I've departed from my usual post to one that mimics what I remember seeing at the eyepiece:

How did I do?

Very nice! This is close to what I see in my Quark. I've yet to succeed in capturing anything like this with my phone. Prominences go well, but surface details are a major challenge.

 

 

Clear skies!

Thank you! I had a lot of fun when I was single stacked, and I think in some ways, ss is better for my one-man-gong operation with a phone – the ultimate prom chaser.

Wow ! That's pretty close to what one sees on the eyepiece of an H-Alpha scope.

I looked again today and decided my memory was poor! The eyepiece image appears brighter and more glowing to my eye:

Thanks to all for the encouragement. Clear skies! 

 

More good seeing today, and I'm still recording.

This is incredible! How did you shoot these with your iPhone? Nightcap? Something similar?

Thank you. Of the phones I've tried, iPhone 13 and 14 ProMax's 3x camera works best. The 2x camera of 11 and 12 also works well. I use an app that gives manual control of the camera and allows time lapse (ProCam 8) 

 

The specs on Android cameras seem great, but often only the built-in camera app can access the telephoto camera, and those apps can be found wanting for astrophotographers. If any of you find a way to make your phone work afocally, please share.

Do you mind sharing exposure details? I use nightcap for cell phone NV photography that allows ISO, exposure and shutter times, etc.

I really enjoy cell camera photography for 2 reasons- it minimally interferes with visual observing and the pictures stay true to what you see in the eyepiece.

I've forgotten - are those snapshots or images processed by recording a video?

Here's a photo of the screen from 22 Feb. At capture, with the color temperature set to 10k, I look for a slightly amber solar disc as a sign of proper exposure. It's not until post processing that the disk becomes reddish. I wish there were a special app that could apply my default corrections to the live image, but as it is, a yellow disk affords a lot of contrast.

My images are single frames – no stacking or sharpening.

OK, this is going to sound like a stupid question, but which of the 3 lenses on the iPhone 13/14 Pro Max is the 3X telephoto camera? Since I have to put it into a holder with a mask that will only reveal one of them I need to know where to place the hole. And if I use the native camera app, or Camera+ or ProCamera it seems it's different:

 

Native app - lower left lens

Camera+ app - lower left lens

ProCamera app - upper left lens

The 3x camera is the one nearest the corner.

Thanks Eric. Yes, that is the one that the ProCamera app wants to use. waytogo.gif
