I had the chance to have a quick look at an ATC today. No chance to get a feeling for the quality of the optics, the weather was just too horrible with driving rain.
However, a couple of observations: The tripod foot is a joke. It's too small. No matter what the ludicrous Swarovski marketing says, you really need a tripod (or at least a monopod) for the ATC, and a more substantial tripod foot would have been much better. If I were to use an ATC on a tripod and carry the scope on the tripod, I'd tether the scope to the tripod.
I also think the scope is too heavy for a "lightweight" scope. Let's face it, most people will use it as a lightweight alternative to their bigger scopes, and IMO it would have been better to keep the weight down more, for instance by using a physically smaller, lighter eyepiece. The eyepiece they used is almost a thick in diameter as the objective lens. Talk about a mismatch.
BTW, anyone here who can do a serious review including star testing and a comparison to some scopes of known quality?

I've had the good fortune to use an ATC 56 for a few weeks now, and my observations are a little different. I use it it on the Gitzo GT1545T Traveller - the plate it comes with is fairly small. When scanning on a flat railing or wall, without the tripod, I've been pleasantly surprised at how rock steady it is, scanning at 17x is great, and going up to 25x for scanning has been fine. It's not something I plan to do regularly, but as the scope is in my camera bag anyway, I can if required. It's a great combination with the Gitzo, it's the same weight as my camera and lens I carry over my shoulder all day long.
It's certainly heavier and chunkier than the other <60mm alternatives but to put it bluntly, they are not want you want to be using to use on a regular basis due to the quality of the eyepiece - I was directly comparing it with the Kowa this morning, which has such a tiny, narrow eyepiece that's pretty uncomfortable for long scans - and this is where I see the biggest difference, this might well be aimed at the travelling birder, whereas the ATC for me is designed for everyday use. The ATC eyepiece however is big, wide and chunky, like a big boys scope, no big difference to using the 65 or 85 (I've had both for many years), it's a very comfortable mismatch with the objective. It doesn't feel like you're using a tiny scope when scanning, and scanning through shorebirds for an hour is no discomfort - scanning at x17 is also much more pleasant than x25, as a starting point. At x40 I found it razor sharp, and though ATX65/85 are excellent at x60, I so very, very rarely went beyond x40 anyway.
I thought it would be a scope I would use for travelling or hiking. However, during these weeks I've come to realise it's absolutely adequate for my everyday birding - though I don't go to gull roosts nor do long-distance seawatching, or anything as unsavoury as that anymore!
Quality vs size/weight comparison will mean I am most likely to use the ATC 56 the vast majority of the time now - it'll be interesting to see if I do decide to use my ATX65 on any particular occasion actually as the more I think about it, the more I doubt I will.
