    Default 10" F5.1 Dob Flocking.



    I have a Dark Star Dobsonian which I rather like and I have recently decided to flock the tube. The inside pre-flocking was a sort of dull dark grey-ish paint. I have used 45cm width flocking paper and applied it the roundy way to the mirror and focuser ends of the tube, not along its length. I currently have a gap of about 45 cm in the center of the tube that is not flocked, part of the reason for this that there are a number of nuts there that hold the tube to the bearing box assembly that I would have to cut around. Is it worth doing anything about the bare patch? How much light actually arrives there I guess is the root question?
    Any ideas/expertise out there?
    Thanks

    If you really want to, use the flocking to cover the nuts also. Takes them out of the equation for reflections.
    Never, under any circumstances, take a sleeping pill and laxative on the same night.

    You can also use a flat black paint or marker to blacken the nuts in case you ever need to remove them again.

    Thanks both of you, I have patched the bare bits with some odds and ends of flocking paper I had left over from a previous project. Will attack the nuts with a black felt tip marker next.
    Regards

    Another thing you can do is to make a glare shield that prevents stray light from entering the bottom of the focuser.
    You can see the one that Bladekeeper has made for his dobsonian here: https://www.dropbox.com/s/aqtg76jpq4..._0066.jpg?dl=0
    Contact him for information on what materials he used and how to attach it

    Thanks, I'll try that I have some spare light shield material from an SCT I used to own!
