to its powerful Maximum Entropy Deconvolution function (MaxEnt) and its ability to driver most of CCD cameras, MaxIm DL/CCD became a product
acclaimed by all astrophotographers working with digital images.
DL/CCD includes "MaxEnt", a sophisticated tool able to enhance features lost in blurry images.
This tool comes with an automatic Point-Spread-Function (PSF) to extract
star image, Gaussian or Exponential curve, noise extraction from models
and a wizard to make the tool more easy to use.
DL/CCD supplies also standard imaging tools to alter pictures both in geometry
and colors (even in false color), it can align pictures for a later B/W or
color combination (including LCMY) or extraction, resize with
interpolation, remove bad pixels or stretch the image. You can also easily
postprocessed your images with the advanced imaging filters like FFT,
Kernel, High and Low pass, unsharp mask, all functions including a preview
marvellous software is completed with MaxImDL/CCD Camera Control able to
driver with accuracy most CCD cameras and filter wheels (AP, Astrovid,
Celestron, Meade, HiSIS, SBIG, webcam, etc). You set the exposure, focus,
binning, color sequence (if need) and control the autoguider (even asking
it to take some pictures) through a simple menu. Once recorded, MaxIm
DL/CCD includes a CCD image Calibrator supporting bias, dark and flat
field frames for preprocessing. All these functions make of MaxIm DL/CCD a
product I warmly recommend to all CCD users.
the beginner, MaxIm DL/CCD comes with a powerful on-line help with
examples (including 70% of the manual) and a detailed 250 pages
DL/CCD can read RAW images recorded by DSLRs or CCD cameras, and supports
in reading and saving 32-bit FITS, 16-bit TIFF, SBIG, PC-Lynxx, PNG, BMP
and JPEG formats.
at version 5, MaxIm DL runs on all Windows platforms. No update nor upgrade
is required for Windows XP, Vista, or Seven.

by Gregory Giuliani, PRiSM is a complete software, including in this new release a planetarium, an
image processing tool, a telescope driver, and more.
It was selected by several professional observatories worldwide from
Pic-du-Midi to MMT and ESO. Version 10 was elected as "Hot Product
2016" by Sky & Telescope.
Polar alignment using the King Method is simple and our pointing model capability will ensure your mount is always on target.
image processing module of PRiSM allows you to preprocess (background and
bias compensation, normalization, dark frame, flat field image, etc) or
postprocess your digital or CCD pictures. It includes all useful functions
as filtering and trichromy with sub-pixel alignment, without to forget the
standard arithmetical and geometrical operations (addition, substraction,
enlargment, mosaic, planisphere, etc).
Sophisticated image tools allow easy identification of your best images.
PRiSM also includes photometric and
astrometric tools (data reduction and more), on par with MIRA Pro.
parallel, PRiSM can drive some CCD cameras (Audine, FIERA, Hisis, KAF0400,
SBIG, MX5, etc) and telescopes interfaces (LX200, Celestron Ultima, Sky
Commander, NGC Max, Micro-Guider, Eureka, Ouranos and is compliant with
Very Large Telescope TCS) including PEC support, MCMT encoders and
new version has a fully automatic observation function from opening the dome
or roof, cooling the camera, auto focusing, auto centering the target, and
capturing images. It can even warm up the CCD camera, park the telescope and
close the roof or dome. It will even monitor your weather station or cloud sensor
to make sure you get as many observations as possible from your imaging system.
also the software part of this review for an overview
of the planetarium module (version 4).

third screenshot is the one version 9 advanced.
at version 10, PRiSM runs on all Windows platforms.
freeware and open source
ESA/ESO/NASA FITS Liberator is an image processing
software supporting only FITS and PDS formats and saving only in TIFF
format. It uses is thus limited for amateurs and mainly reserved to those
taking LRGB images.
is the raw image standard used by all professional observatories like ESO
VLT, CFHT, NRAO, AAT, space telescopes like Hubble (HST), Spitzer, XMM,
and planetary probes like Cassini–Huygens or MRO without to forget your
personal FITS images recorded with your CCD camera.
Liberator includes a faster and more streamlined workflow than the
previous version. The CPU-intensive calculations have been optimised, allowing time savings
of up to 35%. For large images the savings in efficiency are even more
pronounced, also thanks to a delayed application of stretch functions.
sustain the future development of the software the entire source code
-about 30000 lines of code - is being released as open
source, and anyone wishing to contribute to future versions of the
programme may do so.
Liberator is now at version 3 and works on MacOS X and all Windows 32-bit and 64-bit platforms.
program is 5 MB in size and installs in a few seconds. Note that for
a same resolution, a FITS image is usually 3 to 4 times larger than
a RAW image recorded by an DSLR.
You will find FITS images on the
CFHT Science Data Archive.
Here is a sample FITS image of M57 (2.3
that FITS is most of time not supported by amateur software, not even by
Photoshop CS and any viewer, excepted in adding them a plugin. So, if
you are searching for a software supporting FITS format, for viewing or
editing, you will find additional tools and converters on the GSFC-NASA
website. FITS format is also supported by MaxIm DL,
MIRA and IRIS among others.

