witches broom, slight coma issue

[Stardust]

I tried the Witches Broom again with a reducer, but looks like it has introduced a bit of coma on the bottom right.

The increased field and faster f ratio are a real plus but any idea what to do about the coma. It is a flat field at the native focal length.

This is only 5x10mni HA & 4x15min OIII, as that's all I could get last night and a quick process more to check the flatness of the field than anything else. 

any thoughts welcomed

Still, a very nice capture. Thanks for posting.

I put the image together a different way, spent a bit more time on processing and think I'f reduced apparent coma, doesn't look as bad to me.

I'm quite pleased at this for the short amount of data, wont get chance to add any more this week looking at the forecast

Very nice result, especially the re-processed image.

Go well!

Nice result David, I like the colour, I've seen a few images of this with really bright red which looks a bit gaudy.

I put the image together a different way not sure if it's made any difference though

Yes it has made a difference (on my monitor anyway).  I prefer the second without the greenish tinge.  Very nice.
