Brian,

 

Being that they asked is probably a good thing. I don’t think they pay for images so if it is used you might not know until you get the white envelope with a couple of early copies of the magazine.

I sent my CA neb to S&T and the editor asked for a higher-resolution version.  He must not have liked what he saw, cuz I heard crickets after.

Berkeley 11 is a trumpler (https://en.wikipedia.org/wiki/Trumpler_classification) class II 3 m open cluster located approximately 9,400 light-years away in Perseus.

 

While barely there, Sharpless 213 is a small, faint nebula just to the left (east) of the cluster.

 

Luminance – 12x300s – binned 1x1 – 60 minutes

RGB – 8x180s – 24 minutes each – binned 2x2

 

132 minutes total exposure – 2 hours 12 minutes

 

Imaged January 21st and 22nd, 2018 from Dark Sky New Mexico at Rancho Hidalgo (Animas, New Mexico) with a SBIG STF-8300M on an Astro-Tech AT12RCT at f/8 2432mm.

Should just be an exe without any kind of install. Here’s what I have. Just unzip it and open a command and run:

 

Ffmpeg –i <inputfile.avi> outfile.mp4

If you want to keep videos, ffmpeg can convert for you if you want to deal with the command line.

 

https://ffmpeg.org/

 

I think the command is ffmpeg –i infile.avi outfile.mp4

 

If you’re just looking for the picture, I’d recommend just running them through ASI2/Astrosurface/etc on the PC there and then transferring the single (or multiple if you do multiple % stacks) images…

I’ve got some cool video showing closeups while panning across the moon.  But they are AVI’s and 2,000Mb apiece.   Downloading via TeamViewer and AnyDesk has failed because they are too monstrous.   So I tried and failed to convert them from AVI to MP4.  My old Win7 machine has Photoshop CS5 so I tried rendering ten times with various settings but it always changes the 960x640px size to 1280x720 (wrong aspect ratio).   Cannot upgrade PS on that machine.

So I tried VLC Media Player to do a simple conversion from AVI to MP4.  But it stops after just one frame.  I downloaded freeware for just converting and it just hung there while trying to convert.

Any advice on how to get these videos home?

Happy Thanksgiving all!

NGC is an interesting open cluster in Perseus - very old and with some blue stragglers:

Hi,

 

This is an image of NGC 1333. It is a reflection nebula about 1,000 light years away in the constellation Perseus. The reflection nebula is the bright blue section in the middle of the image. Just to the left of the reflection nebula you can see bright red emission nebula formed by newly formed stars. NGC 1333 contains over a hundred star that are less than a million years old. Many are hidden from optical telescopes due to the dark nebula seen as the dark patches throughout the image. Some astronomers believe our sun may have formed in a cloud similar to this one over 4.5 billion years ago.

 

Comments and suggestions welcomed.

Luminance – 24x600s – 240 minutes – binned 1x1

RGB – 10x300s – 50 minutes each – binned 2x2

 

390 minutes total exposure – 6 hours 30 minutes

 

Imaged November 15-19, 2020 from Dark Sky New Mexico at Rancho Hidalgo (Animas, New Mexico) with a SBIG STF-8300M on an Astro-Tech AT12RCT at f/8 2432mm.
