The Lumicon Easy Guider for ZWO Cameras and 2″ focusers is one of the most powerful astrophotography accessories available today, with a large field of view.
This 2″ low-profile Easy Guider features a large pick-off prism, making bright guide-star selection a breeze. It uses telescope optics directly for pinpoint guiding accuracy. This method is superior to using guide-scopes, which can flex with respect to the main telescope.
Benefits of Off-Axis Guiding
• Guiding occurs with the same light path as the imaging detector thereby eliminating the effects due to differential flexure/slop of the auxiliary guide scope.
• Differential flexure in guiding setups often introduces errors far worse than the actual corrections actually needed. Off-axis Guiding avoids this problem.
• Auxiliary guide scopes are blind to image shifting due to primary mirror “flop” in telescopes with moving primary mirrors (SCT’s). Off-axis guiding corrects for this problem
• Guiding occurs at the same focal length as the main imaging camera. Although CCD guiding software can compute tracking errors to sub-pixel accuracy, many guide scope combinations have marginal or too-short focal lengths to be properly effective. Off-Axis Guiding avoids this problem.
QHY16200A Mono Camera, with Filter Wheel and OAG
QHY16200A/IC16200A uses a unique APS-H CCD sensor, a product of close collaboration between QHYCCD and Sensor Supplier .
This sensor is specially designed and manufactured with amateur astronomers in mind who needs mono sensor larger than APS-C. APS-H Format CCD Sensor
The effective image area is 27mm*21.6mm. To compare with the QHY8L APS-C format 23.4*15.8, the APS-H sensor is significantly bigger.
The reason to make such a sensor is due to no such mono sensor between 8300(4/3inch) to 11002(full size).
This sensor is 16mega pixels. The APS-H format is suitable for most telescope and also suitable for 2inch fitlers.
The pixel size of this sensor is 6.0um*6.0um.It silightly bigger than the 8300's 5.4um.
The QE is expected to similar or higher than 8300.
The 37ke fullwell is much higher than the 25.5ke of 8300.
