Is anybody else having trouble using data from iTelescope?
When I do a simple stack, I'm finding that the 'calibrated' data is highly overcorrected by their flats. Dust motes, huge black band on one edge and such.
When I downloaded the raw data & cal masters, they seem to be a mess as well. Some are flipped up/down and some aren't. After I sorted that out... I did full calibration and then stacked, the results were worse than before.
I have no clue what to do.
Anybody else having these problems?
I don't know the state of the calibration files at this moment, but I do know they had problems with proper calibration frames in the past. You can email them and ask for an explanation and usually they refund that session. That at least was my experience a year or so ago. This is something that should become way better with the incorporation of APP over there, but will still depend on how they take the calibration frames.
When viewing the masters, they seem "OK" (not great, because that black band I mentioned is not the same in the flats, as in my raw data.) At least the dust motes are there, and when I re-do the orientation, they're in the correct place. It's just overdone in the final output.
Is there a way to control how much the flats are correcting?
Not really, if the flats are taken as they should, APP will use them correctly. If it over-corrects, I think it would mean that the light fall-off in the flats is more severe then they are in the lights for some reason.
