Hi,
As the clouds are still here I'm checking out filters for planetary imaging. Two sets have caught my eye, the Baader LRGB and the Astronomik LGRB type 2c. I suspect they would both be excellent, but am wondering if there are any major differences in performance? I've found an online bench-test type of thing, and noticed that the Astronomik seems to be have more consistent transmission across the colour bands. Is this an important consideration?
I've attached a grab from the test, and here's the link:
