QHY8 Mirror Flipped Images + Preprocessing Script
« on: 2012 June 28 10:13:37 »
I have two questions.  I use a QHY8 camera and Nebulosity 3 as a capture software, set to record subs as  RAW images in ".fit" format.  I'm using Windows 7.

#1 - When I load such an image into PixInsight v1.7 x86_64, it comes up mirror reversed.  It is not simply "rotated;" I have to perform a "Image/Geometry/Vertical Mirror" operation before the view is correct.  What parameter am I setting incorrectly to make this happen?  (The image loads correctly into Nebulosity 3, and these results are the same whether I use Nebulosity 3 or EZCap for capture.)

#2 - When I attempt to use the PixInsight Preprocessing Script on my QHY8 images, they refuse to load.  I get this message: 

=== 0 of 1 frames were added ===
Unable to determine frame type: C:/Users/Rich/Desktop/Astrophotography/Sagittarius/062012-Trifid-QHY8/Trifid_001.fit

As noted above, I can open the image in PI just fine (albeit mirror-reversed), but when I try to run the preprocessing script (Script/Batch Processing/Batch Preprocessing), I get the error message.  Can someone help me with what I am doing incorrectly?

Thanks!

on #1, you need to change the fits reader directionality. there's a checkbox in the batchpreprocessing script, or if you want to 'permanently' change it, open the format explorer, double click on FITS, and change the chooser to up-bottom or bottom-up or whatever is opposite of what it's set to now.

Dear Daniel F and Pfile,
Terrific!  Thank you both!  It is wonderful to have such clear, ready help for a novice to whom such matters seem esoteric.
