NGC6888 in c/astrophotography@lemmy.world
[–] bistdunarrisch@lemmy.world 2 points 4 weeks ago

Sadly my lens has not perfect back focus, since I‘m using a system camera there is nothing I can change about that. The effect is a little bit compensated with using BlurXTerminator.

The image is cropped a quite a bit, the aspect ratio is still 4:3 however.

I tested Procreate for iPad. I have no prior experience in drawing other than art lessons in school, so I was plesently suprised on how well the image turned out. Of course it was inspired by Bob Ross.

Thank you for your nice comment!

The stripes are called walking noise/ pattern and often show up when not using a tracking mount and not using dithering.

Because not every pixel of your camera captures signal exactly equally bright you‘ll see this difference along the movement of the sky as it gets accumulated with every subframe. The only way to get rid of it is to vary the pixels for each part of the image after each exposure. This can be done by moving the camera slightly after each shot. This process is called dithering.

With good calibration frames the pattern can by minimized very slightly. Other than that the only real option for processing I can think of is to hide the pattern by not stretching the dark ares too much.

Other than that great image!

Ich gehöre seit heute auch dazu. War ein langer Kampf, letztendlich hat alleinig die Gesetzesänderung zur Durchsetzung geführt.

I didn't check but would guess right about one hour. Plus ~30min registration. Normally I just start the process and leave my laptop and come back later, so I don't know for sure.

Heart and Soul nebula (infosec.pub)
 

On our journey to shot the best images we can with our non ideal setup we collected more data on the heart nebula. Main problem with our setup is the distance of the sensor which is not perfect and results in bad star shapes in the corners. Stepping down to 2.8 and using BXT helps a lot. Combined with old data we gathered a total exposure time of 14 hours.

Editing:

  • stacked, remove green noise, BGE in Siril

Shoot with a Samyang 135mm lens and a Fuji X-T5.

NGC 7293 - Helix Nebula (infosec.pub)
 

This is a first test to shoot NGC 7293 with a 135mm lens. Sadly we could only gather 15 min exposure time as the time frame for shooting this nebula is super short and we had a lot of clouds. Hopefully we have better conditions next year. But this test makes us hopeful to get a decent image with our equipment.

Automatic watering system for my strawberries (infosec.pub)

As I don‘t have a water outlet on my balcony I use a water tank and a pump for watering my strawberries. I developed a controller for the pump which runs natively on Apple Homekit but I‘d like to change it to Matter and Threads in the future.
