I'm experimenting with NightCap Camera on my iPhone 7.  Seems pretty versatile, but my skies are garbage so I'm not expecting a lot.

 

Is that the paid or free version?  I have since found out that providing I am actually using it in the dark the iPhone 12 pro will allow speeds up to 30 seconds. Did not see that before as I was going through the settings in daylight.

Yes, I actually often use the native iOS app for this as it also stabilises the image and works really well even hand held.

I recently discovered Nocturne by Unistellar which seems excellent under a dark sky, provided the phone is held steady, ideally tripod mounted. It works out the best exposure and will run for 4 or 5 mins. No idea how it does it but the results were good the first (and only) time I used it. It’s been cloudy ever since!

I have an iPhone 12 (non Pro) and tried a few iPhone apps including…

NightCap - ProCam - SlowShutter - Camera+ 2 - Lightroom - ImageCam - CortexCam - SpiralCam

Both telescope afocal and wide-field on a tripod. Personally everything I’ve tried so far fails to beat the native iOS camera app. Mind, I might well be doing something wrong! However, I can see than one of the above apps might be better on an older iPhone.

The iPhone 12 doesn’t have an astronomy mode. But it does have something called Night Mode which comes on in low light conditions. The allows “exposures” of up to 30 seconds. Although what it actually does is take several shots and stacks - ten 3 sec or nine 3.3 sec shots - depending on what/where you read. 

I’ve heard that the iPhone 13 goes further than this but I’ve no experience of using it.

I had a quick go on Orion with Nocturne last week in my light polluted Bortle 7-8 sky. That’s the first picture. It seems to deal with light pollution well. The second is with my iPhone 12 native camera app using a 30 sec “exposure”. The light pollution is obvious plus (not surprisingly) there’s some star trailing. And I know that when I’ve used the native iOS app in Night Mode in a truly dark sky the background is almost dark. The 3rd picture is the native iOS shot with some quick and dirty editing.
