Generation 2 True-Balance filters (LRGB2) 1.25" Mounted CRGB (CRGB2-I27R)Astrodon is also providing its latest Generation 2 I-Series 1.25" filters mounted in 31 mm inserts specifically for the popular QSI CCD interline cameras, such as the QSI620 and QSI640. The inserts are also 3 mm tall, matching the filter thickness. Because these filters are so close to the detector without the tall walls of conventional 1.25" filter holders, there is almost no vignetting, even at f/3. In fact, tests have shown that there is only about 10% vignetting at f/2, which can be compensated for with flat frames.