electronic manual in Adobe Acrobat format.
particularly interesting application is able to load multiples
files doing a multi-selection. It includes basic image editing
functions to alter
images (geometry, color or luminance) but also more powerful tools like
perspective correction, photomontage with scaling and warping.
standard arithmetical functions there are some dedicated to pure
photography. Various retouching tools for example allow you to work with
scratched negatives or prints. You can paint and clone features to remove
imperfection, lighten or
darken selected areas of an image. A color
correction transformation adjusts skin tones in a portrait without
altering the others colors in the image, tint transformation colorises B/W
images, Red Eye tool lets you suppress the red pupil when a flash is used,
The Mask dialog box contains
a Color Similarity tool able to erase undesirable features by dragging an
input color or range of colors over another region of the image. The Light
Falloff transformation allows you to compensate light for the tendency of
some lenses to produce unbalanced image. The Color gradients fades
smoothly one color in another. The lasso tool and similar masks allow you
to suppress undesirable backgrounds. At last like in many similar products
some special effects tools are available including vignetting, distorting,
embossing, edge enhancement, spiral, etc.
astrophotography and post-processing purposes, other functions like an
image blinking comparator is provided to find moving or new objects, a
Stereo transformation prepares pairs of stereo photographs and, last but
not least you can create composite by accurately registering and aligning all
images so their data be combined pixel by pixel to create a high resolution B/W or RGB
composite. This tool includes a preview mode and various filters to
lighten, darken or add, blend, etc your composite.
to the previous releases 2.5, version 3.x support color management too,
a color match output, a new smart brush mode, new support for displaying
and editing file comments added by digital cameras, a web slide show and
new transformation tools (rotation during cropping, fan effect, shadowed
text and more).
Window Pro supports 16-bit B/W and 48-bit color images and can exchange
data in numbers of formats including BMP, FITS, GIF, JPEG, RLE, TIFF with
full Photo CD support and TWAIN-compatible scanners.

It supplies a dynamic threshold, some geometry alterations plus
usual filters and last but not least an unsharp mask.
It can also be connected
to external databases on CD-ROM as GSC, TYCHO-2, USNO-A, QMiPS32 or MicroCat.

CCD users will find its numerous advanced filters very useful. There are
for example the classical arithmetical functions like add, substract,
average (median sum), functions like logarithmic scaling and unsharp
masking but also the famous Maximum Entropy or Lucy-Richardson restore
functions and a Radial
Gradient to enhance the sharpness and details of your pre-processed images.

program is quite similar to Picture Window Pro and comes with a very
convenient help menu as well a computer status.
main advantage is to use dynamic tools or toggle which display in
real-time the effects of an alteration, the number of pixels replaced,
etc. It includes standard alteration functions on images geometry or color
saturation and provides a small pixels editor. Layers can also be sent
back or in the foreground and a text can be add to your images.
pre-processing features like Dark & Frame use offset, dark frame and
flat field images to substrat all errors when using a CCD camera. Of
course this option is a time-processor hungry even of fast Pentium III
systems. It is completed with a Kill Warm and Cool pixels function.
by imaging experts, there is a specific Operations menu which includes
filtering functions like Convolution and Out-Range and the famous Maximum
Entropy and Lucy-Richardson restore algorithms, both using the PSF
to compute the stars profile.
but not least, CCDPro allows you to split a color picture in its RGB
components or to create color composites from accurately aligned B/W
layers, to modify the contrast, brillance, the size or even the X,Y shift
of each of your layers.
sides, by definition the RGB split cannot extract the luminance channel
although the Multi-Layers submenu can create a LRGB picture. The zoom is
limited to a range 8:1-1:8 and there is no gamma corrector excepted by
creating a mask. The pixel editor replaces only pixels by averaging its neighbors

relatively complete product with colorful icons including all basic image
processing of cooled CCD images (dark-frame and flat-field correction,
level adjustement). A special digital develpment function allows you to
show natural tone in CCD images by sharpening edges according to the
brightness in the image. This tool emphases details in images by using an
hyperbolic function to convert the gamma characteristic.
image processing functions ensure various adjustments that complete

are some filters like a quite simple unsharp mask, bluring and sharpening,
enhancing edges and masking (color emphasis). StellaImage can also
combines images to reduce the noise, adjust the input pixels to darken or
highlight areas and combine RGB or LRGB images to create color composites.
To interpret a contrast, an histogram of image tones is available as well
as a palette to create a four false colors image.
all functions display a preview and the undo is hidden in the pull-down
menu. StellaImage can directly control Twain scanner and read normal
photographs. Now at version 2, StellaImage is provided without support and
runs on all Windows 32-bit platforms.
to use, full of icons it is pleasant to use at first run. Although it
looks like MS-Photo Editor it is more powerful than its concurrent. Its
interface is accessible to all even to beginners without much
sides, PSP on-line help is very convenient and answer to all your waits.
More easily than probably some other products, it can alter images,
both in size and colors, create special effects, adjust hue of a specific
layer or extract the outline of an object (magic wand) to create masks,
etc. You can also place a text on a path and bending it
to any custom shape. It contains all paint tools you need, use vector
drawing tools, a color gradient editor and a capture module.
You can also add watermarking for embedding and
reading copyright in your images. PSP manages thumbnails too in various
sizes, an easy way to
browse your subdirectories in place of using the standard explorer searching for
a specific image.
PSP comes with a
second application call Animation Shop2 able to use AVI and Autodesk
animations formats. At last
through its Twain interface, it provides
direct support for many of the most popular digital cameras.
at version X3, PSP can export in transparent GIF and JPEG and supports PostScript and Adobe
Photoshop PSD formats.

