If the Saxon laser you have is out of collimation and has no feature for adjusting, return it!

You wouldn't see that return beam/image on the Barlow target if the primary is way off, so that's maybe the cause.

If you run up against some obstacle, bring the scope (or just the OTA) to a local club meeting (ASV, MPAS, etc) where I'm sure you'll find someone to help.

I am still a little perplexed about not being able to see the center spot shadow on my target on the end of the barlow. Perhaps the collimation is so out of whack that it will be invisible until I do the secondary etc as suggested by all of you good folk. Thanks heaps for your advice.
