I'd rather have extra than have devices unusably bright. Thanks.

Hope that is enough. I'll soon find out...when I get it. I tried to warn you... I think I even tried two sheets of the AstroGizmo, and there was still some of the nonred bleed through. Not dim enough. Not the best tint for visual astronomy. Did the vendor even test it? Like I said, it might be OK for AP, but what do APers care about dark adaptation? Not much, IME. Yep, I just now double-checked with two layers of AstroGizmo on my Android tablet. Nonred colors still come through. This stuff is not only not dark enough, it's not even the correct tint for visual astronomy.

If you can dim your devices enough through their settings, you might be able to get by with one layer. What I like about using a layer of Rubylinth with a layer of the AstroGizmo, is that the AstroGizmo clings better to the Android screen. So I had cut a somewhat smaller sheet of the Rubylinth to fit under the AstroGizmo. The clingy, outer edge of the AstroGizmo helps keep the Rubylinth from sliding off the tablet during dewy conditions. And, even though the AstroGizmo is not the correct tint, it dims the Rubylinth to a better level of brightness. Without the Rubylinth, the AstroGizmo is just wrong. But since that setup, I've added better detention with Velcro straps to keep the layers secure to the tablet. I've also noticed that sometimes the smaller piece of Rubylinth will slip a little and expose an AstroGizmo-only strip of the tablet. Too bright! So I think I'll cut a bigger piece of the Rubylinth to fit under the AstroGizmo. I also have a clear film that I might put on the tablet's screen first. Then maybe I can use a couple sheets of Rubylinth secure with Velcro and the clear clingy film. But IME without a doubt the AstroGizmo is the wrong tint and is not dim enough! Hey, I'm not an expert on this stuff, but through my own experience in the field (literally) at a dark site, I know what works and what doesn't work.

I also have several pieces of the Tap Plastics red transparencies, but it might be too thick for the touch screen to work. On the other hand, how about the Meridian stuff? Same as AstroGizmos?

But judging from photos of it in use at the company's website posted elsewhere on this thread, it seems to be very similar in tint and translucence to the AstroGizmo material. In other words, the wrong color and too bright. Not too good. But if you can set your tablet so that ONLY red and black show through on all apps and buttons, and set the brightness way down, then a couple layers of AstroGizmo might be good enough. I don't think it will be good enough. But give it a try. I can't adjust my Android tablet that way. Some white will still appear at the on-screen border buttons and nonred in other apps. So I absolutely need a GOOD filter like Rubylinth that will not show any colors anywhere other than red and black.

I've ordered a 12x15" piece...well was supposed to be 12x15...I ended up getting a tiny bit smaller than 12" wide. I depended on that full 12" width, so I can slice it in between to get two 6.00" pieces. I was short by 1/4", which makes it very very close to not covering the width of my iPad. Got only 1mm to spare...which is not really enough. Anyhow, I'm hoping to use three pieces...in the meantime, I'm going to use a small piece of tape to cover either the left or right edge to minimize light leak due to the shortness. It seems that three pieces with the iPad dimmed all the way down might do the trick...I'll try it at night when I get a chance.

But if any other-than-red-and-black colors are coming from the tablet, I'm afraid they will bleed through the AstroGizmo screens. I think it's more a matter of wrong tint rather than wrong brightness level.

And I agree with you two pieces is not enough...just that my 12x15" piece is large enough for three pieces. I'll still be on the lookout for better and darker material.

The order was placed on last Friday, and it arrived in Wednesdays mail. The sheets are somewhat oversized, so you will most likely want to trim them down. Given the small margin on an iPhone between the illuminated screen and the edges of the phone, trim carefully. Having failed Arts & Crafts as a grade schooler I was still a little wide on the initial cut. The overhang is annoying in use. The film does indeed cling easily (and securely) to a clean screen. It removes easily with no residue or film. Time will tell how durable it is. Touch sensitivity feels the same. Since I bought two sheets, I tried doubling them. The product does cling to itself, so this is a viable strategy. The touch sensitivity is still good thru two layers. In terms of darkness, this will of course be subjective. I left my iPhone on Automatic setting for brightness (probably a mistake in terms of power usage). I found the light levels to acceptable. In fact, it was dimmer than my normal red LED headlamp and my red LightWedge I use on paper charts. (If you have a Light Wedge, you know it is actually quite bright. Normally I leave it off and just use my red headlamp for chart reading.) I suspect that anyone who finds their normal red lights acceptable will find a single layer of red cling acceptable.

Guess I will have to try the Meridian product.

I have the Asus Transformer tablet. With the tablet dimmed all the way down, and SkySafari Pro set to night vision (or not), one sheet of Rubylinth is still too bright to use at my dark site. I need a sheet of Rubylinth and one of AstroGizmo. Mike Post Extras:       Pages: 1 | 2 | (show all)
