The GT102 is a 102 mm refractor for visual viewing and astrophotography. You can find similar telescopes at our store. Single refractor tubes<\/a>. A 3 inch focus ring allows for larger camera sensors and heavier accessories.<\/p>\n\n\n\n Before ordering, check that the connection of your tube matches this adapter. If you are using a Flattening for your refractor<\/a>, Then make sure that the distance to the camera is correct again after the conversion.<\/p>\n\n\n\n For accurate focusing on stars, a Bahtinov mask for 4 inch William Optics<\/a> useful. If you want to motorize the focus later, check the Wireless MicroTouch motor focus<\/a> for 3 inch Feather Touch focusers.<\/p>","protected":false},"excerpt":{"rendered":" With this you can mount a 3
