FLAT FRAMES REORIENTATION IN PIXINSIGHT

[pixel]

Hi

I've downloaded the 1.8.5 version of Pixinsight and both times I've used it the flats have been made useless by pixinsight changing the orientation (shape) of each frame. The Darks, Bias and Lights remain good. Even when the flats are downloaded to my computer they look good however once opened in Pixinsight the frames are changed.

I use a DSLR.

Anyone had the same problem?

Hi,

Perhaps look at "Format Explorer" ---> "DSLR_RAW" ---> "Edit Preferences" ---> "Pure Raw" ---> "OK"

you can also turn off the tagging of the camera orientation in the camera firmware, but john's solution is the most correct path. another way is to give the format hint "raw cfa" in whatever process reads the CR2/NEF files if you want to avoid changing the DSLR_RAW handling globally.

Hi Guys

where would i find Format explorer, DSLR Raw, Edit Prefences, Pure Raw OK.

Apologies for my lack of technical knowledge will that process adjustment mention above be in pixinsight?

Hi,

From the top menu bar ---> view ---> Explorer Window ---> Format Explorer ---> DSL_RAW ---> Edit Preferences --- Pure Raw ---> OK

Look up

Rob the images are open as GRAY rather than RGB do you know how to correct this (All Dark, Bias, Flats and Lights)

this is correct, for calibration the images should be in 'cfa' format which is a mono greyscale image. if you zoom in on it you'll see it looking like a screen door or checkerboard pattern. you're looking at the raw sensor data.

after calibration of the lights, the next step is to run the Debayer process on the images, which will convert them from 1-channel mono to 3-channel RGB.

I'm completely lost I have no idea what your talking about. Why has all this changed from version 1.8 which had none of these issues.

In the past I was able to stack and process all in RGB no problem now I'm being told to do this in GRAY and then convert to RGB I purchased sometime ago the book by Warren A Keller "Inside Pixinsight" and none of what you suggest is in that book.

I know your trying to help but your being to technical I need someone who can explain the steps by step your assuming I know a lot more than I do. Maybe I need to go back to the 1.8 version as this worked fine.

If your going to help you need to explain more simply.  I have no idea how to convert calibrated lights from Gray to RGB.
