Various image plane and coma correctors often provide optimal correction at a sensor distance of 55 mm, meaning that the popular 17.5 mm backfocus ZWO and ToupTek astro cameras require a 37.5 mm extension arm to set the ideal distance. This distance can be achieved using this 21 mm long extension and the 16.5 mm long M48/T2 extension.
