The SE grade meet the critical DayStar quality control criteria applicable in all visual and some photographic environments

The dual dovetail bar can accept both Losmandy and Vixen style bars and the two tightening knobs do not touch the dovetail bar directly

The trade-off at gain 30 is a lower full well capacity at 30

5nm filters are precision-grade ultra-narrowband filters with high transmission at their respective emission lines

QHY42 PRO [MONOCHROME / UV] Sensor:FSI 75) TOA-645 flattener image circleThe QHY42 PRO BSI uses the Gsense400 Scientific CMOS sensor with extraordinary 95% peak QE, 79% UV QE, and very good NIR response, plus an extremely low read noise of 1. 7e . The QHY42 has relatively large 11m pixels in a 2k x 2k array. The sensor size is 22. 5mm x 22. 5mm yielding a good field of view even at longer focal lengths. This camera is ideal for astronomical and biological science research. In addition to the BSI version, QHYCCD also
