Observations Images and interesting observations taken with Gx series of
astronomical cameras
Here we present only a few examples of images and
scientific observations taken with Gx cameras. More complete lists
of images acquired with respective camera series are attached to the
end of each page describing particular series. These lists contain
also authors, used telescopes, exposure details etc.
There is also a slide-show of the best images of deep-sky wonders
taken with Gx cameras available in the Gallery section.

 | | The image shown here was acquired by Martin Myslivec with a
first C2-9000 production camera on the 400mm Newtonian telescope.
Despite rather modest exposure times, just 2.5 hours per LRGB channel,
the resulting image shows the famous M51 in incredible
details. (more...) |
 | M20 Trifid nebula | Updated: 22.12.2022 |
---|
 | | Famous M20 Trifid nebula images by CielAustral group
show this iconic object in real colors, captured through red, green and
blue filters, as well as in somewhat unusual combination of real-color
data with images acquired through narrow-band filters. (more...) |
 | | If there is a contest for the most aesthetically pleasing
image of a deep sky object, this image of M16 Eagle nebula by
Wolfgang Prompter would be among the finalists, at last according to our
opinion (esthetics is subjective). The chosen false-color palette and
framing of the faint structures in the nebula create beautiful
artwork. (more...) |
 | | The M51 Whirlpool galaxy in the constellation Canes
Venatici belongs among the most famous spirals on the sky. In fact, this
is the first galaxy, which spiral structure was discovered. Also, this
object in fact consists of two interacting galaxies in the process of
merging, which makes it even more interesting. (more...) |
 | | M27 is just a perfect planetary nebula to observe. It is
bright enough to be easily visible even in small binoculars. It is also
large enough not to be mistaken for a star. It is also not just a round
shape, but shows distinct brightening on the sides (hence the
Dumbbell nickname, although Apple core is much more
suitable in my opinion). (more...) |
 | | Moravian Instruments astronomical cameras are often presented
as tools for getting beautiful pictures of the deep sky wonders. But
Moravian cameras have also other side — they are
often used to gather scientific measurements leading to world-class
research. (more...) |
 | | We present one more totally breathtaking image from Wolfgang
Prompter. Imaging this iconic duo of interacting galaxies NGC4038,
appropriately nicknamed Antennae, in a few spare hours after
capturing another object, lead to surprising result. (more...) |
 | | We present breathtaking images of three galaxies, captured by
Wolfgang Promper with his new C3-61000 PRO camera on ASA telescope.
World class instruments, located in Namibia — a
place with very low light pollution and dark sky, combined with
Wolfgang’s experience, explain the exceptional quality of these
images. (more...) |
 | SH2-171 nebula | Updated: 2.12.2022 |
---|
 | | We received another first light image, taken with the
C3-61000 camera. This time it is the SH2-171 nebulosity complex imaged
in real (reg, green and blue) colors by Andrea Lucchetti. (more...) |
 | | This incredibly detailed image of the NGC6992 Veil Nebula in
Cygnus was captured by Martin Myslivec with his new C3-61000 camera on
the 40 cm f/4 corrected Newtonian telescope. In fact, this is the very
first image captured with the very first C3-61000 camera
sold. (more...) |
 | M104 Sombrero | Updated: 2.12.2022 |
---|
 | | How far can amateurs go in the pursuit to perfect their images
of deep-sky objects? Consider the image of the M104 galaxy, nicknamed
Sombrero, below. The iconic image of M104, captured by the HST,
surpasses it in resolution and details, but this is expected from
multi-billion dollar orbiting observatory with 2.4 meters mirror.
Otherwise, this image is very close to the best images from ground-based
telescopes ever captured. (more...) |
 | | There was a time when the KAF-1600 CCD sensor was an
indisputable king among solid state detectors. It was a dream sensor for
every amateur astronomer — huge resolution of
1.5 mega-pixels and 14 × 9 mm photo-sensitive area seemed like a miracle.
