Unfortunately no access to the internal SD card (storage capacity 12GB on eVscope 1 and 64GB on eQuinox & eVscope 2) – you upload data to the Unistellar network via Wi-Fi. I think the market is for people who either don’t have the time or technical expertise (let’s face it Astrophotography has a steep learning-curve) and to improve the accessibility of Astronomy & Astrophotography to a wider audience. The on-board computer stacks and processes the frames (dark and background removal, shift-adding and stacking) to produce an improved image in real time. Personally there are times I’d like to get down ‘n’ dirty with the RAW data being an ex-Systems Analyst & data monkey.

I’m by no means an expert but opening an image in Affinity Photo 2 showed the following info for an example PNG from my eVscope:
2560 x 1920px, 4.92MP, RGBA/8 – sRGB IEC61966-2.1
Apple dev state RGBA8 as a 32-bit-per-pixel, fixed point pixel format in which the red, green and blue colour components precede the alpha value.
However, the Sony IMX224LQR image sensor in my eVscope 1 is 12-bit (improved Sony IMX347 on eVscope 2).

Thanks for making me look into this subject a bit further… everyday’s a learning day for me. Plus, it nudged me into sending a reminder to Unistellar about their promises around open-access to the RAW data.
