Looked on Amazon but they don't seem to sell them anymore, I'll have to do some googling. 1mW Red Class 1?

Yes ideally, I ordered 2 and when both came they were 5mw, and advertised as 1mw, but I did not dare try them, just returned and looked elsewhere on Amazon, but I can’t find my order to send you a link, it must have been on my sons account a year or 2 ago….

Yes, that’s exactly what I got, and if it’s a 1mw as advertised then all good, I have also used a laser taken from a laser collimator, that worked well too, and made for the job…👍🏻

Oh yes didn't think about using a laser collimator. I've ordered one, it was only £4. Also ordered a kitchen unit for £30 that's 600x350, should work. Just need to 3D print the holders.

Would this be safe? Only laser I can find on Amazon

Hmmm, again that’s a 5mw laser…

But you would think that as it’s in an Astro related  item it should be ok….🤔🤔

Yeah that's my concern also. I've actually ordered a cat laser pen toy from amazon, should arrive today. Takes 2 x AAA but not sure how I can determine it's output power....

Well I'm struggling with my jig. Cutting the hole with a hole saw leaves the surface ever so slightly uneven and means the camera wobbles. Not sure how to fix that and with it wobbling, it's impossible sort out the tilt. Any ideas? I've tried the camera on the surface before I cut it and it was completely flat.

Yes I had that issue and sanded it flat, then I 3D printed a holder for my imaging train, it does need to be flat, doesn’t matter if it’s not perfect parallel to the base, close is good enough,  but it’s needs to be flat, as you have found out the camera can wobble…
