… that the kit was popular. That’s some achievement.
I’ll have a look at Ken’s design if it’s still available. I’m quite optimistic that a Littrow (such as Lhires) could be made but it would take me a year and some investment. (Probably easier to take those parts to a specialist and get them made). It’s down to cost/benefit I suppose. Could it be done cheaper and more accurately than a Lhires? In all likelihood, “no”. Personal satisfaction apart.
Many thanks for your response, very informative.
