By mounting between the focuser base and the focuser body, this component physically elevates the entire assembly, effectively shifting the available focus range outward.

Rack your focuser all the way out and insert the accessory that won't reach focus. Then, slowly pull the accessory out of the drawtube until the image is sharp. The length of the gap between the accessory's shoulder and the focuser is the approximate riser height you need.

Binoviewers typically require significant in-focus travel, but on some Newtonian designs, the problem is insufficient out-travel. If you cannot achieve focus with your current setup, a riser will move the entire focuser outward, giving you the range needed to bring the binoviewer to a sharp focus, often without needing a Barlow or optical corrector assembly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eMy camera needs 55mm of back focus, but my 2.0\" Feather Touch focuser is racked out on my imaging Newtonian.

The goal is to select a riser that places your camera's ideal focus point near the middle of the focuser's drawtube travel for fine adjustments.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWill the Starlight Instruments 2.0\" Riser introduce any flex into my imaging train?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eNo. The Starlight Instruments 2.0\" Riser is machined from a solid piece of aluminum to the same high tolerances as Feather Touch focusers.
