    Default Tube Flocking - Protostar tube liner or Flockboard sheets?



    If I were to flock the tube of my 8" dob, what would be the better way to go: The Protostar tube liner or the Flockboard sheets? The sheets look fairly easy to install and you could air space it with thin pieces of foam tape. The tube liner is supposed to be sized for popular commercial tubes and looks fairly easy but one install review I read on this site Protostar Air-Space Tube Liner Install seems to have it be not as smooth as it looks to be.

    So if I were to flock my dob tube, which way would be the better one to go with?

    I think either way you go, it will help out a lot. No matter which material you use, its always possible to run into problems. Working inside of a tube is tight, so its best to plan it out and work slowly. I also used the ScopeStuff sheets in the Z10. With the peel and stick type, I found it easier to do in small sections with small overlaps. I also did not do the whole tube, but most of it. I didn't want to take the altitude bearings off, so I just did in from both ends up to the bearings and left that little bit in the middle unflocked. Afterall, the most important parts are around the focuser area and around the mirror. It is indeed dark in there. If you happen to wind up with any air bubbles, just use a utility knife to make a slit in the bubble and smooth it out. I had some left over so I did the inside of the dew shield on the AR127 as well. The mirror box on the big dob is painted black inside, so I think I will likely use the same flocking paper to do that one as well.

    I have used protostar and its works great. The key is to get it installed without wrinkles and i found it to be tough, im sure with practice it gets easier. Once you get it installed and stuck down good. Take a sharp knife and cut slits up and down the length of the flocking. You wont see the slits and it helps its from trying to pull up and come unstuck.

    Am getting ready today to install the 0.03" thick Protostar flock board. Was looking at the installation instruction they sent which states to let the flock board over lap. Am not sure I like this, thinking about cutting so as to have it fit line to line, Just don't like the idea of overlapping 0.03" flock board. Also think will install double sided tape at the seam only. The scope am flocking is a Orion pro8. Will let you no how it turns out.

    What is the problem with overlapping? Its not that thick (less than 1mm) and won't encroach into the light path. Irregardless, good luck and hope it turns out well.

    I think flocking the whole tube is a waste. I would take a different tact.
    : Flock the first, say, 10 inches of the tube opposite the focuser.
    : Flock any surface on the primary mirror cell that would radiate incoming light back toward the secondary mirror. In my experience, this is the worst source of reflected light on the GSO dobs.

    Any other remaining reflections are small potatoes compared to these two.

    To illustrate the second point, take a flash photo down your OTA. Note which surfaces are brightest, with emphasis on the ones that are parallel to the mirror surface. (Here's what my 10" GSO dob looked like before I fixed it. The cell frame is second only to the mirror in brightness. That kills detail and contrast, guaranteed.).
