M42 IDSSP Stack 2frames 32s
Last image taken at the IDSSP over the weekend. Clouds were coming in so M42 is not centered in the view, but this image was taken in 32 seconds. I thought these were 15 second subs, guess my seeing was bad ... 16 second subs. That's what happens in the middle of the morning when eveyone else in the observing field were sleeping away. Skies were dark, but clouds were nearby and coming in fast.
Compare this to M42 taken a few minutes earlier and longer stacking. This image has surprising detail.
