NGC3324 Gabby

[barx1963]

A view of the northern "lobe" of Eta Carina with NGC3324, the Gabriela Mistral nebula in centre. Taken over 2 nights in Mt Duneed with 100 minutes in 5 minutes exposures in each of Ha, OIII and SII and processed into the SHO palette. Also shows the Pendant cluster, NGC7293 at lower left.

Processed entirely in Pixinsight apart from creating the JPG in photoshop. Tried the new Weighted Batch Pre Processing script and it is a winner. Also new process to get rid of magenta stars (likewise a winner!!) and overall pretty happy with results.

Scope: Stellarvue SVR102T-IS with 0.7 reducer/flattener
Mount: Orion AZ/EQ - G
Camera: ZWO ASI1600MM Pro
Guiding: ZWO ASI290mm Mini, ZWo OAG and PHD2
Filters: 36mm Astrodon Ha 5nm, OIII 3nm, SII 3nm 36mm filters in ZWO filter wheel
Software: SGP and Pixinsight

That's a really nice image Malcolm of a beautiful scene :thumbsup: The cluster is a feature. A larger higher resolution image would look even better...do you have a link?

What Strong Mike said. Beautiful composition.

The WBPP script is described here https://www.tommasorubechi.it/2019/11/15/the-new-weighted-batchpreprocessing/ considerable improvement over the old BPP script. I usually do step by step pre-processing work, but may switch to this now.

The other thing I tried is the magenta stars removal method is shown here https://www.youtube.com/watch?v=KwEpOHQUQu0 from about the 12 minute mark.

That star cluster often makes this images much more pleasing. Good stuff.
