M-27

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.

Okay, thank you. And what shutter speed did you use?

This is a live stack through ASI AIR, about 20 minutes if I'm not mistaken.
