I bought this flocking material to flock with my Askar400 refractor which had a serious off-axis reflection issue. The material was very easy to work with and stayed put inside the internal wall without issue. From the test shots along the way, I noticed it greatly increase the contrast of the image with a fix exposure values. A lot of background "glow" was eliminated from the after images which came across as skyglow/light pollution. I tried a bit of backing material from a local craft store and it was not as dark, thin, and shed a lot of lint.
This material also sheds a bit of lint(very short and fine ones), but I use some painter tapes to dap on the surfaces to pull out the loose bits. I give it 4 stars only because I do not have experience with another flocking material besides the one from the craft store.

After flocking my SW 90mm MAK I've noticed great improvement in contrast. Handling is a bit tricky so I stuck onto acetate sheets, cut to size, job done.
Beware though thorough cleaning required before used inside a telescope as it sheds tiny fluff so I ended up dismantling my MAK and cleaning it.
Might get away with some sticky tape to remove the excess fluff but lint roller seem to work best. Overall recommended.

Excellent product and service

Very good product,i shall buy again.Excellent service from FLO as always!

Good quality flocking, but worth shaking or gently brushing off 'black dust' and using adhesive tape to lift off any light coloured particles before fitting to telescope.

I thought I may get away with using cheaper self adhesive felt from a craft shop but it was slightly shiney, this flocking is excellent easy to cut and easy to apply.

Used this to flock a Celestron 6SE. I had issues with oil contamination leeching out from the main mirror tube assembly so had to strip down to put right. This flock has provided an impressive deep black to the inside of the tube - zero shine. I found it straightforward to apply with good adhesion - remember to add a little extra in case it runs off when applying and trim with a scalpel / craft knife. An advantage is that the screw ends are now covered up - small extra gain there.

Excellent service as always.

Preparation and accuracy are required for long telescope tubes for example 14" F/5. Pre flocking, size up the width of the roll against the tube length then cut required amount of sections. Prior to the doing the job revers roll the flock material and fit elastic bands to hold the reversed rolled flock leave for a few hours this will keep the material in a convenient shape for covering the inside of the tube. It is wise to draw a centre line inside the tube before starting the work. Use this datum line to square up the rolled up section of the flock. Adhesion is very good the release paper is slight nuisance, use a friend to help and shout at. A big difference is noticed.

A1 service and product from FLO as usual
I bought this to line the inside of a dew shield for Edge HD800 - easy to fit and sticks well - I know it will cut down reflections as it is definitely matt black
