Milky Way - Moab by Pierre Williot

March 2023 - Milky Way - Moab

About the Image(s)

In 2018, my oldest son and I when on a camping trip to visit several National Parks (USA).
This was our little tent pitched in Moab, just south of Arches National Park. My son was in the tent with the light on under his sleeping back (to tone down the brightness of his light) - This was done with a single exposure.

Equipment: Canon EOS 6D (Astro converted), Sigma Art 14 mm (EF Mount), Tripod
Set-up: ISO 2000, 8 sec, f/1.8
Post-processing in LightRoom (color balance is tricky with an Astro-converted camera!)

HI Pierre, I love your starry night picture featuring the tent! I love Arches, too, and spent several days there last year. I'm amazed that you could get such a clear image of the Milky Way and detail of the mountains behind with an 8-second photo, and really impressed that you could include the tent in single image. It can be really dark there, and I would think it would take much longer to record that much detail. What do you mean by an astro-converted camera: that's a new one for me. Anyway, I think the composition is great!

Hi Kirk, sorry for the delay on answering your questions. Camera conversions:
Basically : 1) the wave frequency that the sensor can pick are far greater than the visual spectrum. The camera manufacturers will normally add 2 filters in front or your sensors - a UV filter and a AA filter.
2) several camera conversions are possible. The most frequent is a UV conversion (several conversions frequencies are available depending on the desired effect) and an Astro-conversion.
3) the Astro- conversion consists in having all the filters removed, leading to a full spectrum sensor. This is a particular conversion frequently used for the night sky. When all the filters are removed, day time photography bring out very unusual tones - normally not done.
4) with an Astro-conversion, I can perform infrared photography by using a UV filter in front of the lens (different filter frequency available).
I can keep going, but this is the essence.
Infrared photography and Astro-photography are quite interesting!

Thanks, Pierre. Appreciate the insights. I obviously need to do more research on astro-conversions if I'm going to try more night photography.   Posted: 03/07/2023 11:08:34

Hi Pierre, I love your image and thank you for the information on a camera conversion for astro, as I had not heard of that as well. The details that you have captured is incredible, milky way, stars, tent and the rock formations. I would have that one on my wall. I am doing an astro workshop next weekend and am so excited to have a go.   Posted: 03/13/2023 02:17:05

Considering the lighting conditions you have done well to capture the detail in the rocks. Good idea having the light in the tent sure adds to the pic. All ways like star shots, good one Pierre.   Posted: 03/23/2023 00:50:58

Hi Pierre, this one of good examples how to shoot milky way. You purposely set your son tent into the scene. Job well done!
