Rosette Nebula HaSHO

[Rodd]

FSQ 106 with .6x reducer and ASI 1600 with 3um Astrodon filters.  Finally added OIII to the mix.  My goal was to do the Rosette in LRGB (or HaLRGB), bur the Moon didn't cooperate.  This is an image completed while I wait for the data for NGC 1333.  After NGC-1333 hits the trees, I have 2.5 hours to shoot this target.  I can honestly say I am sick of the Rosette nebula in the Hubble pallet....this is my 3rd such attempt.  Fortunately they were at various focal lengths.

Conditions varied widely for this data set--especially in the red (SII) data--so its not the best.  

Ha: 63 5min

SII: 54 5min

OIII: 47 5min

Every nice Rodd...  just one question... do you ever have clouds in Connecticut?

Can not fault this image Rodd. Love it.

Is it me or do you notice the slight multi colour ringing around bright stars?

thanks Dave.  Part of this data was shot on a very wild night--in between passing clouds.  I was out there 9 hours and only got 3 hours of data!   A very rough night.

Just one in the central cluster.  I have 2 issues--wildly different FWHM values in the SII data (2x the other data), and a slight spacing issue.  I believe I am 1mm to close.  I have the necessary spacers to move the camera 1mm back--but I wanted to finish a few images first.  Thatswhy the stars are a bit funky with this set up.

That really is the beauty with that camera, cloud dodging. I'm at it tonight with my 071.

I was going to say curse....but I see your point

I am getting sick of seeing the Rosette in this orientation.  I like it much better like this

A bit less bright
