Lumicon 2" UV/Infrared Filter - LF3145

Switched to this 2" filter for my planetary imaging and the difference in contrast is immediately noticeable—the IR cutoff really cleans up the red halos I was getting before. Threads onto my focuser smoothly and doesn't add any unwanted star bloating.

Finally got this filter for my astrophotography rig and it noticeably sharpened my bright star images on the refractor. The coating seems to do exactly what it's supposed to.

Bought this strictly for my reflector to clean up my nebula captures, and the IR cutoff makes a real difference in star color balance. Screws into the 2" focuser without any play, and the glass is clear with no reflections I can see. For the price, it’s done exactly what I needed for imaging.
