I like the Nydar sight's use of ambient light for the reticle, requires neither batteries nor LEDs (which weren't invented yet in 1947, anyway).For birding purposes, I wonder how well the sight works if you're in a hide (a low light situation), spotting birds in bright sun outside?From my LED-illuminated sight, I know that outside brightness can overpower the red LED even at highest level, while the green LED is still visible. (I believe the human eye is most sensitive in the green band. There might be an efficiency difference in LED output too, but I haven't checked this.)Obviously, with the Nydar using all available light, reticle colour is not a limiting factor <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />With regard to the ball head mount, how difficult is it to align the sight with the scope? A weakness of my test rig is that it has no mechanical alignment built in, and a ball head allows freedom of movement in all directions, which I'd think might make "trueing" the sight difficult. However, if you're using it successfully with 90x magnification on the Pentax, it obviously can't be so bad! <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />Regards,Henning</blockquote>
