"Mons Puppis" featuring NGC 2477, NGC2451

This is a rarely imaged area of Puppis. The nebulosity here is large, dramatic but very faint.

Referred to by some as "The Mountain", I couldn't resist having a go at Mons Puppis or the Poop Mountain.

I also wanted to try an OSC image as 1) there aren't any of them on AB and 2) there are a couple of rather lovely star clusters (including a Caldwell object) in the frame and I haven't learned yet how do to stars properly in NB imaging.

Obtained almost 3 hours of subs on our 4hour nights here, before dew/fog intervened (I suspect global warming will ruin AP before satellites).

The emission is, as expected, very faint. But I foo like the deep red edge "shock front" to the nebulosity with a yellower "wake". Since no noise reduction was needed, I suspect that I am limited by the Milky Way background here, rather than the sky.

That is probably a reason why there are no OSC images of this area, but I hope folks will find it instructive.

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.
