Alex,
Finally back in Terra Australis after 7 weeks abroad
Great to be back in the best country in the world
You have captured an excellent M16 there and have exposed some really nice detail around the pillars
Colour looks good too !!
Well done indeed !!
A few questions if I may -
In Startools , did you load your Mono data set via Compose and select “Linear” ? If not, this maybe the reason why you have to back off the Green Bias so much. Using my OSC 2600MC I usually have to back off the Green Bias significantly due to the OSC matrix having RGGB.
In regard to using “Drizzle” to improve resolution, your Askar 130 at native focal length is 1000mm ( correct me if I’m wrong ) So using either your 2600MC or 2600MM would result in a pixel or image scale of 0.77 arc sec per pixel which is Oversampled. Drizzle only benefits from “Undersampled” data or above say 1.5 arc sec per pixel. Using “Drizzle with Oversampled” data just introduces more noise in the image and no improvement in resolution.
Oversampled data greatly benefits from Binning as we all know ( as in Startools)
If you’re using a focal reducer in the Askar 130 resulting in a new reduced focal length of 600mm or less , then Drizzle may help when using the 2600 series cameras.
I did pixel peep and notice some fine grain noise mottle in the image which is typical of using Drizzle on oversampled data ( correct me if I’m wrong )
When I get some time I’ll send you some more info on Startools Colour ( as promised )
Hope the above all makes sense
Best always
Martin
