Introduction

Review the information below for complete explanations of store layout, basic purchasing information and how to use the indexes.

From the main page of our website you can select JMI Online Store to go to the Product Index of the store.  From there you can select a product.  On the Buy Page you can select a Buy Now link to add a product to the Shopping Cart.  To check out and make your purchase, you can select a View Cart link.  The Next Page link allows you to "turn the page" and cycle through the entire catalog of products, eventually returning to the original starting point.

Important Information

The JMI Online Store is designed similar to a printed hardcopy catalog.  Each page features a particular type of product.  For example, one product page in the store details our Event Horizon focusers.  At the top of each page are five links that allow you to navigate to the home page, back to the previous screen, to the product index, to the next product page or to this help page.  Once you are viewing a product page you can browse through all the information on that page simply by scrolling up and down.

Here is an example of a product entry:

Single-Control Hand Unit JMI MOTOFOCUS, MOTODEC & Focusers HUSC $69 Buy Now Single-Control Hand Unit for JMI MOTOFOCUS, MOTODEC and Focusers The single-control (controls one motor) linear voltage control (LVC) hand unit includes two forward and reverse buttons (red) and a two-position slow-speed switch (black).  The slow-speed switch adjusts from high (left) to low (right).  The system automatically changes from slow speed to fast speed when one of the forward or reverse buttons are held down for two seconds or more.  This effectively gives the hand unit three speeds — very slow (1), slow (1.5 times faster) and very fast (5 times faster).  The system includes a 1/8" jack, quick-stop braking and a 9-volt alkaline battery.  It can control MOTOFOCUS, MOTODEC, EV, NGF and RCF motors.  This hand unit gives the best control of any system ever manufactured by JMI. NOTE The hand unit has two switch-adjustable slow speeds which normally ramp up to a fast speed after two seconds.  Placing the slow-speed switch between the two normal positions (high and low) will cause the speed selection to be overridden and the motor will run at very fast speed (5) at all times.

The information in the blue box on the left summarizes the product. The bold description at the top identifies the product and sometimes the manufacturer and model of equipment for which it was originally designed.  Next is a thumbnail picture which can be selected to see a larger version of that same picture.  Below the thumbnail picture is the part number and price.  This price includes free shipping and handling for shipments within the 48 contiguous states of the continental U.S.  The free shipping and handling does not apply to telescopes (including the reverse binoculars).  Alaska, Hawaii and foreign destinations receive discounted shipping and handling.  The last item is a Buy Now link to add the product to your shopping cart.  See the Terms and Conditions page for important information related to placing an order.  To the right of the blue box is a more detailed description of the product which usually includes a list of manufacturers and models of compatible telescope equipment* and more pictures.

Besides the product entries, at the top of the page you will find several links to related information such as more pictures, definitions, customer comments, frequently asked questions, comparison charts and more.

When part numbers end with an ellipsis (...), the dots are replaced with a code that gives more specific information as to what the product is for.  For example, an NGC-MAX computer complete installation shows a part number of NGC....  The complete part number for an Obsession telescope would be NGCOBS.  You do not need to know the last part of the number since you will be providing us with information on your telescope equipment.  However, you can find this information in document no. 12 in our Document Library (which also shows any requirements and any special pricing).

Specifications that are highlighted in yellow are incomplete and/or uncertain.

Although we have a website shopping cart, we do not immediately process your credit card payments online.  Your card is not charged until your order is shipped (except in special situations such as when a deposit is required).  To place an order, simply select the Buy Now link to add a product to your shopping cart.  Alternately, you can use the printable order form to fax, phone or mail in your order.  The printable version can also be copied and pasted into an email message formatted for HTML.

All prices are subject to change without notice.

* Manufacturers are bolded and listed alphabetically with a semicolon (;) between them, models are listed alphabetically with commas (,) between them and sub-models and sizes are alphabetical/numerical with slashes (/) between them.  Here is an example from our Wheeley Bars information:

Using the Product Index

The JMI Online Store is designed with a page for each type of product or comparison chart.  There are three ways to search for information in the store, the Product Index, the Key Word Index and the Telescope Equipment Index.  The Product Index is a simple "drill down" method for getting to the product pages.  It is intuitive and easy to use and will usually be all you need to access the product information.  Once you arrive on a product page you have access to product definitions, specification, notes and pictures.  Refer the top of this page for information on navigating within, and between, pages and more information on the online store layout and ordering details.

Navigation within the Product Index is easy.  Simply select the link that matches the type of product you are looking for.  For instance, to get to our Event Horizon focuser page from the main index select Focusers then Event Horizon Focusers (EV).  From this Buy Page you can select a product to place in your shopping cart or link to more information.

Within the menus, you can see what level you are at, by looking at the levels shown at the top of the list, and select any upper level you wish to return to.  In the example above, the levels will look like this:

Home > Product Index > Focusers

You can select Home to go to the home page, Product Index to go back two levels to the top of the menu structure or Focusers to step back one level to access all of the available focusers.

Using the Telescope Equipment Index

The Telescope Equipment Index allows you to search for products designed specifically for your telescope equipment.  It is designed to take you directly to those products in the online store.  The top of the list has an alphabetical "shortcut" index of manufacturers.  Selecting one of these companies will take you directly to a listing of the equipment manufactured by that company.  This is a good way to see everything we manufacture for your particular equipment.  At this point you can select a link to a product we make for that equipment.  If you cannot find a particular model, try searching the list by using the search function in your browser (Ctrl F in Internet Explorer).

Please keep in mind that every telescope company has its own methods for naming equipment.  Sometimes the name only identifies the optical tube, sometimes the mount and sometimes both.  When you include multiple design and name changes and hundreds of models, it becomes fairly difficult to be consistent in identifying equipment for which we make aftermarket products.  Therefore, we do not guarantee that our list is correct.  Be sure to check the actual product description before buying.  A good example would be where a particular telescope includes two different options but our aftermarket product is designed for only one of the options.  Some of our products will work with a particular model of equipment even though they were not designed for that model.  As much as possible, we will make note of these situations in the product descriptions (along with slight product modifications that may be necessary to make it work) but not in the Telescope Equipment Index.  It is always a good idea to browse the product description before making a purchase decision.

Once you are in the Telescope Equipment Index, you can switch to the Main Index or Key Word Index by selecting the appropriate link at the top right section of the page.

Using the Key Word Index

The Key Word Index is designed to take you to the correct location in the online store for the product you are searching for.  For instance, our Reverse Crayford Focuser (RCF) has also been known as the Monorail.  Monorail will not be listed in the Main Index but can be found in the Key Word Index.  Selecting Monorail in this index will take you to the RCF page.
