Wish List / Re: Tool Documentation not Available
« on: 2015 January 23 15:10:39 »
Thanks for your reply
I know there are other sources for finding out what the tools can do and they are very good but it would be so much easier (and helpful - after all we are all paying for a quality program ) if Juan (I assume he - or his team) would add a simple description in place of the annoying "Tool Documentation not Available"

Wish List / Tool Documentation not Available
« on: 2015 January 23 11:36:54 »
In Process Explorer there are a large number of processes which do not have any reference documentation associated with them and simply say "Tool Documentation not Available" when you click on them.
This is not very helpful for newbies (and others !) who are trying to find out what features are available and which process might be useful for a particular image.
I appreciate that writing comprehensive procedure documents must be very time consuming.

It would, however, really help if a brief description of what the tool is intended to be used for was added to each of the processes which would then encourage people to investigate the tool further. This would help to reduce the steepness of the learning curve.

I'm also surprised and concerned by the announcement. Fits is a universally accepted format for astronomical imaging and to produce your own format strikes of protectionism - Pixinsight is a well respected piece of software but it is not the only one - I'm sure there are a number of people that like to use Pixinsight alongside other astro software during their processing workflow.
I hope that you will continue to fully support the fits format and allow people to choose what format they use at all stages.

Don

ps It seems a very strange business plan to make your product less universally acceptable

In the last screen shot there was only one as I wanted to try a quick test with one dark, bias, flat and light.
Originally I used 3x3 minutes - I know thats not really enough but they often say that the QHY8 doesn't really need any as I don't get very many hot pixels.

Thanks guys
Following your suggestions I fiddled around with the settings and agree that the problem is with the Dark optimise check box.
If I leave it unchecked everything works much better - see attachment of result with single file of each.

Don
ps I was using a QHY8 - OSC

Thanks Steve
The Darks were 3 minutes as original lights and weres taken immediately after completion of light series
I've tried calibration again using a single image and four different combinations
Used Bias, Dark & Flat
Used Bias only
Used Dark only
Used Flat only

See Ist image for settings and second for results.

Image calibrated with Bias, Dark & Flat only showed brightest stars
Image calibrated with Bias was very similar to original uncalibrated image
Image calibrated with Dark only showed brightest stars
Image calibrated with Flat was overcorrected for vignetting compared with original

I expect I'm doing something simple wrong with the settings but can't figure out what.

General / Calibration Problem
« on: 2012 September 16 11:22:19 »
Hi
I hope someone can help me
I've just started using Pixinsight 1.7 and am having a bit of a problem
When I tried to calibrate images of NGC6888 with Darks, Bias & Flat frames the resulting image only had the very brightest stars visible even when viewed with Screen Transfer Function. See the 4th image attached below.
I experimented on a single image and found that if I just used one uncalibrated flat all of the stars and nebula were still visible – although vignetting worse than for the uncalibrated light –and if I used a single calibrated flat only the brightest stars were visible and vignetting even worse – all of the above when viewed with STF.
I've attached a screen shot to show you what I mean.

Top left is a single uncalibrated light
Top right is a light with an uncalibrated flat
Bottom right is an uncalibrated flat
Bottom right is a calibrated flat

I tried again using the Batch Preprocessing script and it terminated with an error message as below.

When I looked at the output images they were also generally as for my single image attempt.

Thanks in anticipation
Don

ps
