The Puppis Mountain

I decided to revisit this little observed "Mountain" feature in Puppis as pretty much the last thing I did before I headed overseas from the Hermit Kingdom (NZ) to see friends and family in Sydney. Consequently on my return this evening, I was quite excited to see what I had captured.

Overall, I am quite please with the result. It is my first "yellow" nebula, with Ha and [SII] contributing equally. What little [OIII] there is, avoids the shock front of the nebula giving a rather lovely "boiling" feel to the main part.

But this object is very faint, and even in NB, the moon was problematic. It has probably gone until next year, but until then this we have do do.

Ha 30 x 600s
[SII] 15 x 600sec
[OIII] 15 x 600sec

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
