Borg 2010X2 is a 71mm fluorite

The new Borg 71 FL is out. It can be used with the mini-Borg tubes/accessories as well as the 80mm diameter tubes. The first batch of 100 has nearly sold out already. I lasted all of two days without ordering one.

It's 400mm f/5.6. With the 0.66 DGT reducer, this will be 264mm @ f3.72, roughly 4.8 by 3.2 degrees on an APS-C sensor. With the 0.85 DG reducer, 340mm @ f/4.69, which is 3.7 by 2.5 degrees.
