Bravo for rising to the challenge of imaging  a broadband target like M51 from a Bortle 8 location.👍

Nice, the Askar scores again!

Thanks all! I find the shot a bit underwhelming, but perhaps interesting and useful as an example of what this target looks like with a small refractor. It's got me lusting after a bigger 'scope though 😝
