I have laser based telescope finder (525nm, approx 125mw) available pictured at the link below. The small (less than 1mw
) silver-coloured laser pointer also pictured gives you an idea of comparative size

This unit uses 2x C cells and comes with a dove shoe for quick telescope mounting and bracket.
Also be aware, if you disassemble the unit and use it as a laser pointer you may be in breach of State laws. $950 inc bracket
Yes it will burn a hole in PVC tape etc...so it's not a toy!
Very hard to import these days without prior customs approval, also, unlike cheaper units it has a full duty cycle and does not need to be turned off after a
few minutes to avoid destroying the diode.
