A telescope is an optical instrument designed to observe distant objects in the sky, including stars, planets, galaxies, and other celestial bodies. It works by collecting and focusing light to create a magnified image of the object being observed.
There are two primary types of telescopes: refracting telescopes and reflecting telescopes.
A refracting telescope uses a lens to bend or refract light and bring it to a focal point. The lens at the front of the telescope, called the objective lens, gathers light from the celestial object and focuses it onto a second lens or eyepiece.The eyepiece further magnifies the image formed by the objective lens, allowing the observer to see distant objects in greater detail.Refracting telescopes are known for producing sharp, high-contrast images, but they can be limited in size due to the weight and cost of large lenses.Reflecting Telescope:
A reflecting telescope uses a curved mirror instead of a lens to gather and focus light. The primary mirror collects incoming light and reflects it to a secondary mirror, which then directs the light to an eyepiece or a camera.Reflecting telescopes can be designed with much larger apertures (the diameter of the primary mirror) compared to refracting telescopes, making them more suitable for astronomical observations.They are commonly used in modern observatories and research telescopes due to their versatility and larger light-gathering capabilities.Telescopes can vary in size and complexity, ranging from small, portable models for amateur stargazers to massive observatories equipped with cutting-edge technology for professional astronomers. Advanced telescopes may include features like computerized mountings for automated tracking, adaptive optics for correcting atmospheric distortions, and multi-wavelength sensors for observing various types of radiation beyond visible light.
Telescopes have played a crucial role in advancing our understanding of the universe, allowing scientists and enthusiasts to explore the cosmos, study celestial objects, and make groundbreaking discoveries about the nature of space and time.

If you are looking for a short focus telescope that is compact enough to be carried around on your travel expeditions, then the celestron travel scope 70 will be a good choice. This medium refractor is perfect for use on the go. The package includes a 45 degree correct image diagonal, one 20 mm eyepiece, one 10 mm eyepiece, a finder scope, a tripod and a lens cleaning cloth along with the instruction manual. All these items fit neatly into the backpack and there is enough room to add other necessary items.Easy to use
Celestron travel scope 70 telescope has a fully coated glass lens with a 70 mm aperture. The short focal length (400 mm) allows wider views due to lower magnification for any eyepiece. Objective lenses are placed in a cell that has a dew shield to assist in astronomical viewing. The two-piece lens cap doubles as an aperture stop that helps control the brightness when watching bright objects like the moon. It has a diagonal design that is immensely useful for daytime terrestrial observation as well. images appear clear and sharp with the Celestron travel scope 70 portable telescope.Ideal for lunar observation too
The moon is a favourite celestial body in the galaxy. Celestron portable telescope does an excellent job at spotting the moon with both eyepieces. You can see clear and sharp images with detailing of the lunar surface. And if you wish to tone down the colour, you can always use the aperture mask. As with most Celestron telescopes, you get exceptional imagery while observing star clusters and planets too. This is a compact unit that is complete value for money. Aspiring astronomers can check out the Celestron travel scope 70 price online today.

Estrone (E1), also name oestrone, is a steroid, a weak estrogen, and a minor female sex hormone. It is one of three major endogenous estrogens, the others being estradiol and estriol. Estrone, as well as the other estrogens, are synthesized from cholesterol and secreted mainly from the gonads, though they can also be formed from adrenal androgens in adipose tissue. Relative to estradiol, both estrone and estriol have far weaker activity as estrogens.
Estrone is a white, odorless, solid crystalline powder, with a melting point of 254.5 °C (490 °F) and a specific gravity of 1.23. Estrone is combustible at high temperatures, with the products carbon monoxide (CO) and carbon dioxide (CO2).
