مستعمل - مرشح Burgess Optical Planetary CN540 1.25 بوصة

The threads are clean and the glass has no obvious scratches I could see under a bright light. For a used filter, the contrast it gives on Jupiter is really noticeable compared to my standard one. Definitely a solid find for the price.

I was a little nervous buying used gear, but this filter’s glass is spotless and the threads feel smooth. It paired perfectly with my 1.25" eyepieces for lunar viewing.

The threads are clean and the filter screws into my eyepiece smoothly, which surprised me for a used piece. It’s cutting down the moon’s glare nicely in my 8-inch scope, and I can see a bit more surface detail now.
