Using Startools

[muletopia (Chris)]

I really am lost. I can not get colour from a stack of demosaiced images with Startools 1.5. Before I overwrote my Startools 1.4 , Using Startools 1.4 the stack gave a coloured image which nedulosity could clean up. This excursion was needed to use the white balance in Startools for images from my new QHY one shot colour camera.
I am sure that Startools 1.5 mustbe able to show colours but I surely don't know how.




Last year I used my Canon and produced an image.
So I hope someone can tellmr hoto use ST 1.5.


Attached are three images , last year, ST1.4/Nebulosty ST1.5

Stacked data ( data set ) for both Startools v1.4 and V1.5 should be unstretched, not white balanced , or colour calibrated just raw linear data from the stacked image in fits format
In Startools V1.5 choose Linear ( left hand side tab ) as your type of data

I use a DSLR obviously with Bayered Matrix and not white balanced or colour calibrated from Deep Sky Stacker and “Linear” works fine

Hope the above helps ?

If you use the second option to import your stack, luminance is processed separately (but simultaneously!) to your colouring (the Compose button will be lit green ). This means you are working mostly on the detail (luminance) until you hit the Color module where the final composite is made and youi'll see colour.


You will also be asked to check your coloring in the Wipe module (it now wipes two datasets in parallel).


For DSLRs and OSCs where no whitebalancing has been applpied, this gives a small boost to signal quality.

This behaviour is really a shortcut for launching the Compose module, loading the individual channels, doubling the green exposure vs blue and red and selecting for L + Synthetic L form RGB, RGB for the "L, RGB" parameter. The reason for the green exposure doubling is that a DSLR or OSC with a Bayer matrix has two green samples per 2x2 patch, versus just one sample for red and one for blue.

Be sure also to check out 1.6 which is stable and close to release. It comes with a heap of new features, optimisations and other goodies.


Hope this helps & wishing you clear skies!


EDIT: also, if you'd like some help processing one of your stacks, let me know!
