Rosette Neb Ha and Ha SII OIII

[Rob Hamlin]

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

Nice colors given the short integration time. What scope did you use?

Hi Rob, Good to see you posting. What equipment did you use? Mike.

Alas, that's true :) Nice job for a quickie.

Hi Marc

Thanks for you comment.

Scope is a Tak Fs102 @ f6.

Fair amount of stretching in photoshop to retrieve detail from the subs!

Cheers

Hi Rick

trying to get my NEQ6 up to speed for 20min subs..

Think this might be the way forward w Narrowband!

Cheers

Yes, you'll notice a difference. You'll be getting hammered with read noise on short subs.
