USED 1.25" Sirius Optics Filters

The MV1 filter really cuts down that harsh violet halo on bright stars, making deep-sky views noticeably sharper through my scope. Considering it's used, the glass looked spotless and threaded onto my eyepiece perfectly smooth.

I was a little nervous buying used filters, but the MV1 arrived in really clean shape with no scratches I could see. It noticeably deepened the contrast on Jupiter’s bands through my 8-inch dob without washing out the finer details.

The MV1 filter cleaned up the blue halos on Jupiter noticeably better than the cheaper filter I was using before. For a used piece of glass, the threads are smooth and it came without a scratch.
