Bug Reports / PI crashes while running Batchpreprocessing
« on: 2012 June 08 09:29:15 »
Running the script with percentile clipping as the rejection algorithm for Flat image integration results in the crash. Script works fine using default WSC or Min/Max for rejection. However, the default WSC rejection algorithm fails to remove stars present in my individual sky flat frames(I had only 4 flats on this run). So, changed to recommended settings in Vicent's tutorial ie percentile clipping and that choice results in the crash when the script reaches the the point where flat frame image integration is to run. Percentile clipping works fine when creating the master Flat without the script. I was able to get a satisfactory master flat using the script with the stars rejected by using min/max for rejection but I presume percentile clipping is preferred since it's the recommended rejection algorithm.

Tutorials and Processing Examples / DSE Tutorial
« on: 2011 December 08 01:32:51 »
Was just going through "The DarkStructureEnhance (DSE) Algorithm in PixInsight" tutorial and noticed that none of the mouseover comparisons for the various figures are working. I'm on a windose machine using the latest Firefox browser. Can this be fixed,  please.

Bug Reports / Unable to Save a Project
« on: 2011 November 10 21:00:23 »
Today when trying to save a project get error message(see attachment) and project fails to save. First time I've had this problem though there have been several updates since I last tried the Project save function. Need help to fix this.

Workshops and Conferences / AIC 2011
« on: 2011 November 06 19:57:42 »
I believe it was 3 years ago that Jack Harvey gave a PI workshop at AIC and had 8 to 10 attendees. As some of you may know, I was asked to give a PI workshop this year at AIC which took place 2 days ago. I thought the PI family here on the forums might be interested to know that this year around 100 astrophotographers attended the workshop, certainly a great sign of the increasing recognition of and interest in PI. I was delighted to see a lot of enthusiasm from many interested in learning more about PI. It seems clear that all the hard work and dedication to producing such an outstanding processing platform by Juan and his development team is really paying off. So kudos to Juan, Vicente, Carlos and all the others who contribute to making PI such a fantastic program. Keep up the great work.

Gallery / Hickson 44--Arp 316
« on: 2011 July 28 02:31:20 »
Hi All,

My fascination with distorted galaxies led me to this familiar target in Leo. The field includes a plethora of galaxies, the 4 most prominent comprise Hickson 44. The two distorted galaxies in the center of the image are NGC 3190 with it's prominent and distinctive dust lanes, and "S" shaped NGC 3187. These two along with the bright elliptical, NGC 3193 at 3 o'clock are also known as Arp 316. The spiral in the upper left corner is NGC 3185, the 4th member of the Hickson Group. A little over 14 hours of data taken with my RCOS 14.5", a STL 11000, and Astrodon Gen 2 filters. And, of course, processed in PI.

Gallery / Sh2-274 The Medusa Nebula
« on: 2011 July 04 23:13:59 »
Hi All,

Just completed processing of this interesting nebula in Gemini. Processed in PI following pretty much the same work-flow I've used and posted on some of my recent images. Different in this one was the incorporation of Ha data.  Ha was add to the Red channel using Vicent's method that was beautifully explained and demonstrated in Harry's recent tutorial. So, thanks to Vicent and Harry. The resulting new HaR channel was used as the luminance data and combined with the RGB master. Ha was not added into the RGB master.

Off-topic / Unable to Save a Project
« on: 2011 June 03 03:43:17 »
Trying to see how the Project function works and find that I can't save a Project. Have done some initial processing and trying to save several images with their Histories along with several Process icons. When I hit the OK button on the Save Process dialog I get the following error:

ReadPSF: Unable to lock parameter data for read-only access: isSimmetric

and the Processing Console indicates that Writing Project fails. The ReadPSF module is installed but has not been used on the images I'm trying to save nor is it's icon on the desktop.

Obviously doing something wrong so any help learning how to use the Project function appreciated.

Off-topic / Loading PSM file at start up in ver 1.7
« on: 2011 June 01 05:42:17 »
In Pi 1.6 I set it up to automatically load a psm file per Juan's instructions here:

http://pixinsight.com/forum/index.php?topic=1649.msg9619#msg9619

Want to do the same in 1.7 but the Code: open $PXI_COREDIR/startup.scp  doesn't work. Get error message "No such file exists on the local filesystem: C:/Program" so can't get to the startup script file to allow modification.

Must require a different code line to do this in 1.7. Please advise.

Gallery / NGC 3628
« on: 2011 May 26 19:21:39 »
Hi All,

Here's a familiar member of The Leo Triplet. Taken with a RCOS 14.5 and STL 11000, just over 17 hours of data. Processed primarily with PixInsight, PS CS5 for minor tweaking. I thought HDRWavelets did a great job helping to bring out the dynamic range in this galaxy. The well known tidal stream is evident to the left of the galaxy towards 10 o'clock.

Gallery / M 101
« on: 2011 May 13 04:52:41 »
Hi All,

Here's a second light image with the QSI583 wsg on a TEC 140 f7. While this is a familiar target, less often mentioned is that M 101 is another example of a galaxy distorted by a presumed near collision with another galaxy. Indeed, M101 is included in Arp's catalog, Arp 26. One of M101's companion galaxies is also in the frame, NGC 5477 near the right edge. Looks like a piece of 101 that's drifted away though I didn't read anywhere that that was the case. Here's the image.

All processing in PI save some final tweaks to a few of the stars with PS CS5. Comments always welcome.

Bug Reports / Error Message
« on: 2011 May 11 22:33:42 »
Have installed PI on new Dell Laptop(Win 7, 64 bit). All updates installed. When I left click on an open image I get a "PCL Win32 System Exception" error. See attached image of screen shot. When I close the error window by clicking on "OK" then the small read out window appears and won't close even when the error message closes. See second attachment image. After closing the error window, any time the cursor moves over the image the error message reappears. Generally the error dialog will close after the second click of the "OK" button, but eventually it won't close and the program must be closed with the task manager. Tried uninstalling and reinstalling PI but problem persists. Have PI  running on my desktop computer with no problems.

Hopefully there's an easy fix. Likely I've done something wrong during installation. Help appreciated.

Gallery / Another M 81_first light with the QSI 583 wsg CCD
« on: 2011 April 22 08:56:46 »
Hi All,

This is a first light image for me with this camera. Taken through a TEC 140 f7, a scope I've had for several years but haven't imaged through for a while. Guiding was with the Lodestar. The image is of a familiar target, M 81. Also evident is the dwarf irregular galaxy, Holmberg IX, and the IFN. The IFN was intentionally kept on the faint side so as not to overwhelm the main target. Processed with PI save final touch ups mostly with the clone tool in PS.

Off-topic / HDRWT question
« on: 2011 April 09 22:17:25 »
In the HDRWT module, what is the Overdrive slider doing? Couldn't find an explanation in the archives and it's not covered in Rogelio's Reference Guide as I guess the slider was added after he wrote it.
