Hi all, A nice fellow asked for a design for a wedge for his SCT, so while I was at it, I thought I would go the whole hog and add it to the DIY page on the A.S.I.G.N. Observatory website. http://www.asignobservatory.com/DIY.aspx Its a start, a good guide and open for as many modifications as your skills and imagination will allow. I hope it comes in handy for those looking to move onto astrophotography. This is a simple and rigid wedge, that will get the job done. Cheers, Baz.
