Description

My first three filter narrowband picture ever.

I did not have much time for this night after the lockdown period and it was my first opportunity to shoot again after nine months. Therefore I took a quite brilliant target. I am not a fan of classic SHO Hubble palette even if some are very beautiful. So I decided to give it a try with HSO, which preserves the dominant red colour of the nebulae, OIII is anyway weak in this region even if it renders some parts purple. I did not mix anything, H is red, SII is green, OIII is blue.

I took 300s subs only to avoid too much saturation of Sadr.

Hope you can enjoy the unusal colour palette.
