Thanks for the replies everyone,
For this trip I have brought my viewfinder along to gauge what a small aperture is capable of if that is all you have. I was glad I did as I got quite a few Messier objects around Sagittarius last night. The cross hairs got in the way but something was definitely better than nothing. I suppose I haven't seriously taken notice of how much I can see through it. Being a finder I usually only briefly look through it before going to the main scope. A forgotten hero in some ways. The experience only confirms that I could definitely use a smaller aperture aid not only for travelling but also if I just want to pop outside without setting up my 10".
The binocs from Andrews at this point in time seem like the best deal if they are as good as you recommend Mental. I don't have a camera so that kind of rules that out Zero. I have been looking at the Orion mini giants but at twice the price not sure now.
I'm interested in the fact that the binocs are equal to a single aperture of greater size. It was what I was hoping for that because there are two apertures than it would be plausible that twice the light could be gathered. Am I right in thinking this?
