I am upsizing to 2" filters for my new scope, so I don't need this filter anymore.
Purchased from Bintel at SPSP 2005, it has brought me a huge amount of pleasure, especially in bringing out amazing detail in planetary and emission nebulae. It has made deep sky observing from my backyard far more satisfying.
Comes with original Astronomik case, has been treated all times with great care, and is in excellent condition.
Purchased for $190. Open to reasonable offers.
