Explore Scientific ED102 FCD100 f/7 Carbon Fiber Triplet Refractor w/2.5 inch HEX Focuser (FCD100-10207-CF-01) and more

14 months old--I upgraded to a longer setup! Add a mount and a couple cameras and you're ready to go. For pickup in SF Bay Area, or buyer pays shipping.

The only thing of note is that when I was removing the EAF, I lost one of the focuser set screws. I have replaced it with a bolt that does not interfere with the rotation of the focuser. It should be relatively easy to find a replacement, but if you're swapping it out with an EAF, it will be removed anyway. See photos for how I have secured it right now.

One of the images shows the setup as I was shooting it. Anything not in the below list is not included.
