Non-square pixels, correction software, and accuracy

The Orion Starshoot G3 and G4 cameras uses the Sony ICX829ALA sensors, which has pixels that are 8.3µm × 8.6µm each. According to Google, it uses software to correct for any distortions from using the rectangular pixels. I have used it in the past and I was wondering if the data collected from it is corrupted because of the software used to correct the non-square pixels and should that data be marked as such.

Yes, Orion is no longer around but people are still using the older cameras and that includes me, though I will be using it for spectrometry with a Star Analyzer with my Dob with the technique pioneered by AAVSO member Lauren Herrington.

The Sony ICX829ALA is an interline transfer sensor. Between each pixel is a dead area column, not light sensitive, where the charge is shifted to and read out continuously. Lots of video rate camera sensors use this type sensor.

Probably not a problem combined with the low-resolution grating you’ll be using.

Your system R will cover everything.

The spectrum group may have other comments, so ignore mine, if they say other wise! :smiling_face_with_sunglasses:

I just checked and my Atik490EX CCD cameras use the Sony ICX814 sensor which is an interline readout CCD. Of course, the pixels are square. It is a great camera for photometry and pretty pictures. I have two!
