A night out with the x-t3

47 light exposures, 20 darks, 20 offset
1 min iso 1600 f/5.6
70-300 nikon zoom @70mm
Deepsky stacker with a touch of curves in ps
Ambient temp about 2°C at 6am

Center of the milky way, Jupiter is brightest object, lagoon nebula in pink to the left of the frame, and slightly above in blue/pink the trifid nebula

I'm sure many more objects can be named among the staggering amount of stars visible in this region of the sky

Well done getting that much of the dust and hydrogen alpha in the nebulae showing up with that exposure, Armando. It must have been a pretty dark site? That part of the Milky Way is below the horizon here now.

hmm, fairly dark, it is certainly at a higher altitude, about 2200m above sea level, but there is small town about 5km down the road, the electric lights are visibile from this site, then the light pollution from Gdl is very evident towards the north, so, it is darker than near Gdl, and only about 1 hr away.

I was interested to try the fuji sensor, I read it is more sensitive to the h-alpha channel, and it certainly seems to be, easily more than D800

here is the lagoon nebula at 300mm
20x 1 min exposures, iso 1600, f5.6
