The Rho Ohphiuchi Cloud Complex- A 9 Panel mosaic shot in Marathon Texas at the Marathon Motel & RV Park during the new moon in June over the course of 4 nights. Some of the most beautiful colors in our galaxy are found in Scorpius around the Rho Ophiuchi Cloud Complex and I was happy to finally catch their photons on my telescope!

Technical Details:

12 x 180s L

12 x 180s R

12 x 180s G

12 x 180s B

Flats taken after each session. Bias and Darks from my library.

Equipment Dtails:

2 x William Optics 132 FLT 5.5 Telescope w/ Flat 7 @ 5.6

Lum & Red shot on scope 1, Green and Blue shot on scope2

QHY 16200 x 2

QHY 5LII Guide Camera on WO 50mm Scope

Calibrated, Combined, and Exported in Pixinsight. Levels and Color adjustment in Photoshop. Plate Solve from Pixinsight.

Panel Process:

-Dynamic crop per panel

-Batch PreProcessing used to combine flats, darks, and bias frames. Cosmetic Correction used on each panel.

-Dynamic Background adjustment per panel

-Photometric Color Calibration per panel

-Histogram Transformation applied

-Noise Reduction via SCNR Green Channel

-Export to master TIF for full color panel

Mosaic Process:

-Each Channel solved via Image Solver in Pixinsight- Tedious but effective and ensures a valid plate solve.

-Saved as .Tiff & .Xisf per channel

-Mosaic By Coordinates Script ran on each channel master to create a master per channel.

-EXTREMELY GOOD NOTES taken per panel for image center and Photometric Color Calibration (If you don't, you'll redo the process over and over- Sky Safari is your friend.

-Combination via Gradient Merge Mosaic per channel

-Optional combination of LRGB targets yield less color & slightly better combination to my eye. YMMV.

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.
Dismissals 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.
