If you have a hefty camera with a filter wheel attached to your Ritchey-Chr\u00e9tien, you want the focus ring to be securely and straightly attached to the rear. With this Feather Touch RC adapter, you can attach a 3-inch Feather Touch focus ring to the rear of an RC.<\/p>\n\n\n\n

An RC is widely used for astrophotography. The connection at the back varies per brand and size, so check that this adapter matches the thread or flange of your telescope. You can find an overview of the available adapters here. Ritchey-Chr\u00e9tien telescopes<\/a>.<\/p>\n\n\n\n

Take into account the rear focus, because a different focus with an adapter can change the distance to the focal point, and with an RC, that distance is very important. After the conversion, also check the collimation, for example with a artificial star for the star test<\/a>.<\/p>\n\n\n\n

If you want to focus with a motor on a 3 inch Feather Touch, then look at the wired MicroTouch for 3 inch<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"
