Very fast
Nice selection of in-stock items which are backordered elsewhere. Shipping was very fast and secure. Thank you!

LP Filter
Arrived on time in good shape. Performing excellent on the Ghost of Cassiopeia and Iris


My favorite broadband / light pollution filter
Works great in for broadband targets and in heavy light pollution.

Great
It is a very capable filter it functions well for me as a light pollution filter So as far as filters go, there’s a little bit of magic to this one
