If you place the Moon and planets just next to the sharpest point, a finer focus lens can help. With this focus adapter for a Celestron refractor of 102 mm, you attach a Feather Touch focus lens from Starlight Instruments to your telescope tube.
The adapter comes instead of the original focuser and connects the tube to the new focuser. Celestron has made several models of 102 mm, so be sure to check which one you have. You can find more of this type at our store. Refracting telescopes.
You notice a better focuser immediately, because focusing is smoother and you stop more precisely in the right place. First check the diameter and connection of your tube, or send us the exact type. What you can see with a refractor on a planet, you read in Mars through a telescope.
Against a fogged lens, a rainbow band for 4 inch telescopes, together with a regulator for fog lights.