Even the ¼ area, 400 kilo-pixels KAF-0400 offered twice the
horizontal resolution compared to cameras available to amateurs these
days. (more...) |
 | | The CielAustral group of astro-photographers chose to say
goodbye to 2020 and welcome 2021 in a very specific way – by imaging
NGC2020 and NGC2021 together. (more...) |
 | NGC6188 nebula | Updated: 10.9.2021 |
---|
 | | We already published an image of NGC6188 nebula complex on our
title page, taken by a famous group of astro-photographers named CielAustral. But
this was only a partial image of this large cloud of interstellar
matter. Now the same group presents almost 48 megapixels image mosaic,
covering much wider portion of the sky and allowing us to admire
incredible details in the gaseous structures. (more...) |
 | | NGC4725 and NGC4747 galaxies in the constellation Coma
Berenices are angularly smaller and also dimmer compared to big and
bright spirals like M31 or M81. Therefore, these galaxies are much less
often imaged and generally less known. Still, high quality image shows
them in their full beauty and details. (more...) |
 | | Comet C/2019 Y4 (Atlas) disappointed northern-hemisphere
observers by breaking into pieces and thus it will not reach the
brightness everybody hoped. But another comet C/2020 F8 (SWAN), visible
from the southern hemisphere, evolves into beauty and
brightness. (more...) |
 | M82 Cigar Galaxy | Updated: 4.12.2020 |
---|
 | | The M82 is also known as The Cigar Galaxy. It can be
seen close to more famous spiral M81 Bode galaxy in the
constellation Ursa Major. While the bigger and brighter M81 shows nice
spiral structure, somewhat chaotic appearance of the smaller M82 caused
the galaxy was considered to be irregular. Only recent observations in
infra-red light revealed also M82 has spiral arms, only not that
prominent, because we see the galaxy almost edge-on. (more...) |
 | | NGC2264 in the constellation Monoceros is both star cluster
and nebula. Visual observers nicknamed the cluster Christmas
Tree, because the brightest stars create a wedge-like shape,
resembling lights on a Christmas tree. Astro-photographers often use
another nickname — the Cone Nebula,
because of a distinctive cone of dark nebula, extending from the tree
top. It is visible on long-exposure images as a silhouette on the
deep-red glowing hydrogen clouds on the background. (more...) |
 | | CTB 1 nebula in the constellation Cassiopeia is a remnant of
an ancient supernova explosion. The nebula very low brightness is
obviously a cause it is imaged much less frequently than brighter and
thus more popular nebulae. (more...) |
 | | If we rank nebulae in the constellation Orion according how
bright or known they are, M78 nebula in probably only on the third
position, after famous Great nebula M42 and Horse Head
with Flame nebulae duo. Being smaller and dimmer than their
counterparts, imaging of M78 requires more effort to get good image, but
the result may be more rewarding. At last, there are far less images of
M78 all around the Internet. (more...) |
 | | Today we present another masterpiece from the
CielBoreal/CielAustral group of astro-photographers (Laurent Bourgon,
Jean-Claude Canonne, Nicolas Outters, Philippe Bernhard and Didier
Chaplain) — the NGC1365 barred spiral galaxy in
the constellation Fornax. (more...) |
 | Cygnus nebulae | Updated: 24.2.2020 |
---|
 | | Is the Universe empty or full of stars and nebulae? This
depends on what empty means to individual people. If you
imagine a star like a small water drop, another water-drop sized star
will be tens or hundreds of kilometers away. And this is valid only for
galaxies — rather isolated islands of matter
millions of light years apart. Space among galaxies lacks even these
water drops. (more...) |
 | Taurus Cloud | Updated: 24.2.2020 |
---|
 | | The best Christmas gift for us is to hear from users satisfied
with our cameras and to see their wonderful images acquired with them.
Leonardo Orazi acquired the G4-16000 camera just prior Christmas and now
we received very short e-mail from him, just two lines. The first line
says Incredible camera … great job and the second line is the
link to the first-light image taken with the camera. (more...) |
 | Rosette nebula | Updated: 8.1.2020 |
---|
 | | Scientific and aesthetic astronomical
imaging split only recently. Images of galaxies, star clusters and
nebulae, published in popular astronomy books only a few tens of years
ago, were mostly captured for research purposes. When a state-of-the-art
technology like CCD cameras, wide-field optics, precision telescope
mounts and powerful computers become accessible to amateurs, the very
best images of deep sky wonders start to be captured by amateurs for
pure joy and satisfaction from beautiful universe. Still, sometimes they
illustrate some interesting and important astronomical phenomena, like
the birth on new stars on the Rosette Nebula image acquired by Thomas
Lelu. (more...) |
 | Corona Australis | Updated: 3.1.2020 |
---|
 | | This beautiful image of part of the Corona Australis
constellation shows numerous dark nebulae, barely glowing in the
scattered light of remote stars belonging to our Milky Way galaxy. Some
portions of interstellar dust, reflecting the light of a nearby hot
stars, shine in blue-green color. The globular cluster NGC 6273, visible
in the right portion of the image, is much farther than the nebulae,
beyond the Milky Way disk. (more...) |
 | | It is virtually impossible to find a deep-sky object, which
remains out of sight of amateur astronomers these days. While everything
on the sky is already imaged many times, taking astrophotography
ourselves brings joy and satisfaction, when mysteries of the universe
reveal themselves during processing and stacking of acquired
images. (more...) |
 | Leo Triplet | Updated: 3.1.2020 |
---|
 | | Small camera — great image. Thomas Lelu
uses his G2-4000 on 10” corrected Newtonian telescope to produce
beautiful images. Three galaxies in the constellation Leo are often
denoted as Leo triplet. (more...) |
 | | We all used to the fact, that long exposure photography
reveals cosmic structures so dark, that human’s eye cannot see them even
in very large telescopes. What’s more, light from gaseous nebulae can be
enhanced using narrow-band filters (more precisely, narrow-band
filter of course cannot gain the light from nebula, but it very
effectively suppresses disruptive background sky light, so it cannot
overwhelm faint nebula glow). (more...) |
 | | NGC 7023 “Iris” nebula in Cepheus is a popular target for
astro-photographers. Its blue-green color is caused by reflection of a
light from a 7th magnitude star in its center. But the nebula itself is
much greater than the shining part around the bright star, only the
majority of its gaseous clouds remains hidden in shadows. (more...) |
 | | CCD cameras caused revolution in astronomical research,
similar to introduction of telescope and more recently to the usage of
photographic plates, capable to accumulate light during long exposures.
We very well understand that the beautiful pictures of the deep-space
objects, out of the reach of human eye regardless of telescope used, are
very attractive and majority of our users enjoy them. But still,
astronomy is a science and scientific research is very important
application for our cooled CCD (and CMOS) cameras. The image presented
here shows so-called light curve of recently discovered double-eclipsing
quadruple star system. (more...) |
