Hi everyone,

Clean sky finally to get this HaOO of the NGC2020
2h40Ha and 2h10m OIII with 80ED 314L+ with CCDT67 @0.75x

Not sure if SII would help bring out more details... what you think?
Hubble-palette instead of bi-colour?

Looking pretty good at the moment Mick

You could always try a sub of SII to see if there is much in the area but regions like this I personally prefer the bi-colour

Thanks Colin,
yes I think get more OIII to reduce noise is better 'time investment'


Cheers,
Mick

A lovely image and one of my favourite nebulas.

More exposure in Ha would be the go. There would be hardly any S11 here and not a lot of O111 (the teal area you already have it about the extent of it).

But the Ha areas are more extensive so there is a gain there to be had.

Love your colouring and the stars.

Greg.

Thanks Greg,
I'll try to get more Ha... I think clipped a bit to reduce noise, but more Ha will help with more aggressive stretch. Yet to master the processing properly

Nicely framed image with pleasing colours.

However it's very black clipped and you appear to have some channel registration (or tracking) issues with the stars.

More data will certainly help - when I did a version of this I found that here was a fair bit of S2 there but it requires a lot of integration time.

Keep going!

Yes Andy, I rushed the processing .... wanted to see it, and broke the rules not to process till next day. I did this 2am and spend only 15min.
I'll re-process once got more data. Had a look at yours, stunning resolution.
The scale on mine is only 3"/pcx. Thank you for the suggestions
