It is a little on the heavy side (14 lb/6.4 kg vs 12 lb/5.4 kg for the SCT) but it's not too much for a senior citizen like me to handle. It has a nice long dew shield that extends and retracts smoothly. I use the manual focuser with a Bahtinov mask as a focus aid. It dials in smoothly and maintains focus once set. With the 1.0x field flattener, the stars are sharp and round points of light all across the field of view. In comparison with the 8" SCT with a 0.63x focal reducer, the quality of the images has improved greatly. In comparison with the SV550 80 mm telescope, it has over twice the light-gathering capability, so I am able to get more detail in my images during a single night of photography. The only down-side is that it is pretty long, but that is to be expected with a refractor with a wide aperture. With the dew-shield extended and my camera attached, it is 43 inches (109 cm) long, which means that I have to be much more careful as the telescope approaches the meridian. However I have safety features set up to avoid collision with the tripod legs so it isn't a deal breaker. All in all, I am extremely happy with this telescope and expect to get many years of great images with it.

The scope has a solid build quality and excellent, smooth, focuser. I added the ZWO EAF 5V with ease without the need to make modifications. The handle is a must, and makes it easier to carry. It's got some weight to it 5KG (~12lbs) with a finder scope and accessories. But still easy to transport.I learned that to remove the course focuser knob you have to remove a small screw that will let you see the screws on the base of the knob when you rotate it, this was my biggest holdup.

It is a rather large 122mm aperture ApoChromat (see definition on Wikipedia) with excellent color correction. On a few good nights I was able to get a few images with it, just to test it out. I used a Skywatcher HEQ5 mount (an AVX would work just as well) and a RisingCam IMX571 camera. Pros : Excellent optical quality for the price Very well-made focuser, ring mounts and 0.8x reducer Complete accessories (finder mount, guider mount etc) Cons : This thing has a good size and is not light !

The build quality is superb, the optics are bright and sharp, the focus mechanism is extremely solid and smooth. The entire assembly is much more solid that it appears to be in pictures. Definitely a high end scope. Pretty thrilled with it so far. After getting some more clear nights boy this thing performs beyond expectations, I’m imaging with the ASI2600MM pro in mono with it and wow, pinpoint stars across the entire feild, no aberration noticeable at all. This scope is the deal of the century. I mounted it to a Losmandy rail to add room for power supplies and my imaging computer. I still haven’t had enough clear night to really push it to it’s limits but having taken some images under less than perfect conditions the results are impressive to say the least…

I have been using this telescope for several weeks now, and its quality has completely astounded me. Its high-quality optics provide crystal clear views of the night sky that I had never experienced before owning this instrument. The setup process was straightforward and user-friendly which makes my stargazing sessions so much more enjoyable.

Great quality, dual speed focuser, no chromatic aberration. Good job! If you want to use 100 of your pictures get the flattener. That will be my next purchase.

This triplet APO refractor gives me crisp stars. Good DSO images. The only complaint is that the dovetail plate needs to be longer to achieve balance with a DSLR.
