Don't get me wrong, the product is fine, but it would be nice if the photograph and the description of the product were EXACTLY the same as the product that arrived. If there are problems, just send an email and let ME decide, not Amazon, probably there is some law somewhere about trade descriptions, Amazon would do well to read it and not just expect customers to send the item back; waste of time and money for everyone. ### ⭐⭐⭐ 3.0 out of 5 stars No cleaning cloth. *by M***E on Reviewed in the United Kingdom on 3 July 2015* Nice eyepiece except there was no cleaning cloth supplied like the description says. ### ⭐⭐⭐⭐ 4.0 out of 5 stars very useful *by P***E on Reviewed in the United Kingdom on 1 October 2013* It was just what i needed , right price for this eyepiece.Works perfectly with eyepiece projection in astrophotographyNice!! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/54096555-ostara-telescope-plossl-high-resolution-40mm-eyepiece-fully-coated-wide](https://www.desertcart.tn/products/54096555-ostara-telescope-plossl-high-resolution-40mm-eyepiece-fully-coated-wide) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-21*