program is pleasant to use and really powerful. It looks as if it was
designed with the end-users requests in mind. For example, the menu
toolbar is user definable and many tools can be extracted from the toolbar
and moved on your desktop if necessary. In case of problem you can always
take a look at the on-line tutor, not complete but useful for
many modern products it can directly acquire images from scanner or
digital camera. It uses all standard image alterations tools and give you
also the opportunity to manipulate 3D models. Masks and transparencies
haven't be forgot. You can create them, add them to your original and
enhance this way your images in a few mouse clic.
Scrapbook is also available to drag-and-drop objects from your CD or any
FTP site, to find files and folders. All images can be displayed as
unusual qualities it can create movies and save them in AVI or GIF
format. That means that it can also read animations GIF and alter its
individuals frames as any other picture. Among its special tools you can
select a part of an image and transform it as you want or use the
predefined special effects. All tools you are using open a small floating
windows in which you can optionally see a preview of your alteration. You
can also use a scripting module to automatically create text or background
with special appearance.
Color and printing are spectacular as it is able to manage up to 48-bit
RGB images, to convert to NTSC or Adobe Postscript3. It can load or save in
over 70 files format.

is something common with MIRA in this software. Written some years ago in
C and assembly languages, this 32-bit program is the fastest I know,
comparable to SUN or VAX workstations and able to display very large
images over 2 K-pixels by side, depending your available memory. More
expensive than MIRA this is in my humble opinion its only competitor.
are some of its features : X and Y real-time plots, interactive histogram,
box sum for photometry, interactive 8-bit false color, tricolor merging,
linear and logarithmic displays, histogram equalization and more.
addition it supports numerous mathematical functions including image
arithmetic and functions, high and low pass filters, edge detection, FFT,
convolutions with various masks, detector flat fielding and you can also
create your own filter kernels.
the standard mathematical functions and filters it offers some photometry
routines like a point source function (PSF) to find stars in images,
background subtracted aperture photometry given relative magnitude and
fact thanks to its fast manipulation of large data this program is suited
for variable star studies, astrometry, supernova searches, optical
supports 32-bit images as well as 4 bytes per pixel real images and is
able to remap 96-bit colors space to 256 colors. It imports numbers of CCD
file formats, NASA IMQ, IMG or IBG format, FITS, GIF, ASCII and binary
files. At last it can drive a Meade LX200 and SSC series telescope and
control various CCD cameras.
at the time of its first publishing, the manufacturer suggested to use a
80386 with math coprocessor or higher CPU, 8 MB RAM and an SVGA 1024x768
display. A 24-bit display adapter is highly recommended.
1990, Astro Equipment, 1600 FRF (~$250)
a French product developed by professional astronomers and image
processing specialists. Using a professional-like GUI this is a program
similar to MIRA but simpler and voluntary dedicated to amateurs. It
includes more than 180 functions, among which standard arithmetical and
geometrical functions, filters like unsharp mask, Gauss, low and
high-pass, gradient, user-defined convolution and more. It is completed
with wavelets analysis, image restoration by deconvolution, FFT,
rotational gradient to enhance radial structures like comets, black optimization,
flat-field frame generator (median filter), polynomial gradient correction
and an expert programmation mode.
image analysis module is quite complete providing photometric measurements
and astrometric analysis (by centroiding calculation and stellar modeling)
to extract stars from the continuous background with error estimates and a
blink mode to search new objects.
visualization mode accepts bilinear zooms and B-spline, isophotes, 3D
views, trichromy, drawing functions and animations.
in the early 90's, this program runs on 80386 and higher processor with 2
MB RAM and SVGA monitor but negative point it only displays a maximum of
256 colors (an 8-bit display adapter is enough). So distracting artifacts
can show up in areas of subtle colors variation such as clear skies. Good
to know, dozen of raw images are provided with the program.
with the Microsoft Windows OS, this is a very simple product that a 4 years old kid can use to draw colored circles, box and write text in
various sizes and fonts and zoom in. Its
rotation tool beeing limited to flip in both directions and rotate at 90,
180 or 270°, I mainly use it for its ease to use, for its capabilitiy to fill in
an area with the
exact tint, for its free selection able to extract any custom part of the
image and to copy it elsewhere, its possibility of superimpose several
images, to mirror or reverse it, as many features that are not so easily
or quickly accessible in more powerful tools like Picture Window Pro or
Photoshop. MS-Paint can also be useful to create small plain
color bitmaps for illustrating purposes. MS-Paint saves only in
monochrome, 16 or 256 colors bitmap and 24-bit color. The
product is included in most Windows OS from 95 to Seven.
