Iridium flares and ISOs

[Star-Lord]

Hi all,

I've noticed that in about an hour an Iridium Flare will be flying by.

I'm using a Huawei P9 smartphone on a mount. I can do up to a maximum of 30s exposures, just wondering about the ISO.

Whenever I've done night time shots in town of statues/building/skyline etc I leave the ISO low 100/200 at most and that still gets in stars, when I take shots of just stars (nothing in the foreground) I ramp up the ISO to 3200 for 20/30s exposure.

For an iridium flare what would be the best ISO range for that?

thanks

SL

Cool! North south, east or west?

(I mean the flare.)
