Would a 800 mW green (532nm) laser or a 1 W blue (447nm) laser be better and more visible for star pointing? Would both be capable of burning wood?

Both would be capable of burning wood. 800mw green laser will be very bright a lot brighter than a 1 watt blue laser. A 1 watt blue laser can go as low as 140$ but a real 800mw 532nm laser will be very expensive. If you want a powerful green try out jetlasers. A 1 watt blue laser can be bought of this forum in the by/sell/trade section. You will need goggles for these lasers. If you are buying a laser for star pointing you should get a 30-50mw green laser from lazerer.

i would buy one laser for star pointing and one for burning. a 30mW green is about perfect, from what ive herd for star pointing. and then for burning buy a 445 and some good safety goggles

Either is overkill for star pointing. For that you need 30-50mW MAX.

Green would be a lot more visible.

Both would burn wood when properly focused.

Chances are the green laser will not be anywhere near 800mW though, since I imagine you're looking at some cheap chinese site?

Have you invested in proper safety goggles? Even a fraction of the 1W or 800mW is enough to leave permanent damage. Literally faster then you can blink.
