I am very pleased and enamoured with the narrow band data for M20_21 that I've just pulled out of the pre processing can that I felt the need to share with others that may understand my excitement. I tried showing it to my better half but I did not sense the same enthusiasm < sigh >.
Attached is a copy of the Ha/OIII/SII channels to which I have cropped and given a very quick stretch only. I felt that there was a lot of interesting detail as they stand already so that it was worth posting at this early stage. I can already see that the Ha channel is going to be a challenge due to the very high dynamic range. Just proves again that no two images are the same when it comes to processing.
Anyway, for others that suffer the same compulsion as I do may you enjoy the data.
Know exactly how you feel Rodney, great stuff and great looking data mate Hope it comes together for you, assembling a pleasing looking narrow band image of the Trifid is no easy task

Thanks Mike, I don't have much of a feel for where this one will go nor how I may get there but we shall enjoy the journey all the same
Oh yum! The [SII] looks especially fine. There is a large faint arc centred around the top right corner of the image which is relatively strong in [SII]. Perhaps it is a part of an old supernova remnant, nothing to do with the Trifid.

Can't wait to see how this one comes together.
Thanks MnT. I’m going to have to do some research now on neighboring SNRs in Sagittarius
Good looking data there it seems. Keep at it. A narrowband version and a Ha OIII OIII version in the works?
Thanks, to start with will be attacking this on as an SHO process. I have some RGB as well and want to try adding that in so will wait and see. I have to stop getting distracted on other projects though. I have at least three data sets in the bag now waiting for attention
I've been staring at the screen too long so it is time for this one to emerge into the light of day. Our Trifid has been nutured and cared for and it is now time for it to move out and meet others. We would appreciate your thoughts on the new addition
Mike S. made the observation that preparing a narrow band image of the Trifid would be " ... no easy task" ... He was right
Details of image acquisition can be found in the Astrobin post here. Click on image in Astrobin for high resolution.
Comments and critque welcome.
Cheers,

Thats great Rodney,
All over the top of my head; The 3 narrow band mono data's are indeed interesting ?
I like the resulting color too - no bias 'ere
-------
A Question tho, I am uneducated in the varieties of capturing narrow-band sets and what is doing for final images, - Can I ask if you added the RGB's to a combined of all 3 Ha/OIII/SII channels; I guess yes, looks like data from all in the color final.
IF so, does you stack the Ha/OIII/SII channels 1st separately and then add the rgb's ? Or do all rgb's & Ha/OIII/SII channels stack together
Cheers
