<p>After repeated trial shooting, stars sometimes blur at 60 sec exposure with auto guide. 30 sec or less, stars are stable and appear as dots. Consistently good results are obtained with live stacking of 30 seconds or less.

This increases the power and thus the accuracy.</strong></p><p>And an adapter has been added to allow the electric drill to rotate drive at high speed for break in.</p><p><strong>UPDATED: 27 SEP 2022</strong><br>The OnStep circuit will be changed to Wemos&CNC3. The material is easily obtained and easy to assemble. The back cover will be modified accordingly.<br> </p><p>DEC_Housing_Back1_PCBSupport.stl >>> DEC_CircuitHolder.stl<br>DEC_Housing_Back2.stl >>> DEC_CircuitCover.stl<br>DEC_Housing_Back3.stl >>> DEC_MotorCover.stl<br><br>↓↓↓↓↓↓↓↓<br><a href="https://mr-deep-addicted.com/?p=1873">How to assemble OnStep Wemos&CNC3</a><br><br>Uploaded DEC_Arca_Arigata_Plate.stl</p><p><strong>UPDATED: 15 SEP 2022</strong><br>Uploaded 1 file that I had forgotten to upload. <i>DEC_Housing_Back1_PCBSupport</i></p><p><strong>UPDATED: 24 JUN 2022</strong><br>Updated assemble instruction for 3D printed parts<br>↓↓↓↓↓↓↓↓<br><a href="https://mr-deep-addicted.com/?page_id=1300">https://mr-deep-addicted.com/?page_id=1300</a></p><p><br>Full 3D Printed Equatorial Mount.<br>RA: 1:180 DEC: 1:45<br>With Microsteps 1/16 RA: 1:1600 DEC: 1:400</p><p>The heart of this equatorial mount is the cycloid drive.</p><p>Click here for an instruction...<br><a href="https://mr-deep-addicted.com/?page_id=1300">https://mr-deep-addicted.com/?page_id=1300</a></p><p>The above site is written in Japanese, but has a translation function.</p>
