Hi All,
I've been imaging SH2-101 The Tulip Nebula for several hours over the past two evenings between 1am & 4am from my back garden in the UK (Bortle 5). After some preliminary processing of the data, I've noticed a faint structure that I couldn't find on other images posted on Astrobin, so I was hoping someone could help identify it. I've blinked through each light frame and can see no anomalies in the area.
Other stacking, the image below is simple unlinked STF with no additional processing and the structure clearly visible.
Any ideas?
