The SBIG OAG-8300 Off-Axis Guider is an accessory for the ST-8300 and STF-8300 series of cameras. It may be used with or without a filter wheel. The OAG-8300 is designed to allow guiding on stars off-axis from the imaging CCD using an ST-i camera as the autoguider. Its internal 7-element optical relay system includes 0.7X focal reduction so that the field of view of the guider is effectively doubled, increasing the odds of finding a bright guide star without compromising the centering of the target object on the ST-8300.
