M51, the Whirling Dervish, or why I need a longer FL

[900SL]

My first target was the Sunflower, but it hid behind a tree to the SE.

So the back up was M51. 90mm F6 540mm, 1.0 x FF, TS Flat2. 150 x 90s OSC, 533MC Pro

No noise reduction, just Siril processing. I need a longer scope for this Galaxy lark. Here's a crop
