M13 - first attempt...

[Simms]

Nothing too special - lost some colour in the core - so I am thinking longer exposures with a lower ISO? Any advice?

Wish I could give you advice but all I have are compliments since I couldn't create an image such as this. Great detail!

As a first go Mark, It's blumming brill. It might be worth giving a lower ISO a bash.

Very nice....cracking first image

If you can guide accurately for longer, give it a go at a lower ISO, but it's possible you may have more data there anyway.

How did you stretch the image when you processed it?

What are the imaging details?

Cheers
