I installed the new focuser on my 130GTX and added the QUAD with the QSIwsg adapter.

I noticed to bring it to focus, the draw tube is nearly in with only about 10mm to spare.

Is this by design or just the way the lens worked out?

I reach focus easily but was wondering why the focus was nearly completely in. Just curious. I should have enough room to run a V-curve which runs it in further…..
