Your long focal length refractor is probably f5/f6 at best right? That bears no comparison to a (relatively) wide lens at f1.2!! In the real (affordable) world, you’re never going to get perfect stars without halos etc at f1.2.
There’s a reason why equatorial mounts are pretty much a requirement for astrophotography, although you could try stacking a series of 15 second exposures on a tripod at say f2.8-f3.5 and see how you go. Even if the individual frames are underexposed, you should be able to pull something better out of a stack of images.

Thank you Phil much appreciated.

I know your work so this comment is really well appreciated and believed!!
My refractor (TOA-150 now replaced with a Mewlon 250CR) had incredible performance.
Last paragraph is a "damn good idea" I shall try it.
