82% Waxing Gibbous in IR+RGB (lefty7283)

82% Waxing Gibbous in IR+RGB

I saw that ZWO has a ~$25 IR pass filter for sale, so I bought one to see how well it could improve my lunar images. As the wavelength of light gets longer it gets lass scattered by our atmosphere and therefore produces a sharper image (this is true at least for visible through near IR wavelengths). [Compared to my red filter, the IR filter (left) does in fact produce a sharper image](i.imgur.com/03OtLq8.png). The IR filter was used to produce a luminance image for a color RGB images in this image. I'm pleased with the final result, save for some color fringing on the brighter craters. I plan on keeping this filter in my wheel for moon shots at least until my Sulfur narrowband filter comes in. Captured on March 5th, 2020.

**Processing:**

* Best 15% of frames stacked in Autostakkert with 3X drizzle

* Registax wavelets for sharpening

* Photoshop to align all channels, combind RGB channels into color image

* LRGBCombination with IR image in Pixinsight (with chrominance noise reduction)

* Autocolor in Photoshop

* Several [Curve](i.imgur.com/a6nwHqi.jpg)Transformations in Pixinsight to adjust lightness, color balance, and saturation

* LocalHistogramEqualization

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.
