Sh2-170 - The Little Rosette Nebula

#1

Post by cmassa »

I imaged this in October 2018. Finally processed it and it was tough. Lots of noise, especially in the OIII and the OIII signal was pretty low. Lately I've been trying to learn processing of the nebula and stars separately and it's tough to make the stars not look they were just pasted back in. But, these are narrowband stars and not RBG stars so I'm happy that there is some color to them besides magenta or white!

Total of 39.7 hours of 20 min subs in SII, HA, OIII. Processed in Pixinsight.

OTA: TPO 10" f/4 Newtonian
Mount: Paramount MX+
Camera: Atik 383L+ mono
Filters: Astrodon 5nm SII, 5nm Ha, 3nm OIII
Automation: SGP

Thanks for looking,
Chris

Chris,

Beautiful rendition. I really like Narrowband images. Almost 40 hours of data is amazing. It looks like your dedication to processing is paying off.

Röslein, Röslein, a very beautiful Röslein auf der Heide (of the starry night)!

Lyrics from Goethe (but not the starry night), music from Schubert, and the excellent capture from you.

Hi Marius - Not sure i've seen this one before. Your NB image really brings out the structure beautifully. A well deserved "Picture of the Day".
