Great Nebula in Carina in H alpha and OIII

[MLParkinson (Murray)]

I built this image of the Great Nebula in Carina back in February 2018 using data recorded during April 2017. It can take a long time for me to process data. Like most people, I go flat out at work all week. I hope that you like the image anyway. Technical Details: Two-panel mosaic built from many hours of exposures recorded using a Televue NP127is Refractor @ f/4.2, Astronomik 12-nm H alpha and OIII filters, and a QSI683wsg scientific camera.

Beautiful shot Murray. Plenty of detail!

Nice to see such a big FOV, Murray!

Sorry.... don't like the Swedish Flag colour scheme at all.

Peter: You produce some beautiful photographs. Your use of traditional colour palettes is very effective. Kind regards, Murray

Thats great! What sort of integration time is that pic, i wonder?

[MLParkinson (Murray)]

I am fortunate enough to have a backyard observatory which I control remotely from my rumpus room. This means that I can capture very long sequences over multiple nights without too much stress.

Hydrogen alpha: 87 frames x 14 minute exposures = 20 hours.

Oxygen III: 48 frames x 14 minute exposures = 11 hours.

Don't take it to heart...I'm not a fan of those meatballs in Ikea either

There's good detail there Murray but to me it's overshadowed by the garish colour palette you have used.

May I respectfully suggest considering the following -

I don't understand what you're saying Andy. According to both of the articles you cited, the colour scheme I used for my latest Eta Carina image is a recommended complementary colour scheme. In fact, the colour scheme I used is the number #1 recommended colour scheme given in both articles. And it also follows that the red-blue colour scheme favoured by most astro-photographers are not complementary. Are you suggesting that I should abandon colour theory? That is, you are citing the article because you think they both provide bad advice? Correct?

Sorry Murray, but I respectfully disagree, your colour scheme is cyan/yellow.
These colours are only separated by a few steps on the colour wheel.

Complimentary colours are usually opposite one another.

ie: If you favour cyan for the centre of your image, an orange would sit better then yellow

Of course there are no "Rules" as such in NB imaging, but basic colour theory can be helpful when determining one's selections of colour palette.

Hey Murray, looking past the colors which is a personal preference, your stars are burnt on the high resolution but the details you've got are very good. So I reckon if you do a repro and watch out for white clipping with your stars you'll have a corker and one for the cool wall.
