If you are purchasing a $150 eyepiece for a telescope, you shouldn't just do your research here on Amazon. This is basically a big store filled with everything, kind of like cyber Walmart. Just because they carry something it doesn't mean that they have experts listing it. You should do your research on virtually ANY other website which all list EXACTLY how the modularity works on these eyepieces. This message also goes to Joe who gave this eyepiece a 1-star review because he was too lazy and too hasty to actually read how these eyepieces work. I am not trying to scold anyone here but please research technical things from appropriate sources. Last but not least this eyepiece is amazing and the modularity is something to behold. these is FOV los and some aberration when attaching different rings, but overall it is an incredibly effective way of increasing your eyepiece variety without spending money on extra eyepieces. **Q: How exactly does this connect to a dslr when using it with a dobsonian?** A: yes --- ## 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.fi/products/55283425-baader-hyperion-5mm-eyepiece](https://www.desertcart.fi/products/55283425-baader-hyperion-5mm-eyepiece) --- *Product available on Desertcart Finland* *Store origin: FI* *Last updated: 2026-05-16*
