Zhumell 1.25" O-III Filter

Brand new!

 

   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!
