Heart of PST transmission

I put the PST etalon module and the PST BF5 together, I found the transmission was quite high, by high, I mean I can see terrestial targets through this combination.

Sounds like the ERF of this older version is in the objective.

The high transmission could probably mean it's even more suitable to be used with a Herschel Wedge, let's see.
