How do I write_Images every n seconds [2]
I can use Write_Images to record every frame as a separate image, but I have a camera that integrates over time up to 10sec so t...		 10 years 2 921
Control of electron-multiplying gain in EMCCD cameras
An Electron-Multiplying CCD (EMCCD) uses an electron multiplying structure built into the sensor to obtain high sensitivity in l...		 11 years 1 998
rotate and mosaic [14]
That works!!!! It is a bit of a fiddle, but it does tile the second camera on a translated image of the first. I had to use a Ma...		 10 years 13 1457
rotate and mosaic [13]
Thanks STeven. Yes, if I can translate and paste several individual images into a larger image area that allows overlap, that sh...		 10 years 13 1457
rotate and mosaic [10]
Ok, to avoid the shear I must simply choose the Mosaic Image Size sufficiently large... my mistake.

rotate and mosaic [8]
This does look promising. I see that the mosaic images are no longer limited to 230x240 in the latest RoboRealm 1.8.10.3; this i...		 10 years 13 1457
rotate and mosaic [5]
Thanks, that looks like an interesting program, and stitching automatically is a big advance on other stitching programs I've t...		 10 years 13 1457

Darkfield Subtraction
OK, now I want to go even further :-) and reduce the vertical striations that are due I suppose to the structure of the C...		 12 years 2 1958
Where is the hot pixel filter (salt&pepper) ?
CCD's show "dark current" noise with longer exposures when warm, which shows up as isolated bright "hot pixels". In low lig...		 11 years 6 2048
Where is the hot pixel filter (salt&pepper) ? [7]
That was quick work STeven. Thanks. Your documentation is also very clear and precise. A couple of comments. First a trivial one...		 11 years 6 2048
Where is the hot pixel filter (salt&pepper) ? [5]
Sorry, I hit the wrong button and posted my "Hot pixel" GIFs under Unknown Title. Here they are again for those following this...		 11 years 6 2048
Where is the hot pixel filter (salt&pepper) ? [4]
Thanks STeven. Actually I am not looking at stars, but at much more diffuse blobs in a neutron diffraction pattern, so that will...		 11 years 6 2048
Where is the hot pixel filter (salt&pepper) ? [2]
Here are a couple of examples of hot pixel background patterns from long exposures with completely different cameras, an EMCCD a...		 11 years 6 2048
Binning pixels to increase signal [6]
I took a while to find an example that other people could try, and finally it did not seem as useful as I had expected, though i...		 10 years 9 2389
Binning pixels to increase signal [9]
...And of course you can also do 1D-binning using the scale model in RoboRealm. Sorry, I didn't look at your Scale module caref...		 10 years 9 2389
Binning pixels to increase signal [8]
Thanks for confirming that STeven. Square binning is indeed generally sufficient for binning to improve images with faint featur...		 10 years 9 2389
Re:Normalization Fixed [8]
That's it STeven ! With approx. the same test scene as before I  now get the following for 40-30 normalisation...		 12 years 8 3745
Re: Integrate Module Updated [6]
Good work STeven. I downloaded the new version and tested it with my low-light Philips WebCam SPC-900NC. It now resets when you ...		 12 years 8 3745
