This brand new QUARK optimized accessory is designed to fit Daystar's classic Combo Quark Hydrogen Alpha Filters (Chromosphere or Prominence models). The 4.3X barlow is one of two options for Daystar's new truly telecentric, fully baffled, custom engineered and Quark optimized barlows that enhance the performance of the filter. Use the 4.3X telecentric barlow by unscrewing the silver snout from the Combo Quark and screwing on the barlow.
For refractors from F/5 to F/9 you have a choice of the 2.8X (sold separately) or 4.3X telecentric barlows. This 4.3X barlow will show full disk with approximately 480mm focal lengths or shorter. The filter performs better with a narrower bandpass with the 4.3X barlow, prioritizing surface contrast at the expense of a dimmer image as compared to the 2.8X barlow. We encourage experimentation to determine which setup best meets your goals.
