Wouldn't you know it...the one time I win something at Riverside...I already have one! $90 Lumicon price tag still on the case. Pristine condition though I did put it in my scope once to compare fliter transmission on the Veil Nebula.
Hydrogen-Beta 486nm: 0.1%
Oxygen III 496nm: 94%
Oxygen III 501nm: 95%
$75 w/ $4.50 s/h in CONUS. (SOLD)
Will accept money order or cashiers check although I would prefer Paypal.
Thanks for looking!
