![]() Both methods proved to be to inaccurate to be really useful. You can do this basically in two ways putting the laser alongside your lens or pointing the laser in the viewfinder. I got the advise from someone to try and use a green laser to get a better understanding of where the camera is exactly pointing at. I found this to be quite hard so I wanted to have a more easy and accurate way of doing this. When using my Nikon D7000 on the Astrotrac I used to aim and frame by just ‘looking over the lens’ and taking lots of test images and comparing the image to the star chart of the atlas. Comparing it to a star chart can be done when you know where you are pointing at generally, but if you are off target it is very hard to see ‘where’ you are and how to adjust. This makes it a bit more easy, but you still only see the brightest stars in a relative narrow field of view, depending on the focal length of the lens you are using. To see exactly what your camera is seeing you can make use of the liveview feature of your camera nowadays. ![]() In many occasions you probably are using a DSLR for astrophotography on a mount that doesn’t have GoTo, so you have to find and frame your target manually.
