COMO FAZER uma Plataforma Equatorial para Telescópios Dobsonianos

Learn the complete step-by-step guide on how to build a motorized Equatorial Platform for Dobsonian telescopes at home! Discover how to track deep sky objects and planets, accurately compensating for the Earth's rotation for observation and astrophotography. In this video, I show all the materials, tools, and exact measurements (using FreeCAD) to assemble your motorized base. We also compare the use of more affordable Celestron motors with the powerful OnStep system using NEMA 17 motors. If you want to take your Dobsonian to the next level, this is the ultimate DIY guide! 🕒 Video Chapters: 00:00 - Intro: What is an EQ platform and its purpose 01:33 - Materials and tools for assembly 04:10 - Motorization options: Celestron vs. NEMA 17 05:09 - Cutting and manufacturing the latitude arc 07:54 - Building the top board and pin installation 09:07 - Assembling the bottom base, shaft, and bearings 09:50 - Leveling the base with adjustable feet 10:48 - Celestron motor operation and installation 14:07 - Upgrading to the OnStep system with NEMA motor 15:42 - NEMA motor and system installation details 17:04 - Smartphone tracking demonstration 18:37 - How to align the base with true North 19:46 - Latitude calculations and FreeCAD modeling 33:14 - Total project cost and final thoughts 🔗 Links and Contacts Mentioned in the Video: Thiago Rocha Contact (OnStep System / NEMA Motors): wa.me/7781595762 Thiago Rocha's Instagram: @astro_scient Celestron motors, tools, and parts on AliExpress / Mercado Livre: • 2 Iron Screws with Spherical Thread: https://s.click.aliexpress.com/e/_c44... • Zinc Alloy Rhombic Flange Bearing DIY Parts - KP08: https://s.click.aliexpress.com/e/_c4n... • Linear Shaft Rail - D8-150mm: https://s.click.aliexpress.com/e/_c3Y... • Aluminum Flexible Jaw Coupling D19*L25 - 5x8: https://s.click.aliexpress.com/e/_c3y... • Celestron Single Axis Motor Drive: https://s.click.aliexpress.com/e/_c4b... • Universal Mounting Bracket for NEMA 17 Motor: https://s.click.aliexpress.com/e/_c3V... • Timing Pulley Wheel for Belts - 2GT-200-6mm, 16T Bore 5mm, 48T Bore 8mm: https://s.click.aliexpress.com/e/_c3Y... • 8 Pcs Adjustable Leveling Feet: https://meli.la/23LdyXr • 29 X 1.95/2.125 Bicycle Inner Tube: https://meli.la/2GBJ3KL • Bosch Professional Angle Grinder: https://meli.la/2ghvov9 • WAP 12V Cordless Drill: https://meli.la/1p1N45r • 2 Pcs Circular Bubble Level Kit: https://meli.la/1W5oKPf FreeCAD Download: https://www.freecad.org/downloads.php...
