Veil Nebula Complex, OSC (UHC-S), 2015-1016

This is my first try at a big mosaic. I imaged the whole thing using Sequence Generator Pro’s Framing & Mosaic Wizard, for which I am doing the free trial right now. This required 9 frames with my setup (Meade DSI IIc on an Orion ST-80 with an Antares 0.5x focal reducer), and I didn’t really get enough integration that way. I combined those frames with Microsoft ICE, and immediately it was obvious that the colors didn’t match up well among the various frames. I used Photoshop CC 2014 to add better data in the regions of high nebulosity from 2015 and this year, and tried to fix the color mismatch using Gradient Xterminator along with layer masked hue/saturation and color balance adjustments, not too successfully I’m afraid. So the result is still not too satisfactory, but it’s a lot better than my previous attempt to get the whole Veil Complex using my finder/guider as a main imaging scope. I’ve still got a lot to learn about how to process this kind of data, but it was fun to work on. I’m impressed with the Framing & Mosaic Wizard and plan to purchase that extension.

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.
