NGC 2070 - Tarantula in Narrowband - HST Palette

Hi All,

I acquired some more Ha data and some SII data for the Tarantula.

I added them together using the Hubble palette, LRGB mapped to Ha:SII:Ha:OIII.

I reduced the star halos which I typically get when combining the data this way and tweaked and tweaked it in PS.

Although this is probably not the last version of this object, I like it the way it is.

Taken with my 8" RC, SBIG ST-10XME, over two nights (2&3/12/2009).
Ha is a combination of 120 minutes through a 4.5nm filter and 100 minutes through a 13nm filter. OIII is 60 minutes through a 13nm filter and SII 60 minutes through a 13nm filter, binned 2x2. All sub-exposures were 10 minutes.

Cheers
Stuart
