So reading the second linked to article they 'think' that babies are aware of an inverted view for a short time. I wonder if this could be proved with the new surgery they are starting to use to give adults who haven't had sight their vision back for the first time. They could articulate what they can see couldn't they? It might help prove the upside down theory.

So it's still cloudy so I am doing some reading of all this useful free information on this great site. I thought I'd start at the top so my apologies if these questions are ones I'll encounter the answers to as I work my way through the rest of the information. I had two questions at I read the OP's PDF. 1. How do I determine what magnitude of star I am looking at? I presume 'magnitude' means how bright the star is. So how do you work this out - the guide refers to selecting stars at magnitude 4 or 3, but how do you measure/determine this - is there some way of 'metering' these? 2. Several times in the guide it refers to knowing the distance in degrees across things such as viewfinders and lenses. I can see how a lens could represent a distance in degrees, but how do I know what our lenses will show? We have the ones in my signature and I think my son has just received a 32mm plossl as a present - is there a way of working this out?

I like the idea of an accessory case. I have some bits of foam left from making a yoga mat dew guard. I think i could easily fill a small case wuth a few layers of it and cut into the foam as required.

These dew shields seem quite important. Not wanting to get my brand new telescope damper than it will get anyway I've already got my camping mat on order and the 'scope is not even delivered yet!! LOL I thought I might experiment with sticky Velcro for joining it together in areas where I might one day want to remove it and double sided tape in other areas.
