I've only given it a quick try so far (it's a club telescope, but fortunately only a 5 minute drive!). I did try it without the attachment and I got the expected tiny, sharp point laser dot. When I put on the holographic thing, I got kind of a wider circle, but with two sides of the circle flattened. The photo does show it pretty well despite the bright exposure. Then on one side, there is that "reflection" looking junk. When I put it on the scope, I did get an image on the wall, but just looked like a big version of the same thing. Just to check, I rotated the collimater and sure enough, the image rotated.
I'm wondering if they sent the wrong thing, defective, warped, or possibly doing something dumb!
I may go over tomorrow night and play with the scope and try it out again. Currently working with my own observatory right now - got plenty of scopes here to play with.
Thanks for the loaning offer, I'll get back to you after I give it another try and see what I can figure out. I may take you up on that, but want to explore this a little more.
To my eye, that looks like the laser without the aperture. Have you looked to see if there is actually anything in holographic adapter?
What I an offer:
I used to use the Self-Barlow attachment to collimate my Newtonians. I do a lot of observing and eventually the threads in my laser became worn so I sent it to Howie to see what he could do. When it came back, he had given me a second holographic adapter.
I have my original holographic adapter which I would be happy to loan to you but I believe those were matched to individual lasers whereas the later version would work with any HG laser. Still, it might be worth a try.
If you are interested, send me a PM.
