The tracking mount I use for wide field astrophotography is the Kenko Skymemo R. This is a tracking mount specifically designed to carry one or more cameras. Luminous I usually like to use the two prime lenses for simplicity in focussing and better image quality than the kit zoom. Dark Frames are images with the lens cover on and are shot for the same duration of the light images. Exquisite prime focus close-ups of galaxies and faint nebulae are attractive showpieces, but the art and technicalities of photographing such objects through a telescope are intimidating to the beginner. According to a website I believe it’s a 9.9 degree field of view. The amount of motion is not noticeable when using the telescope visually, but in astrophotography, changing the focus may move the target entirely out of the camera’s field of view. Perhaps it would be sensible just to clarify what you mean by "wide field" here. Since all the controls are on the camera itself, you don’t need a computer in the field.

If you are doing astrophotography without go-to and with manual sighting through star-hopping then, at least as a beginner, you should either stick with target objects that are bright enough to see in the finder from your site and use star-hopping with the finder; or use one of the available techniques to have an eyepiece available on your scope and star-hop using the eyepiece. Categories: Astrophotography Calendar. If you follow my blog, you know that I’ve begun photographing more wide field targets. If you want to zoom in on the target, you just need to increase the focal length of your telescope. I often call it poor people’s large format camera.
