First time Dithering
Last night whilst imaging the Southern Pinwheel Galaxy I tried dithering for the very first time
I was Dithering each 4 minute sub using BYEOS and PHD2 ( Spiral )
I found each Dither to be different , some would be quick with little affect on guiding whilst others would kick the guiding around pretty severe
I was guiding around 1 arc sec
It it normal to have dithers that do almost nothing and others that shake up your guiding pretty bad eg 1 arc sec up to 1.9 arc sec
I noticed after a big Dither the guiding took almost 2 minutes to calm down to something close to where it was prior but not to the same level
My settings in BYEOS were -
Dither Aggressiveness was 2 or low
Settle Dither was 0.35 for average guiding
Calm down was 20 seconds which didn’t do anything on the big dithers as they took 2 minutes
Appreciate any advice or whether the above is normal for dithering
Cheers
