NGC 2174 Monkey Head Nebula in 10 mins (Mike Dobres)

NGC 2174 Monkey Head Nebula in 10 mins

Revision title: HOO version

The Monkey head nebula in orion just 6,400 light years from planet earth. A very strong HII emitter that makes capture with the L eXtreme filter very easy. It just popped out after a few minutes. Captured and stacked as a livestack in Sharpcap, then processed in Startools. Needed very little processing. Most of the detail was already visible in the Sharpcap livestack save-as-seen.

Very easy to see the eyes, mouth and brow of the monkey. I actually think its more like a neanderthal head than a monkey head.
The original version was stacked in Sharpcap and processed in Startools-

January 2023: Many cloudy nights and time on my hands led me to try re-processing this image
Version C was restacked in PI, and only 219 of 246 of the 4 sec subs were integrated. So total integration time is now down to less than 9 mins! Not too bad Processed in Startools. Was less aggressive with noise reduction and managed to bring out some of the OIII signal in the center of the nebula.

Versions D and E the same PI stack used in version C, but used PI DBE, BlurX, Noise X and curves.

Version F: skipped DBE or ABE, straight from WBPP to BlurXt, NoiseXt, Curves then GradientHDRC - but still needed to revert to Startools repair to remove coma in corners!

Version F: HOO version using Pixinsight Narrow Band Normalization process.

Title: Pixinsight stacked and processed with BlurXt

Description: Use of BlurX and Noise X really helped clean this image up!

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.
