I liked seeing the concept again, although the impact was lessened for me since I remember that STAR rebus puzzle so vividly. The perils of having a long memory! I bet most solvers won't have seen it, and will thus have a much bigger a-ha moment.
The BIG DIPPER is part of URSA MAJOR, the GREAT BEAR? Wha ... ? Huh. Apparently, it is! How is it that I never knew this? (Probably because I spent most of my childhood watching "Gilligan's Island." Fun fact, Mr. Howell's teddy bear was named Teddy.)
Jeff packs in a ton of thematic material, the NORTH STAR rounding things out. Now that one felt much more solid than URSA MAJOR. Yes, the BIG DIPPER seems to be a part of the GREAT BEAR, but that's more an incidental curiosity. I learned to find the NORTH STAR using the BIG DIPPER as a guide, linking them forever in my head.
I think I would have been happier with just BIG DIPPER and NORTH STAR, plus the visual. That would have also allowed for smoother fill, along with a more accurate representation of the BIG DIPPER. It looks kind of … skewed. Like it got shoved into a 15x15 box.
It may not seem so difficult to drop in seven extra letters to form the visual, but it's actually a (great) bear. So much flexibility taken away from that middle section, when you have to work around fixed letters! And if you shift a letter even one square, the visual starts to look all wonky. Not a surprise to get a bunch of odd entries in RONDEL, ORBIS, SERE, and a potentially lethal crossing in ESO BESO / ARABY. Oof.
A good concept even the second time around, and I understand the desire to toss in URSA MAJOR / GREAT BEAR to help bulk out the theme. It's a tough call — without them, some solvers might have considered the puzzle thin.
