Zhumell 1.25" O-III Filter
If you like emission nebulae, (and who doesn't?) I highly recommend you get one of these filters! This one fits into the bottom of most 1.25" eyepieces. You get up to 6 TIMES more contrast!! For example, If you look at the Veil nebulae in a very dark sky you might barely see it without this filter, but after you put this filter in, it will be seen much more easily! NOTE: these filters do NOT WORK on galaxies, reflection nebulae or star clusters, ONLY emission nebulae.
Note: Works best with fast telescopes, F6 and faster
This is a great price you will find an O-III filter!
