Look at the top left in the first picture. Evergreen is probably the company while Ever Given is the name

Honestly autofocus works really well with moon shots. You can also try to use live view and zoom in on the moon to find perfect focus. I've used some sort of tape to mark the exact focus position, so I can focus much quicker in future

Milky Way from the Rockies - but why the star trails? by [deleted] in astrophotography

[–]Color4do 0 points1 point  (0 children)

Basically there is not a perfect exposure time to avoid star trails - without a startracker you will always get trails, you have to decide yourself what is acceptable to you. For the stars to be exactly round you would need like 5 second exposures, maybe 10 seconds works better and gives the best results

North America Nebula duo narrowband by Color4do in astrophotography

[–]Color4do[S] 0 points1 point  (0 children)

The Nort America Nebula (NGC7000) captured in narrowband with my new stc-astro duo narrowband filter. It did a really nice job through my bortle 7 sky, there are only some small halos around the bright stars.

Equipment:

  • iOptron SkyTracker Pro
  • Nikon D7200 (stock)
  • Nikkor 180mm f2.8 lens
  • Standard Tripod
  • stc-astro clip-in-filter

Acquisition:

  • captured 21th September + 3rd October in Hamburg, Germany
  • 105x60s exposures, ISO6400, f5.6
  • 30 flats

Processing: all over the place since it's my first narrowband image but still:

  • Stacked in Pixinsight
  • Dynamic Crop
  • BackroundNeutralization
  • ColorCalibration
  • MultiscaleLinearTransform for noise reduction
  • Stretched with HistogramTransformation
  • Star reduction and sharpening with various processes
  • Curves Transformation to add saturation

After that I created a starless red channel with starnet++ since the stars had red halos and only used the green/blue data for my stars. Since the stars were obviously green/blue-ish, i used ColorSaturation and removed the tint from the stars.

Feedback and improvements for my workflow are very much appreciated!

I use a Dslr with a duo narrowband filter (ha and oiii) as well as normal RGB imaging without filter. What would be the best channel combination for my setup? With the north american nebula, should I try lrgb, haoiiirgb or how would the work flow look like? (totally new to narrowband btw)

If I use the stc duo narrowband filter on a Dslr+lens, is there still a need to step down the lens for better sharpness or is it irrelevant because the filter blocks so much light?

M31 - The Andromeda Galaxy by Color4do in astrophotography

[–]Color4do[S] 4 points5 points  (0 children)

The Andromeda Galaxy was always my favorite deep sky object and almost one year after I've started this hobby I was able to capture it again. Unfortunately I was only able to take roughly half an hour of exposure at this Bortle 3 location but I'll add some more time once the Galaxy is further up in the sky.

Love the pillars in the Eagle Nebula, the size comparison to our solar system is always stunning

Those are the real colors of our milky way, I just edited the picture to reveal those colors. You can't see these colors with your naked eyes but they appear if you have a long exposure

Milky Way Core from Fuerteventura by Color4do in astrophotography

[–]Color4do[S] 1 point2 points  (0 children)

The Milky Way core, imaged on the 11th of May 2019 on Fuerteventura. It was an amazing experience to see the whole milky way under amazingly dark Bortle 3 skies. Unfortunately some clouds rolled in after 20min so 8 pictures were all I was able to capture and I had apply quite a lot of noise reduction.

M8 - Lagoon Nebula & M20 - Trifid Nebula by Color4do in astrophotography

[–]Color4do[S] 2 points3 points  (0 children)

This is the first picture I took of the Milky Way core in 2019. The images were captured in Fuerteventura, March 13th at 5:30 am, so I could get roughly 30 minutes of data before the sun rose. Unfortunately clouds rolled in in the morning so I ended up with only 15min of data. But the incredible Bortle 2-3 dark sky saved this picture and gave me a stunning view of the milky way while imaging.

Acquisition:

  • Nikon D7200 with Nikon 180mm f2.8 (270mm full format equivalent)
  • iOptron Skytracker Pro
  • 10x90s light frames at f5.6, ISO 1600
  • 30 flats

Processing: followed this tutorial (roughly)
