Electroluminescent light panel or app on mobile phone / tablet for taking flats?

[dazzystar]

Hi All,

I've been advised to take flats which is fine. Do I need an EL panel or is there an app I can use on an iPad which basically turns the screen white and would that be sufficient? I know other people using a white T-shirt and point the OTA to the sky for their flats.

Cheers

I use a panel but you could try this https://www.whitescreen.org/

Thanks Peter.

I used a tablet screen before switching to this: https://www.amazon.co.uk/gp/product/B08K4MVK1B/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&th=1

On the tablet I simply painted a pure white image, set the screen brightness to match my desktop monitor (about 110 cd/m^2), disabled sleep timer and used the Ekos auto flats exposure (only for the 1st shot, then manually set the exposure to match it for the rest).

I have the same light pad as you do but thought that as LEDs basically flicker that this is not an ideal light source. Could be wrong though!
