Greg, another beautiful capture and processing, colors right to the core!!  Nice work!   That's on my list.. you should see my earlier attempt with my 8" SCT and T3i from a decade ago...    Just gorgeous!

@terri Thanks, Terri.  This was the first globular cluster I imaged.  Not quite as easy as I thought to process!  

Do you have the image you took with your T3i?

Greg
