Search Tips and Frequently Asked Questions about Astro-Physics' Web Site

Search tips

This service is provided by
Over the past few years, the Astro-Physics website has grown in both the amount of information offered and the number of products featured. The Google search function, located on the sidebar, will allow you to quickly access product descriptions and specifications, technical support documents and any other information available on our website. It is not possible to search for specific images from our Gallery with Google since they display in a new window. After you type in your keywords, the Google search engine will look through our site, even the PDF documents. The results will display in the familiar Google format.

To enter a query into search, just type in a part number, a product name or any other word and click on the search button for a list of relevant web pages. Since search only returns web pages that contain all the words in your query, refining or narrowing your search is as simple as adding more words to the search terms you have already entered. Please be careful with your spelling and spacing to get the best results.

For best results, it's important to choose your keywords wisely.
  • Try the obvious first. If you're looking for information on a our 155mm telescope enter "155mm" rather than "telescope".
  • Use words likely to appear with the information you want. "apochromatic lens" gets better results than "telescopes with high color-free contrast".
  • Make keywords as specific as possible.
  • Searches are NOT case sensitive. For example, searches for "155edf", "155Edf", and"155EDF" will all return the same results.
  • To provide the most accurate results, search does not use "stemming" or support "wildcard" searches. In other words, it searches for exactly the words that you enter in the search box. Searching for "mount" or "mount*" will not yield "mounts" or "goto mounts". If in doubt, try both forms: "mount" and "goto mounts," for instance.

We suggest using the most up-to-date browsers such as Internet Explorer 6, Mozilla 1.6 and Netscape 7.1. If you are using an older browser some of the features of this site may not work as our designer intended them to. Microsoft Internet Explorer, Mozilla and Netscape are available to download free of charge.  Internet Explorer 6   Mozilla 1.6   Netscape 7.1  

The site also makes use of Java script and requires that scripting support must be enabled in your browser to get the full experience of the site.

Why doesn't my back button work in Internet Explorer?
Our designer wanted to make sure that our menu bar loads on every page no matter how you entered our site. There is only one problem with this and very few of our users ever see it. An error in the way internet explorer interprets javascript causes the browser to constantly reload the page of our site that you entered on when you hit your back button. This only happens if you enter the Astro-Physics web site from a direct URL such rather than There are a few ways around this issue:

1. Click the back button twice quickly and it will take you back to the last page you visited before entering Astro-Physic's web site or click the small triangle next to the back button and select the site you came from.

2. Enter the web site from

3. Use Netscape or Mozilla

Hopefully the next version of Internet Explorer will not have this problem.

The Gallery doesn't work and I cannot see the larger images in the products section?

Our Gallery uses Java script popup windows to display the images and information about them. These scripts have been tested and confirmed to work in Internet Explorer 4, 5, 6 and Netscape 4.x and 6.x.You may not be able to print from Netscape 4.x but all of the popups and information are accessible in these browsers.

Some ad-killer programs such as Web Washer will not allow any pop ups to happen. We recommend you disable the popup blocker of these programs when viewing our gallery and other parts of Astro-Physics' Web Site. Our pop ups are designed to be easily and quickly closed by just clicking on the image displayed. We recommend closing the current image before attempting to view the next one.

If you are still unable to view the popups, it is possible that you have Java scripting disabled in your browser. The Gallery, Menu Bar and Products sections of Astro-Physics' Web Site makes extensive use of Java script and the full effect of the web site will be lost if you have these features disabled. Astro-Physics' Web Site has no third party advertising on our site, nor do we use cookies to track any user on our site. Therefore, there is no need to use ad-killing software while viewing our site.

I am having trouble printing your pages. What can I do to ensure acceptable printouts?

Use Internet Explorer or Mozilla 1.6. These browsers have fewer problems than Netscape to complicate printing. Netscape 4.x for Windows has many printing-related bugs and cannot print pages from our site. Netscape 6 does not have any problems printing or viewing anything on the Astro-Physics web site. If you use Netscape 4.x, please upgrade your browser to Netscape 7.1 or Internet Explorer 6. Internet Explorer 6, Mozilla 1.6 and Netscape 7.1 are free and available for download here.    Internet Explorer 6  Mozilla 1.6   Netscape 7.1 

The site is wider than my screen, forcing me to scroll horizontally. How can I see it all at once?

Nearly all computers sold in the past decade are capable of multiple screen resolutions. Higher resolutions fit more information onto the same monitor, the tradeoff being that each pixel is just a bit smaller. We recommend setting your display to a resolution of 1024 x 768 or higher if you have a 17" or larger monitor or 800x600 if you have a 14-15". This is accomplished via your system's display control panel, rather than within the browser. The more pixels and colors your screen can display the better the images will look. Please read the documentation for your video card or operating system to learn how to change this setting.

The fonts are too small and I can't read the pages?

You need to adjust the size of fonts displayed in your browser.

In Internet Explorer, this is accomplished by selecting the view menu and adjusting the text size.
Astro-Physics' Web Site works best with a medium font setting.

In Netscape this is done by going to the view menu and adjusting the text size.
Astro-Physics' Web Site works best with a 100% font setting.

Large and smaller font sizes may be used but the formatting of the page may change.

I am using Netscape 1.1 and your site does not display properly

This site takes advantage of some of the more recent developments in web design such as frames, tables, Java script and rollovers. Older and nonstandard compliant browsers will have trouble with these features. We strongly suggest you upgrade to Internet Explorer 6, Mozilla 1.6 or Netscape 7.1.   Internet Explorer 6   Mozilla 1.6  Netscape 7.1 

I have a question about your Web Site that is not covered here. Where should I write?
