Light Pollution from my ezinearticles post

There are three types of light pollution filters: line filters, narrowband, and broadband.

So which one should you buy? Well, to give you a straight answer…it depends. If you live in a highly populated area, you may want to give serious consideration to purchasing a broadband filter. For those who would do well to buy a narrowband or line filter, it depends on what you want to view. Those interested in the details of celestial bodies should seriously consider buying one of these types.

There is little question as to whether light pollution is a problem for the serious backyard astronomer. The good news is that solutions abound, whether you just need to move your telescope or you need to solve the bigger problem with a light pollution filter. There are numerous brands to choose from - Celestron, Meade, and Orion to name just a few. Just knowing that solutions exist can make your viewing experience much less bothersome. Take your time, figure out where you will view the sky, and what you are looking for prior to making your purchase.

The Advanced GoTo Series Telescopes

Marvel at the beauty of the heavenly bodies with the use of an Advanced Series telescope. The Advanced Series offers high-precision and detailed viewing of planets, stars, and other objects from outer space using state-of-the-art technology. Whether you are a novice or an expert, Advanced Series has a user-friendly telescope that makes backyard astronomy fun and easy for you.

About the Advanced Series
The Advanced Series telescope comes in two types: the standard (non-computerized) and computerized GoTo models. It is manufactured by Celestron, a leading company in the optical industry. Celestron was established in 1960 and has since developed and designed high-quality products for amateur backyard astronomers. Their products have been featured in top magazines like PC Magazine, Popular Mechanic, and Popular Science.

Specs and models
Computerized GoTo telescopes were designed with a user-friendly interface for beginners. Computerized models come with heavy-duty German Equatorial mounts and ultra-sturdy 2″ stainless steel legs and center tray for rigidity and vibration dampening.

The Advanced Series comes in four different models:
• Refractor – comes with an aperture from 4″ to 6″.
• Reflector –made for a stronger light-gathering power, which comes with a 6, 8, and 10-inch aperture.
• Schmidt-Cassegrain – a compact instrument with a corrector plate and folding corrector plate.
• Maksutov-Cassegrain – combines two mirrors in a folded design.

Is a Schmidt-Cassegrain for you?

As with any telescope, or any object for that matter, the Celestron 9.25 as a Schmidt-Cassegrain telescope has its advantages and disadvantages. Here’s a review of Celestron 9.25’s advantages and disadvantages as a Schmidt-Cassegrain telescope.

Advantages
1. Very good for lunar, planetary and binary star observing
2. Excellent for terrestrial viewing and photography
3. Closed tube design reduces image-degrading air currents
4. Portable and compact
5. Durable
6. Near maintenance-free
7. Most versatile type of telescope
8. A wide variety of accessories are available
9. Best near focus capability compared to other telescopes

Disadvantages
1. Slight loss of light because of obstructions on the secondary mirror
2. Much more expensive compared to a Newtonian telescope with the same aperture

A review of the Celestron 9.25 telescope shows that, if you’re just starting to get into the hobby, a Schmidt-Cassegrain is a good compromise. It affords you great enough optics with just enough aperture needed for deep sky objects in a compact package. The Celestron 9.25 comes feature-packed, but depending on what suits your needs best, you might want to retain or replace some of its accessories.

The Celestron 9.25″ CPC telescope

The new Celestron 9.25″ CPC SCT offers improved alignment technology and advanced engineering at an affordable price. With the CPC series of scopes with the revolutionary SkyAlign Alignment Technology, it redefines what amateur astronomers look for today. They offer simple and fast alignment, excellent optical quality, GPS, easy to use and setup, great ergonomics, and enhanced computerization at a cost that doesn’t break the bank. Here’s a quick guide to the Celestron 9.25 for first-time users.

Features:

1. Internal GPS - The internal GPS receiver downloads automatically the time and date from orbiting satellites, beaming its location exactly back to Earth; eliminating the need to enter the time, date, latitude, and longitude manually.

2. SkyAlign Alignment Technology - When the internal GPS has already established the telescope’s position, locate and point manually the telescope to three celestial objects. There’s no need to know the stars’ names, and you can pick out even the planets or the moon. The technology then models the sky to figure out the position of every planet, celestial object, and star over the horizon.

3. Operate from a PC - The Celestron 9.25 telescopes include a NexRemote software, which connects your telescope to your computer for image uploading and sharing.
