First Light - Rosette Nebula

Revision title: Pulling out a little more.

I’ve had this telescope and camera for a couple of years. I am new to OSC imaging with this kind of setup. I started with a DSLR, but went straight to narrowband imaging from there.

I found the OSC process workflow challenging….not to mention getting used to dealing with light pollution.

The actual first light was technically a shot of my neighbor’s roof through the window in my office. This was the first real project in the dark.

I was never satisified with the original version. As you can see, I have revised it multiple times. I hope I can continue to improve the workflow and get better results, going forward.

PixInsight Workflow

Pre-Processing:

WeightedBatchPreProcessing - 2X Drizzle

Post-Processing:
Rotation - 180
GradientCorrection
BlurXterminator - Correct Only
ImageSolver Script to Platesolve image
SpectrophotometricColorCalibration
BlurXterminator
TGVDenoise
NoiseXterminator
StarXterminator - create separate starless and stars images
HistogramTransformation to stretch stars
CurvesTransformation on stars to adjust saturation
GeneralizedHyperbolicStretch on starless image
LocalHistogramEqualization
PixleMath to recombined stars and starless - ~((~starless)*(~stars))
CurvesTransformation to adjust saturation
MorphologicalTransformation - slight star reduction

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.
