Hi Paul,
Appreciate your thoughts - yes I am not aware of any software that helps you determine optimal sub lengths per target and filter combination.
My allocate time in 30 minute blocks was just to make it far simpler when I want to switch targets imaging on two scopes if every target's plan is just a variation of a group of subs totalling 30 minutes per cycle - it makes target swapping simpler.
So give I have about 75 targets I wish to image - you guessed it I have 150 imaging plans and all look cohesively similar - so I would guess its likely not optimially set up.
I am rather curious by of your technique comment "One length giving around 1000 saturated pixels per sub" - how do you measure it and why do you choose it?
I presume you are saying in a camera with maybe 20 million pixels you desire around 1,000 pixels to have a full light well - do I have that correct?
Very interesting proposition - so only a fraction of total pixels - and those for the bright points in your subs are totally exposed - but how do you measure it?
I use APT and SGP to control imaging - and perform a low stretch on my subs when they are displayed.
So if I look at a 300 second shot of NGC 300 through my 132mm refractor into a ZWO blue filter into a 1600MM-c I see the following histogram - stretched which doesn't look like many pixels are at all near saturation - must check if I am reading that correctly!
What are you using to determine how many pixels are saturated - Voyager again?
Thanks,
Matthew
