 +===== Also is it possible to disable iOS app automatic updates? =====
 +
 +Yes. Go to iPhone or iPad Settings > App Store. Turn App Updates on or off.
 +
 +===== Is it possible to pause a mosaic and refocus to account for temp change? =====
 +
 +Yes. When you restart the capture, the Seestar will give you options to start over or continue the capture. (You can't pause a mosaic session and resume it several hours later because, of course, the sky will have moved a bunch.(Actually, Earth will have moved, but you know what I mean.) You can, however, start an entire new mosaic later or even days/weeks/years later because the stuff up there doesn't move much with respect to each other.

-It seems the Seestar was designed for a tablet. Some of the menus are hidden off the screen on a phone, and the "joystick" is smack in the middle covering what you're trying to center. On an tablet you can see the full menu and the joystick is offset.+It seems the Seestar was designed for a tablet. Originally, some of the menus were hidden off the screen on a phone, and the "joystick" was smack in the middle covering what you're trying to center. On a tablet you could see the full menu and the joystick was offset. Now all that has been fixed and they both work well, although the iPad, of course, will give you a much bigger picture. ((If you want a really big picture use the Screen Mirroring feature on the iPhone and Screen Casgt on Android devices.))

 Seestar stacks subs to increase the signal to noise ratio (SNR). When the scope combines two subs the signal is doubled but the noise increases only 1.4 times. Put 100 subs together you've improved the SNR 10x. Seestar stacks subs to increase the signal to noise ratio (SNR).

-What's the big deal with SNR? A single frame will look very noisy, like a mobile phone photograph taken at night. But if you increase the SNR the noise begins to disappear and that allows you to boost the brightness of the images (it's called 'stretching the histogram.')+What's the big deal with SNR?

 The Seestar will automatically stack frames as long as you let it run. When you stop the process it will save a single image, the result of the stacking process, to your mobile devices picture app. If you have "save subs' turned on in Settings you'll find each image that was added to the stack in My Works.  The Seestar will automatically stack frames as long as you let it run.

-Until ZWO relaxes the rejection algorithm((In a recently rare few minutes of clear skies before the marine layer clouds rolled in, I collected only 22 minutes of photons in 49 minutes on the clock! Thin, invisible clouds were probably the culprits.)), and they give the choice to save rejected sub frames, 5 seconds is my preference. +Until ZWO relaxes the rejection algorithm((In a recently rare few minutes of clear skies before the marine layer clouds rolled in, I collected only 22 minutes of photons in 49 minutes on the clock!
