You can get it in black as Celestron�s �80mm Wide View Spotting Scope� to match Celestron SCTs, from Oceanside Photo & Telescope see below for a photo of the Celestron version.
In North America it is available in three versions which basically only differ in the color of the scope. It is a 400mm focal length f/5 scope that sells for about $200, a very reasonable price (and therefore it is commonly purchased by astrophotographers for use as a guide scope as well). The least expensive and thus very commonly used Short-Tube 80 is manufactured by Synta, the Chinese company which makes most of the refractors sold by Orion and Celestron, and whose scopes are re-badged by many

So keep in mind that the dovetail plate plus camera adapter, and 2D balance weight system are additional expenses if you don�t already have them. It is important to note that you will need to add a 5 pound or so weight below your OTA to achieve dynamic (vertical) balance with any of the rich-field scopes discussed here - see below and the Balancing an SCT page. The rich-field scope then tracks the stars because the SCT�s mount does, and of course it becomes a GoTo scope if the SCT you have is a GoTo scope. Them on a camera adapter attached to a Dovetail Plate on the SCT itself. These scopes include a ��-20 threaded plate at the bottom which is the standard thread for camera tripods, and are intended by their manufacturers to be mounted on a tripod for use. With one of these scopes mounted on your SCT a wide field of view is available when you need it but your SCT retains the narrow field of view necessary for most deep-sky objects.Īlso, a rich-field scope makes a great finder scope when you need to star-hop to find an object (which, even with a GoTo scope, eventually you will do because many interesting objects aren�t in any GoTo scope�s database). They are therefore commonly called �Short-TubeĨ0s� or �ST-80s�. They have very short focal lengths to achieve a wide field of view, and tend to have 80mm-diameter (3�) objective lenses (to keep costs low). Such refractors are specifically designed to supplement your primary scope�sĬapabilities. Therefore many amateur observers mount a small rich-field (wide field-of-view) refractor on top of their main scope. The majority of the objects you want to observe at any given time, require a narrow field of view so switching the focal reducer in and out becomes a real pain, and opens the possibility of damage to your diagonal and eyepieces since you�d be doing this at night in the dark. But it is very inconvenient to remove the items you have on your rear cell, add the focal reducer, and re-mount the rest of the items. You could mount an f/6.3 Focal Reducer on your rear cell, which converts an f/10 scope to an f/6.3 scope and provides you with a wider field of view. Also, when you are observing objects in constellations that are within the Milky Way, you are missing some incredible views of the Milky Way because of the narrow field of view of your telescope. Schmidt Cassegrain telescope advice - rich field scope - Synta ST80Īs I mention on the Nice-To-Have Accessories page, there are some spectacular deep-sky objects (several star clusters and nebulae) that are too large to be really appreciated in a normal scope regardless of how wide-angle an eyepiece you use.
