Perseids Meteor Shower (and other)

Missed the high point of the Perseids on Aug 12th but got a reasonable showing this morning (1:30-~2:30am).

I shot 219x20sec. subs with a Samsung 14mm lens at f/4 on a Sony A7 III @ ISO 21800 mounted on a Sky-Watcher Star Adventurer 2i EQ mount.

About 22 of the 219 subs showed indications of a meteor, almost all of the subs shows satellites, airplanes or other garbage; the sky is getting very cluttered!!

The first image is a cropped region showing a few meters. Aligned in PixInsight and Max. Combined in ImagesPlus.
The second image shows an airplane track. Aligned in PixInsight and Max. Combined in ImagesPlus.
Be sure to hit the 'Download' to get a zoomed view.

The last image is simply all 219 subs stacked and postprocessed to show the Milk Way. Aligned in PixInsight and Min-Max. Combined in ImagesPlus.

Enjoy!

Beautiful shots Brian!
Glad you gathered some up. I happened to have clouds, so passed.
I didn't think you had Airplane nuisances up there. LOL

I'm trying to figure out how to make pictures with my new mono camera. I've got lots of B&W through filters, just can't figure out how to do the color yet. LOL

Nice shots. Between the smoke and high clouds nothing to see at night around here right now.

LRGB processing is a science / art form unto its own. I use the LRGB Combine in PixInsight; however, you can actually do it in Photoshop (so I'm told). You just assign those greyscale images to a color and stack them all together... It is truly the only part of astrophotography where you can let your imagination run wild with color!

I'll try that approach.
I half-heartedly have been watching videos. But they always veer off into this or that program the author prefers.
I have Photoshop Elements 12. Fairly ancient now.

But I'll try assigning the color to the filtered images.

ASI ZWO has a good DSO imaging program that collects and saves the images into a file in a file folder I select.
So the images are individual for picking.
I just haven't figured out whither to or how to color them before stacking, or after, and how to accomplish it.
Dawdling along.

In Photoshop you can split a color image to the Red, Green and Blue (RGB) channels and end up with three greyscale images. Color processing narrowband images is the exact reverse of this. Assign your greyscale images to a color channel and press the Go button.

The example below is from PixInsight showing the four greyscale images on the left and three LRGB 'attempts' (using various Channel Weights) on the right. As I said previously, LRGB processing is an art form...

Enjoy!
