This is a perfect application for the \u003cstrong\u003eSide by side Losmandy plate 350mm PLUS\u003c\/strong\u003e. You can mount your imaging refractor on one saddle and your guide scope on the other. This creates a very stable platform that minimizes differential flexure, leading to tighter stars in your final image of M31 compared to piggybacking the guide scope.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat makes the PLUS system construction of this plate better than others?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eUnlike plates that may be cast or bent, every component of the PLUS system is \u003cstrong\u003eCNC-machined from a solid block of aluminum\u003c\/strong\u003e. This process results in superior mechanical rigidity and precise tolerances. The system is then hard-anodized for durability, ensuring a flex-free and reliable connection for your valuable astronomy equipment.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eDo I need to worry about the total weight with the Side by side Losmandy plate 350mm PLUS?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes. While the plate itself is designed to be rigid, you must always consider the total payload. You need to sum the weight of both telescopes, all accessories (cameras, guide scopes, etc.), and the side-by-side plate itself. Ensure this total weight is well within the specified payload capacity of your equatorial mount for optimal tracking and guiding.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ctable class=\"DAV-specifications\"\u003e\n\u003ctbody\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cul class=\"DAV-grid\"\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/davidastro.com\/pages\/primalucelab-warranty-policy\" rel=\"noopener\" target=\"_blank\"\u003ePrimaLuceLab 1-Year Warranty\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PrimaLuceLab","offers":[{"title":"Default Title","offer_id":52913403560221,"sku":"PLLPDLOS350P","price":315.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/5280\/1565\/files\/PrimaLuceLab-Side-by-side-Losmandy-plate-350mm-PLUS-1_bc0cff0b-cdc9-4107-861e-32ec186c48e7.jpg?v=1789090438"}],"url":"https:\/\/davidastro.com\/en-us\/collections\/primalucelab-plus-dovetail-plates-clamps-and-rings.oembed?page=3","provider":"David Astro","version":"1.0","type":"link"}
