After reading up on the Coulter on Cloudynights.com and on Kirk Mona's excellent Coulter Odyssey web page (http://www.silverbugstudio.com/kirk/coulter/index.html), I decided to upgrade the primary mirror cell and focuser first.
The cell came from JStar which is a one-person operation based in California. The cell is fairly heavy duty, but very easy to adjust and to install.
All of the photos of the cell and spider are here:
After the installation of the cell, the scope looks like this:
Because of the dramatic reduction in the weight of the scope's cell, the balance was changed so I needed to add a couple of hand weights to the scope to rebalance it.
The new cell dramatically improves the cool down times of the scope. I can start observing less then half an hour after taking the scope outside. Whereas before, I would have to wait 2 hours or so before observing.
All of the photos of the scope with cell are here:
