    Hi Pat,

    I know this is an old post. But I was wondering how the shroud worked out for you? Did you make one?

    My dobson has also three truss poles, just like yours. I would like to make or buy a Light shrouds. But I'm hesitant as the shroud might cut some light.

     

    Yes still does the job and does it well if your worried you can make,metal hoops the same ones that are in wedding dresses but to be honnest it does not cut to much light 

    I have tested it on dimmer galaxies shroud on and no shroud it made little to no change to brightness or contrast

    keep looking up

  2. Hi well back from town they had three grades of nylon Lycra  how to describe them grade 1 rubbish,grade  2 not so rubbish but thicker a bit heavy ,grade three with a £6 pound per metre  price supper heavy and easy to sew ( famous last words ) so,here's my plan note pic below 

    A/B are as you guess top and bottom of scope 

    the three verticals lines are the truss tubes 

    parts ,1,2,3 camping matts cut down to each size, I,found 10" of,camping Matt does not un-balance the scope 

    my plan is to glue Velcro to part s 1 and 3 along the dotted lines on pic 

    I will have a 2" band  with no Velcro.   ( subject to trail and error this may turn in to 3 or 4 pieces) 

    with the black Lycra will sew Velcro top and bottom lenght of this 29" 

    This may not work out but I have nothing to loose I will not cut the Lycra to size I will most prob lightly sew it on for test purpose as if the 2" camp matt does not keep it from of the truss tubes and interfere with the light path

    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. 

    That sounds good to me a wonder if ribs that are used in wedding  dress's could be used you see some with loops in ?

  4. 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 ?

  5. Orion Mini Giant 9x63's... Unusual exit pupil,but I really like these binoculars. They gather a heap of light and have a lovely sharp and contrasty view.

    Canon 18x50 Image Stabilised... Now these binoculars I freaking LOVE!!! The view is spectacular, the 18x mag resolves so many more stars in the sky than the 9x's and the image stabilisation works an absolute treat!! I've (only just) resolved Saturns rings hand held with these (true, I promise) and last night got my first glimpse of Jupiter and all four Galilean moons plus a couple cloud bands (ok, now I'm lying, I couldn't really see the cloud bands!). Never feel the need to mount them... And at that magnification, this says a lot for how well the IS works!

    Really
