I had my TSA120 for a 6 night astronomy trip last week. It was the first multi-night observing session that I've had with the telescope. Two things became immediately apparent: (1) The optics are stunningly good and (2) most of my eyepieces did not come to focus,natively, with the FeatherTouch focuser. I needed more out focus. In other words the focuser needed to be racked all the way out and the eyepiece pulled out a little for it to focus. I was not using any of the Takahashi extension tubes that came with the telescope.
I configured the focuser with A-P end cap and then threaded on the A-P 3 knob compression ring adapter.
I can change this out to the Takahashi endcap and then thread in the included TAK extension tube and 2" eyepiece adpater for the diagonal that came with the scope. But this uses a set screw to clamp the diagonal. I want compression ring or click lock.
Help me reconfigure the back-end plumbing so it will come to focus. I will thread the TAK extension tube on. But what can I thread onto the TAK extension tube to give me compression fittings? Does TAK make a compression fitted eyepiece/diagonal holder?
Below is a photo of the scope as I configured it on my trip.
Thanks in advance.
