Capturing with Nebulosity 3 and all the next with PI? Neb 3 configuration.

[fhuet1]

Hi,

Until now, I've been using a workflow based on a Windows system, as I had no guiding camera Mac Osx compatible.
Now, I have a Starbright Lodestar guiding camera which can be used on a Mac with PHD Guiding.

On Windows I used BackyardEos to capture (with a modified Canon 40D), PHD for guiding and all the image processing with PI.

I use for integration that tutorial:
http://www.astrosurf.com/astronosur/pixinsight/preprocessing-1.htm

Or on the last images, the PI Batch Preprocessing Script.

But I'd like using an ALL Mac Osx process.

The only capture software that includes a Fine Focus routine (at least I've not found any other) on Mac is  Nebulosity 3.

Giving that I only want to capture as I do with BackyardEos, and do all the resting process with PI,
Which Nebulosity 3 configuration do you recommend me?

All the fits I got from Neb 3 are Black and white (the CR" are in colour mode)!
And the fits headre info is always: BZERO   =  32768 / offset data range to that of unsigned short
and not 65535 as read on other posts.

I have doubts on:

Using only the CR2 files and discard fits?
DSLR 16 bits scale activated?
Save in 32-bits floating point?
Color file format as Maxim type?

The optimum for me would be to get the same CR2 files as on BackyardEos and do the same process I do now on Windows...

Thanks
Fernando

CR2, or raw files, are not in color. It may be that the program you used to look at them was debayering the files on the fly, but I can assure you, the raws are all b/w.
So Nebulosity behaviour is what I would expect. You just have to debayer the files at some point in your workflow, usually after calibrating with bias/dark/flats, and just before aligning.

I do my capture in Nebulosity (although version 2.5). But I don't use the FITS files. I have Nebulosity retain the CR2 files and use those. There is a preference for DSLR save location that has a "Computer FITS and CR2" option. Unfortunately I don't think there's a way to only save the CR2 so you have to have use the storage space for both even though you only need one or the other. Don't forget to set the Acquisition Mode to "RAW Acquisition" too.
