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.

Novae discovered in M81 galaxy using G2-3200 CCD camera on 10 inch telescope	20.6.2008

Although absolute brightness of a typical nova can reach -7 or -8 mag, we can see it only as a star shining at 19 or 20 mag, when it explodes in the M81 galaxy 12 millions light years away. This is why telescopes with meter-class mirrors were used to search for them in such a big distance. But with a CCD camera capturing almost 90% of incoming photons, a telescope as small as 10 inches can be used to discover them.

New Nova in the M31 Andromeda Galaxy Found	10.5.2007

Kamil Hornoch, amateur astronomer awarded by the “Amateur Achievement Award” of the year 2006 by the Astronomical Society of the Pacific, found his 43^rd nova in the M31 “Great Andromeda Galaxy”. This time he used his new G2CCD-1600 camera.

Astronomy Images Taken by G2CCD Cameras	11.1.2011

Number of G2CCD camera users take nice images of deep-sky wonders. Some of them are presented here.

G2CCD-1600 first light images	15.1.2007

Recently introduced KAF-1603ME based CCD cameras prove their capabilities to gather precise scientific data (e.g. in exoplanet transit observations) as well as to capture beautiful images of deep sky images. We introduce some very first images obtained with the G2CCD-1600 prototype.

Exoplanet XO-1b transit observations	15.1.2007

The XO robotic telescope found slight brightness variations of the star GSC 02041-01657 in Corona Borealis on the beginning of year 2006. Consequent photometric observations, performed by amateur astronomers, confirmed very slight 0.03^m brightness drops repeating every 3.94 days. The 193^rd exoplanet was discovered—the star was named XO-1 and the newly found planet XO-1b. It is only 10^th exoplanet found by detection of planet transits. How difficult is it to actually observe the exoplanet transit?

73/P Schwassmann-Wachmann	29.9.2006

Comet 73/P passed exceptionally close to Earth on May 2006. It was not very bright so imaging it while speeding across the sky was a challenging task. On the other side computer processing of acquired images can create interesting views.

2003UB₃₁₃—the 10^th planet or only the biggest known KBO?	15.1.2007

At 97 AU from the Sun and about 3000 km diameter, the Kuiper-belt object 2003UB₃₁₃ gleamed only at 18.9^m on January, 2006. Although slightly bigger than Pluto, this object appears about 100× dimmer. Still amateur astronomers can capture it with backyard telescope and CCD camera.

How Deep Can You Go?	29.9.2006

High-quality CCD camera promises converting of majority of incoming light into information. Another important feature is keeping system-induced noise as low as possible to maintain good signal to noise ratio. Regulated chip cooling and system read noise limited only by the CCD chip itself is a must for scientific-grade instruments. So what is the limiting magnitude for typical backyard telescope?

G2CCD-0400 Deep Sky Images	7.8.2006

First shots with the production G2CCD-0400 camera show its capability to capture beautiful images of deep sky objects.

G2 CCD Camera Prototype First Light	27.1.2006

The first prototype of G2 CCD camera acquired first light on June 2005. Although the camera mechanics and electronics were somewhat changed from that time, the overall shape is almost finished.
