Light shrouds for trusstube dob

[todd8137]

Hi  a little advice needed here ,I see all these great shrouds on big dobs 16",18" ect  are these custom made ? Or of the shelf  I did try and use my home made ones  I used camping matts , and some flocking material ,I also tried to make one from black material .not have in a sowing machine sowing by  hand was a pain ,but the camp Matt ones unbalance my scope ,what I want to know Is if I use a tight fitting one made from material spandex does it cut the light out as it will pull tight against the three truss poles ? Will this cut the apature down ?

Hi Pat

Have you a picture of the scope itself? tough to know what will impede on the light path without seeing it TBH.

I know some people have added rigid loops to shrouds to help keep them out of the light path.

Pat, the shroud which came with my Sumerian was from 'Shrouds by Heather'

http://www.scopeshrouds.com

Very nicely made, it shields stray light effectively and did not cut any light out in the light path. I'll try and find a picture looking down towards the mirror with it fitted.

Ahh, looking at your truss design I see why you think it would be a problem. I agree that I think a material shroud would cut into the light path on your scope because it only has three truss pairs, not four like the Sumerian. As Steve says, some form of rigid hoops would be needed...

Got mine from shrouds by Heather as well, very pleased with it.

Thanks all so it a conundrum I will e mail the  said company in the states and send pics and see what' they think ,if this is a non starter ,what else would any one suggest ,when the scopes in the obsy  i do not need any shrouds ect.Its  when people come round to view with me am worried they will drop some thing or when I travel to dark sites I would like one

I see what you mean (nice scope BTW)

How about making some rings up out of plastic or lightweight wood that run around the trusses. So they make a kind of tube for the material to run around? Any semi rigid lightweight material should do the trick. 

You cold even sew them into some kind of pockets so they became part of the shroud.

You can but the material of eBay.  its a nylon lycra blend. its stretches tight so no need for ribs or anything.

Dan, Pat's truss design only uses 3 pairs, not 4 like yours, so he will have problems unless he uses some form of hoops to keep the material out of the light path.

I think he has it over the lower part of the UTA like mine it will be fine.

my mate did mine ok. you must have been using the wrong needles

[estwing]

you really,really struggle with spandex...lycra might be easier...

[estwing]

rip-stop is also a great fabric to use and very easy to sew...
