Many Thanks,
Christine,Leif and Andy for your replies.
I have looked at WWS and there are many other things of interest,which I will look into, but as for bean bags you must be able to make them much cheaper than that.
For Christine ,
you say you use a bean bag to stabilize you digiscoping rig, why?
For Andy Bright,
I see from your site
www.digiscoped.com (that's a plug for you! not that you need one) that you have a small bean bag ontop of your 500/600 lens, are you using this instead of, or as well as your hand to dampen/stabilize the lens?
Not to sure about vermiculite as I believe it is used by gardeners to "store" moisture and is also used in hydroponics?
