    How big is too big? Maybe this one is? Doesn't matter trinh hong phuoc will build it :)

    Oh yeah nah no I was laughing at it too, I meant that anybody holding that thing is gonna feel like a god, no worries :) Alaskan, sorry because I know essentially nothing about pumped lasers and anything else really that goes into this project so I’m hoping you can enlighten me. What am I...

    You’ll definitely look like you have super powers too! It’s not often you hear someone say “I’d be unhappy with anything less than 10W”

    That’s some gorgeous machining. I’m excited to see how problems will occur and how they’ll be dealt with, I’ll be following this

    Man this is exciting. I haven’t seen anything previous to this, is the crystal assembly something you put together yourself? Any thoughts on figuring out how to get some batteries to run in parallel inside the tube so that you can extend the runtime without worrying about overvoltage? Or is...

    An electrically pumped surface-emitting semiconductor green laser

    finally! i was wondering when they’d come out with an all-epitaxial, distributed Bragg reflector free, electrically injected surface-emitting green laser.

    [Dual 411nm 1335mW] 2D MAG with PBS cube & Newport mounts.

    bucket of photos certainly destroyed a huge amount of information in all types of forums online when they went for the moneygrab. Thanks for this Alaskan

    Polarizing Filter Mystery!

    I haven't learned exactly how circular polarizers are structured quite yet, but I believe you're correct and we've gotten to the bottom of this. This filter must consist of a rotatable linear polarizer in the front, and behind that a circular polarizer. And these circular polarizers consist of a...

    Polarizing Filter Mystery!

    I remember reading that most modern cameras that use through the lens exposure metering and autofocus use a semi-silvered mirror to divert some of the incoming light for the measurements. If the light is linearly polarized then I guess it doesn't act right when it gets reflected, similar to how...

    Polarizing Filter Mystery!

    Thanks for speculating singlemode. I think i may understand what you're getting at. n5KvNSDXSHE it seems like the angle has little to do with the effect. One thing I forgot to demonstrate in the first video which shows up in this second one is the fact that this effect ONLY happens with...

    Polarizing Filter Mystery!

    oh you're right, I totally forgot about how you just place the string of letters in the youtube brackets, not the whole link. Forgive me. I wonder why it still worked for me and Gazen though? That's a mystery for another day.

    Polarizing Filter Mystery!

    ugh that's frustrating, it must depend on what platform you're viewing on. Here's the direct link. https://youtu.be/WrADyPDVYRg

    Polarizing Filter Mystery!

    Uh oh, that's kinda the most important part. I'll set it to public, maybe that'll fix it

    Polarizing Filter Mystery!

    Hi folks, I've got an unusual phenomena I've discovered involving a polarizing filter for photography. I thought a video would do a much better job of explaining the question than text would, so I made a quick video. So obviously this filter can't be JUST two polarizing filters, but what do...

    Post your random pics!

    Hey that's perfect! Untracked widefield photography is what I started in. Take several exposures as long exposures, limited to about 15 seconds to avoid star trails. You can stack your exposures to further increase detail and reduce noise, you can get some pretty awesome images that way. And...
