A quick flocking question

[starship trooper]

hi there,

I brought some of this fab foam from hobby craft HobbyCraft Fab Foam 45cm by 30cm Sheets - HobbyCraft Arts and Crafts Supplies Online Shop to make a dew shield for my sw 200pds and was wondering if it would be ok to use to flock the ota?

Do pds need flocking?

I have also been reading this write up about flocking http://www.urania.be/forum/download.php?f=1&file=baffling.pdf and it was saying about the main areas to flock and one was around the primary cell to stop stray light enter around the sides of the cell so i was wondering if i cut a big circle to go behind the cell would that be ok and not hamper the cells cooling?

Also because the fab foam isnt already got adhesive on it what could i use to stick it to the ota ?

All help appreciated cheers dazz:icon_scratch:

Anybody have any thoughts

How thick is this stuff?. The protostar flocking paper is very thin and has negligible effect on the inside diameter of the OTA. It is also very matt black. Any sheen on the foam will possibly cause more problems than it solves.

its about 2mm thick and is quite matt black i think i am going to do so test with it i think.

What other materals do people use?

Cheers

This is what I used for my Dob: Fablon - Black Velour

Well I have made a dew shield (unwanted light blocker) out of it and gave it and shall see how that works I also cut some to fit behind the primary mirror which has cut the light to 0 the enters from around the side o the mirror.

No, its too shiny. Use black velour fablon.
