Eta Carinae Nebula ( NGC 3373 )with the bright unstable star Eta Carinae in the centre of the image. This is still a WIP - I am capturing more data tonight and the processing needs tweaking ... Edit: A quick and dirty adjustment on my ipad ( the original is too green I think ) ............. Original: From Wikipedia ... "Eta Carinae is a highly luminous hypergiant star. Estimates of its mass range from 100 to 150 times the mass of the Sun, and its luminosity is about four million times that of the Sun." This HDR image is constructed from 12 sets of exposures ranging from 1/8 sec ( to capture the bright centre of Eta Carinae ) through to 240 seconds. Total exposure time around 9 hours. 17-19 March 2018 I am surprised at how bright the colours came out; the stretch was performed with multiple applications of "marskedStretch" and that usually results in subdued colours and I have not touched the saturation ( this is just how it came out following the stretch and brightness adjustment with curves ). ps. is it "Eta Carina" or "Eta Carinae" ?
Not sure if this is really worthy, I was very surprised at how clean the data was for 47minutes total doing a focusing/dithering/guiding/sequencing test in SGP 3. It still lacks some focus which I should be able to correct this week or next as I will have the right flattener for the scope. The only downside is it will also be a reducer as I cannot make the minimum distance for the other scope specific flattener that I have that offers no reduction. Anyway, here it is, NGC3372 Eta Carinae in LRGB. http://www.pbase.com/image/167076501 Cheers and clears.
