Joe, When your iPhone camera app is open look in the upper left corner of the screen. You'll see the little lightning bolt icon - that's the flash control. Tap it and you'll be given a choice between on, off and auto. One thing I really like about my phone's camera is the "HDR" option. This is for High Dynamic Range, and it stacks two images of different exposures and blends them for improved saturation. It's especially helpful in situations where there is a combination of bright light and shadows. Using HDR forces the flash off. It's my favorite setting. There are a variety of great apps available for the iPhone that enhance the utility of the camera - try googling some of them and you'll see what I'm talking about. I like using "Camera Genius," "Afterlight," "iMotion" and "360." The concept of astrophotography with a smartphone is intriguing.

What I was trying to do is see if I could stack a bunch of frames. I'll try it again if I can figure out how to turn off the flash! ------------------------------ On Tue, Dec 2, 2014 9:06 AM MST Chuck Hards wrote:

Seth, I have a Galaxy S5, and the camera is pretty spiffy. 16MP resolution and lots of interesting features. I've been experimenting with it for solar and lunar shots. I'm getting more and more impressed with the capabilities of smartphone cameras.

Here is a lunar shot taken about a month ago, afocally through a 50mm f/12 refractor, using the smartphone:

And here is a shot of the recent partial solar eclipse, same phone but a 50mm f/9 refractor & Baader solar filter material:

I have the Orion universal smartphone bracket to hold it up to the eyepiece. Takes some fiddling but worth it once adjusted. There are also cable releases available for most smartphones, that plug into the headphone jack. Check eBay or Amazon for your particular model.

Joe, have you tried using your iPhone but not using the flash? Now you've got me wanting to experiment with mine.
