Official StarTools support forum

dx_ron The TriRGb filter overall transmission is around 20-25% of my uvir broadband filter, with corresponding increase in exposure times. At F7 i can swamp read noise (RN^2 x10) in bortle 5/6 boundary with 180s exposures with the Altair 26c at gain 100. It has three bandpasses, all about 30-35nm. ...

dx_ron Although I review the forums daily, I very rarely post due to the fact I use STools as only a part (but a very important one) of my overall processing routine, which also uses other software for initial stretching, and finishing work, with STools in the middle. I regularly use Bin,sharpening...

Fantastic!

can’t wait!
Thanks!

Thanks Ivo, thats perfect.
I have always used integer bins in the past, and had excellent results,
But with a new focal reducer I am looking at fractional ones now.
Didn’t want to compromise the quality in any way.
Thanks for the reply.

Just a question Whilst I have contemplating my navel.
In the binning module , what algorithm is used ?
Thx

Thanks Ivo, that helps a lot. I take note of you comment on file size, certainly in the past its a big issue, but nowadays disc space is cheap etc. Its not so much of an issue. My sort of point is that , with the fantastic new hdr, deconv etc, processing can take a long time, and occasionally there ...

After years of loving using ST, (2013!) I still realise that i do not understand some things. This topic is about saving files part way through the process. For example, lets say i load a linear osc file via open or compose, then autodev, bin, wipe, contrast and hdr. If i save the file then, what is...

Thanks Stefan, thats very helpful information.
I agree on your thoughts of superstructure after the NBAccents, makes great sense to me!
Thanks for taking the time to detail your process.

The broadband version with NBAccents is superb!
If you have any working tips on the module use for large nebula, please pass them on!
