Is the improvement really that noticeable after applying flocked light trap material?
On bright planets like Jupiter and Venus, you should be able to easily see an improvement in field glare surrounding the planet (assuming your original condition was a simple painted tube wall). Contrast on the moon is also noticeably improved. The improvement is more subtle on deep space objects, though the flocked paper does a good job at reducing glare from nearby bright objects like streetlights, house lights, etc.
