用于控制ASCOM CCD摄像机的Python脚本

Question

我想使用ASCOM驱动程序在Python中控制CCD天文摄像机，但还没有找到示例脚本来显示其完成方式。

我想看看如何完成相机的基本控制 - 设置曝光长度，开始曝光，下载图像数据。

有人可以发布一个示例我可以用作起点的python脚本吗？

Answer 1

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')
