Comet 168P

 
"Frozen" comet motion in DSS /deep sky stacker/ .
Not bad !  :)  Roman

Comet 168P- Still , motionless !!!


"Comet staking with motionless stars is very difficult and is close to voodoo that it sometimes works.
 Depends on the SNR/signal to noise ratio/ of the lights /exposures/. Of course high SNR requires long exposures
which means either the stars or comet trail. So it's a combination of comet speed , aperture and focal
 length that determines what the result will be"- Sander DSS.
I tried it but I need "faster" telescope  F-3 or F-4. Like you se all colour data is lost. Roman
No problem in grayscale  : )
