m45

Hi everyone. I'm hoping someone will be able to shed some light (sorry) on those annoying halos. This is a Newtonian reflector. Could this be the cc I wonder? Didn't have time to test without but then again, if I did, there'd be something else to complain about. TIA and thanks for looking.

Could it not simply be the fainter fringes in the diffraction pattern becoming apparent due to stretching of the low intensities needed to bring out the nebulosity?

Cracking image, I would say

I like it - very sparkly and in spirit of the season

Love it.

I've been imaging M45 too as I can't get the Horsehead which I'm gathering data on until late because of my neighbours house.

I like your image. Sure, there are halos but these are very bright stars which throw up stellar artefacts which we see in all sorts of bright star images. The halos are probably internal reflections and the spikes we know about from spiders. I'd rather concentrate on your tight focus,  crisp, tight field stars, well colour-balanced background sky and well-judged black point. Good image. There it is.

That is a beautiful image.... I'd definitely print and hang that if it was mine!

It is a beautiful sparkling image, and in many systems halos from bright stars are unavoidible. Not even the Hubble Space Telescope can produce halo-free images of bright stars. Here is an example from the Hubble site, and the Hubble people are apparently proud of it:
