NGC 3576 Statue of Liberty Nebula in SHO

[Startrek]

Only my second attempt of this wonderful emission nebula NGC 3576 Statue of Liberty Nebula in Carina
First time was with my 2600MC OSC back in 2022
Captured over 2 nights under Bortle 8 skies and a full moon , the Antlia 3nm filters were really put to the test . I was very happy with the level of detail using 3 min subs however star cores were still blown out to some degree . 2 min subs may have been a better option. One thing I’m finding with the 2600MM , you don’t need really long subs when using a medium sized Newtonian , even with Narrowband filters , this camera is so sensitive at medium gain.

Captured over 2 nights ( just over 6 hrs integration)

Thanks for looking
Comments welcome

PS: I’ve added a version using Film Dev for final stretch in lieu of AutoDev ( Film Dev seems to control the fainter outer nebulosity areas marginally better than Auto Dev in relation to brightness and noise )
