Description

I went back to this target on the last clear night we had here on June 1st. It has been cloudy since then and looks like the clouds will last a while longer.

I think I got much better images now that I have had some practice with the equipment and software. This revision is from an entirely new set of subs. I tried combining the older sessions with this one but the earlier data just reduced the quality so in the end I decided to just stick with the new set.

I have been experimenting with drizzle in Siril. I don't exactly know what it is or what it does. I've heard recommendations to do it, so I tried it. I can't say whether thats an reason for any improvements in this revision over the earlier one. I think it's mostly due to better quality on the capture side of things.

Thanks for having a look! Please leave a comment, especially if you have any tips to help me improve.

Title: M 51 - The Whirlpool Galaxy

Description: I went back to this target after improving many of my skills with the equipment and software I used to capture this image. I think this is an improvement. Still working on the stars though. I did not extract the stars to process the galaxy and stars separately. This time I focused on bringing out more detail in the galaxies and didn't worry about the brighter stars so much. They ended up getting cropped out anyway. This is a whole new set of subs. I tried combining these with the earlier set but those just brought down the quality of this new set.

Thanks for having a look. Please leave a comment, especially if you have any tips to help me improve!
