SannaLast night I took my camera and went to the lake shore with the hope of seeing some northern lights, since forecast said there is a chance to see them even in southern Finland.

JeffHad my last official aurora tour of the season last night. We got hit by a CME during the day and we weren’t sure if it would hold until night time hit in Alaska. <br> Luckily we were in for a treat, with huge columns and deep red and blue colors covering the sky. <br> <br> It’s been an amazing season, I’ll keep posting up photos here and there but it’s time to relax with friends and family for a while. <br> <br> <a href="https://pixelfed.social/discover/tags/auroraborealis?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#auroraborealis</a> <a href="https://pixelfed.social/discover/tags/northernlights?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#northernlights</a> <a href="https://pixelfed.social/discover/tags/aurora?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#aurora</a> <a href="https://pixelfed.social/discover/tags/astrophotography?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#astrophotography</a> <a href="https://pixelfed.social/discover/tags/nightsky?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#nightsky</a> <a href="https://pixelfed.social/discover/tags/sun?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#sun</a> <a href="https://pixelfed.social/discover/tags/stars?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#stars</a> <a href="https://pixelfed.social/discover/tags/naturewonder?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#naturewonder</a> <a href="https://pixelfed.social/discover/tags/beautifulworld?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#beautifulworld</a>
In my off season this past fall, I decided to go to Kauai and go backpacking all over the island. Coming from Alaska it was quite pleasant to wear shorts constantly and have good fresh fruit everywhere you went. While I was camping on the west side of the island I decided to pull the camera out and get some Milky Way shots. What I totally forgot about was the #comet C/2023 A3 passing by our planet.

The hooting and hollering that I made when I first looked at the image could be heard for miles.

The upper part of the cloud is lit up from the moon rising behind the island creating a very pleasing image.
I am shooting this on a #sony A7iii with a 20mm f1.8 lens. 30” exposure, iso 1250

Some incredibly vibrant views from my driveway. While on the previous post we were talking about the greens and purples of the Aurora, in that last photo there is a huge curtain of red above the green arc.

Both these are caused by atmospheric oxygen, but the reds are from oxygen that is higher in the atmosphere. When these gases get hit by the charged particles from the solar wind, they vibrate to expel the positive charge and return to a neutral state. Depending on the amount density of the gasses (lower in the atmosphere has more, higher less) the vibration has a different wavelength that our eyes perceive as light. So reds are happening about 200km in the air with the greens happening about 100km up.
The reds can be somewhat difficult to see with your naked eye but in instances like the second photo they are very vivid to the earthly observer.

19/03/2025 - Cold night on the hill. We took the scope with us on our evening walk. The sky was clear but slightly hazy. Tonight's photo is of the flaming star nebula. Whilst waiting (photo took about 2hrs) the aurora popped by to say hello. Quick snap with my camera (bit wobbly as I didn't have my tripod), it didn't last long but it was nice.

I had a lot of folks show me the photos they took of the moon on their phones from last night. Phones are getting better each year, but my Sony A7r V shows there still isn't a replacement yet for an SLR/DSLR, a good lens, and a little bit of knowledge. Exposure bracketing made this one of the best moon photos I have ever taken.
