Lumicon Cassegrain easy guider

One of the most powerful astrophotography accessories on the market today, greatly extending the photographic capabilities of your Schmidt-Cassegrain telescope.

The sturdy Cassegrain Easy-Guider features a unique, patented, radial adjustment for finding bright, off-axis guide-stars. The Lumicon Cassegrain Easy-Guider also includes rotational adjustments, along with a large off-axis prism, both of which combine to simplify guide-star selection. The multi-coated, 50mm focal reducing lens yields 100% edge-to-edge field illumination, high-contrast, and pinpoint star images across a 35mm frame. The reducing lens in its standard position provides a 0.65 reduction (F/10 optics become F/6.5). It can also be moved farther from the camera, yielding an approximate F/5 ratio. Exposure times with the Lumicon Cassegrain Easy-Guider are thus 2 to 4 times shorter, and the image size is correspondingly reduced.

Note: The following accessories are required for photography: A prism diagonal; a guiding eyepiece (or auto-guider); and a camera-specific T-ring. These may be user-supplied, or purchased separately. See accessaries below

Lumicon easy guider for Newtonian and Refracting telescopes

The low-profile Lumicon 2in & 1.25" Newtonian/Refractor Easy-Guider is one of the most powerful astrophotography accessories available today. The Lumicon Newtonian Easy-Guider incorporates a unique, patented, radial adjustment for finding bright, off-axis guide-stars. It also features rotational adjustment, along with a large pick-off prism, both of which help to make bright guide-star selection a breeze. The LG1015 drops into 2" eyepiece holders, and uses your telescope's optics directly for pinpoint guiding accuracy. This method is superior to using guide-scopes, which can flex with respect to your main telescope. The filter compartment is located past the pick-off prism, on the camera side of the Lumicon Easy-Guider. This allows you to guide with unfiltered starlight.  The compact design of the Lumicon Newtonian/Refractor Easy-Guider allows for installation in seconds. The 2" Newtonian/Refractor Easy-Guider requires 0.85" of "back-focus .

Notes: For use with SLR cameras; digital imagers may require an extension piece. The following accessories are required for photography: A guiding (reticle) eyepiece (or auto-guider) and a camera-specific T-ring. See accessaries below

Lumicon 12mm illuminator eyepiece

The Lumicon 12.5mm Orthoscopic Eyepiece with Illuminated Reticule is a state-of-the-art guiding eyepiece, featuring rheostat brightness control and on/off switch. The cross-hairs are fully focusable for precision guiding. Black anodised to prevent light reflection.

Lumicon Coma Corrector

Dramatically reduces coma (flared star images) in f/3.5 to f/6 Newtonian telescopes. Optimised for photographic use, it may also be used visually.
The Lumicon Coma Corrector is an afocal, or 'zero-power' air-spaced doublet lens system and is fully multi-coated on all 4 surfaces to prevent ghosting. The aluminum cell's 48mm (2") threads can be used on all 48mm threaded accessories.
