Only my second attempt of this wonderful emission nebula NGC 3576 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 medium sized Newt , even with Narrowband filters , this camera is so sensitive.
Captured over 2 nights ( just over 6 hrs integration)
