Its my go-to eyepiece for all objects. I use my 25mm plossl for finding objects, as the zoom suffers from low AFOV at 21mm. Of course, I only use 21mm to center an object for further magnification. its easy to use, and is much more comfortable than a 10mm plossl. Its great on mars, jupiter, and saturn, though you might want to barlow it on planets if you wish. Not only do I use it on the planets, its great to tease out details like spiral structure and other fainter details in deep sky objects.
