I didn't do anything special with the printing. The filament is 3DQF PLA, and I printed it with 4 perimeters and 10% cubic infill. Whether it holds up to our weather or not remains to be seen! I believe @Chriske has used prints outdoors, and somewhere in the forum threads I think there are a few others, so there should be some opinions on long term outdoor use. As these are under compression they might be ok.

They've managed to get a final photo of Ingenuity from Perseverance and it's definitely lost a blade. The missing one is sitting about 15 metres away. https://arstechnica.com/space/2024/02/final-images-of-ingenuity-reveal-an-entire-blade-broke-off-the-helicopter/

Thanks. The intention is that these would be safe against lawnmowers, but I have no idea if they actually are yet. They're 75mm long, and didn't go into the soggy clay soil here that readily, so might be ok. They're pushed in level with the surface.

Mognet started following What do you drink while stargazing? and Ground spikes for tripod positioning

After experimenting with some plant pots laid out in a triangle to help with positioning the tripod I've 3D printed some ground spikes that should hopefully be better while also not being trip hazards. The soft ground from the recent rain helped greatly in pushing them in. This could be one of my saner ideas. Just need a clear night to try it out. The STL for it is attached. TripodPeg.stl

Hot chocolate, especially on cold nights at the eyepiece. If I'm indoors keeping an eye on an imaging session then it varies. After 9pm it's usually decaf coffee or peppermint tea.

Seems like Ingenuity was quite impressive given how it was made. Nothing was space hardened, it was all off the shelf parts and made to a weight limit of just 4 pounds! https://arstechnica.com/space/2024/01/now-that-weve-flown-on-mars-what-comes-next-in-aerial-planetary-exploration/

ZWO/Player One IMX 585 Sensor Image Showcase
Mognet replied to Chris's topic in Discussions - Cameras
Taken last night in less than ideal circumstances; full moon, thin cloud, focus slightly soft, and light pollution in that direction. And I still managed to pull something from it. 81 subs of 60 seconds at gain 252, stacked in ASTAP and roughly processed in GIMP -
For what was only meant to be a short term experimental aircraft it was quite amazing, especially as it was being flown on another world in preprogrammed flights. The last planned flight was for a greater distance than the Wright Flyer ever managed https://arstechnica.com/space/2024/01/nasas-mars-helicopter-has-made-its-last-flight-above-the-red-planet/ https://en.wikipedia.org/wiki/Wright_Flyer

I guess if you're sitting on the sofa and throwing them at any visible spiders then they're likely to work! 🤣

Starlink pass 18th January 2024
Mognet replied to lukebl's topic in Imaging - Widefield, Special Events and Comets
For Starlink they've needed the approval of the US Federal Communications Commission (https://www.space.com/spacex-fcc-approval-7500-starlink-satellites) I've not seen anything that covers worldwide approval for launches so maybe there isn't anything in place, although with current geopolitics countries could block each other from launching satellites if there were. -
That's great. Never realised there was so much dust in that area too.

My brother bought me a furry hat to wear when I'm out. Haven't actually done so as I have a large head (but no brains) so it barely fits
-
Mine last night was telling me what I already knew - it was cold! I assume it's actually there as an indication of acclimatisation

I'm testing an update that handles the new versions of Raspberry OS and the v3 camera, and can hopefully sort out some code that will handle the older cameras with no additional user intervention. In the meantime I'm trying to find the source of an intermittent bug that causes the generation of a new video to fail leading to a 404 error when trying to view the video. If you can't wait until then, the test code, which uses libcamera-still instead of raspistill, is in the update_for_v3camera branch on GitHub.

SGL 2023 Challenge 9 - The Earth and the Moon
Mognet replied to MartinB's topic in SGL Challenges and Competitions
From the RHS Glow at Hyde Hall event. Taken Friday 25th November, and has a bonus Jupiter with the moon. Handheld shot on a Nikon D3400, 18-55mm kit lens at ISO3200. Minimal processing in FastStone Image Viewer.
