M78 - LRGBHa

Revision title: Super Luminance, Among Other Things

Here's one I really can't get very easily at home. I only had two nights with it under a dark sky, and it's a bit early in the season for Orion. But I'll take it. It's one I've wanted to get a decent shot of since I started doing astrophotography lo these three years ago.

I captured this data at the Nightfall Star Party in Borrego Springs, California the last couple of nights in October. This was my first star party. We drove the RV three days to get there and three days to get back. My motivation for going was to see Ron Brecher, my one-on-one astrophotography teacher for the last two years, deliver the keynote and finally get to meet him in person. Unfortunately, Ron had a mild heart attack (he's going to be fine) a couple of weeks before the event, so he was unable to attend. But any excuse to load the telescopes into the RV and go somewhere dark is enough for me.

Description: I missed uploading this when it happened, but it was very nice for AAPOD2 to recognize this picture. It's not easy lugging a C11 and a 10u GM1000 3,000 miles!

Title: Super Luminance, Among Other Things

Description: Recently, Ron Brecher taught me a stunning technique for enhancing the luminance channel of an LRGB image by stacking the R, G, B, and L masters together to create a "super luminance" master. While it still works great on images with a good deal of integration time, it's extremely helpful on images like this one that are captured over only one or two nights on a dark-sky trip. Typically, I see around at 10% boost in SNR using this technique, but on this image, it was closer to 20%. That makes a very big difference--especially in the darker, dustier areas of the image. But overall, it really helps smooth out the noise.

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.
