I might take a look at doing this when the 505 arrives, I will have a 532 that I can compare them to as well!

It looks similar, the difference is slight, but noticable (I think). I actually gave in and ordered the 505nm one yesterday so I've got that coming as well. 😄 Sadly I don't own this laser anymore so I'll never know, haha.

Our light sensitivity changes though, the 555nm is the peak for photopic vision (daylight/light adapted), while 507nm is the peak for scotopic vision (night/dark adapted viewing). But yeah like you said, a good DPSS will likely have a tighter beam, OP will just need to make sure it's not too cold 😁

This ^ If you could stretch from AAA to a single 10440 instead (almost the same size), you could get a 50mw 505nm pocket laser from Sanwu - good price, the host is tiny, and they're really well built. As you're planning to use it for astronomy, I would recommend 505nm as this wavelength is...

Nice! The 520nm is a nice colour isn't it? I was torn between this and the 505nm. Interesting, I'll definitely be taking a look at laserglow in that case, thanks for the rec! It was supposedly a 200mw (650nm) but I'm almost certain the power was underrated. Thankfully it's not that bad, I...

Hello everyone! New from the UK here, definitely no expert, but not completely new to lasers. Owned a few laser pointers when I was a bit younger and have recently started getting back into them again. :) All the recommendations I saw on here for Sanwu pointed me in their direction. Just...
