Im thinking this is for the visual group myself. It’s still a doublet. I’m thinking it’s spend that extra little bit, and get every bit light to come to focus better. It’s giving visual observers some added scopes to decide through, AT102ED, may get a little CA, spend extra, may get as good as the 100ED’s with a wider field and more compact scope for portability. Imaging is still a triplets game, not saying people don’t do it with the doublet as I’ve seen great photos, but this to me is still geared for the visual observer wanting that little extra in the better glass.
I agree with this; I wanted an AT102ED at first, but the correction isn't good enough in my opinion for my purposes so I never went that direction. This new 102EDL however does have good enough correction, it should have no false color on bright planets, unlike the AT102ED which does show CA on them (Venus, Jove....). And being able to get that on an F7 scope changes the mounting significantly from an F9 scope, so to me, that's a huge deal, since someone looking at a 4" frac is likely trying to have it portable and not need a monstrous mount just to handle it. F7 keeps it reasonable still as a grab & go. And it's in the same price category as the SW EvoStar 100 ED at F9, yet shorter and easier mount. Nice to have something else at this price point so there's not just a default single option (especially since the Stellarvue 102mm F7 was discontinued, was same price too). This basically is the Stellarvue 102mm F7 Super with a different brand name. And that's not a bad thing at all.
