IC63 RGB Ha as lum

Revision title: toned down saturation on yCas even though I like blue.

This image is a continuation of my testing of the Antlia 5nm Ha filter. This RGB version with Ha as luminance. I fooled around with blending in some Ha, but ended up not doing that as I like the greyish light Ha whisps instead of the traditional reddish. This is actually a 40% overlap mosaic...for testing I wanted yCas in the image...lots of processing to remove halo. I wanted more data of course, but the weather has not cooperated. Wonderful for the drought though! Green hills again! Hadn’t seen that in the past 2 years.

Using BXT on the unstretched Ha image brought out tremendous detail…kind of seems it has a tiny bit of “Hubble” like quality. All this from my B7, 18.45, backyard. Seems astonishing to me what we are able to do with the equipment and the software.

My verdict on the Antilia 5nm…for the price it is a winner! If I want better, I will have to pay exponentially more, like 4x.

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.
