First image with my new Star adventurer GTI tracker
Image of the Monkeyhead nebula I took last night.
Equipment:
- Lumix G85
- Lumix 100-300 f4-f5.6
- Sky watcher Star adventurer GTI Image:
~ 1.95 hours of exposure
- 100mm zoom (200mm ff. eq.)
- 30 sec, f/5, 1600 ISO
- 233 Lights
- 50 Biases, Darks, Flats
Stacked and using Siril with Starnet++
With the new mount Im seeing a lot less walking noise compared to the old one (Omegon Mount MiniTrack LX3 Essentials) and its a hole lot easier to get setup because of the easy polar alignment and goto.
Can anyone explain to me the horizontal stripe of noise at the top of the image? Its only red/yellowish noise and only there. Part of it might still be nebula, but especially to the left is a lot of noise. There are more stripes like this all over the image when bumping up the contrast and saturation. Some of them are more green and blue and some like this.

That stripe might be some glare/light leak. Does it show up in any of your calibration frame stacks if you crank up the contrast on those?
No, not in the flats and biases. I can see some faint stripes when looking through the lights with the display type changed form linear to histogram. On some images more than on others.
I also noticed that the stars are moving horizontally across the images because the guiding wasn’t spot on. Maybe this is just walking noise?
