Hi there!
I'm relatively a new user for this very fast newtonian by Sharpstar.
I wish to join with other users because this intrument is quite rare and the setup is not easy.
I hope to meet other users to exchange specific experiences, positive or negative, or issues/troubles using or setting up this newtonian.
Thank you in advance for any comment.

Don't know anybody who owns that newt but can't see why it wouldn't be a great performer.

@Simon Todd has one that he uses to create stunning images!

He has a number of good articles on his website regarding it too

Worth a look!
I have used his collimation guides etc as I have the Sharpstar 15028HNT - Similar, but different in some ways to your 20032PNT

I don’t have the Sharpstar but I do own a F/4 Newt that I use with a 0.75x focal reducer with brings it down to F/3 or so.

I struggled mightily with collimation and tilt, sold the reducer-corrector and bought a 1.0x corrector for it. Then after several years of working at F/4 I bought another 0.75x reducer-corrector for it and tried again. I seem to have it working.

I posted everything I learned that I thought might be useful to someone starting up with a fast system of this sort here.
