Description

I finally got the chance to test the Optolong L-Ultimate filter and I was pleasantly surprised with the results. Shooting with the Radian Raptor 61 and a Canon EOS Ra, I tested with 300s exposures with ISO set to both 800 and 1600. Both produced images with no or very little halo, even with the brightest stars. My first test was on Sadr and then I finished up with 2.5 hours on the Horsehead and Flame Nebulae.
