This full-frame photographic field flattener is designed for the Stellarvue SV80ST. It threads directly onto the Stellarvue or Feather Touch 2.5" dual speed focusers. Simply remove the 2" adapter on the focuser and thread this on. This flattener significantly improves flat field performance when imaging with DSLR or CCD cameras. With its over-sized 48 mm t thread it has far less vignetting than the SFF6 flattener which uses a smaller and more restrictive 42 mm t-thread. Optically, it is designed for any size ccd chip up to full frame size.
This field flattener requires 55 +/- 0.5mm (standard DSLR) back focus. When using a CCD camera, the remaining back focus required can be made up with 48mm extension tubes. SKU:SFF3-80Width:6.00 (in)Height:6.00 (in)Depth:6.00 (in)Shipping:Calculated at Checkout

Processing time is the time it takes from when you submit your order to when the product leaves the warehouse. The "Ships Within" time frame listed with each of our products on the website applies to this time frame. For example, if your order a product that reads "Ships Within: 2 Weeks", this means that the product typically leaves the factory within two weeks. If there will be any additional time required to process your order, we will notify you immediately to confirm the delivery period. This time is needed for products that are shipped to you directly from our manufacturers. The manufacturers need this time to fulfill your order. In some cases, the items are custom built. Shipping time is measured when your order leaves the warehouse to when it arrives at your address. Actual shipping time can vary between 2-5 business days.
