If it measures between 34″ and 42.5″, use the HD Medium. If it measures between 49″ and 56.5″, use the HD Large. Most consumer GEM tripods fall in the HD Medium range; large observatory tripods typically fall in the HD Large range.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use 10″ pneumatic wheels with the HD Large?\u003c\/strong\u003e\u003cbr\u003eYes — the 10″ pneumatic wheel + tow handle upgrade is available separately for all-terrain use.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eOur Recommendation\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe HD Large is the right choice for owners of observatory-class telescope systems with wide-spread tripod legs in the 49″–56.5″ range.

Always measure your tripod at your intended observing height before ordering.\u003c\/p\u003e","brand":"JMI","offers":[{"title":"Default Title","offer_id":53296860201071,"sku":"TPWULGHD","price":838.6,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/TPWULG5.jpg?v=1781714231","url":"https:\/\/ontariotelescope.com\/products\/jmi-heavy-duty-large-universal-wheeley-bar-telescope-dolly","provider":"Ontario Telescope and Accessories","version":"1.0","type":"link"}
