Many enthusiasts from beginners to experts are regularly using PRISM for different activities. Monitoring in their CCD camera or webcam, looking for comets, asteroids and supernovae, or by achieving great images that cover most major magazines. Looking for spectroscopy, photometry and plate solving features, PRISM is the software you need. The following images show the results obtained with PRISM by amateur / professional people. Hereafter, you will find some testimonies from several PRISM's users.

Laurent has been using PRISM for many years, and he has achieved remarkable results with. Please have a look to his web site where are compiled his images. All have been acquired (some in remote mode) and pre-processed using PRISM.
Stéphane is an optical engineer  at ESO (Paranal), and has published a lot of images, as well into his personal web site as well as APODs. All his images are processed by PRISM. 
We no longer introduce Thierry Legault! He's a perfectionist in astronomical digital imaging , and his website is very impressive. Recently, he is devoting his time in imaging the ISS orbital station ISS and the shuttle from the ground. The whole process requires a great mastery of the chain: from acquisition to final processing. PRISM is part of the success!
Richard is a "newbie" to PRISM and has been using it for some months. Here is his website where he presents his results.
Claudine has been using PRISM for many years and she has discovered many asteroids with it.
You can have a look to her web site
Alain is managing spaceobs in Chile (San pedro de Atacama) and is taking care of customer remote telescopes and carrying on-site observations.

Prism ... I have a long history with Prism. I was present, an orange in my hand for the modeling of the celestial sphere, while writing the first line of code of Prism with Cyril. A Day well foggy and rainy in an observatory mount, waiting for good weather. Since then, time has passed, and Prism has grown up too ... besides, at the same time, the world of astronomy. Prism and me is ten "double asteroid" discovered with using a 200mm telescope, at a time when it was still possible, 150 variable stars discovered, several hundred rotation curves performed on asteroids, thousands of astrometric measurements  on all kinds of items, millions of photometric measurements  to search for variable stars.

It is also, in recent years, the software that drives entirely my observatory ... the dome of the filter wheel, via the CCD camera, telescope, cloud sensor, the weather station. While this is done automatically and 700km away. I also owe him my best pictures ... some are unique. So, you guessed it, Prism and me are inseparable :-)
"Congratulations for the job! I do all my processings with Prism, and it's really great .... especially the pre-processings ....

It's nice not having to be behind the PC during that time! The new acquisition module self seems to be particularly interesting. Sure, we always want more too! "
"I like to use Prism. Very powerful yet, easy to access, verbose and well documented, it is very intuitive. For the beautiful image, its preprocessing works automatically and automatic withdrawal of the sky background are very effective. Using a large sensor (KAF16803), I particularly appreciate its management of hot spots (not limited in number) and the Sigma-kappa image stacking that gets rid my raw images of satellites or aircraft blemishes (who invite themselves).

From image capture, Prism controls a large number of telescope hardware, this is a decisive point when considering changing every day. From my eyes, the most comprehensive and most flexible of all software. Trying it and you adopt it.

PRISM chart is very comprehensive, with precise drawing contours of nebula, this is a real plus to prepare shots.

I do use, may be, only 10% of its possibilities, but these 10% fits my requirements perfectly well;-) "

"I started with astronomical CCD using Prism 97 and since then, I have remained faithful to it. Prism is so complete that I still discover new functionalities after years of use. Its great advantage is to include all the functions that an astronomer could hope for: Sky mapping, camera management, telescopes management, image management, plate solving, photometry, etc. script. I do not know any other software that can do the same. The only alternative is buying an expensive "suite" of software. With Prism, I have discovered more than 1600 asteroids in recent years and the quest continues, hoping maybe soon, to discover a comet;-) Long live to Prism. "
"I've been doing image processing for almost 30 years and so many changes occurred since ... The hardware has evolved above expectations, and the software too. Today, it is difficult to imagine observing without computers. We can theoretically use a digital camera and print their images directly. But poor results are guaranteed ... To achieve things properly, it is through image processing and dedicated software only.
It, then, enters a world that must be learned.
If one wants its observing time to pay off, it is far preferable to have a map of the sky to know what is going to be shoot, which star is going to be used for autoguiding, what the telescope control can point, and automate image pre-processing. There is a whole range of activities, ranging from making simple nice images with telescope piggy back, observing programs for scientific purposes. There are a lot of software available, some free, but generally doing part of the job. Others with a learning curve that is to much time consuming (UNIX software). Other commercial software are interfacing pretty well with other software, but the price of all these software put together is close to the price of a 20cm telescope. I have switched to PRISM a long time ago, because it does almost everything.
Due to my current activity, I have to use other software, but as soon as I can, I come back to PRISM. I see a lot of amateurs who are investing quite heavily in instrumentation and which makes their life complicated and painful out of bits of software that work when they want. Not buying software such as PRISM is really a bad money savings,, and frankly I do not know many people that switched from PRISM to another software. "

"When I bought my first PC, it was already running Prism !
I started to learn with it, by digitizing silver photographic images...
So I have a long and successful history with this software.

PRISM is the Pandora's box shaped into Russian dolls ... Even after 10 years of use, I think I used only 20% of capacity!

PRISM is obvious to all those who wish to develop a rigorous manner, within an area of user friendly pleasure.
I spent my time measuring comets positions. It's always with me, a very exhilarating feeling to control image capture chain from A to Z and produce high quality results.

To satisfy this quest, PRISM is somehow "my faithful technician night" exhibiting formidable efficiency at all times.
You will always lead to your most amazing astronomical projects.
You will not want to separate, so much so that other applications you have become so bland and incomplete.

"Universal PRISM software you need to survey the sky in peace! "

Jean Francois has been using PRISM for years to observe and process his images of faint comets.
