In 2008 an amateur telescope maker and astronomer published an ingenious new way to easily focus your DSLR, webcam or CCD camera for taking astrophotos. The method is simple, very intuitive and the device has universally been named after the inventor. The Bahtinov Mask. Farpoint manufactures this *LIFESAVING* astrophotography tool out of virtually indestructable ABS plastic and comes in two major types and in a range of sizes. One mask is a general purpose mask designed to fit refractors and newtonian telescope. The other mask is designed to fit Schmidt Cassegrain telescopes. Both types of mask are available in a range of sizes to cover your needs. ## Features - Bahtinov focus mask for small telescopes - Fits telescopes with dew shield or tube diameter from 2.5" to 4.5" diameter ## Images ![Farpoint FP400 Bahtinov Focus Mask for Telescopes with Dew Shield or Front End Diameter from 2.5" to 4.5" - Image 1](https://m.media-amazon.com/images/I/61-vvyIJptL.jpg) ![Farpoint FP400 Bahtinov Focus Mask for Telescopes with Dew Shield or Front End Diameter from 2.5" to 4.5" - Image 2](https://m.media-amazon.com/images/I/51FDjf-zJML.jpg) ![Farpoint FP400 Bahtinov Focus Mask for Telescopes with Dew Shield or Front End Diameter from 2.5" to 4.5" - Image 3](https://m.media-amazon.com/images/I/61yKPE2K0bL.jpg) ![Farpoint FP400 Bahtinov Focus Mask for Telescopes with Dew Shield or Front End Diameter from 2.5" to 4.5" - Image 4](https://m.media-amazon.com/images/I/61HuPQ-A8gL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ Works but for the Explore Scientific AR102 but needs to be inside the dew shield like picture shows. *by M***T on Reviewed in the United States on July 4, 2017* Well I bought this for the Explore Scientific AR102 doublet be warned this mask will only fit inside of the dew shield on the lens it will not fit on around the dew shield, If you want a mask for the Explore Scientific AR102 might wanna go with the 6.5-inch to 9.5-inch I'm pretty sure that's the right size to fit around the dew shield.Figured I'd save someone a hassle by doing the wrong measuring.However this mask will work however you will need to put this mask inside the dew shield and then have it sit out the outside edge of the front lens. ### ⭐⭐⭐⭐⭐ Quick perfect focus *by C***L on Reviewed in the United States on August 15, 2020* This is the best focusing adaptor, I've ever used. As stated, so simple, over the years of connecting a camera to scope, than to lap top, using some form of software to see, and dialin focus. Wow", so, quick..In all honest, if you have this item attached to front draw tube, on your scope, than on a medium bright star, the time is no more than ten seconds...that's all there is to it...Done! ### ⭐⭐⭐⭐⭐ Easy to use! *by A***N on Reviewed in the United States on May 24, 2020* Just getting into astrophotography. Spending WAY too much time getting focus perfect. I knew these were recommended by many, and for the cost, such an easy thing to justify.WOW! My time for good focus went from 10 minutes (to 1/2 hour!) down to a mere 2 minutes, and with better certainty. Highly recommended!This unit is well made and adustable for fit. --- ## 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.hu/products/440400-farpoint-fp400-bahtinov-focus-mask-for-telescopes-with-dew-shield](https://www.desertcart.hu/products/440400-farpoint-fp400-bahtinov-focus-mask-for-telescopes-with-dew-shield) --- *Product available on Desertcart Hungary* *Store origin: HU* *Last updated: 2026-07-06*
