Eta Stl-11000m Narrow Band

[Phil]

Taken over two nights 2x20mins each channel 0111 HA S11 STL-11000M on G11 mount . Telescope NP101mm F/5.4
Thanks for looking
Phil
The high res is 50x better.:thumbsup:

Would love to see the full rez Phil.

The image does look some what clipped with plenty of nebula missing but this would increase with more exposure.

Looks great....lets see the full version.

Nice work Phil. I'd be interested in seeing a large version.

Interesting use of filters. Normally people map the colors to HOS or SHO, but you've done OHS. No rules, but interesting. I think you're a little too green in balance bearing in mind that the KAI-11000 chip is most sensitive at in this wave length. Perhaps start with a 1.5:1.0:1.5 (R:G:B or Ha:OIII:SII) ratio and work from there.

Not certain of the filters you are using. The astrodons make life easier by allowing same exposure time for all filters. The way they achieve this is through wavelength crosstalk. For example the G filter also allows a lot of the blue wavelengths through. The downside to this is contrast, as each filter is quite broad in what they transmit.
