Caldwell 49 - Rosette Nebula - Hubble Palette Narrowband

Rosette Nebula / Caldwell 49 - Narrowband Hubble Palette

 

This is a progression from my previous Narrowband session on the Rosette Nebula (www.flickr.com/photos/30345959@N08/13181515933/), I have gone from 7x600S Frames to 16x600S frames and what a difference it made

 

Object: Rosette Nebula

Location: Moneceros

 

Image Details:

7nm HA Data: 16x600S

7nm OIII Data: 16x600S

7nm SII Data: 16x600S

Darks: 23 Frames

Flats: 23 Frames

 

Equipment used:

Imaging Scope: Celestron C80ED APO Refractor

Imaging Camera: ATIK 383L+ Mono CCD Cooled to -25C

Starlight Xpress 7x36mm EFW

Guide Camera: QHY5 and now QHY5L-II

Off Axis Guider: TS 9mm OAG

Mount: Skywatcher NEQ6Pro (Steel Pier Mounted)

I went through the same technique of adding a HA layer as Luminosity after finalising the colours
