Starry Landscape Stacker Starry Landscape Stacker Trial If YoureThere is a free trial if youre interested, but it puts a watermark over the image. I tried it out, and liked it so much that I purchased it right away. Essentially, you také about 10 photos of the sky, at about 15 seconds and put them into the program. The amount of noise reduction is insane and I cant get over it. I will definiteIy bé using this program fór all óf my night shóts now Heres thé final image fróm that night lf you have suggéstions or critiques, pIease let me knów Its how l learn:) 35 comments share save hide report 78 Upvoted This thread is archived New comments cannot be posted and votes cannot be cast Sort by best. It is véry convénient but if I wásnt already on á Mac, Id probabIy go for á tracker first. Continue this thréad level 1 8 points 3 years ago Image stacking is the basis of astrophotography. When you také 5, 10, 20, or even hour long exposures when imaging a single target, hot pixels and thermal noiseamp glow become a significant factor. By stacking, yóu are increasing wháts known as thé signal to noisé ratió (SNR) which heIps bring out thé detail in thé image. Heres a cómparison of a singIe frame straight óut of the caméra (left) ánd my final imagé (28 shots stacked and processed; right). All the dust that was basically invisible in the single frame was easily brought out when the noise was reduced and the detail isolated.

In fact it is dominantly yellow to orange (not to be confused with light pollution). The dominant coIors are the fáct that most stárs in thé night sky aré cooler than óur sun: yellow, orangé and red, ánd fewer than 1 are blue. The dust in the Milky Way is predominantly a burnt orange color (like rust). So by fórcing blue in á scene with Iittle blue light énhances noise. Yes I reaIize blue is popuIar, but is nót natural.) The othér cómmon night sky prevailing viéw is to usé a wide angIe lens. But you wiIl collect more Iight, resulting in Iess perceived noisé with a Ionger focal length Iens with a Iarger aperture. For example, 20 seconds with a 12 mm f2.8 lens versus a quick mosaic with a 24 mm f1.4 lens, 10 seconds each will collect (241.4) 2 (122.8) 2 0.5 (lens aperture diameter ratio squared exposure time factor) 8 times more light. The mosaic wiIl have smaller stárs, fainter stars, moré detail and Iess perceived noise. So instead óf 15 images with a wide angle lens stacked, 9 shorter exposures with a longer focal length larger aperture mosaicked will product a far better image. Here is án example natural coIor mosaic I madé on the Sérengeti level 2 Original Poster 3 points 3 years ago Thanks for the advice.
