I'm selling my Triplet Carbon Fiber APO 90mm f/6.6. Unfortunately they don't sell this scope at Teleskop Express anymore but they do sell the cell by itself. I found the link here. The closest existing model would be this one, same specs but no CF tube.

I've used this scope a fair bit and loved it. See photo gallery. I originally bought it because it's a triplet with a FPL-53 glass and it has a very good color correction so it can be used with a DSLR or OSC camera.

I shot the moon saturn transit here and also the TLE here so you can see how sharp it is.

Here's a photo of the rig in situ loaded with all my stuff.

So it comes with the tube, 10:1 micro focuser and a clam shell. I also added a dedicated field flattener/corrector for this scope valued at $250. Comes with its own padded hard case so I can ship anywhere.

Asking $1,100.00 + shipping at buyer's expenses. Or pick up in Sydney if you're local. I can drop the scope within a couple of hours of Sydney. Let me know.

PS: tried to take a couple of shots of the front cell. Quite hard really as it's pretty thick, about 100mm, and some of the lenses appear almost invisible so I shone a bright torch down the tube to pick up reflections and a bit of dust in the process.

[SOLD NOW] - thanks for all the interest.

How does the focuser hold up, Marc? Looks like you've got a fair bit of weight on it there. Any image shift when locking?

Been thinking about something in the 600-700mm range, and while I was looking for a 100mm, this could do the trick. Assuming I can get it past the wife (will be a struggle, I've been on a spree lately!).

The focuser is alright if you just have the camera but as you see in the picture I had the AO, OAG, Baader FFC and the camera. That was an extreme case and a fair bit of overhang so I had to brace all the tubes. When I used it with the camera only I never had any issues. It's quite smooth. Also has a rotator built-in so it comes handy to re-frame.
