Orion Nebula

[Granada]

Equipment: EQ6-R, SW 150ED Evostar, Canon EOS 80D, 0.85x focal reducer
Exposure time: 15s
ISO: 200
Stacked: 25 in DSS, used about 20 dark and flat calibration frames (but I'm pretty sure the flats were no good because I didn't check the histogram to ensure it's in the centre)
Just some minor stretching, colour adjustments and brightness/contrast adjustments in GIMP.

Would be keen to hear some constructive feedback and ways to improve. Cheers

That's pretty much spot on. :thumbsup: I have nothing to add that would help you. :lol:

I agree with Marc. You've done really well, especially given the 15s exposure in Melbourne: the core is nicely exposed with good greenish/blue colour, surrounded by pink/redish colour is not overblown and shows the trapezium stars distinctly and your 25 exposures have cleaned up the noise.

My only comment is, if you want to see more of the nebula then you could try longer exposures melded with your current shorter 15s exposures using layer masks in Photoshop (Gimp?) to pickup more faint detail in the outer parts of the nebula from the longer exposures whilst not overexposing the core since you could use your current shorter exposures for that...... If you want to. It's good as it is.
