I took the Ha back in 2022 in Swanley (chez Dave Taylor), but as the rest of the data was pretty poor from that due to clouds I forgot all about it.
I took it again at Cairds DSC back in October 2023 in LRGB.
Both attempts did not yield much data.
Swanley 2022 I wasn't able to use the Lum but I managed to use 11 x 600 Ha.
Cairds Lum 10 x 600
RGB 10 x 600 each
total 3 hours 20m + Swanley 11 x 600 (1h 50m)
Grand total is now 5h 10m
Still plan to get more data on this if I can but big tree in the way at home for Ha and the rest would need to be done at DSC.
This is the image from Cairds in October.

This is the revised image with the Ha added.

Following a tip from Olly Penrice on SGL, I have now treated Rigel with his star bloat reduction technique in Photoshop.

Very nice Carole. Tough object so low in the UK skies and with Rigel in the frame shining so bright.
