to flock, or not to flock??

Recommended Posts

I have seen quite a lot of people on here stating that their telescope is "fully flocked"

Could someone take the time and explain what this means please, as i have not seen it referenced anywhere else but here!!

thanks in advance:iamwithstupid:

Hiya,

The reason for doing it is to reduce the internal reflections in the optical tube which in turn helps boost contrast of the observed image giving a darker background.

Most people flock newtonian type telescopes but a few also flock Refractors as well. Me included

I purchased my flocking material from FLO as I could not source it from a hobby shop...

Hi Spacemonkey.

Flocking is usually done to newtonian reflectors, but other sacopes may benefit.

The (not so) black paint inside the tubes reflects stray light onto both primary and secondary mirrors. this gives background glow and so poor contrast. Especially if you are having to deal with a lot of light pollution.

You can demonstrate this by shining a low power red torch into the tube side away from the 'glassware'. If the view through the eyepiece turns red, you have a case for flocking.

Flocking is usually done by applying a sticky back (or gluing) matt black layer to the inside of the tube. Near the top of a newt is the imprtant part.

Hope this helps. David.

I'm thinking of doing this. Though i don't have much light pollution, one thing that struck me when moving from the frac to my 200p was the "background glow".

I want to do it, but can't help but think it'l be an absolute nightmare to get the stuff in there, straight, stuck correctly etc etc... Just how manageable is it? or is it worth going for the non sticky "spring into place" stuff?

A 200p should be a cinch :D

Try doing a 4 inch tube, now that's trickier :clouds1:

Hi,

Sorry to hijack the post but would you flock a brand new scope? Im presuming that the answer would be yes but how does that affect warranty?

I found doing my 10" Refector sort of easy, remove every thing,cut the flock to length to go round the tube, peel back a 1" or so line it up with the tube them rub in as you go round, 2 and a bit lengths and then put it all back together, i marked the mirror holder with a bit of tape so the same holes were lined up then collimate all done...

I'd agree with Tinker. I just flocked my 8" reflector, it was no trouble at all. It hardly needs collimating either as you've not really adjusted anything, just remember to measure your spiderveins before you take out the secondary, it just makes things easier when putting it back together.
