Spectral Transmission

Spectral Transmission Chart
Yellow line is published transmission. Color fill is my independent verification with the filter I tested. Note: I used a Quartz Tungsten-Halogen bulb which is broad spectrum, but does not have good throughput in the blues hence I only vouch for the accuracy of my independent verification from 500-900nm.

Purchase from:
  1. I have now spent over $450 on the Baader, having purchased it 3 times. That’s how good it is. The first one took a tumble onto concrete with an Altair Hyperstar. The second one got so lodged into a DSLR WO Redcat adapter that I finally had to sacrifice it. I’m hoping 3 is a charm. Excellent filter!

  2. You know, I discounted this filter as being primarily for visual observation and not for astrophotography, but after seeing your results here I’m going to throw it into the mix of filters I’ve had for a while (Astronomik UHC, IDAS LPS D-3, and the Baader M&SG) and do a few comparisons. Maybe it will work out well!
