If you want to observe insects on flowers, you could use a telescope
with a long range focussing system.

You can also place a pair of binoculars in front of an inverted
objective placed at the focal lenght of distance from the sample.

In order to observe melted metals, in metallograpy are used parabolic
objectives which are able to form the image of the sample at some
centimeters of distance and with a magnification of 1. This image is
then magnified by the microscope in the usual manner.
