Here’s a Cheshire collimator image of my lens cell in a WO 71GT Triplet. It looks like my cell is not collimated but is that actually what this shows. I’d appreciate the forums experience on this.
Of course the lens cell on this scope cannot be collimated as it screws into the front of the tube with no adjustment available other than shimming or machining the end of the scope tube to be square with its axis. The individual lenses can be adjusted of course for alignment to each other as the second image shows.
I don't recommend using a Cheshire collimator on a refractor like this. If its even the slightest bit not square to the optics, you will make a mess of things. I don't think its accurate enough, and I have never known anyone to align the elements of a refractor with this type of collimator. It works well to align the mirrors of a reflector, but you are talking about an enormous distance between those surfaces, versus the incredibly small distance between lens elements.
The lens cell CAN be collimated, and the sets of screws is exactly how its done. In any refractor, you only want to adjust alignment of the elements to each other. You would never want to shim or machine anything in the scope on your own.
WO has a 2 year warranty, so I recommend trying it out and actually taking photos with it, or doing a high magnification star test before touching anything. If you find it to be off, get a replacement scope or lens cell. It unscrews off, as you know.
