Trev,
Is this the same Trevor from Perth ?
Wow what a difference from your previous work, colour is pretty damn good , maybe a tad too bright or saturated on the Ha but it’s all subjective anyway. Love the blue !! this is stereotypical Hubble palette.
Image seems a tad noisy though ?? How many hrs ? Do you use calibration ?
Nicely processed considering this is your 2nd attempt !!!
Onwards and upwards from here !!
You can see from your Hubble images that details in the objects structures are more accentuated against the contrast between Ha and Oiii.

NB: One can get carried away with colour , brightness and saturation with Ha and Oiii in Hubble palette which leads to masking fine detail in these emission nebula. Another problem is that images can start looking like 70’s Pop Art. A conservative approach is recommended.

Can you throw some clear nights our way , Sydney and the East coast has been plagued with cloudy nights for weeks and weeks

Well done Trev !!

Martin
