Whirlpool Galaxy M 51 - five hours total imaging

Shot the Whirlpool Galaxy a while back but with the SeeStar S50 smart telescope. Easy to use but image quality isn’t quite as good.

And also shot it with my Canon EOS R6mkII and the Tamron SP 150-600 F/5-6.3 DiVC USD G2 A022 at 600mm and despite getting over six hours data over two nights it’s not nearly as good as the Askar V and ASI585MC-Air version from last night.
