4 Panel Rosette Mosaic - Caldwell 49

Encompassing five NGC objects, NGCs 2237, 2238, 2239, 2244, 2246, the Rosette is one of my top 5 favorite objects. But shooting at 2563mm I was forced to use a four panel mosaic. The mosaic was stitched using the PS CC automate photomerge command. Pre-processing was in CCDStack to produce the four panel masters that were finished fully in PS CC.

221 twenty minute subs for a total of 73.7 hours. 79 Ha, 66 OIII, 76 SII. I would like to have added more time in some of the panels but the season is coming to a close and roof open time is fleeting this Winter.

The color mix is straight SHO. I may try some alternate mixes down the road.

EDIT 30.12.2019: Added new data and re-processed completely. My goal was to get the noise and quality up so I can do a large print for my home. For this version SHO master panels were joined in PS and then the Ha channel was used for luminance.

Description: Added 18 hours of data, complete re-process. Four SHO panels were joined in PS and then the color masters were re-combined with Ha as Luminance and SHO as color.

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.
