It’s ideal for guiding long-exposure astrophotographs with short to medium focal length telescopes up to 1500mm focal length. Its bright, wide-field optics serve up lots of potential guide stars on your autoguider’s CCD sensor, and it’s small enough to stash in an accessory case!

This focuser is intended for use with 6" to 12" aperture Newtonian reflectors. If you do not have a Newtonian reflector, the focuser may not be appropriate for your telescope. Crayford focusers generally perform better than rack-andpinion models because th

Each session with your telescope will be a learning experience. Each time you work with your telescope it will get easier to use, and stellar objects will become easier to find. Take it from us, there is big difference between looking at a well-made full-color NASA image of a deep-sky object in a lit room during the daytime, and seeing that same object in your telescope at night. One can merely be a pretty image someone gave to you. The other is an experience you will never forget! A. The Moon W

The motor drive system also features a push button hand controller that can move the telescope along the right ascension (R.A.) and declination (Dec.) axes at speeds of 2x, 4x and 8x the sidereal rate.This provides an easy way to center objects in the eyepiece. The Dual-Axis motor drive system is also necessary for doing long-exposure astrophotography.The electronic hand controller allows positional corrections to be made to both the R.A. and Dec. axes of the mount during an astrophotographic ex

A 05/10 Congratulations on your purchase of an Orion Deluxe 100mm f/6 optical tube. Your telescope has been designed with high quality precision optics and excellent mechanical construction. The linear bearing dual-speed (10:1) Crayford focuser will make getting sharp images a breeze and reduce image shift to almost zero. The intermediate f/6 focal ratio will show only moderate color fringing. Your new telescope is versatile enough to also be used as a guidescope. These instructions will help yo

You keep both eyes open when looking through the EZ Finder II, which makes it easy to compare the view through the sight with the wider naked-eye view. EZ Finder II has a wide 10° field of view, with a variety of options for attachment to your telescope, as well as adjustable brightness control. Parts List 1 EZ Finder II 1 Dovetail mounting bracket 1 Universal mounting base 1 Double sided foam tape 2 Flathead screws 2 Lock washers 2 Hex nuts Installation First, open the box and make certain that

Different processes and structures within celestial objects emit light of varying color. Certain features and details will seem to “pop out” of objects when viewed or imaged with wavelength- specific filters. The Orion LRGB filter set allows you to isolate red, green, and blue light for imaging purposes. Additionally, the full-spectrum luminance filter adds superb image resolution to the process. All Orion LRGB filters have been made to cut out infrared (or IR) wavelength light which can detract

Celestial objects such as nebulae and galaxies look very different when observed or imaged in specific colors of light. Different processes and structures within celestial objects emit light of varying color.

. . . . . . . Figure 1a. Congratulations on your purchase of the Orion Deluxe Off-Axis Guider. This useful imaging accessory enables you to image and guide through the same telescope, thereby eliminating the need for a separate guide scope which also saves weight on your mount. The Deluxe Off- Axis Guider is especially useful for Schmidt-Cassegrain telescopes or other systems that are prone to optical flexure or mirror shift. Since the autoguider detects the exact same movement as the imaging ca
