Hmmm... on my X-tender unit, the "hairy" stuff was not really velcro but more of a velcro-type material with an adhesive back.
They are used as "spacers" to make sure that the Fresnel lens is flat (not curved), and applied at or near the end of the flash head to "spread" out the guides so that when the Fresnel lens is stuck onto the guides, its flat. Kinda hard to put into words, but I hope you get the gist.
The vertical/horizontal positioning of the Fresnel is very important as the "focused" beam can affect lighting/exposure if off centre. Test with a normal lens shooting at a wall and adjust the Fresnel lens until the "light spot" is at the centre of the image.

Thats the recommendation.

okay, thanks... just wondering, whats the range of this thing? How do I judge at what distance it becomes ineffective, as in is there a general guideline to using this?
Anyone know if the Night Safari allows flash photography?
