Light: 23 x 600 seconds (originally had 36 but lost several to clouds)
Dark: 10 x 600 seconds
Bias: 10 x 0.3 seconds
Flat: 10 x 0.5 seconds
Dark Flat: 10 x 0.5 seconds

Pre-Process:
- WeightedBatchPreProcesssing script
- Subframe Selector
- DrizzleIntegration

Post-Process:
- Dynamic Crop
- ABE
- STF - HT
- Unsharp
- TGVDenoise
- StarNet2
- HT with lum mask

I have to say that StarNet V2 is a real step up from the original version!

---

For the sake of comparison, version 2 offers a 2x2 binned image. The seeing has been such that I think the 2x2 binning provides better detail than 1x1.

Same hardware as before.

Light: 16 x 600 seconds, binned 2x2 (originally had 24 but lost several to clouds)
Dark: 10 x 600 seconds
Bias: 10 x 0.3 seconds
Flat: 10 x 0.5 seconds
Dark Flat: 10 x 0.5 seconds

Pre-Process:
- WeightedBatchPreProcesssing script
- Subframe Selector
- DrizzleIntegration

Post-Process:
- Dynamic Crop
- ABE
- STF - HT
- Unsharp
- TGVDenoise
- StarNet2, preserving star mask
- HDR on starless image
- PixelMath to recombine starless image with star mask
- TGVDenoise a second time

This approach seemed to give better detail than just doing HDR on the original image.

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.
