Description

Hi,

Thank you for watching my version of Helix !

This is my first image with my new camera QHY268M. I used mode1 gain 56.
The image is a crop at native resolution.

I tried to make the faintest extensions of the nebula visible without burning the core. There are much deeper version of this object on the web but I was happy of what I could get with 8h of Ha : my goal was to get the bow shock at the bottom left on the image.

I found it difficult to process to keep a feeling of transparency. I could strech more and saturate the colors but it would make the rendering very different. I tried to keep a balanced rendering.

Hope you like it, looking for your feedback.

Thanks for reading

Yann-Eric
