Before DSLR prices dropped about 8 years ago, amateur astronomers were using compact digital cameras with fixed lenses like this. I never did any myself but I think they used to (maybe still do) sell T thread to filter thread adapters. You can also use these eyepieces for regular eyepiece projection. The eyepiece projection method can make it possible to project an image from an instrument with insufficient back focus for prime focus or use with a barlow or teleconverter.
For pictures of the Moon, it is possible to do afocal hand held. I recall taking some images of Venus this way a long time ago. Anything fainter would be difficult.
