I recently purchased a Lumicon 2” Oiii filter from CN classifieds for $155. They were listed as used in very good condition, and the seller did disclose that there were some dust particles. Upon receiving them, and being a bit of a perfectionist, I was a bit disappointed at how many dust particles there were. I of course attempted to remove them using my air blaster rocket squeeze bulb, but to no avail.
Should I be worried about them impacting the view? The coatings themselves look flawless. If so, is there a safe way to remove them? Or should I request a refund?
