Until the calibration data is made available, which I assume will be shortly, here is some preliminary data from job 2201 of ic1396 , the Elephant Trunk nebula which we are all familiar with.
The subs were all 180s exposures, with 5 each in RGB and 20,30,40 respectively in Ha, O3 and S2. As noted below only 30 of the S2 were used.
Caution
These images have come from uncalibrated data, the only calibration being, Cosmetic Correction and Background Extraction. Only a quick glance of the data was carried out and as a result 10 from the S2 data were excluded, these appeared to me to be slightly out of focus. Also all the included images are in JPEG format, a 'lossy' format.
Early analysis leads me to conclude that the Ha filter appears to be the weakest in terms of aberrations, you may however arrive at a different conclusion. To assist you are some images. Refer back to the cautionary notes above.
Included are 5x5 panel mosaics from Aberration Inspector using a panel size of 1024 pixels, which you should be able to zoom into at 100%. Included are close ups of the Garnet star, Mu Cephei, taken in Ha, O3 and S2, as this star was not part of the mosaics. The RGB images of that star appeared fine and are not included.
Owing to the amount of data there needs to be a second post, which will follow shortly.
The following images are sequenced in Ha, O3 and S2 order. The Aberration Inspector mosaics followed by close ups of Mu Cephei.
