Alex, the flocked material used in your telescope must have been poorly made cheap material. I have two Televue refractors, both have the Televue installed original flocked fabric lining the tubes. The Pronto is 25 years old, the NP101 is 20 years old, with no issues whatsoever in either telescope. Mark
Well I flocked my C14 in 2007 with spotlight adhesive felt for flocking. It's still in place and never once shed any lint. The scope resides outside under a Telegizmo cover all year round. Sorry to hear of someone else having this issue.
Thank you Alex for your warning.
I have been thinking about flocking my eight inch rather than my old method of baffling paint and sawdust.
I have had a look at my six inch that I baffled and did the sawdust trick a decade ago and it shows no signs of failure.
Thanks again.

I’m beginning to think a fair solution is to start with a sheet of stiff rag paper as used by artists - the kind with a rough surface and ideally in black - and paint this with Black 2.0 (from Stuart’ Semple’s website) and fit that neatly into the OTA.
This way it could be inserted into an OTA without the need to remove the optics and everything else bolted to the OTa (as with paint).
This way it can be easily removed or replaced later, if need be.
I think baffles are the go and I plan to use them to resist flex.
I may use resin and saw dudt as a base and that with sawdust should add strength one could think.
But hsving hsd the eight for a year and yet to do any adjustment I cant se doing it for a while...its on a very long to do list☺

I managed a few pictures of the fiber coated optics. Flaming EVERYWHERE these fibers, corrector plate, primary, secondary, and they will be all over the rear of the primary, inside and outside of the baffle tube, and it will affect contrast . Photos show the really dirty corrector (most of the dust is one the inside) and the fibers on the primary - tricky photo to take that of the primary's surface.
Alex.
Looking at these pics it does look very bad indeed. This fabric sheds a lot for some reason. I guess it was flocked with the wrong type of material. I've never seen such a mess before. Even a door mat is cleaner than this. It shouldn't deter anyone from flocking their scope with good quality material that is opaque across the spectrum. You get what you pay for.
That’s only on American Taks where they have no clue how to adjust them or feel they must put a FT on them “just because”
. Photos show the really dirty corrector (most of the dust is one the inside) and the fibers on the primary - tricky photo to take that of the primary's surface.
