AmScope A20X-V300 Finite Achromatic Biological Objective Lense with 20X Magnification and 160mm Tube

Budget 20x DIN objective is an excellent addition for observing pond life

Perfectly compatible with vintage Swift 3200 series compound 'scopes. Surprisingly good optical performance for such a low cost. Rapid shipping was also a delight. Was a bit sad to see its plastic container had some cracks and stripped threading on the lid. Otherwise, transaction exceeded expectations.

Microscope Objective for Astronomy

This is another objective I use for imaging planets thru my telescope. Use the microscope objective to image the telescope primary focus, and adjust to focus a greatly magnified image on camera sensor.

Great eyepiece

Nicely fills the magnification gap in my previous set of 4x, 10x, 40x, and 100x.
