I did consider making it into a folded design but the necessary mirrors would increase the weight. Collimation is harder but that wasn't the stopper, in the end I decided the additional weight and plain butt ugly nature of most folded designs convinced me to stay with my light-weight truss open tube design (ala the iStar TCR). I have looked at folded designs now and then since but no one has produced one I'd want to own. If I was building it again, I would go with a carbon fibre truss tube design like my imaging newt, it would weigh even less and be great to look at.

Do you have a pic of your scope, I would love to see how it developed
