Last night narrow band S11 HA O111 35m 20m 35min stl-11000m on a NP 101mm F/5.4 i will post onother later as i have to go out this has been rushed. Has been croped. The compression has stuffed it a little.
Nice work Phil. What are you narrow band filter mappings? Are they "SHO" (hubble style) or HOS?
SHO = R: SI G: Ha B: OIII
HOS = R: Ha G: OIII B: SII
HOS gives a more natural view, but depends on the object being framed.
What is absent from your information is exposure lengths per channel... would you mind telling us (including the subs). I'm expecting something in the order of a few hours at least.
Note the STL 11k is very senstive in the green spectrum, hence your image isn't weighted very well. Just lower you exposure duration for that filter or within photoshop add an adjustment layer for that channel, then modify the hue/saturation settings.
The data was red s11 green ha blue o111 the exposures where only 35min 20min 35min one exposure pure channel. The green channel was the strongest channel. This was just a very quick RGB merge as i had to go out the final image will be very different from this as i was only stuffing around with the colours. I will be getting more exposure data over the next couple of nights. this i only the beging of the data collection of this image.
Sounds good Phil. Thanks for the additional info. Looking forward to seeing the result once you gather more data. Just with the data you've got now, have you tried HOS within PS. Would be interesting to compare the differences from an asthetic appeal.
