thats a bit far but for what you get its worth every cent. actually after seeing this im going to layout my setup with lots of more room for the reds in case i want to combine 2 reds with correction optics. with that long of a FL could you only need one set of dr.lava lenses? just send them threw the pbs then into them? as long as you use a wave plate right? to keep the beam pattern the same? that could lower the cost a good amount.
