Greg,
I totally agree, Newts give sharp, crisp , pin point looking stars if you have everything working right ( I solely use newts )
Refractors, from the hundreds of images I’ve looked at over the years tend to give “soft” looking stars particularly around the edges , almost a halo type look
I suppose it’s mirror reflection vs glass lens refraction that distinguishes the appearance of stars between the two.
On some of the bigger stars my diffraction spikes can extend way out in the background which I don’t mind a bit. A lot of folk hate diffraction spikes but not me
Cheers
Martin
