iOptron LRGBイメージングフィルターキット -1.25"

Swapped out my old filters for these LRGB ones and immediately noticed sharper color separation in my nebula shots. The 1.25" size fit perfectly in my filter wheel, and the coating seems to cut down reflections nicely.

The transmission curves on these filters really bring out subtle nebula details that my old set completely washed out. I finally got clean, separate layers in my M51 image after struggling for months.

The color separation on these is noticeably crisp, and the coatings are clean without any haze. I’ve been getting much sharper blue channel data in my narrowband workflow.
