I've always known about Andromeda's extended halo, but to what extent Andromeda stretched out was of exciting news to me.
Last year I had processed a 9 hour image of Andromeda (2 hours in Lum, 2 hours in Ha and 1h 40m of each in RGB) and had noticed some structure in the Ha band that got me a little excited because I had not seen it present in other amateur images. This year I decided to reprocess the data starting with the Luminance and to my surprise I noticed faint underlying structure. My first reaction was a poor calibration or poor gradient removal via PixInsight's DBE because it was significant.
I went ahead and processed and after inverting the image I could clearly see some structure. My posting on CloudyNight's CCD forum confirmed that it was in fact structure (Thank you, Hiro, Leonardo, Mike and Rob [aka pfile]) and my excitement grew further.
Here is my luminance data and trying to get a proper colour image sorted out, but not having much luck ... I'm not very good with LRGB work.
- luminance process
- inverted and exaggerated the stretch to highlight structures
- combination of my original Andromeda and my latest... much better, but still not quite there. Happy ... for now ;)
