M27 Bi-colour

A few more subs added in this limited imaging period. Ha = Red and OIII = Green with the 2 blended into the Blue channel at 85% OIII 15% Ha. Getting a touch more Shell.

Revision B: Same data but processed in Pixinsight, shows how much more of the shell I could extract. Re processed early April 2016.

Rev C: This is the first object I used guiding, a year on I took this set of data. Plus some 900s subs on another night ( 2 1/2 hours) my set up was not permanent, so it had rotation issues and I couldn't combine it.... until now. Another year on, and not the best of data back then. But never one to throw old stuff out. I'm still amazed at how much extra can be brought out as we learn more. Can't do ought about the dust bunnie that was lurking, but always knew there was more tail to be shown. So M27 HSO with the SII blended at 60% with 40% OIII. Just over 5 hours now.

Rev D: A 50/50 blend of Rev B and Rev C. The core is not as blown.

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.
