I am selling a set of ANTLIA astronomical imaging filters. These are all filters suitable for monochrome imaging. ・V-pro LRGB filter φ36mm Since I have kept these filters set in a filter wheel since I purchased them, they are in beautiful condition with no scratches or clouding. As these are products for astronomy enthusiasts, I will omit individual product descriptions. I am selling these because I plan to switch to 2-inch size filters.
