Painting Inside Of Telescope Tube. Pain the inside of the tube with some kind of glue, dump in quarts of sawdust, tamp sawdust into glue, let dry, and shake out excess sawdust. Then paint with the flattest black spray you can access. The sawdust created millions upon millions of. 1 Answer. Telescopes have the inner part of the tube blackened to minimize scattered light reaching the eyepiece. Such scattered light reduces contrast, and hence reduces the ability to see very faint objects, or low contrast detail. A.
Painting the inside of a telescope tube is a simple process that can help improve your viewing experience. Here are some tips for getting the job done right.
Before you start painting, you’ll want to clean the inside of the telescope tube to remove any dust or dirt. This can be done by using a soft, lint-free cloth and a mild detergent. Be sure to rinse off the cloth afterwards to avoid leaving any residue inside the tube.
Once the tube is clean and dry, it’s time to begin painting. Make sure to use a paint that is specifically designed for use on telescopes. This type of paint is usually available at most hobby stores. Apply the paint in thin, even coats, and allow each coat to dry completely before applying the next.
When painting, it’s important to start from the top of the tube and work your way down. This will help ensure that the paint is evenly distributed and that no spots are left unpainted. Also, be sure to use long, smooth strokes when applying the paint. This will help to avoid any drips or runs.
Finally, after the paint has dried, you may want to give the telescope tube a final coat of clear sealant. This will help to protect the paint and keep it looking good for a longer period of time. Again, make sure to use a sealant that is specifically designed for use on telescopes.
Painting the inside of a telescope tube is a great way to improve your viewing experience. With the right supplies and a bit of patience, you can have your telescope looking like new in no time!
Flocking a Newtonian Telescope
Very few videos or tutorials around on Flocking (reducing the internal reflections of the tube by fitting black non-reflecting material). Here is my (successful) attempt, but with the first faltering steps left in, as I learn't more from the mistakes than getting it right first time! My longest video, at just over 18 mins!
The real acid test is to remove the mirror an put the tube at a shallow angle to the sun and see how bright the tube wall looks. I've yet to find a flat black paint that doesn't look shiny at shallow angles under these conditions. Perhaps if there was one. Repainting in an original color is harder than you may think. There are just about a zillion shades of white out there, and matching white is further complicated by how white ages over time. The white on your telescope tube today may not be the white it. Hold tube at like a 45 degree angle, have bottom of tube pointing into a big plastic basin. Then get your paint and pour into the tube from the top, all while you are rotating the tube around as the paint flows to the bottom of the inside of the tube., Painting Inside Of Telescope Tube.
