DBP-EX-48، معزز تباين السديم 48 مم (2 بوصة)

Finally a filter that doesn't introduce coma issues on my RASA. The off-center pre-shift is exactly what I needed for my fast optics, and the contrast boost on emission nebulae is noticeably sharper than my old broadband filter.

Installed it in my HyperStar rig and the off-center pre-shift is exactly what my fast optics needed—the nebulae pop now even in mediocre transparency. Took a single test frame and the difference was immediate; no more fiddling with tilt or spacing adjustments.

Finally got this filter for my RASA setup, and the pre-shifted design made dialing in focus a breeze. The contrast on the Orion Nebula was noticeably deeper than with my old filter.
