Here's a picture from the setup at school two nights ago.
Last night I set up the Meade 152ED next to the AP 6" f9 for some side-by-side testing. Using the same type of diagonal on each (AP Maxbright), and transferring the eyepiece back and forth. I mostly used 7mm and 4.8mm Naglers, but also 8mm and 16mm UO Koenigs, and a 55mm Plossl. I let them both cool for about 45 minutes.
Jupiter up first. Nice image in the Meade with the 7mm Nagler. In the AP I immediately realized Io's shadow was transiting, just below a knot that was above the NEB. Back to the Meade, and with better focus it was also visible there. That was the consistent story through the evening. Realized Io was nearing the limb in the AP, found it in the Meade, Noticed some mottling near the S. pole in the AP, then found it in the Meade with careful observation. Saw details in the NEB in the AP, found them again in the Meade.
Pretty much everything I could see in the AP I could find in the Meade, but I always saw it first in the AP. Part of that may have been the Meade taking longer to cool -- the AP is wrapped in Reflectix, and is usable almost as soon as it is opened. But the AP also seemed to have a bit more contrast. Boosting up to a 4.8mm (285X), the views were similar, although holding up a little better in the AP.
On Saturn at 285X, Cassini was a sharply defined line in the AP. In the Meade it would momentarily match the sharpness, but then go a little fuzzy. Titan and Rhea were easy in both. Dione was just visible. Interestingly, however, it was a little bit easier to pick out Tethys in the Meade. The AP has had its front coating removed, and is a triplet, so perhaps the Meade has a hair more throughput (the difference was spotting it around 50% more often in a short time interval).
The moon showed the contrast advantage of the AP. White ridges and crater rims popped out in ways that drew the eye. In the Meade, they were there, but not so eye catching. Again, once I would notice something in the AP, I could find it in the Meade. Same story on the double cluster. Pretty little asterisms would catch my eye in the AP, and then I would find them in the Meade. At 285X the AP had no CA on the moon's limb. The Meade had just a hairline of faint yellow at the very edge - pretty close to APO color correction. Clouds were drifting through, so the only double I had time to observe was Almach, and it was similar in both scopes.
A star test, with the 8mm, on Altair, produced numerous, very fine rings just in and out of focus on the AP. Inside they were purple, but still very sharp. Textbook perfect. Inside of focus on the Meade there were three sharply defined rings with clear gaps between. Outside, there was a fat purple ring around the central point, and then the yellow outer ring. So some under correction. That is probably part of the difference. The Meade was a little harder to get to critical focus (perhaps in part because I'm still getting used to the electric focuser -- I kept wanting to just tweak the knob a little, but the resistance of the motor makes manual fine tuning cumbersome). I kept wishing I had a fine focus knob.
The other contributor to the contrast difference is probably the baffling. I replaced the single baffle of the AP with a system of 6 baffles, painted with Black 2.0. The Meade has 3 baffles that are fairly reflective.
Overall, I'd rate the Meade as offering 90% of the improvement over an Achro that the AP achieves. I didn't encounter anything in the AP that couldn't be found in the Meade with a little extra care. I'll be curious to see if that carries over to deep sky objects, after the moon moves away from full. Optically, it's a very good scope, and I don't think my students will miss anything in viewing through it that they would if I went through the tedious process to pull the AP from its carefully balanced tandem mounting.
Just as I was about to wrap up, the Pleiades appeared in a narrow gap in the trees. So narrow that it was only visible to the Meade. The 55mm framed them nicely, and it was good to see them again, for the first time this season.
