M42 - Reprocessed

Recommended Posts

I decided to attempt to completely reprocess my data of M42 from 23rd/24th November to try and get the core better and less blown out. I think I achieved it and quite happy with it now   :)

Any thoughts comments welcome.

The core is a vast improvement. But do think that its a touch heavy on the magenta.

Thanks I try and check the colours on my computer, mobile and tablet to try and get the best colour I can as on my computer it looks fine but then on something else too saturated, frustrating really.

Nice work though i would agree that the red channel may be a touch too strong.

You have done a really nice job of transitioning to the core. Tough decision between the PI and PS versions, the PI version has more contrast and detail but at the expense of a little more noise by the looks of it. Either way, great images!

Thank you,

The focuser isn't too bad, I tightened the tension and that improved it a lot. At the moment focusing is fine as I am using Capella which is quite low in the sky at the moment, there is a tendency for it to slip slightly if I am focusing on a star much higher in the sky like Deneb/Vega and it is a bit more fiddly to get it right, but I really don't find it a problem if I support it and tighten the focus lock knob when I am happy with the focus and it will happily stay in the same place all night.
