QHY 5-II系列CCD使用手册
QHY 5-II系列CCD使用手册
图1:晴朗夜晚天空背景的归一化光谱(地点:美国圣巴巴拉) 图2:有无弦月的天空背景的对比 天空背景 对于大多数用户而言,天空背景是夜光和人造光的混合体,而月亮也会随着波长的变化改变能量的分布。我使用成本不高的QHY5L-II-M相机构建了一种基于衍射光栅的低成本光谱仪,以测量此背景,并得出以下结果。图1显示的是从...
拍摄参数:裕众130 APO PRO+QHY533M+ AZEQ6 PRO+QHY 5II-L-M 累计曝光:2.5小时 总结 手中的这台QHY533M虽说是工程样机,但完成度出乎我的意料,硬件做工保持了QHY一贯的高水准。通过这段时间的测试,这台相机各方面表现良好,我对它十分满意。在我体验这段时间里,使用这台相机进行了月面、...
The 1.25" barrel is not used with the QHY5-II/III cameras when connecting to the Mini Guidescope. Here is a picture of the front of the camera. All of the 5-III's look the same. What you see is the 1.25" adapter (black) connected to the blue camera body. The QHY images for t...
Specifications: Model: QHY Mini Guide Scope Diameter: 30mm Focal Length: 130mm Aperture: 1:4.3 Object Lens Type: Doublet Focus System: Front Side Focuser Camera Interface: C/CS Mount Compatible Cameras: QHY5II and QHY5III series Anti-Scatter Light Matt Paint: Yes, Internal painted Weight (OTA...
我使用成本不高的QHY5L-II-M相机构建了一种基于衍射光栅的低成本光谱仪,以测量此背景,并得出以下结果。图1显示的是从我的后院拍摄的暮色、夜空和弦月夜空的归一化(峰值)光谱。光污染还算不错,在这样的夜晚,我通常可以看到五等星。垂直轴是归一化的计数,没有针对量子效率进行校正,但是它用于天文探测,因此比较具有...
Pro II–Based on Pro I models, it provides another two CameraLink interfaces. M–Monochrome. C–Colored. L–Lite version is only available in PH Grade. Its body length becomes shorter and the built-in memory storage is 1GB instead of 2GB. Mono only. SBFL–has a shorter back focal length...
As a member of QHYCCD's high pixel counts CMOS camera, QHY163M/C has a built-in 128MB DDRII image buffer. The generous buffer helps facilitating large image transfer, preventing frame lost after long exposure while transferring and allows the camera to run smoothly when used wit...
