I bought this to use with my C102hd ota to help with the CA. I have barely used it, as I will sell the C102ota (I've sold it's mount) so don't really need it. I've used it on my xt4.5, it will bring out some detail in planets, Jupiter's bands for example. Has maybe a few dust specs and a very slight smudge (small) on the inside coat which doesn't affect the views-you need a magnifying glass to see it. Coatings are in very good condition, not scratched. I have the original plastic foam lined case it comes in, $50 includes shipping USPS in cont.us only.
Email any questions, Paypal add $2 or postal money order okay, thanks for looking.
