Rosette Neb Ha and Ha SII OIII

Hi All

These are Ha 45min SII 1.5hr OIII 1.5 hr exposures

Mapped as Red - SII; Green - Ha; Blue - OIII
Processed with Fits Liberator, CCDSoft and photoshop

Growing realisation that Narrowband Imaging needs seriously long exposure times.

Also noticed Field Rotation developing in lower right of image

However, does not necessarily need dark skies for success

Thanks for looking
