TOUPTEK LARGE OFF AXIS GUIDER
ToupTek
TOUPTEK LARGE OFF AXIS GUIDER - M54 OAG is backordered and will ship as soon as it is back in stock.
The ToupTek Large Off-Axis Guider features a large 10 x 10mm prism and a variety of connection methods. For telescopes with long focal lengths, a guiding camera with a large sensor is recommended such as the SC2210M.
The ToupTek Large OAG can be purchased with your choice of either M48, M54 or M68 connection plates on the telescope side. The overall thickness of the OAG is 17.5mm.
The main purpose of an off-axis guider (OAG) is to use the same optical path as the main camera when guiding during astrophotography. Using an OAG avoids the problem of differential flexure that can occur when using a separate guide scope. With an OAG, part of the image is picked-off from the edge of the imaging circle which does not block the main CCD. Off-axis guiding provides more accurate guiding and sharper final images.
