The rule of thumb is that if you photograph something close to the meridian, the rotation of the field is higher. In some cases, you can take more than 30s exposures. The altazimuth mount is not compensating for each sky movement, so if you track the object long enough, you will see that the object rotates. The exposure limit is caused by the field rotation. The 30s exposure is good enough to take some nice pictures even in medium-polluted skies. You are going to be limited to a 30 to 60s exposures depending on the position of the object on the sky. But it can be done with an altazimuth mount too. For astrophotography, it’s recommended to use equatorial mount because you can take long exposures with it. Manual mounts can be upgraded with a step motor that tracks the object, and it is even cheaper, but you will have a hard time to find deep space objects on the sky with it. GoTo system will find every target automatically, and it will track the object during the shoot. Telescope Mountįirst, we need the GoTo mount, not a manual one.
