Imaging Deep Sky Objects

Capturing impressive images of deep sky objects, such as galaxies, nebu- lae, and star clusters, require long exposures. You will take several individual images and stack them together to form one high-quality resultant image, just as you would with planetary imaging. But while planetary images are formed by stacking many exposures of less than 5 seconds, deep space images will generally be comprised of individual images of a minute or longer!

Note that the StarShoot Pro is also capable of capturing planetary images. To increase the image scale of the planets, a barlow lens is recommended. See “Tips – Using Focal Reducers and Barlow Lenses”.

Very accurate polar alignment is essential for deep sky imaging. Stars will streak across the field of view without precise polar alignment and tracking. Longer exposures of 60 seconds or more also require autoguiding with a separate camera. The Orion StarShoot AutoGuider can be operated with the StarShoot Pro in MaxIm DL Essentials.

To start:

1.Acquire and center the deep sky object into the field of view of your eye- piece. If you are using a mount with an accurate computerized go-to sys- tem, you can keep the camera installed in your telescope’s focuser without using the eyepiece.

2.Remove the eyepiece and replace it with the StarShoot Pro.

3.Set the Mode to Light Color 1x1 and precisely focus the camera by using the telescope’s focus knob and the Focus setting in the Camera Control Window. If necessary, move the telescope to a nearby star to determine the best focus. (Refer to “Focusing”)

4.For best results, set the Mode to Light Raw 1x1 after you have reached focus. Use the Medium setting in the Screen Stretch Window
