Lion Nebula or Triceratops Nebula Sh2-132 SHO Hubble Palette RASA8 (Brandon Tackett)

Lion Nebula or Triceratops Nebula Sh2-132 SHO Hubble Palette RASA8

While still trying to image through somewhat lightening smoke here in the midwest, I was able to capture a the Lion Nebula over the last several weeks. I have been more tired lately and just spend an entire night on each filter.

As I was editing it, my son said it looked like our family aussiedoodle Astro. As I continued to edit, it looked more an more like the little triceratops Sara from Land before time. I guess my mind is still on kids movies as that permeates our season of life with little kids.

My normal method for processing left me wanting and I tried a new method with tone mapping for this image with better than expected results. I appreciated Eric Coles and Tim Hutchison with their recent tutorial on the Astro-Imaging-Channel. I used a Ha luminance layer and then used the Ha stars. I over cooked the star reduction slightly on this version and will have to go back and work on it later.

I fell into the normal trap of trying to make my version look like really superb one on astrobin (Terry Hancock's from earlier this year) with better skies and better equipment. I keep trying to find a way to only add the medium and large stars back in while eliminating the small stars that distract from the nebula which make his version pop.

There is not a whole lot of details about the nebula that I could easily find. It's located 10k to 12k light years from earth in the constellation of Cephas. The large Hydrogen and Oxygen nebula clouds are being irradiated by large super hot Wolf -Reyaet star WR 153ab.

Title: Dec 2022 Revision with Updated Processing Techniques with Increase Detail

Description: Full redo edit. Used blurX and NoiseX in the non linear phase. Also used SPCC for stars by applying it's narrowband application and stretching those stars to then blend with the SHO stretch. The Detail improvement is astonish at both small and full scale.

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.
