Description
Explore Scientifics 3 Field Flattener .7x Focal Reducer is a multi-faceted accessory designed to enhance your astrophotography experiences.
The Explore Scientific 3″ Field Flattener/.7x Focal Reducer is designed to increase your photographic enjoyment of your Explore Scientific refractor. Depending on which refractor you own, you might need an additional adapter. Out of the box you will be able to attach it to the 3″ Explore Scientific focuser. However, you will need the #510366 adapter if you have the 2.5″ Hex focuser, or the 510364 adapter if you have the 2″ Explore Scientific focuser, to attach this piece of equipment to your scope.
Once installed you should notice a few things. 1. The stars are pinpoint out to the edge of your camera, no more curvature. 2. You will notice more sky in your field as you have reduced your f/ratio by .7x. And finally 3. Your exposure times will have decreased and your images will be brighter due to the faster optic.
Explore Scientific has thought of everything. The device is fully multi-coated to help maximize light transmission, and it also comes standard with adapters to help your camera/DSLR/CCD attach.
This piece really works well from f/8 to f/7.5.
