Melotte 15 (Wanda Conde)

Melotte 15

It has been a terrible year for imaging. First we had the Saharan Dust Layer; then an active hurricane season, tropical waves, troughs, etc. kept our skies cloudy for most of the year. Finally on late November we had a 2 week weather window and I tried to make the best out of it.

My backyard is full of obstructions and I can only image objects of northern declination and many of them only until they reach the meridian. The San Juan metropolitan area is north to where I live and its light pollution complicates things even more.

I've always wanted to image Melotte 15. I knew it was going to be hard because: (1) it rises only 46 degrees in the sky, (2) it is located in the area where light pollution is the strongest, and (3) it "hides" behind a palm tree after the meridian flip. In spite of all this, I gave it a try and hoped for the best. I have to say that I was expecting it to be a lot brighter than it came out. Still I like the result I got. I hope the weather improves soon so I can add 6 more hours and RGB stars. Until then, here it is....

Title: Melotte 15 - Full Reprocess

Description: I decided to reprocess this image using starless images as a starting point. I had tried that technique before using Starnet++ but in this case the masters I got were so full of leftover artifacts that I gave up and processed it without removing the stars. I was pretty sure I could do better....Recently I purchased Russ Croman's Star Exterminator and I gave it a try with this image. I have to say I was super impressed with the result. By using masters without stars I think I was able to lot more of the dust cloud that surrounds that star cluster. I regret I don't have any RGB stars to replace the narrowband ones, therefore I tried to add color by trying different narrowband mixes. I hope you like this version as much as I do now.

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.
