The Apertura 0.5x Focal Reducer provides you with a considerable reducingfactor in a wide variety of setups! This is thanks to its generalizedmulti-coated two element, correction-less, design which can provide simpleimage circle compression with most telescopes; rather than the model ortelescope design specific approach other reducers follow.This enhanced compatibility gives you the freedom to expand your astrophotography horizons and discover new perspectives for your gear, without rigid scope or spacing requirements! Connect your camera with around 50 mm of backspacing to experience a 0.5xfocal reduction that will greatly reduce your exposure time and vastly expandyour field of view, or experiment with additional spacing to increase thefocal reduction effect even more! This speed boosting effect comes from thecompression of your optics’ image circle, which makes this well suited forsmaller sensor cameras or with image cropping—especially if youplan on pushing the reduction factor!

0.5X Reduction
This focal reducer features a 0.5x reduction factor with your gear installed around 50 mm. This provides an incredible 50% reduction in effective focal ratio, dramatically increasing the field of view by effectively reducing the focal length of your telescope and brightening the image reaching your camera sensor. This can turn a moderate reach 1000 mm focal length f/9 telescope into a wide 500 mm f/4.5 astroimaging setup! The optical design achieves this feat by compressing your telescope’s image circle. This is done without adding any correction, making this accessory well suited for smaller sensor cameras and a wider variety of telescopes than some other reducers. This also allows you to experiment with spacing to compress the image circle even further for an even brighter image. With a design conducive to tweaking, adding this accessory to your imaging train is an excellent way to expand your horizons and open up exciting pathways for exploration in your own astrophotography journey!
