I thinking is there any way to make own telescope with help of magnifying glass(convex) and concave lenses arrangement so that we can take photo of space planet like moon, marsh.
I know there are some lenses(200-500 mm) which can take space images. but i’m looking for any cheap way to take space images.
Generally question should be how to make telescope but i also want to know what should be the aperture, exposure and ISO setting for space photo.
