Preview whether the Moon, Orion, or the Milky Way core fit your lens and sensor so you can choose focal length before you go out.
Frequently asked questions
Will a 50 mm lens frame the Milky Way core?
On APS-C, 50 mm is often tight. This tool compares FOV with typical target sizes so you can go wider if needed.
Is the Moon always 0.5°?
About half a degree. Almost any lens frames it; the question is how much sky you want around it.
