Why shouldn't it work...Televue has been using Emery Cloth in its tubes for years.




You know, I'd heard a rumor that they were doing that. Think I'll be keeping any type of grit far from my optics, thanks anyway!

As far as using flocking to line dew shields, how does one determine that all moisture has evaporated from the absorbent flocking material prior to capping the objective? Sounds iffy to me.

I recently experimented with home made "flocking". 100 grit sandpaper, sprayed with a light coat of matt black paint.

worked very well on the baffle tube of my Mak.

Just a thought for those wanting to maintain the budget theme

I would prefer not to.

Yep, that'll work. When I arrive home from the dark site, I make sure everything I used is uncapped to air out while I'm sleeping. I don't cap things and put them away until I get up six-to-eight hours later.

It seems to help... but I have not tested rigourously. The 3M aluminium oxide paper I used is pretty well bonded together to start with. For the inside of a dewshield, I think this is pretty safe stuff. It also seems to be a rather good light trap

I've also heard of folks grinding up walnut shells and mixing with flat black paint for flocking.

Yes, that's what I did. ScopeStuff and ProtoStar sell it. I just bought some from ScopeStuff.

Has anyone just taken off the dew shield and lightly sanded the glossy plastic and/or flat black painted the inside?

Does someone know what the thread is on the end of the focuser tube? I was thinking of getting a Baader Click Lock if there's one available for those synta threads. Would make it so much easier and precise to rotate the diagonal instead of loosening/tightening 2 screws all the time....
Thanks

oof! I don't think I would do that. Walnut shells are so hard they are used for cleaning firearm cartridges for reloading. if any dust from them got on a lens, and was wiped....

I am not positive, but I do not think Baader clicklock is made with that thread. because of these recent threads about the C-102 scopestuff is backordered on These

If it is a M56 thread, then there is a 2" Clicklock that would work. Keep in mind that the adapter would cost around $100 and for another $50-60 you could replace the entire focuser with the excellent GSO.

Since I had such a good experience with the WO BV in the scope last night, I'm thinking of replacing the focuser with a GSO 10:1. The BV needs a stronger focuser.

It is kind of funny, to load this $60 scope up, with my Leica zoom ($500), dielectric diagonal ($100) and or a binoviewer ($1000)! Everything I stick into the focuser is many times more expensive than the scope itself...but oh, do the accessories ever let the lens loose to perform to its full potential! The jury is still out, but I may use this scope as my first choice grab-n-go scope over the C6!

Thanks for that link. I was a bit surprised by how expensive that is, especially relative to the $59. I already put in vinyl bolts but you really have to crank down on them, especially with a quality 2" diagonal and a glass gernade EP. I guess this accessory would hold better, especially with the brass bolts, but I think I'll hold off for now. But thanks for the link!

Well my experiment was just that.. an experiment because I had no other flocking material. It worked well enough that I'm happy to leave it in place.

of course I understand the concerns about grit particles, but it seems fairly robust to me.

For the extra weight, I have a 2.5lb ankle weights that I just "wrap" around the front of the tube. I then can slide it up and down the tube the counter balance whatever I'm hanging off the back. Like last night I had a binoviewer and two EP's so it got pretty heavy back there.

Wow, you where up over 180x and still looked good? I'm happy with my ES6.7 for 150x in mine.
