Trying to capture Ek5 from London....and emulate Peter Goodhew's and Sven Eklund's image https://app.astrobin.com/i/fdv55d (https://app.astrobin.com/i/fdv55d). Acquired towards the end of astronomical night and pointing above London's LP dome; not the best conditions for a - very - faint, extended planetary. Most of the narrowband data comes from a dualband filter.

Roberto
As usual a fine set of images Roberto, I might have to miss out the graphical images but will point members towards the Forum.
As for Ek5 - HaOORGB from London, Total integration: 98h 5m
That's an incredible exposure time for a single person to collect. I was not familiar with it, but looked at the link you attached. As you say a real challenge from South of London.
Carole
Brilliant images Roberto
Especially the Sun with large prominence
Brillian set of images. As Carole mentioned, 98 hours integration time, thats impressive.
Clear Skies
