Has anyone come up with a red screen solution for tablets out in the field? Even on my dimmest setting,  my tablets excel sheet is still way too bright, I haven't seen any apps which put a red screen over everything on every window opened.

 

How are people preserving their night vision when using tablets or smart phone? When I used my laptop, i just put a screen over my laptop since its not a touch screen but a tablet has a few more challenges.

A hobby or craft shop and a sheet of thin red acrylic sheet. Can get them in various densities of red.

Cut to size BUT you will lose the touch screen feature.

 

Skysafari has a red option, and I hate it. shocked.gifshocked.gif

Cannot get used to it, have problems focusing and I also like to see the star colors - with the night setting everything is red, even the blue ones. Also the background is black and the rest is not exactly bright. Suppose some have the milky way showing and maybe bright.

 

At this rate people will complain about the moon being bright and not being red. lol.giflol.gif

That's what i use. On my tablets. I use an Android app called ScreenDim full to adjust the brightness and contrast.

 

Non-amoled pixels leak light so the red film is a necessity.

 

My phone has an Amoled screen but other apps can flash me so I'll still use a red film.

I love SkySafari's red/night screen.  I use it all the time.

I found "Night Screen Filter" in the playstore for android. It seems to put a red filter over everything on the screen in any window. The red intensity is adjustable and its easy to turn on and off.

Works pretty good on my Galaxy S9. I'll try it on my Samsung tablet.

If you are using iOS (iPad) there is a system-wide setting to apply a coloured filter:
- Settings > Accessibility > Display & Text Size > Colour Filters >...

There’s also a shortcut to apply/disable the filters by triple-clicking the home button.

It’s useful because it prevents being blinded if you accidentally quote SkySafari.

Ralph:

 

Your S9 has an AMOLED screen so you don't have the light leakage problem.  Some Samsung tablets have AMOLED screens, some don't..

 

Hopefully yours does..  otherwise you'll want a red film filter.

THE best option, in my opinion, for reddening a mobile device screen is the Xtra Dark Red Eyes Cling from Sirius Astro Products It's a red cling filter that blocks out all blue/white light. It comes in 2 sizes that are intended for you to trim to fit your device. I've had one for both my phone and table for 5 yrs now and love it. If you use it with skysafari the best option is to run the app in monochrome mode or the red telrad circles wont be visible. It's dark enough that you'll need to turn your screen brightness up to see it in the field.
 Scroll to the bottom of the products page and make sure to select the XtraDark version the regular version will still let blue light bleed through.

Do you use the Xtra dark screen or the standard screen? Dark screens always seem too day. I always end up getting too dark a screen so I may order the standard screen for my tablet.

I didn't relize the was posted already as message #2 out there.

Thanks to both who noted this.

I use the Xtra Dark Cling screen. I want the tablet to be barely readable when my eyes are dark adapted.

I use Rubylith. It used to be used in print shops back in the day when they used process cameras for shooting large negatives. Not used anymore. You can get sheets of it on Ebay. Works real well. I taped mine on a piece of clear lexan the size of my laptop screen. I just use a rubber band to keep it on.

I set up my iPad and iPhone to toggle to red mode by pushing the home button three times quickly.  You can Google instructions on how to set it up.  Not sure if Droids have that capability.  Brightness is controlled via the regular brightness slider.

I also have been using the Sirius Astro Xtra Dark Red Eyes Cling for a pair of iPads. Works great. I also use leather cases with flip over covers and put loop velcro on the back of the iPad case so I can stick it to hook velcro at the mount. I keep them synced to the Nexus DSC computers connected to the mounts.

 

I sometimes use the night vision mode on my iPad Pro when not observing at a star party. It works fine but the Sirius Astro stuff is more reliably dark when at a star party.

I have the red plastic screen covering. I forget what it is called.  Found a post, it is called Rubylith. https://www.cloudyni...-mobile-screen/

You cut it to fit your display.

I don't use it. I hunt Nebula for Imaging. And most of it is red.

Red screen hides it.

So I simply adjust my display as dark as is practical for my eyes and run with it.

Nobody in my yard but me and sometimes my little dog. But he isn't interest in Astronomy.

 

So when you get your red screen covering, you may not like it.

Get the Xtra Dark. You can always turn up your screen brightness to get the screen image what you want it to be., The standard will still let Blue light and other colors bleed through which in turn will effect your dark adaption.

I use a monochrome theme with the red cling to prevent this problem.

What a timely discussion. 

I just got my XT 10i running on tablet control. 

I use Velcro to attach the tablet to the OTA - a bit below the eye piece. 

Yes, I found I was making my own light pollution with the tablet.    

 

I like the colors of the sky safari screen, and highlighted observing lists.   I didn't like the monotone night mode. 

I could not see my highlighted objects.  

 

So what I do now is turn the brightness all the way down, and I purchased a piece of red acrylic from Amazon.

I had to cut to size (score and snap).   I then glued little hinges (glue was 'goop') to the screen and tablet.  

 

So while guiding the scope - red screen is up -

once an object is located,  I can immediately flip the red screen down - which instantly cuts all the white light

Its not perfect, but it helps tremendously - and you retain touch control with a quick flip of the screen.

In iOS devices, you can use the built-in accessibility settings to produce the dimmest, reddest screen possible in under a minute, absolutely free.

The process is identical on iPads and iPhones and is just as effective on both!

 

Follow these easy steps:

 

Settings > Accessibility > Accessibility Shortcut >

Enable Color Filters, Enable Reduce White Point.

 

Settings > Accessibility > Display & Text Size > Color Filters >

Enable, Set Intensity to maximum setting, Set Hue to minimum setting.

Triple-click Home button, disable Color Filters.

 

Settings > Accessibility > Display & Text Size > Reduce White Point >

Enable, Set slider to maximum setting.

Triple-click Home button, disable Reduce White Point.

 

Now, you can triple-click the Home button to instantly apply one or both settings.  Reduce White Point is very strong when used in conjunction with the brightness slider; with both set to minimum, it can be difficult to read the screen even in complete darkness.  I always set Reduce White Point before I go to bed, it makes your phone much easier on the eyes in the middle of the night and first thing in the morning.

 

Don't waste money on third-party solutions or tape red saran wrap to your screen if you have an iOS device!

I've placed an order last week and its gone completely dead. No notifications and no shipment information.
Its probably not wise to buy from this place any more.
