Here's another 3 panels I shot tonight. Still playing with the QHY8 and my Pentax lens. I held the front of the lens into a centering ring this time so I have less flop but still need to tweak things. Anyway it's a better result than my
previous attempt. That's 10x10min for each panel so abit under 5h.
There's a bigger one
here. Had to crop a bit to fit the three stiched in one panorama as it's a very big area. Maybe third time lucky I manage to get a flat field with no coma across the whole pic.
PS: Well I managed to squeeze some more subs before the clouds rolled in around 22:00. First panel same field center on Rigil Kent but I closed the aperture of the lens a bit and it made a huge difference. Reference frame attached below. Big fuzzy in the top left is Omega Cent. Still a bit of tilt on the right side but very manageable. Big thanks to Greg

Tomorrow I should be able to reshoot the whole milkyway this time as it clears the roof. Whoohoo!
