p.1 #1 · p.1 #1 · Milky Way shot, feedback?


Aloha, first time posting an image here.

It seems like so much of processing astro is ‘to taste’, but then again i know things are supposed to be certain colors, etc. I’ve been reading up on it all for days but it’s a lot to digest. Thoughts on the processing of this one? Shot from Haleakala on Maui looking across at the Big Island. The orange is from the lava flow, and I believe(?) much of the low sky color is from vog. Quarter moon was setting behind me.

A7rIII, 16-35
Stars: (12) images stacked, 15s @ f2.8, ISO 1600.
Foreground: (4) images stacked. 30s @ f2.8, ISO 1600.

Minimal adjustments in LR
Stars stacked in Starry Landscape Stacker
Stars edited in LR
Foreground stacked in PS
Foreground edited in LR
Combined in PS

My ultimate goal is a very clean 8’ print, with naturally lit looking foregrounds. Will be moving into panos with the 50 1.4, but starting here with a single stack to get the hang of it first.

Some questions for the experts:

I picked up a tracker, I assume longer exposures with tracking will reduce snr and result in less noise?

How many images do you tend to use in a stack for minimal/eliminated noise?

I tried processing a pano (114 images iirc, 4 rows of 6 plus foreground exposures) and between all the stacking and etc I hit the 4gb ps file size cap. Any tips to control file size but keep ultimate quality?

Any techniques or tips on reducing/eliminating noise or pulling out more accurate color?

Thanks so much!

Lyle

Well I don't hold myself out as an expert, but I think your effort is magnificent. Thus I can not offer any CC.

Stunning work! Way to good not to show it in it's full glory!

Imgur has a bbs code string for including the image url in a post. I can't show you the text here because the software keeps trying to interpret it despite how many ways I try to quote it...

Thanks, I think I’ve got it sorted thanks to some help in pm’s. Appreciate it!

Not clear why you had to merge a foreground with a sky image. You did a great job processing the sky. I find the ground beneath the sky behind the foreground a bit distracting, however. With the both the sky & the foreground in focus, it sort of begs the question, “Why isn’t the ground beneath the sky in focus?” To me, it looks like exactly what it is, two images merged.

I recently processed a MW image using Starry Landscape Stacker and found the foreground looked fine without a separate foreground image/layer. You might try that. I suspect a more natural result will occur.

Superb image. Even without the night sky it looks good. Excellent work.

Hmm. The area between the foreground and the sky is clouds and ocean. Not sure how to treat it differently, I did bring it down with a gradient when processing the stars to make it darker, perhaps that is throwing it off? I didn’t change focus at all, and I swapped the foreground to get better detail and brightness without generating more noise by using the 15s exposure. Thanks for the feedback!

Nicely done! The cloud layer and water did through me off a bit, but once I realized what I was seeing it does pull together better.

Beautiful shot(s)!

Here are my thoughts and feedback.

#1, you don't need much feedback. Considering all of the work, technique, and tools you put into this image, you know a lot more than almost anyone that will post here.

#2, If i must nitpick, the black sky portion of the image dosn't transition well into the light blue horizon area. It does not look natural. If you're going for a natural look, the sky won't have a pure black to light blue transition like that.

#3, for prints, you may want to consider trying what I do. Get all of your MW images separate from your ground images. I shoot my land images during sunset and sunrise blue hours, (don't want shadows). Then I throw my MW images on top of those. With this technique, my MW images are roughly 95-100% sky only. My ground images are roughly 90% land and about 10% of the top image has some sky. This gives you a lot of cropping options once the blend is completed.

#4, I too use a tracker. I usually stack 15-20 images shot at F/2.0 to F/2.8 for 2-4 minutes at ISO 800 or 1600. The editing latitude you get once the median stack is done is awesome! Plus you get rid of any airplane trails too. Auto-Align layers in Photoshop is always accurate because, for the most part, the stars are already aligned in camera.

#5, if you're going to stack 20+ images, you may as well just output to .jpg first. Stacking so many images, you don't need RAW files. Once you've stacked that many .jpg files, your output file will be just fine.

Great shot and nice to see the eruption in the bg. I've only used the SLS a couple of times and been pretty surprised at the results. Good stuff. You might want to check the fg of the sky part as there should be plenty of detail in it. Going to 30s and stacking isnt going to do much for your fg. Might as well go to f4 iso 800 and do a few minute exposure (with LENR on). But do think the fg should be fine with the original star stack. Good job timing it with the moon. Rad shot. Post smaller. You just shared a large printable file with the public

Lyle you did a great job on this one. The color are very natural in the Milky Way, and you can even make out faint green air glow on the horizon. I started out in night sky photography over 10 years ago, and I think you are well on your way. This would be a wicked to print =)

If it was me editing, I would probably darken the sky just a hair, maybe by another 5 to 10 points in curves by placing a color dropping on the top of the image.
