这是我在GrandMesa天文台上处理的最新数据集。
由于恰逢满月，这是一个合乎逻辑的测试目标。这是我第一次使用这个新的QHY168M Mono 单色CMOS相机，也是我第一次在12寸RC上使用Optec Gemini的Focusing Rotator。我很快会对这个调焦器做一个介绍，但不用说，它确实是一个很好的调焦器。
QHY168M是非常流行的QHY168C的单色版本，并被送到GrandMesa天文台进行测试。我对目前的结果印象非常深刻，它使用了1600万像素的索尼IMX071 APS-C格式传感器，分辨率4952x3288，有4.8um x 4.8um像素。对于过滤轮，我使用的是QHYCFW2-M，配置36mm无框Optolong滤镜。因为相机是基于QHY168C的，它没有单色相机常规接滤镜轮的4引脚插口，连接是通过一个USB，用Ascom RS232驱动直接连接PC，在最初使用RS232驱动程序时我遇到了一些问题，但是最新的驱动程序运行良好，除了在TheSkyX中使用，我相信QHYCCD和Bisque正在努力解决这个问题。
QHY168M相机的灵敏度给我留下了深刻的印象，在第一次测试中，我选择了gain 4和offset 30，数据用偏置、暗、平场进行校准，经过预处理并结合到Pixinsight中，在Photoshop CC中进行后期处理。

The Great Globular Cluster in Hercules M13
This is the latest data set I have processed fromGrandMesaObservatory.com
As the moon was almost full it was a logical target for this test. This is
the first time I have used this new QHY168M Mono CMOS camera and also the first time I have used the Optec Gemini Focusing Rotator on the 12" RC.
I'll be doing a review on the Gemini shortly but needless to say it really is a great focuser.
The QHY168M is essentially a QHY168C One Shot Color camera that has been converted to Mono and sent to Grand Mesa Observatory for testing. I'm very impressed with the results so far and It uses a 16 Megapixel, Sony IMX071 APS-C Format sensor 4952x3288 with 4.8um x 4.8um pixels. For the Filter Wheel I am using the QHYCFW2-M with 36mm un mounted Optolong Filters.
Because the camera is a converted OSC it does not have the regular 4 pin
filter wheel connection, instead the connection is made via a single USB
cable directly to the PC using an Ascom RS232 driver, I had some problems
initially with the RS232 driver however the latest driver works very well
except if trying to use in TheSkX. I believe QHYCCD and Bisque are working hard to resolve the driver issues with TheSkyX. I am very impressed with the sensitivity of the camera and for this first test I selected a gain of 4 and offset of 30, the data was calibrated with Bias, Dark and Flat Frames, Pre Processed and combined in Pixinsight, Post Processing in Photoshop CC.
