Lumicon 1.25インチ UV/赤外線フィルター - LF3140

The filter threads onto my eyepiece smoothly and really cleans up the false color on bright stars in my refractor. I noticed a much sharper, more natural view of Jupiter last night without that annoying purple halo. It’s a simple accessory but it makes a real difference.

Switched from my trusty old UV filter and the difference in lunar contrast is striking—no more purple fringing around the crater rims. The threading is smooth too, fits snugly on my 1.25" diagonal without any wobble.

Finally got crisp, color-free views of Jupiter through my small refractor with this filter threaded on. The difference is immediate, and it cleans up the blue halos I was struggling with.
