objects, including the entire NGC and IC catalogs. It renders the planets and moons in detail, using NASA mission imagery, and includes a database of several hundred asteroids, comets, and artificial satellites.


iPhone App: iStellar

iStellar is a mobile planetarium and astronomy app for iPhone and iPod Touch. Based on the time and location setting input by the user, iStellar able to display the stars on the night sky for the given location. Information obtained through the GPS function, iStellar will chart the location of stars and will rotate according to the position detected by the position sensor. It is optimized for Multi-Touch control, allowing you to operate intuitively; drag to move the star chart, pinch to zoom in and out, and so on.

Low budget Astrophotography


Astrophotography may sound to be a huge step for beginners and is only reserved to professionals who spend years and years in this hobby and with quite expensive gadgets. As a matter of fact it needs good experience, but you will educate yourself with trial and error time after time, but to be honest, it's very tricky and maybe impossible to have results like the powerful high-end imaging devices, especially when imaging deep sky objects, but with cheaper equipment you can create decent images if you know how to tweak'em to the limits, now we will see how it's done.

Starter Telescope Models for Beginners

What to consider ?

There are a wide rang out there you can pick from. And I will try here to review and show you some of these models which are recommend for a beginner, compared to the cost.


Buying a Telescope for Beginners

So, you intend to buy a telescope, my belief that there are three primary concerns a beginner should have when buying a first scope: cost, size (& type), and reliability. Those three aspects are very common when you decide to buy whatever you put in mind, so we will try to follow them from a amateur point of view or just a father who want to get his son the scope he always dreamed of.
