Nice, colors, Tristan.

Thanks Borodog, I completely forgot

Anyone (Liam?) know why LiamMcD71's SER files are quite so massive?

 

AutoStakkert claims 8-bit, 800x600 and Jupiter is about 32k frames. Yet the resulting SER is over 14GB?

 

I did try playing with it, but couldn't get even close to a good color balance and the histogram looks "weird".

Grant,

 

That is the proper size for an 800 x 600 x 32,000 frame 8 bit (1 byte) SER file:

 

800 x 600 x 32,000 / 1024^3 = 14.3

Hi RedLionNJ

I don't know either, that's just as they are output from the camera.

 

I actually deleted those files (and the setting files) last night as while I was imaging, as I started to run out of disk space!  But I have one I took last night that is similar (8bit. 800x600, 32k frames - and also about 14GB).  I will put it in the other thread for you too.

Meanwhile, here are the settings from SharpCap for it (should be similar to the other one).

I will put it in the other thread for you too.

 

Please start a separate thread.

Grant,

 

That is the proper size for an 800 x 600 x 32,000 frame 8 bit (1 byte) SER file:

 

800 x 600 x 32,000 / 1024^3 = 14.3

Darn it - you'd be right - can't argue with the math!

 

I guess I'm not used to capturing with such a wide ROI, so the 14.3GB just looked like a huge size to me. I was wrong.

 

Liam - if your tracking is good enough, you should be able to use a much smaller ROI (maybe 300 x 300 on Jupiter) and get a faster fps and a much smaller filesize - leading in turn to significantly faster align/stacking in AutoStakkert.
