General / Re: Images fail to register

Thanks Rob,
I checked the calibrated and debayered files and it seems the flats I have been using screw up the calibration process. Seems to work better without flats.
Cheers Grant

Hi Rob,
I have just read on a recent PI forum post that the dcraw import is probably causing the problem, as it clips the images. I apparently need to run LibRaw but I don't know how to do that. Can you assist?

General / Images fail to register
« on: 2017 December 14 17:13:54 »
I am trying to process images from a new Pentax K-1 camera (35Mp) and I am using batch preprocessing. I get to the image registration section and the program fails with the message saying cannot match stars. I have tried to increase the noise level settings but without success. Can anyone suggest what other things I can try?

General / INDI Device Controller
« on: 2017 August 03 16:19:05 »
I am looking at using the INDI module to drive my scope and camera, and wondered if there was a walk-through or tutorial on the process?

Thanks, I will give it a try.
Cheers Grant

My problem is getting the star mask right. Any suggestions on settings?

Forgot to add this comet Lovejoy C/2014 Q2 which is clearly visible in our southern skies at the moment.

Bug Reports / Comet Align Tool does not work with xisf files
« on: 2014 December 23 02:46:53 »
Hi All,
is it correct you have to convert all the xisf files to fits files before running the comet align module. It says it can't find the time/datestamp.

Image Processing Challenges / Need a star mask for a comet merge
« on: 2014 December 23 02:38:36 »
Hi All,
I have been trying to blend a background star field with comet image (stacked using the comet align module) but although I have tried to follow the tutorials in PI-3, I still can't seem to be able to work it out. My problem is trying to determine to correct parameters for the star mask. I have attached the star field image. The images were produced from 80 x 1 minute subs.
Is there someone who can assist with creating a star mask for me so I can merge these images, and if so, which files do you require? I can post them on dropbox.
Regards Grant

I am just using single images of nightscapes - 25 second exposures at 3200 ASA. I am opening the ARW files via the file open command, then debayering. I don't seem to be able to get the colour balance right, even with extensive fiddling.

Hi All,
I have been trying to use the ARW raw files from my Sony NEX-7 camera but when I process them in PI, I cannot get the correct colour balance. Any suggestions?

Hi All,
I have GeoTiff file comprising an UnSigned 16 bit integer 4 band multi-spectral file and I don't seem to be able to import it with PI seeing the 4 seperate bands.  Any suggestions?

Tips & Tricks / Superluminance for OSC images
« on: 2014 August 02 18:54:09 »
I have heard that creating a superluminance from OSC images may enhance the detail in OSC images. Can anyone comment on this and if this is the case, suggest a work flow to create a superluminace image?

Wish List / Re: Principal Components Analysis

Hi Juan,
many thanks for the reply. I have been encorouging fellow geoscientists to use PI for their image processing so hopefully you might have got a few extra sales! Understand the issues with competing resources. Any idea how much it might cost to have someone write the module for this?
