At this point something happened, or rather nothing happened. I got sidetracked and didn't do any work on it for over a year, didn't touch it at all..

I had a WO FLT 110 and WO megrez 90 on my mount and sold them to get a fsq 106. That satisfied me for a while but widefield started to get old and I was itching to get in to galaxies and other smaller objects.

This got me motivated to get back in to the build. One thing to note was that a friend of mine bought the same optics as me after hearing about them. He doesn't' have a workshop but did have a friend in china who runs a machine shop. He also doesn't have a paramount so he was going to go for a lightweight carbon fiber tube. He sent me his design and I found that the spider he designed would suit my scope as well. Given the cost to have it done in china it didn't seem sensible to do it myself when I had to buy the material. I got him to do two of them and this arrived a couple months before I resumed the project..

At this pot I had to finish the cell, machine the cell/baffold support and make the baffles. I nice guy, Mike Jones, a professional optician designed the conical baffles for my specific optics.. More pics of this part below.. One is of the form for the primary baffle, a couple of machining the baffold/cell support, the cell triangles unfinished and the collimation bolts. I decided to mill a sphere in the end and glue steel balls. It makes the collimation smoother.
