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.
