NGC2175 The Monkey Head Nebula

Hi folks:

When I started this image, I realized rather quickly that most of the exposure time was going to be allocated to the S-II and O-III. These channels are incredibly dim in comparison to the Ha in this region. At some point during the acquisition, I had over 10 hours of S-II and O-III and just 3 hours of Ha had higher SNR! The total integration time of 52 hours helped bring the SNR higher and keep processing at a minimum. I made a conscious decision to keep brightness to the minimum and maintain as much of the dynamic range as possible. There is an incredible amount of detail that is composed of slight variations of brightness and did not want to lose those for the sake of a brighter image. The lower left section does show even with this minimal amount of stretch...

The image is presented in SHO colors, via Astro Pixel Processor's Hubble Palette 2 value, with data normalized with the add-scale parameter. Minimal increase in saturation and stretched using the 10%BG 5 sigma, 0% base to preserve dynamic range. Taken over 17 nights in January and February 2024.

Enjoy in full res!

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.
