Hello, what is the approximate magnification of this astro camera, and how can it be changed?
Will small deep-sky objects fit in the frame? I'm just a beginner and have no one else to ask.
An astro camera is essentially just a piece of sensor of a certain size—the larger the sensor, the wider the field of view. My camera, the ZWO ASI662, has a small sensor, which is why this galaxy fits entirely in the frame. The actual magnification depends on the telescope's focal length; mine is 650mm. If you use a telescope with a 1300mm focal length, you would magnify the galaxy further, and it might no longer fit completely in the frame.
