This is a Coulter 13.1 inch mirror from the 1980’s in the days of the blue tubes. It’s a good mirror as Coulters go and makes a nice, inexpensive light bucket. It comes with a spider for a 15 inch tube and a 2 ½ inch secondary which is smaller than the original and optimized for a low-profile focuser. The smaller secondary delivers a substantial performance boost. The coatings are very good for the age since it has lived in the dry Colorado climate all its life. There are a number of tiny specks, flaws and blemishes but they are all very small and will not detract from the performance in any serious way. It does not need recoating at this time. US sale only. Paypal only and I handle the fee. Buyer pays shipping.
