    Hi, I have a WO Z61 with a Flat 61A adjustable Flattener. How do I calculate the correct backfocus? My sequences are: 1) Z61 + 61A (locked at zero) > M42/M48(16.5mm) > M54/M48(2mm) >ZWO EFW2" (20mm) > 11mm camera ring > 6.5 mm Image Sensor ZWO ASI1600MM Pro = 56 mm. 2) Z61 + 61A (locked at 11.7) > M42/M48(16.5mm) > M54/M48(2mm) > ZWO EFW2" (20mm) > 11mm camera ring > 6.5 mm Image Sensor ZWO ASI1600MM Pro = 67.7 mm. Which one is correct? or neither of them are correct. Thanks in advance!
