If you want to mount a Feather Touch or other focuser from Starlight Instruments on an Astro-Physics telescope, the adapter must fit exactly on the thread of the tube. This adapter for Astro-Physics with 4.875 inch x 24 TPI threaded thread is made for tubes with exactly that thread.<\/p>\n\n\n\n

TPI stands for the number of wires per inch. The adapter connects the tube of your Astro-Physics with a focuser from Starlight Instruments. You can find other connections in our focus adapter and intermediate rings<\/a>.<\/p>\n\n\n\n

Before ordering, check which wire your tube has. If in doubt, measure the outer diameter of the wire and check the documentation of your telescope. A different focal length can change the distance to the focal point, which is especially important if you are using a camera and a flatener. You can read more about photography here. photographing stars<\/a>.<\/p>\n\n\n\n

For Astro-Physics telescopes with a 2.75 inch connection there is a adapter from 2.75 to 2 inch<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"
