Back Focus Calculating
The Full Frame Flattener has approximately 5 mm of adjustability. The adjustment distances listed below assume a starting point of 55 mm, the standard thickness of a DSLR with a T-Ring. As a result, if you opt for an astroimaging camera instead of a DSLR, you will need spacers to reach 55 mm of back spacing. Next, simply adjust the flattener to accommodate the 60EDR or 72EDR.
| 60EDR Flattener Adjustment: 3 mm |
| 60EDR Total Backfocus: 58 mm (55 mm + 3 mm) |
| 72EDR Flattener Adjustment: 1.5 mm |
| 72EDR Total Backfocus: 56.5 mm (55 mm + 1.5 mm) |
