控制ASCOM CCD摄像机的Python脚本？

Question

我想用ASCOM驱动程序来控制Python中的CCD摄像机，但是还没有找到一个示例脚本来说明它是如何实现的。

我想看看基本控制相机是如何做的-设定曝光长度，开始曝光，下载图像数据。

有人能发布一个我可以使用的示例Python脚本作为起点吗？

import win32com.client
from astropy.io import fits

# if you don't know what your driver is called, use the ASCOM Chooser
#x = win32com.client.Dispatch("ASCOM.Utilities.Chooser")
#x.DeviceType = 'Camera'
#driver = x.Choose(None)

# otherwise, just use it
driver = "ASCOM.AtikCameras.Camera"

camera = win32com.client.Dispatch(driver)
camera.connected = True
camera.CoolerOn = True

openshutter = True # False will take a dark frame
exptime = 1
camera.StartExposure(exptime,openshutter)
image = camera.ImageArray

hdu = fits.PrimaryHDU(image)
hdu.writeto('test.fits')
