[QUOTE="dipped, post: 3442754, member: 9471"] I had a chance to try the Gavia out in my local reserve shop today, priced at £1595. First impressions, good build quality but maybe easily scuffed rubber armoring. Smooth even focusing clockwise to infinity. There appears to be no case supplied in the box, maybe it's coming. I tried it out on the internal artificial star in the shop, I'll do my best to describe what I saw. Outside focus pretty good circular rings well defined, maybe slightly thicker at ten o'clock but only slightly. Purple flare to outer edge of "star". Inside focus the inner rings were missing replaced by a white disc and were not so well defined, so spherical aberration not as well corrected as some scopes I've tested. Don't know what the disc indicates but the rings were still pretty round so good collimation. The artificial star was not resolved as well as some scopes I've tested and I got the impression there was a bit of CA there too. The scope had a bit of vignetting at the very close focus end. I checked this a few times as I wasn't sure if there was any at all but I'm pretty sure it's there I'm guessing there is a way of knowing for sure by shining a light inside the objective lens end? I couldn't manage to take any pictures of the star images. In the reserve shop the Gavia is pitched against the Swarovski 65HD with 25-50 zoom or for £400 more you can buy a cased Kowa 88 with 25-60 zoom. I know what I would do if I was in a position to spend that sort of money (on a new scope). [/QUOTE]
