I like this galaxy, which is quite unique compared to others in terms of its twisted and spiral shape. Still a bit noisy after ~18-hour exposure. Will try to add another night on this target.

Very cool- worth a compare with my image earlier last year https://www.astrobin.com/ua0vuq/C/

 

I need to redo as its a bit overly sharpened.

I did not sharpen my image too much. The only things I did were boosting contrast in the core, increasing the color, and reducing the noise.

 

You did >50 hour exposure which is amazing!

Greetings Yuexiao from your neighbors in Amarillo, where the wind today has been horrific. Your image of what we call the Sea Shell Galaxy is beautiful, with an excellent job bringing up the core details and the spiral twists without exaggerating anything. The large barred spiral is also well done---which is tough without creating too much background noise. You are producing some impressive work given the reduced elevation of your site compared to us at Deep Sky West, and this target is top on our list for next season. Thanks for the inspiration.

Wonderful image, very deep and with the RC8 :waytogo:
My best effort was almost 24 hours but from my balcony with strong LP.
Your image looks great!

I also imaged these galaxies from west Texas, not too far from your site (Crosby County).  It's amazing how deep you can go on the background galaxies with super-dark skies to help.  Unfortunately, there was poor seeing on all of the nights when I was doing this project.  Your image looks so much sharper!

Thanks Ron. After cold front, some clear nights with good seeing are possible here. smile.gif
