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?
