That’s fantastic, what’s the technical stuff?
RGB filters, exposure length, telescope size, camera, photoshop, registax? That type of stuff.

Thanks.

Celestron C-11, operating with a 2x barlow at 5600mm focal length;
ZWO ASI120MC camera (colour, so no RGB filters);
Best 10% of 5000 frames, taken at 40 frames per second;
Taken with FireCapture;
Stacked in AutoStakkert;
Processed in Registax and PixInsight.

Nice. Planetary imaging set up. Capturing AVI’s
What do you think about the x2 Barlow? Does it downgraded the image, and do you lighten up with histogram in processing?

Amazonis, mare sirenum, mare Erythraeum, coprates, Southern Hemisphere regions?

The barlow is essential to get decent resolution. I have a 3x barlow, but the 2x is considered the optimum for planetary AP with the C-11. For processing, I ran it through the RGB Align process in Registax to correct for atmospheric dispersion. I then did wavelet processing in PixInsight to sharpen whatever detail I could. Which was not much, since my focus was a bit off. I didn't do much fiddling with the histogram.

I haven't checked a map to see what the features are. Your knowledge of mars-ography is likely better than mine.

Lol nah, my maps are ancient compared to what’s out there these days.. Olympus mons ( which is actually in the bright region (Amazonis) above the darker band in your image, is called nix Olympia on my map, before it was discovered as the solar systems largest volcano.
